choice. Use only copper-shielded cable, not CATV-type foil-shielded wire. Audio-Technica offers auxiliary
antennas, and quality RF cables in four lengths.
Antenna Power
The antenna input jacks also can provide +12V DC output on their center pins to power inline RF devices.
A maximum of 20 mA can be drawn from each of the jacks. While an accidental short-circuit will not harm
the internal 12V supply, make certain that an antenna cable shield does not contact the center
conductor. Antenna Power (“ANT.PWR”) is selected (switched on or off) from the LCD menu. (On the
AEW-R5200, Antenna Power will be found in the menu on Channel 1 only.)

Receiver Installation (Continued)
Front-mount Antennas
AEW-R4100: Provision has been made to move the antenna jacks from the rear to the front of the
receiver. However, because this involves opening the receiver case and exposing AC power circuitry,
instructions are not included in this manual. A qualified service technician must perform this
modification.
AEW-R5200: BNC-to-BNC connectors and jumper cables are included with the unit to permit mounting
antennas on the front panel.
BNC-BNC through-panel connectors: Remove the nut and lock-washer from each connector.
Install the connectors from the front into the two panel holes. Note that the flat on the threaded
section must be aligned with the flat in each panel hole. Secure each connector from the back
with its lock-washer and nut, tightening the nut firmly.
BNC-BNC cable jumpers: Connect the jumpers to the rear antenna jacks first; then attach them to
the BNC connectors on the front panel. Make certain the bayonet twist-rings are fully latched on
the connectors at both ends.
Headphone Jack
A headphone jack on the front panel provides monitoring of the receiver’s output. The 1/4" TRS jack is
intended for use with stereo headphones. The Phones Level control affects the headphone jack only.
Note: On an operating unit, be careful not to press the Power switch accidentally when inserting a
headphone jack or adjusting the headphone level. In addition to interrupting receiver operation, even a
momentary loss of power to a single unit within a linked multi-channel system will cause the loss of
linking connection to the affected receiver and all those “downstream” from it.
AEW-R5200: Press and release the Phones Level control knob to switch headphone monitoring from
Channel 1 to Channel 2 and back again. Small, lighted indicators just above the knob show which receiver
channel is being monitored.
