Thank you for purchasing AZDEN’S “PERFORMANCE SERIES” wireless system. UHF wireless
systems yield a better signal to noise ratio and improved frequency response over VHF systems. The
UHF hand is less crowded than VHF thus giving you less likelihood of interference. This manual covers
the 411UDR and 411DRl-l receivers and the SlBT, Sle and 41HT transmitters.
Receiver Descriptions: The 411UDR and 411DRH are crystal controlled, PLL synthesized receivers with 63
on-board user selectable frequencies with a range of 794M'l-lz to approx. 806M'Hzr They are true diversity,
containing two separate receivers, each operating on the same frequency. The transmitter’s output signal is
monitored constantly by a diversity circuit, which switches automatically to the receiver with the stronger RF
signa . This allows wireless performance that is virtually dropout free, even under the most adverse condi-
tinnsr Rnth receivers feature a I/A-inch and XIR output jacks and volume adjustment.
(1) Power LED and on/ofl' switch (41 IDRH only)
Alter plugging in the 411DRH. depress the on/off switch to turn unit on and illuminate the Power LED.
The 411DR’s Power LED will illuminate as soon as the unit is plugged in.
(2) Antenna A-B LED’s
When the transmitter is turned on and is in reception range of the receiver, either theA or B LED will light up
RED, depending on which receiver circuit is getting the strongest signal from the transmitter. Flickering
between the A and B LED is a normal function of the system
(3) Peak LED
These will flash if the audio component of the incoming signal is approaching distortion. The 411DRH has a 7
segment LED display to show the incoming audio signal from -20 to + 6 dB.
(4) Antennas, antenna connections
On both the 41 IUDR and 411DRH, position the antennas vertically for best reception. On the 411UDR, when
not in use put the antennas in the holder to avoid damage On the 411DRH the antennas are connector
mounted (BNC) so that the supplied antennas can be disconnected and/or removed.
(1)
(5) 12 Volt Input
Plug the supplied AC adapter into the 12 volt input on the receiver then into an AC electrical outlet Use only
the adapter supplied, as other adapters may damage the receiver.
(6) Output Adjustment
Rotate this knob clockwise to increase, or counterclockwise to decrease Volume level.
(7) Output (unbalanced)
Using a suitable audio cable (not supplied) connect the l/4-inch phone jack end to the audio output on the
receiver, and connect the other end of the cable to the suitable mic/line input of an audio mixer or amplifier.
(8) Output (balanced)
Using a suitable audio cable (not supplied) connect the XLR connector to the audio output on the receiver, and
connect the other end of the cable to the suitable midline input of an audio mixer or amplifier.
(9) & (10) Frequency select
The group knob (9) allows you to select any of seven trequency groups (numbered from 0-6) The channel
knob (10) allows you to select any of nine frequency channels (numbered 0-8) within the selected group. Any
receiver/transmitter pair must be on the same group and frequency to operate properly. Be sure that both the
transmitter and the receiver are OFF before selecting/changing the frequency.
When using more than one system, all receivers and transmitters must be set to the same group to avoid
intermodulatlon distortlon while all transmitter/recelver pair must be on different frequencies.
(ll) Rack ears
If you wish to use one or two 4] lDRHs in a standard 19" rack you must attach the rack ears (HR-l or HR-Z —
purchased separately) by attaching the ears with the four machine screws (two per side near front). The HR-2
also requires the attachment of ajoining plate underneath the two units.
(2)
The following feature is for the 41 lDRH only,
(12) Squeleh adjust
This adjusts the point at which the receiver will shut off or “squelch” the incoming radio signal when it
becomes too weak. Turning the control clockwise raises the threshold, allowing more signal to enter, and
turning the control counterclockwise lowers the threshold, letting in less signal.
When operating multiple systems all receivers and transmitters must be on the same group
Example: 4 systems operating simultaneously.

‘5-l le=c>
(4) 2 Position switch
The bottom position is “011” and the top position is “On”. Turning the transmitter Off will cause the receiver
to mute due to the tone squelch circuitry at the receiver. This allows the mic to be handled with no noise.
(5) LED Indicator turns green when armed on. This LED will also tum red to indicate that the battery level is
low and the batteries must be changed.
(6) The antenna attaches to the bottom of the microphone. It is screwed on clockwise and should be snug.
(4)
The SIBT body-pack transmitter has 63 user selectable UHF fi'equencies and is ideal for lavaliere and headset
microphones. The optional MP-lH instrument cable allows the 5 lBT to work with electric guitars and basses.
(1) Open the battery compartment lid by sliding it down and raising it.
(2) Insert one fresh alkaline 9-volt battery into the compartment Make sure battery polarity is correct.
(3) Frequency select:
The group knob (left) allows you to select any of seven frequency groups (numbered from 0-6). The channel
knob (right) allows you to select nine frequency channels (numbered 0-8) within the selected group. Use the
flat end of the provided tool to adjust these settings.
(4) Audio input Level Control:
Enables you to adjust the input level of the microphone or musical instrument. Tum clockwise to increase, or
counterclockwise to decrease the input level. Use the + end of the provided tool to adjust this setting The
level control is factory-preset in the center position.
(5) Power and standby switches:
The power “On” and “on" switch enables and disables all transmitter functions while the audio switch “On”
and “Standby“ turn the audio off and on. Switching the transmitter to “Standby" will cause the receiver to
mute using the tone squelch circuitry in the receiver. This allows the microphone to be handled with no noise.
(6) LED Indicator:
Tums green when the transmitter is turned on This LED will also tum red to indicate that battery level is low
and the battery must be changed.

allows you to select any of nine frequency channels (numbered fi'om 0-8) within the selected goup.
(4) Power and Audio switches
The power “On/Off" switch enables and disables all transmitter functions while the Audio “On/oft" switch
turns just the transmitter's Audio signal on and off. Switching the Audio to “Off“ will cause the receiver to
mute using the tone squelch circuitry in the receiver. This allows the microphone to be handled with no noise.
The “Phantom" switch allows the 5 lXT to provide 5V to power electret condenser microphones.
(5) Audio input LEVEL control
This enables you to adjust the input level of the microphone. Turn clockwise to increase. or counterclockwise
to decrease the input level. A small screwdriver is supplied to make adjustments.
(6)
(6) LED INDICATORS
The POWER LED turns green when power is turned “On” or red if battery level is low. If this LED lights up
red replace the battery.
The AF PEAK LED lights up if the input level is set to high, indicating the onset of distortion, Lower the
input level so that the AF PEAK LED lights only occasionally.
To plug the Sle onto a microphone (low impedance with XRL connector) first make certain the locking-ring
is tumed fully up (rotate counterclockwise). Then plug the 51XT fully into the microphones XLR connector
and tighten by rotating the ring fully down (clockwise),
OPERATING THE SYSTEM:
Because this a frequency agile system, meaning that you choose the frequency of both the transmitter and
receiver via the group and channel controls, we cannot stress enough that any transmitter/receiver pair that you
want to transmit and receive on MUST BE SET TO THE SAME FREQUENCY!
Additionally, multiple systems used in the same proximity must ALL BE ON THE SAME GROUP SELEC-
TION! To change the frequency that a transmitter/receiver pair is already on YOU MUST TURN OFF BOTH
TRANSMITTER AND RECEIVER FIRST!
Do not place the receiver on a metal surface, and avoid obstructions between the receiver and transmitter,
since this could degrade the performance of the equipment.
First, make sure that the power to all your components is turned off. Connect an audio cable from the output of
the receiver (phone jack or XLR) to a mic/line input on your audio mixer or amplifier, Plug the receiver‘s AC
adapter into the 12V input jack on the receiver and then plug it into the AC electrical outlet. With the volume
of your mixer or amplifier set to minimum level, turn ytmr system’s power on Turn on the transmitters)
Make sure all LEDs on the receiver(s) and transmitter(s) are operating as described in the preceding pages,
Now set the receivers volume to the midway point and adjust the Volume level on your mixer or amplifier.
(7)
' 5 lBT with Lavalieie or Headset:
With someone talking into the microphone, turn the volume on the mixer or amplifier to the desired level. If
there is too much, or not enough gain, lower or raise the volume on the receiver. if the sound is distorted,
lower the input gain on the transmitter.
SlBT with Instrument cable for electric guitars or basses (MP-iii):
Ping the cable into the guitar or bass. Set the instrument volume to the midway point. While playing the
instrument, turn the volume on the mixer or amplifier to the desired level. if there is too much, or not enough
gain, lower or raise the volume on the receiver. If the sound is distorted, lower the input gain (4) on the
transmitter.
51XT: With someone talking into the microphone, turn the volume on the mixer or amplifier to the desired
level. If there is too much, or not enough gain, lower or raise the volume on the receiver. If the sound is
distorted, lower the input gain on the transmitter.
4 lHT:
With someone talkingsinging into the microphone, turn the volume on the mixer/amplifier to the desired
level. If there is too much, or too little gain adjust the volume on the receiver. If the sound is distorted, move
the microphone further away from the sound source Make sure that the LED is green when the mic/transmit-
ter is turned On. When the battery is low, the LED turns red indicating that the battery needs to he changed.
NOTES:
- All “Performance Series” transmitters will work continuously for approximately es hours using an
alkaline battery. _
- Remove the battery if the transmitter will not be used {or a long period of time.
- Do not use or store the system in areas of high temperatures or humidity.
- Do not use this system near a broadcast station, airport, or airplanes, it may cause interference If you
are interfering with other transmissions you must turn off the system.
- These systems contain no user serviceable parts. If unauthorized service is performed it may void the
warranty.
