We sincerely believe that your Wadia 850 will bring you many years of musical pleasure and satisfaction. While every new owner is anxious to begin listening, we encourage you to take a few minutes to read this manual and familiarize yourself with the full capabilities of the Wadia 850 Compact Disc Player. Q Brief History of Wadia Digital If you are in a big hurry to listen, please read the sections of this manual where the symbol at left is shown. Wadia Digital Corporation was founded in 1988, making it one of the oldest digital audio companies in existence. Wadia was formed by a group of engineers from Minneapolis-based 3M (Minnesota Mining and Manufacturing) who had compiled many years of experience in advanced digital and telecommunications research and development. In the early 1980’s, this group had become intrigued by the emerging CD technology. Disappointed by the sound of early CD players, they examined the designs and found them to be unsophisticated compared with technology available in other fields of design. In response, they founded Wadia Digital a company based on the philosophy of applying advanced technology to improve the performance of digital home entertainment equipment. Wadia’s first product, the Wadia 2000 Decoding Computer, was a breakthrough. For many listeners, it proved the viability of Compact Disc as a musically involving format. Ever since, Wadia has continued to develop on the original technology - refining, listening and improving along the way. Wadia’s modular designs mean that new technology is available to current owners in the form of cost effective upgrades. Here is a brief list of technological innovations Wadia engineers have pioneered over the past ten years: l l l l l l 1988: First outboard DA converter 1988: DigiMaster patented algorithm (filter optimized for reproducing music) 1989: First to apply glass fiber optics to home audio 1990: First to recognize jitter as a source of audible distortion 1992: First to perfect digital volume control 1994: First Compact Disc player featuring digital input capability Now in our tenth year, Wadia continues to re-define the limits of digital music playback. We are proud to introduce the Wadia 850, one of the most innovative design to date from Wadia; a breakthrough in sonic performance and a strong statement of our years of dedication to the pursuit of musical quality. 3 WADIA 850 COMPACT DISC PLAYER INSTALLATION AND SET-UP Unpacking Q Use care in unpacking your Wadia 850 Compact Disc Player. Inspect it for any shipping damage and call your dealer immediately if any is found. Do not plug your Wadia 850 Compact Disc Player into an AC outlet if you find shipping damage. We advise saving all packing materials so that the unit can be easily and safely shipped if the need arises. Accessories Provided with the Wadia 850 are the following accessories: AC power cord Four spiked feet with threaded studs Four steel coasters Remote Control Three type MA batteries l l l l l Installing the Spiked Feet With the unit still positioned on its side, screw one of the spiked feet into the bottom of each corner post. Position the Wadia 850 where you would like it to reside in your system. We recommend choosing a solid, non-resonant, level, surface for best performance. If this surface is susceptible to damage, place one of the steel coasters under each spiked foot. Q Do not tip the unit onto the back panel. This can damage input and/or output connectors. . l&J 4 WADIA 850 COMPACT DISC PLAYER CONNECTING THE WADIA 850 TO YOUR SYSTEM CHECK VOLTAGE HERE! Check to make sure your Wadia 850 Compact Disc Player has been manufactured for operation at your AC line voltage. Attempting to use your Wadia 850 Compact Disc Player at any voltage other than specified on the rear of the unit may damage the unit. Damage caused by improper operation is not covered by Wadia warranty. If the voltage specified is different from your AC voltage, contact your Wadia dealer. Connecting the Wadia 850 to AC Power Connecting the Wadia 850 Compact Disc Player Directly to a Power Amplifier The best performance is obtained when the Wadia 850 is plugged directly into the wall with the power cord provided. The Wadia 850 has power conditioning, surge suppression and an extremely sophisticated overall protection scheme. It should not be necessary to use surge protectors, power conditioners or aftermarket power cords. If you wish to experiment with any of these devices, work closely with your dealer and most of all, trust your own ears. Avoid allowing static shocks to be applied to the inputs or outputs. To prevent static shocks, touch any grounded surface, such as the Wadia 850 chassis, before connecting or removing a cable. It is unlikely that a static shock will damage the unit, but it may cause the Wadia 850 Compact Disc Player circuitry to “lock-up” (see Lock-Up under Trouble Shooting). Inputs and outputs can be safely connected to the Wadia 850 Compact Disc Player: 1. Before the unit is powered up 2. When the unit is in Relay-Mute mode (See Mute Modes in Genera/ Operation) We strongly recommend that you use your Wadia 850 Compact Disc Player connected directly to your power amplifier. Even if you purchased your Wadia 850 with the intention of connecting it to your preamplifier, we suggest that you try direct connection to your amplifier. Many listeners are surprised by the improvement in performance over even the most expensive preamplifiers. To connect your Wadia 850 to a power amplifier, ensure that your power amplifier is turned off, then simply connect your analog interconnects from the Wadia 850 analog outputs to the amplifier’s inputs. Using the Wadia 850 with a Preamplifier While the Wadia 850 Compact Disc Player was designed to be used without a preamplifier, no compromises were made in its design that will prevent excellent operation in a conventional system with a preamplifier. When using a preamplifier, bypass the Wadia 850 volume control by setting it to its maximum setting. WADIA 850 Optimizing the Output Level COMPACT DISC PLAYER Best performance is obtained when operating the Wadia Digital Volume Control in the top half of its range. If needed, the maximum output level of your Wadia 850 can be adjusted to match the overall sensitivity of your system so that the critical listening will take place with the volume control operating in the top half of its range. The maximum output level of the Wadia 850 Compact Disc Player is adjustable by means of a set of internal switches. The Wadia 850 is factory set at 4-2 volts to accommodate the most common range of system sensitivity. If you find that your typical volume level during critical listening is below 50 on the volume display, then it may be advantageous to use a different setting. The output level is not user adjustable. If you would like to change the output level, consult your dealer. Optional Digital Inputs/Outputs Your Wadia 850 Compact Disc Player can be retrofitted to include digital inputs and/or outputs. Consult your dealer for information on this option. Connecting Other Digital Components to your Wadia 850 If your Wadia 850 is equipped with the optional digital inputs, the configuration is as follows: Input 1: Glass-fiber optical Input 2: Coaxial with BNC connector Input 3: Coaxial with BNC connector Input 4: Plastic-optical TOSLINK The Wadia 850 will automatically adjust to the sampling rate of any of the standard digital audio formats. If your Wadia 850 is equipped with the optional digital outputs, the configuration is as follows: Output 1: Glass-fiber optical Output 2: Coaxial with BNC connector The digital output signal is active at all times when a CD is playing in the transport. Choosing a Digital Cable While the Wadia 850 supports several transmission formats for digital audio, we recommend using a high quality glass-fiber cable such as the one available from Wadia. Wadia Digital was the first company to use glass fiber-optic data transmission in digital audio. We have continually improved this format and believe that it offers the best, most consistent performance of all the available options. Based on our experience, here is a list of digital interface methods in descending order of performance: 1. Glass optical (as implemented by Wadia, with high quality glass optical cable) 2. Coaxial cable using BNC connector 3. Coaxial cable using RCA connector 4. TOSLINK plastic-optical cable The quality of any of these transmission methods depends on the quality of the cable and the sophistication of the transmitter and receiver. If you are using a coaxial cable we recommend that you have the cable terminated with a BNC connector. This will provide higher performance than an RCA connector. If you purchased the optional digital inputs or outputs, an RCA/BNC adaptor is provided. The adaptor can be used for experimentation between different types of coaxial cables. Again, we highly recommend that you take advantage of your dealer’s experience and, most importantly, trust your ears. 6 WADIA 850 COMPACT DISC PLAYER FREQUENTLY ASKED QUESTIONS Should I use a Balanced or Unbalanced connection? We recommend you use the balanced analog output from your Wadia 850 Compact Disc Player, connected to a true balanced input. All things being equal, properly implemented balanced (also called differential) circuitry sounds better than unbalanced circuitry. The Wadia 850 is a true balanced design. It generates the inverted signal in the digital domain and all subsequent processing is done in balanced mode. Your Wadia 850 is designed to maintain many of the advantages of true balanced design when using the unbalanced outputs. In addition, the Wadia 850 output stage is capable of driving both types of outputs simultaneously. The balanced outputs use the standard audio pin configuration: pin 1 is ground, pin 2 is positive, and pin 3 is negative. Why should I bypass the Preamplifier? A preamplifier is unnecessary when using your Wadia 850 Compact Disc Player. The Wadia 850 provides all the necessary control functions of a preamp while the signal is still in the digital domain. This avoids the sonic degradation caused by analog circuitry, switches, and wire. The Wadia 850 output stage can drive any power amplifier and any interconnects, even very long lengths. Does the Wadia Digital Volume Control compromise resolution? The Wadia 850 Compact Disc Player uses the latest generation of Wadia’s proprietary digital volume control. The volume level can be varied in the digital domain by means of mathematical manipulation of the signal, eliminating the distortion and noise that are inevitable with even the best analog volume controls. While conventional thinking indicates that reducing the volume digitally can sacrifice low level resolution, Wadia has created an innovative solution. Wadia’s patented digital filtering algorithm produces a 24 bit output rather than the 16 bits stored on the CD. This high-resolution signal is then used in the computations which in turn reduce the volume level. This new signal is fed directly to the DAC chips. Through this innovative method, the Wadia 850 maintains high resolution even at the lowest volume control settings. Can I bypass the Wadia Digital Volume Control? The Digital Volume control can be bypassed by setting the Volume Control to its maximum setting so that the front panel display shows a volume level of 99. The Wadia Digital Volume Control operates in the digital domain. It is a computer program which performs calculations on the numeric values from the CD recording. If the Volume Control is set to its maximum, 99 on the front panel display, this computer program is bypassed. What about Analog Sources? In order to fully realize the potential of this type of system, Wadia has introduced the Wadia 17 Analog-to-Digital converter. Now it is possible to use analog sources, such as a tuner, tape deck, or even a turntable (in conjunction with a suitable phono stage) in your system without using a conventional analog preamplifier. Consult your dealer for more information on the Wadia 17 and other future Wadia Analog-to-Digital products. Should I leave the Wadia 850 with the power on? The Wadia 850 is designed to be left with the power on with no harm or wear to the unit. All motors and laser circuitry turn off when the unit stops playing. If desired, the front display can be turned off (see Turning off the Display under Remote Operation). Leaving the power on allows the circuitry to remain in thermal stability, which provides better performance and longer life. Careful listeners will notice that the sound of the Wadia 850 will improve steadily after the unit is powered-up. A new unit will undergo more dramatic changes when power is applied for the first time. If you turn off your Wadia 850 for more than an hour, you will find that the unit will undergo similar, but less dramatic improvement once power is reapplied. Depending on the resolution of the system and the attentiveness of the listener, you may find that the sound continues to improve over the first several weeks of operation. Although there are many theories on why this occurs, none have been proven. However, years of listening experience has confirmed this phenomenon. 7 WADIA 850 COMPACT DISC PLAYER GENERAL OPERATION Turning on the Wadia 850 Using the switch located directly above the AC power input, turn the switch to the ON position.

Transport Programming Display f / Direct Access \ Enter i - Phase Invert INPUT 0O- Drawer Open /Close Input Select Pause Search * stop Play Volume - Track Forward /Rev A/B Repeat Repeat Single Track ’ ’ Transport Time Mode I Index 10 WADIA 850 COMPACT DISC PLAYER Adjusting the Volume Whenever the volume control keys are pressed, the volume for both channels will be increased or decreased by an increment of 1 on the display screen. The range of the volume control is from 1 to 99, with each step representing 0.5 dB change in volume. Selecting an Input (on units with optional digital inputs) The Wadia 850 Compact Disc Player has four digital inputs, plus the internal CD drive. Any of the inputs can be selected from the remote control by pressing the input key. Each time the input key is pressed, the next input is selected. For example, if you are listening to CD input and you press the input select, Input 1 will be selected, press it again, and Input 2 will be selected and so on. After Input 4, the list will begin again with the CD input. Inverting Absolute Phase The Wadia 850 has the ability to invert absolute phase in the digital domain. Pressing the Phase Invert key on the remote control will cause the Wadia 850 to invert phase; pressing it again will switch the phase back to normal. Phase is indicated with a green (normal phase) or red (inverted phase) LED display. Turning Display On/Off By pressing the Display On or Off key, the Wadia 850 display can be turned off completely. If the display is turned off, it will reappear briefly whenever a Wadia 850 function key on the remote control is pressed. Mute Modes The Wadia 850 Compact Disc Player has two mute modes that are automatically implemented under different circumstances. DSP-Software Mute When the Mute key is pressed on the remote control, the Wadia 850 Compact Disc Player’s DSP engine transmits a stream of zero signal level samples to the DAC section, which results in zero output. Output-Relay Mute The Wadia 850 Compact Disc Player has mute relay connected between the positive and negative outputs. When this relay is engaged, it connects the positive output to the negative output, reducing the output to zero. This relay, which produces an audible click when it engages or disengages, is not in the music signal path. The mute relay is engaged: 1. When the Wadia 850 Compact Disc Player detects AC input level below its minimum operating range. 2. Each time the Wadia 850 Compact Disc Player power switch is turned on. 3. When the volume control is set to zero AND the mute key on the remote control is pressed. When the Wadia 850 is in either Mute Mode, the Display will indicate this by displaying the word, “MUTE.” 11 COMPACT DISC PLAYER WADIA 850 REMOTE CONTROL OPERATION (continued) Pressing these buttons allows access to the previous or next index point within a track that has such indexed sections. TRACK FORWARD/REV: Pressing these buttons allows access to the previous or next track on a disc. SEARCH: Pressing these buttons allows fast reverse or fast forward access through a track. STOP: Pressing this button while a Compact Disc is playing stops PLAY. PAUSE: Pressing this button, while a Compact Disc is playing, suspends PLAY. Pressing the PLAY button will resume play at the point where the pause button was pressed. PLAY: After a Compact Disc has been loaded into the drawer, pressing this button plays the disc beginning with the first track on the disc or in a sequenced program. Pressing this button while the drawer is open, closes the drawer and begins play with the first track on the disc or in a sequenced program. PROGRAMMING THE CD TRANSPORT Program: Pressing this button enters all tracks subsequently chosen with the numeric keys (up to a total of 20 selections) as par-t of a programmed sequence. Programming a sequence of tracks can be done either in the stop mode or in the play mode. To program a sequence of tracks from a compact disc while in the stop mode, first press the program button. The program indicator will illuminate in the display window. Next, press the numeric buttons of the tracks you would like to program in the sequence desired. The number of each selected track will be indicated under the track indicator, the location of that track within the program (the playing order) of the tracks selected will be indicated in the area where index is usually identified, and the total program playback time of the sequence will be updated as each track is programmed. To program a sequence of tracks from a compact disc while in the play mode, the procedure is the same. The only difference is that the total program’s playback time will not be displayed. A program will continue to be held in memory, even after that program has been completely played. When programmed playback is ended by pressing the stop button, the program will continue to be held in memory. However, if the stop button is pressed a second time, the program indicator on the display will go out and the programmed contents will be erased from memory. 12 WADIA 850 COMPACT DISC PLAYER Single: To play a single track, press the single button (the single indicator will light in the display window), then press the numeric button(s) which correspond(s) to the track you would like to play. The transport will search for the selected track, and playback will start from the beginning of that track. At the conclusion of the track, the transport will enter the stop mode. To repeat one single track, press the single button (the single indicator will illuminate in the display window), then press the repeat indicator (the repeat button will illuminate in the display window), and then press the numeric button(s) which correspond(s) to the track you would like to repeat. Playback of the track selected will begin immediately. At the conclusion of the track the transport will return to the beginning of that track again, and in this way the selected track will be repeated. Delete: This button is the opposite of normal programming. Pressing this button while a program is being entered, erases the entire entered program. To play an entire disc, except for specific tracks that you do not want to hear, press this button and then the numeric keys corresponding the tracks you would like to delete (up to 20 selections). Clear: When the program indicator is illuminated in the display window. To eliminate a particular track from a programmed sequence, first press the check button until the track which you would like to eliminate is selected. Then press the clear button which will clear that particular track from memory. Time: This button switches between the various time modes on the display. Before play, the total time on the disc, or in a sequence program, is shown. Once a disc starts to play the elapsed time of that track will be shown. Pressing the button on the remote control once will cause the display to indicate the remaining time in that track (remain). Pressing this button on the remote control again will cause the display to indicate the remaining time on the entire disc, or in a sequenced program (total remain). Auto Space: Pressing this button will provide a four second space between tracks on disc, irrespective of the actual time between tracks on disc. Check: When a sequence of tracks has been programmed, the check button can be used to review the contents of that program. After a program has been entered, but before playback has begun, by pressing the check button once, the first programmed track number, its position in the sequence of tracks that have been programmed, and the playing time of the entire sequence, will be displayed. Each subsequent pressing of the check button will provide similar details as you move through each of the programmed tracks. The programmed contents of a sequence can also be checked during playback, however, the total program’s playback time will not be displayed. Repeat: Pressing this button will cause the entire disc to repeat continuously. Pressing this button a second time will take the transport out of the repeat mode. Pressing this button once, following pressing the single button, will cause the track that is playing, or has been selected, to repeat continuously. Pressing either the stop or open buttons will also take the transport out of the repeat mode. A/B: This button is used to define a section of a disc that is to be repeated continuously. Pressing this button once defines the beginning point (A) of the section to be repeated and pressing this button again defines the ending * ’ ’ point (B) of the section repeated. Pressing the button a third time will disengage the A/B procedure. 13 WADIA 850 COMPACT DISC PLAYER APPENDICES Troubleshooting Lock-up If the Wadia 850 experiences a powerful static shock or sudden AC surge, it is possible to “lock-up” the computer circuitry.
