QUICK SETUP

A. Remove packing material

B. Install the AWR6952U receiver

1.

Place the AWR6952U receiver at a location at least 3.5 feet (1 meter) away from the ground and all the walls. Also, keep the AWR6952U receiver away from any electro-magnetic noise sources as far as possible.

2.

Mount both the antennas onto the left and right TNC 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 AWR6952U 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 18 on pages 7 and 9).

(a) If the first option is selected, plug the supplied AC/DC adaptor 12VDC output connector to the AWR6952U 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 AWR6952U 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 AWR6952U 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 AWR6952U 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.

2. In the main menu, press the “▲” or “▼” button to the “Sync” icon.

3. After the “Sync” icon is displayed, press the “SET” button and “NO” will be displayed.

4. Then press the “▲” or “▼” button to toggle the display between “YES” or

“NO”.

5. If it is desired to have the frequency of the AWX6952U transmitter be set to the same as that of the AWR6952U receiver, press the “▲” or “▼” button to have the “YES” display.

6. When “YES” is displayed, press the “SET” button to prepare to set the transmitter frequency as follows:

-16-

As shown in the above diagram, align the IR window of the AWX6952U to the IR window of the AWR6952U with a distance of less than four inches

(10cm). The LCD screen will display “IR >>>”. When the frequency of the

AWX6952U is successfully set, the AWR6952U will return to the main menu. Otherwise, the LCD screen will display “END”. When the “END” is displayed, press any button to return to the main menu.

NOTE: When “NO” is displayed, the AWR6952U will exit to the main menu without any further action. Press the “POWER ON/OFF” button at any time, the AWR6952U will exit to the main menu without saving any setting.

SETTING UP & DEBUGGING

1. After the AWM6952U system has been set up, keep both AWX6952U transmitters powered off and turn both volume control knobs on the

AWR6952U receiver all the way to the minimum. Turn on the power of the

AWR6952U receiver. Both LCD screens will display the settings of the previous set-up.

2. On the AWR6952U, tune both channels to have desired frequencies with manual tuning or the auto scan (preferably auto scan). Adjust both channels to have the SQ level of 5 dB and, then, return to the main menu.

At this stage, both transmitters are still off. If the radio frequency (RF) signal level indicator shows an incoming RF signal received by the

AWR6952U receiver, there is an intermittent interference signal to the receiver. Either adjust the SQ level higher (higher dB number) or change the frequency with manual tuning or auto scan again. Repeat this process until the RF signal is clear.

3. Turn on both transmitters. After the built-in CPU completes initialization, check if the frequencies of both transmitters are the same as the frequencies of both channels of the receiver. If any transmitter has different frequency from that of the receiver, refer to the

SYNCHRONOUS FREQUENCY MATCHING section (on page 16 ) to synchronize the transmitter frequency to the receiver frequency. Once the frequencies for both transmitters are matched to the frequencies of the receiver, adjust the volume control for each channel and the

AWM6952U is ready to be used.

OPERATION NOTES

1. The AWX6952U, AWX6952UG, AWX6952UH, and AWX6952UM need to be turned off before changing the AA batteries.

2. Signal dropout or unexpected noise may be caused by a low battery or by an excessive distance between the transmitter and the receiver. If you encounter signal dropout or unexpected noise, please check the batteries first. If the batteries are still fresh, try to readjust the antennas on the AWR6952U receiver.

3. Avoid placing the receiver in a corner to prevent any RF reception deterioration.

4. Avoid placing the receiver antennas close to an obstruction or close to any metal surface.

5. Try to place the receiver as far away from the digital equipment, including computers and CD players, as possible.

6. If more than one AWR6952U wireless microphone systems are stacked together or placed in a rack, do not let the antennas touch each other or cross each other.

7. Before the AWM6952U is to be used in a new location, place the

AWR6952U receiver at the intended location and walk through the area with the transmitters to locate any radio frequency blind spots, where a momentary loss of sound or short period of noise may occur whenever the transmitters are moved to these spots.

8. Do not drop the transmitter on the floor or strike the transmitter with any object.

9. Always turn off the transmitter and remove the batteries if the transmitter is not to be used for a period of time to prevent the transmitter from being damaged by leaking batteries.
