Audio-Technica ATW-A62P, ATW-A72P manual Setting Gain, Specifications, Cable Connections

Cable Connections

Refer to Figure F (cable rear exit) or Figure G (bottom exit) for connecting positions. When using a screwdriver on the antenna terminals, always support the PC board.

Center Conductor: Wrap the center conductor(s) clockwise around its screw and tighten snugly. (If using RG8, it is good practice to bend its center conductors using pliers, not force them around the screw terminal.)

Shield: It’s most effective to remove the cable clamp entirely, properly position the shield portion of the cable, and then care- fully reinstall the cable clamp over the shield. Make certain that the shield (and cable) are firmly clamped, and that no shield wires are loose or touching the center conductor.

Especially when using RG8 or other large, stiff cable, it’s a good idea to provide some form of clamping of the cable near the antenna’s cable entrance for strain relief.

Setting Gain

The gain switch on the PC board is intended only to compen- sate for signal lost in the antenna cable. Using "extra" gain is not necessarily better! Observe the following chart for proper gain switch setting:

Gain Setting		RG58-Type Cable	RG8-Type Cable
Hi (+10 dB)		20-50' (6-15 m)	50-150' (15-50 m)
Mid	(+4 dB)	Up to 20' (6 m)	Up to 50' (15 m)
Lo	(–2 dB)	This setting may work best when
		many channels are in use in the room,
		or when external RF noise is a problem.

Both antennas in a diversity system should be set to the same gain position. Other than setting the gain switches, do not make any adjustments to the circuitry.

After stripping the cables, making cable connections and setting gain, replace the antenna housings. When re-installing the hous- ing, be careful to avoid hitting the clear plastic "light pipe" for the LED power indicator. Once the housings are secured with the silver screws, connect the antenna cables to the diversity receiver or antenna distribution system and turn on the system. Then check for power indications at the antennas and proper operation of the overall wireless system.
