It may overheat, possibly causing damage. 4 Never open the cabinet. If a foreign object drops into the set, contact your dealer. 5 Do not place records or other objects on top of the unit; this will block the ventilation holes, cause the internal temperature to rise and may result in a failure. 6 Do not use force on switches, knobs or cords. When moving the set, first turn the unit off. Then gently disconnect the power plug and the cords connecting to other equipment. Never pull the cord itself. 7 Do not attempt to clean the unit with chemical solvents; this might damage the finish. Use a clean, dry cloth. 8 To prevent lightning damage, pull out the power cord and remove the antenna cable during an electrical storm. 9 When not planning to use this unit for long periods of time (ie., vacation, etc.), disconnect the AC power plug from the wall outlet. 10 Be sure to read the “Troubleshooting” section on common operating errors before concluding that your unit is faulty. We Want You Listening For A Lifetime YAMAHA and the Electronic Industries Association’s Consumer Electronics Group want you to get the most out of your equipment by playing it at a safe level. One that lets the sound come through loud and clear without annoying blaring or distortion – and, most importantly, without affecting your sensitive hearing. Since hearing damage from loud sounds is often undetectable until it is too late, YAMAHA and the Electronic Industries Association’s Consumer Electronics Group recommend you to avoid prolonged exposure from excessive volume levels.

When making connections between this unit and other components, be sure all connections are made correctly, that is to say L (left) to L, R (right) to R, “+” to “+” and “–” to “–”. Also, refer to the owner’s manual for each component to be connected to this unit.

If the connections are faulty, no sound will be heard from the speakers. Make sure that the polarity of the speaker wires is correct, that is, + and – markings are observed. If these wires are reversed, the sound will be unnatural and will lack bass. How to Connect: Red: positive (+) Black: negative (–) ● ● ● One or two speaker systems can be connected to this unit. If you connect only one speaker system, connect it to either the SPEAKERS A or B terminals. Use speakers with the specified impedance shown on the rear of this unit. Banana Plug connections are also possible (except for Scandinavian models). Simply insert the Banana Plug connector into the corresponding terminal. *When connecting Banana Plugs to this unit’s SPEAKERS terminals, be sure to tighten the terminal knobs to make contact securely before connections. ➁ ➀ Unscrew the knob. ➁ Insert the bare wire. ➂ Tighten the knob and secure the wire. ➂ ➀ Caution When inserting the stripped ends of the speaker wires as shown above, make sure at least 1/16 inch (1.6 mm) of insulation is inside the wire holders (i.e. no exposed wire is visible) and no loose conductor wire strands are protruding after connection. If wires touch each other or they touch the metal parts of this unit, this unit and/or speakers could be damaged. To prevent speaker wires from coming loose, make sure wire holders are firmly screwed in. REMOTE CONTROL (PRE AMP) connector If you have the YAMAHA pre-amplifier CX-1 or CX-2, connect this connector to the REMOTE CONTROL (POWER AMP) connector of the pre-amplifier by using the cable provided with the pre-amplifier. By this connection, the power of this unit is controlled by the pre-amplifier’s POWER switch or the POWER key of the remote control transmitter provided with the preamplifier. After the connection is completed, keep the POWER switch of this unit pressed inward (to the ON position). Note If you will not connect the REMOTE CONTROL connectors of this unit and the pre-amplifier, do not connect the cable to either connector. Otherwise, this unit will not function normally. REMOTE CONTROL ( PRE AMP ) 5 CONTROL PARTS AND THEIR FUNCTIONS FRONT PANEL ➊ SPEAKERS ➋ REAR PANEL ➌ ➌ LEVEL LEVEL INPUT REMOTE CONTROL ( PRE AMP ) REMOTE CONTROL ( PRE AMP ) INPUT ➊ POWER switch/indicator (POWER) Press this switch to switch ON the power. The indicator will illuminate while the power is ON. Press the switch again to switch OFF the power. Note the following cautions. ● Before switching ON the power, be sure to set the volume control of the pre-amplifier to the lowest setting in order to avoid damage to the speakers. ● The speaker-protection circuit functions to mute speaker sound reproduction for a few seconds after the power is switched ON. STANDBY mode (For Europe model only) If the REMOTE CONTROL (PRE AMP) connector on the rear panel of this unit is connected to the corresponding connector of the pre-amplifier (CX-1 or CX-2), by turning the power off with the POWER switch of the pre-amplifier, this unit is switched to the STANDBY mode. (In this mode, the indicator over the POWER switch is half illuminated.) 6 ➋ SPEAKERS switches Because one or two speaker systems can be connected to this unit, these switches allow you to select speaker system A or B, or both at once. ➌ Input level controls (LEVEL) These controls adjust the level of signals input to this unit. Normally set these controls to the “10” (maximum) position, and adjust the whole sound output level with the VOLUME control of the pre-amplifier. However, if your speakers’ permissible music input power is not high enough or sounds from the speakers are distorted, turn these controls counterclockwise to decrease the level. Note To turn the power off completely, disconnect the AC power plug from the wall outlet. TROUBLESHOOTING If the unit fails to operate normally, check the following points to determine whether the fault can be corrected by the simple measures suggested. If it cannot be corrected, or if the fault is not listed in the SYMPTOM column, disconnect the power cord and contact your authorized YAMAHA dealer or service center for help. SYMPTOM CAUSE REMEDY The unit fails to turn on when the POWER switch is pressed. Power cord is not plugged in or is not completely inserted. Firmly plug in the power cord. No sound. The SPEAKERS switches are released outward to the “OFF” position. Press them inward to the “ON” position. The speaker level controls are set to the fully counterclockwise position. Turn them clockwise. Connection cords are not connected securely to the INPUT terminals. Connect them securely. Speaker systems are not properly connected to this unit. Connect them correctly. The sound suddenly goes off. The protection circuit has activated because of short circuit etc. Turning the unit off and then on will reset the protection circuit. No sound is heard from the left and/or right speaker systems. Speaker systems are not properly connected to this unit. Connect them correctly. The input level controls are set to the fully counterclockwise position. Turn the input level controls clockwise. The acoustic “image” is unstable, characterized by unnatural sound and insufficient low-range tonal quality. The positive (+) and negative (–) polarities (of this unit and the speaker systems) are not matched. Reconnect the speaker systems to this unit so that the polarities are aligned. Hum noise is heard from the speakers. Connection cords are not connected securely to the INPUT terminals. Connect them securely. 7 SPECIFICATIONS Minimum RMS Output Power per Channel 8 ohms, 20 Hz to 20 kHz, 0.008% THD ..............200W+200W 4 ohms, 20 Hz to 20 kHz, 0.03% THD ................260W+260W 2 ohms, 20 Hz to 20 kHz, 0.09% THD ................320W+320W 8 ohms, 20 Hz to 20 kHz, 0.008% THD ..............150W+150W 4 ohms, 20 Hz to 20 kHz, 0.03% THD ................190W+190W 2 ohms, 20 Hz to 20 kHz, 0.09% THD ................230W+230W Dynamic Power per Channel (by IHF Dynamic Headroom measuring method) 8/4/2 ohms .....................................................280/460/630W 8/4/2 ohms .....................................................190/310/410W DIN Standard Output Power per Channel (4 ohms, 1 kHz, 0.5% THD) [Europe model only] ......................................................................300W ......................................................................210W Dynamic Headroom 8/4/2 ohms ................................................1.46/2.48/2.94 dB 8/4/2 ohms ................................................1.03/2.12/2.51 dB IEC Power (8 ohms, 1 kHz, 0.01% THD) [Europe model only] ......................................................................225W ......................................................................175W Power Band Width 8 ohms, 100W, 0.03% THD .........................10 Hz to 60 kHz 8 ohms, 75W, 0.03% THD ...........................10 Hz to 60 kHz Damping Factor 8 ohms, 1 kHz ......................................................250 or more 8 ohms, 20 Hz–20 kHz (When using the SPEAKERS A terminals) ........350 or more Input Sensitivity/Impedance MAIN IN ....................................................1.46V/20 k-ohms ....................................................1.26V/20 k-ohms Frequency Response (20 Hz to 20 kHz) MAIN IN.....................................................................0±0.5 dB Signal-to-Noise Ratio (IHF-A Network) MAIN IN (Input Shorted) ................................................................... 125 dB ................................................................... 123 dB Residual Noise (IHF-A Network) ......................................20 µV Channel Separation (Vol. –30 dB) MAIN IN (Input 5.1 k-ohms Terminated 1 kHz/10 kHz) ...........................................................................80 dB/60 dB Power Supply [U.S.A. and Canada models] .......................AC 120V, 60 Hz [Australia and U.K. models] .........................AC 240V, 50 Hz [Europe model] ............................................AC 230V, 50 Hz [General model] .................AC 110/120/220/240V, 50/60 Hz Power Consumption [U.S.A. and Canada models]..........................560 VA, 420W [Australia, U.K. and General models]...........................440W [Europe model].............................................................550W [U.S.A. and Canada models]..........................440 VA, 340W [Australia, U.K., Europe and General models] .............360W Maximum Power Consumption (10% THD) [General model only] ....................................................................1950W ....................................................................1600W Dimensions (W x H x D) ............................486 x 116 x 438 mm (19-1/8” x 4-9/16” x 17-1/14”) Weight .............................................24.0 kg (52 lbs. 13 oz.) .............................................19.5 kg (42 lbs. 14 oz.)
