Frequently Asked Questions - ATW-49CB Audio-Technica

How do I connect the ATW-49CB receiver to a mixer?

Use an XLR cable from the balanced output on the receiver to a mic input on your mixer. You can also use a 1/4" TS cable from the unbalanced output if needed.

Can I use multiple receivers together?

Yes, you can set each receiver to a different frequency within the UHF band. Ensure frequencies are compatible to avoid interference.

What is the range of the ATW-49CB receiver?

Under typical conditions, the operating range is up to 100 meters (330 feet) line of sight.

How do I change the frequency on the receiver?

Press the SET button on the front panel to enter frequency mode, then use the UP/DOWN buttons to select a channel. Press SET again to confirm.

Why is my receiver not receiving any signal?

Check that the transmitter is on and set to the same frequency as the receiver. Ensure antennas are connected and that there is no obstruction. Adjust squelch if necessary.

Can I rack-mount the ATW-49CB?

Yes, it is designed for rack mounting. An optional rack-mount kit (sold separately) allows you to mount one or two units side by side.

What type of power adapter does the receiver need?

It requires a 12-18 V DC, 500 mA adapter with a center-positive plug. Only use the supplied adapter to avoid damage.

How do I clean the receiver?

Use a soft, dry cloth to wipe the exterior. Do not use any harsh chemicals or solvents. Keep the ventilation grilles clear of dust.

Is the ATW-49CB compatible with other Audio-Technica transmitters?

Yes, it is compatible with ATW-49 series transmitters such as the ATW-49BT bodypack and ATW-49HT handheld microphone.

What should I do if the receiver stops working?

Check all connections and power supply. If problems persist, contact Audio-Technica customer support for troubleshooting or repair. Do not attempt to open the unit.

ACTIVE ANTENNA COMBINER KIT

Two audio equipment modules with attached coaxial connectors (no visible text or symbols)

The Audio-Technica ATW-49CB Active Antenna Combiner Kit includes two dual-input, one-output Active Antenna Combiners designed for use with Audio-Technica 4000 and 5000 Series UHF wireless receivers and ATW-A49 LPDA antennas.* Each Active Antenna Combiner is a broadband device (frequency range from 440 to 900 MHz) that combines two incoming RF signals into one outgoing RF signal. One set of Active Antenna Combiners enables two sets of antennas to feed one wireless receiver or distribution system. To compensate for RF signal loss associated with combining signals, the Active Antenna Combiner provides unity gain. (Note that without the use of an antenna preamplifier, long antenna-cable length may deteriorate signal.)

Each kit includes: two Active Antenna Combiners and two 45mm BNC-to-BNC RG 58 coaxial antenna cables.

NOTE: The ATW-49CB Antenna Combiner requires +12V DC power from any Audio-Technica 4000 or 5000 Series receiver or +5 to +14V DC from any wireless receiver or antenna distribution system that offers antenna power. A light on each Active Antenna Combiner indicates that power has been correctly applied.

* The ATW-49CB Active Antenna Combiner Kit is also suitable for use with other receivers that are in its specified band, use BNC antenna connectors, and provide antenna terminal voltage; it may also be used with a variety of other antennas from Audio-Technica and other manufacturers.

HOW TO INSTALL THE ATW-49CB ACTIVE ANTENNA COMBINERS

1. Connect one BNC-to-BNC RG 58 coaxial antenna cable (two supplied) to the OUT connector on one Active Antenna Combiner (two supplied). Connect the other end of this cable to the ANTENNA A input on either a receiver or distribution amplifier, as shown in Figure 1.
2. Repeat step 1 for the ANTENNA B input, using the second Active Antenna Combiner.
3. Use coaxial antenna cables (not included) to connect the IN connectors on each Active Antenna Combiner to a UHF antenna, as shown in Figure 1.
4. NOTE: ATW-A49 antennas do not require power. If you are using ATW-A49 antennas, skip Step 4. If you have an antenna system that requires power (such as an antenna preamp or booster) you must open the ATW-49CB Active Antenna Combiner assembly and activate a switch on the circuit board. (This enables the combiner to pass power through to the antenna.) Current consumption of the preamp or booster should not exceed 100mA.

The unit is shipped with the switch in the "off" position. To flip the switch to the "on" position, first be certain the combiner is not attached to any power source. Next, use a Phillips screwdriver to remove the two screws on the Active Antenna Combiner's access panel; remove the access panel; use a tweezers to flip the switch into the "on" position. Finally, replace the access panel and securely tighten the two screws. (See Figure 2.)
