A. Remove packing material

B. Install the AWR6951 receiver

1. Place the AWR6951 receiver at a location at least 3.5 feet (1 meter) away

from the ground and all the walls. Also, keep the AWR6951 receiver

away from any electro-magnetic noise sources as far as possible.

2. Mount both the antennas onto the left and right BNC antenna jacks. Make

sure that any of the antennas is not enclosed in a large metal body.

3. There are two options of power supplies for the AWR6951 receiver. The

first option is to use the supplied 12VDC adaptor. The second option is to

use eight (8) AA batteries (not included) which are to be placed into the

AA-battery-power-supply battery compartment (refer to numeral 15 on

pages 6 and 8).

(a) If the first option is selected, plug the supplied AC/DC adaptor 12VDC

output connector to the AWR6951 receiver's DC input, and then plug

the AC input of the adaptor to a 120V AC outlet (North America).

(b) If the second option is selected, place eight (8) AA batteries into the

AA-battery-power-supply battery compartment.

4. Connect the outputs of the AWR6951 receiver to microphone inputs of a

mixer or a sound system. In order to do so, (1) you could use the

supplied microphone cable (a cable with ¼” connectors on both ends) to

connect from the unbalanced output (an ¼” jack) to an ¼” microphone

input on a mixer or a sound system; or (2) you could get two balanced

microphone cables (cables with a male XLR connector at one end and a

female XLR connector on the other end; not included) to connect from

both the balanced outputs (male XLR jacks) to two XLR microphone

inputs on a mixer or a sound system.

5. When the ¼” output on the rear panel of the AWR6951 receiver is

connected to an AUX-IN of a mixer or a guitar input, set the H/L switch to

“H”. Otherwise, set the H/L switch to “L”. The XLR balanced outputs

on the rear panel of the AWR6951 receiver are to be connected to

microphone inputs only.

6. The AUX audio output jack on the rear panel is a 3.5mmTRS (stereo) jack

with a mono sound signal (meaning the tip, T, and the ring, R, of the

stereo jack carrying the identical sound signal). This AUX audio output

can be connected to a 3.5mm AUX-IN of a mixer or sound system through

the supplied 3.5mm cable or any cable with 3.5mm TRS (stereo)

connectors on both ends.

QUICK SETUP

7. Turn both audio level adjustment knobs all the way to the minimal audio

position. (Note: The audio level adjustment knobs will be adjusted to its

optimal position after the transmitters are turned on as discussed in the

following section.)

If the supplied 12VDC adapter is to be used as the power source, turn the

On/Off switch to the upper position (position I). After the power On/Off

switch is turned to the upper position, the blue 12VDC power LED

indicator (refer to numeral 2 on pages 6 and 7) will be turned on.

If the AA-battery power is to be used as the power source, turn the power

On/Off switch to the lower position (position II). After the power On/Off

switch is turned to the lower position, the red AA-battery-power-supply

LED indicator (refer to numeral 3 on pages 6 and 7) will be turned on.

After the AWR6951 receiver is turned on, the LCD on the front panel will

display the current receiver state.

C. Set up the transmitters

(a) Set up the handheld transmitter

1. Open the battery cover (refer to numeral 20 on pages 8 and 9) of the

handheld transmitter by firmly pushing the battery cover to the direction

away from the microphone windscreen (refer to numeral 16 on page 8).

2. Place two 1.5V AA batteries into the battery housing with the battery

polarity orientations as indicated.

3. Push the battery cover in the direction toward the microphone

windscreen until it clicks to close the battery cover.

4. Turn on the power of the handheld transmitter by push the On/Off switch

in the direction toward the microphone windscreen. The green LED

indicator will blink once and stay off (If the green LED light stays on, the

AA batteries need to be replaced).

(b) Set up the body-pack transmitter

1. Open the battery cover of the body-pack transmitter by pushing the latch

button (refer to numerals 32 & 33 on pages 9 and 10) inwards (There is a

concaved opening and the latch button is at the lower side of the

opening) and flipping open the battery cover.

polarity orientations as indicated.

-4-

3. Flip the cover down in the direction toward the latch button to close the

battery cover. Plug the supplied headset or lavalier microphone into the

microphone input (a mini XLR jack) on the body-pack transmitter. When

the lavalier microphone is used, the AUDIO INPUT ATTENUATION

SWITCH (refer to numeral 31 on pages 9 and 10) needs to be set to the

0dB position. When the headset microphone is used, the AUDIO INPUT

ATTENUATION SWITCH needs to be set to the -10dB position.

4. Turn on the power of the body-pack transmitter. The green LED indicator

will be turned on.

D. Setting up the AWM6951 system
