Installation and Operation

System Operation
Receiver On
1. Turn down the AF level controls of the receiver.
2. Switch on the reciever. Power indicator will light up (red LED). AF peak
indicator (red LED) will brink and go off.
3. Turn off power switch of the transmitter(s) when changing the channels on
the reciver.
4. If the operation indicator(s) on the reciver light(s) up (yellow LED) when
your transmitter(s) is(are) off, there might be RF interference caused by TV
broadcast on or around the same frequency as your wireless system. Slide
the channel change switch(es) to other channel(s) to avoid the interference.
Be certain that the operation indicator(s) stay(s) off.
RF interference occur when radio signal or TV signal is on the same
frequency as the wireless microphone.
UniPak Input Level Adjustment
Trimmer adjustments in the UniPak transmitter (Fig. E) will enable you to use
microphones with different output levels or guitars that have built-in preamps.
To adjust microphone (Lo-Z) input levels, gently turn the “MT“ (Mic Trim-
mer) control to the full clockwise position (Hi). Check for excessive gain by
speaking/singing into the microphone at typically-loud levels while watching
the receiver’s AF Peak indicator. If the AF Peak indicator does light, turn the
MT control slightly counterclockwise until the AF Peak indicator no longer
lights with maximum audio input to the transmitter.
Follow the same procedure when using the guitar (Hi-Z) input, adjusting the
“GT“ (guitar trimmer) control to set the transmitter’s audio input level.
The input control not in use should be set to minimum.
CAUTION! The small trimmer controls are delicate, use only a small
screwdriver or alignment tool with a maximum 2mm-wide blade. Do not force
the trimmers beyond their normal 260º range of rotation.
Transmitter On
1. Select the same channel number with the channel switch on the transmitter
as selected on the receiver before switching on the transmitter (Fig. D).
Tuner A in the receiver is for the microphone transmitter with gold (silver)
band and tuner B for the one with red (blue) band. (in case of unipak
transmitter: refer to the frequency indication located on the bottom of
unipak transmitter.)
2. Set the switch on the microphone transmitter to “ON” position. Battery
indicator (red LED) will light. Replace the batteries if the battery indicator
doesn’t light.
3. Operation indicator (yellow LED) on the receiver will light. This shows that
the receiving signal is strong enough.
4. When changing the channel of a microphone transmitter, switch off the
transmitter first and then change the channel.
Receiver Squelch
The squelch control on the back of the receiver is preset at the factory, but
can be adjusted if you must use the system in an area with considerable
RF interference. Do not adjust the squelch control if not necessary.
Oversquelching the receiver may cause an unstable operation.

Introduction
Thank you for choosing an Audio-Technica professional wireless system.
You have joined thousands of other satisfied customers who have chosen
our products because of their quality, performance and reliability. This
Audio-Technica wireless microphone system is the successful result of years
of design and manufacturing experience.
The receiver is half-width for a standard 19” (1U) rack mount. Two receivers
(on different frequencies) can be mounted side by side, using an AT8628
joining plate kit.
Please note that in wireless-system applications there must be a
transmitter-receiver combination set to a separate frequency for each input
desired. Because some of the wireless frequencies are in or near UHF TV
frequencies, only certain wireless frequencies are usable in a particular
geographic area. Also, only certain of the available operating frequencies may
be used together.

Setup And Connection For Receiver
Setup:
1. For best operation the receiver should be at least 1m above the ground and
at least 1m away from a wall or metal surface to minimize reflections.
2. Keep the receiver’s antennas away
from noise sources such as motors,
automobiles, digital devices and neon
lights, as well as large metal objects.
3. Position the receiver so that it has the
fewest possible obstructions between it
and the normal location of the wireless
microphone. Line-of-sight is best.
4. When two transmitters are used simulta-
neously, keep the transmitters at least 2m away from the receiver,
meanwhile keep 2m at least between each transmitter.
Connection:
1. There are 2 kinds of audio outputs on the back of the receiver: balanced
(200 mV) and unbalanced (360 mV). Use shielded audio cable for the
connection between the receiver and the mixer. If the input of the mixer
is an XLR-type input, connect cables from the balanced XLR-type audio
outputs on the back of the receiver to the mixer. If the input of the mixer is
a 1/4” jack, connect cables from the 1/4” unbalanced audio outputs on the
back of the receiver to the mixer.
2. Attach the antennas to the antenna connectors on the front of the receiver.
3. Connect the included AC adapter to the DC power input on the back of the
receiver.
CAUTION! Electrical shock can result from removal of the receiver cover. Refer
servicing to qualified service personnel. No user-serviceable parts inside. Do not
expose to rain or moisture.
The circuits inside the receiver and transmitter have been precisely adjusted for
optimum performance and compliance with federal regulations. Do not attempt to open
the receiver or transmitter. To do so will void the warranty, and may cause improper
operation.

Notice to individuals with implanted cardiac pacemakers or AICD devicers:
Any source to RF (ratio frequency) energy may interfere with normal functioning of the implanted device. All wireless microphones have low-power transmitters (less than 0.05 watts output)
which are unlikely to cause difculty, especially if they are at least a few inches away. However, since a “body-pack” mic transmitter typically is placed against the body, we suggeat attaching
it at the belt, rather than in a shirt pocket where it may be immediately adjacent to the medical device. Note also that any medical-device disruption will cease when the RF transmitting
source is turned off. Please contact your physician or medical-device provider if you have any questions, or experience any problems with the use of this or any other RF equipment.

Nine Tips To Obtain The Best Results
1. Use only fresh alkaline batteries. Do not use “general purpose”
(carbon-zinc) batteries.
2. Position the receiver so that it has the fewest possible obstructions
between it and the normal location of the transmitter.
Line-of-sight is best.
3. The transmitter and the receiver should be as close together as
conveniently possible, but no closer together than one meter.
4. The receiver antennas should be in the open and away from any
metal.
5. The transmitter and receiver must be set to the same channel
number.
6. If the AF Level control of the receiver is set too high, it may
over-drive the input of the mixer or clip the output of the
receiver, causing distortion. Conversely, if the receiver output is
set too low, the overall signal-to-noise ratio of the system may be
reduced.
Adjust the output level of the receiver so the highest sound
pressure level going into the microphone causes no input overload
in the mixer, and yet permits the mixer level controls to operate in
their “normal“ range (not set too high or too low). This provides the
optimum signal-to-noise for the entire system.
7. You need to change channels 1) when a strong interference
signal is received, 2) when the channel breaks down, or 3) during
multiple-system operation in order to select an interference-free
channel.
8. In the UniPak transmitter, the “MT“ or “GT“ input control not in use
should be set to minimum.
9. Turn the transmitter off when not in use. Remove the battery if the
transmitter is not to be used for a period of time.
