Receiver Installation

Location

For best operation the receiver should be at least 1 m above the ground and at least 1 m away from a wall or metal surface to minimise reflections. The transmitter should be at least 1 m from the receiver, as shown in Figure A.

Keep antennas away from noise sources such as digital equip- ment, motors, automobiles and neon lights, as well as large metal objects.

Output Connections

There are two audio outputs on the back panel: balanced

(32 mV) and unbalanced (52 mV). Use shielded audio cable for the connection between the receiver and the mixer. If the input of the mixer is a 1/4" jack, connect a cable from the 1/4" unbal- anced audio output on the back of the receiver housing

to the mixer. If the input of the mixer is an XLR-type input, con- nect a cable from the balanced XLR-type audio output on the back panel to the mixer. The two isolated audio outputs permit simultaneous feeds to both unbalanced and balanced inputs. For example, both a guitar amp and a mixer can be

driven by the receiver.

Antennas

Attach the included pair of UHF antennas to the antenna input jacks. The antennas are normally positioned in the shape of a “V” (both 45° from vertical) for best reception.

Antennas can be remotely located from the receiver. However, due to signal loss in cables at UHF frequencies, use the lowest-loss RF cables practical for any cable runs over 25 feet (8 m ). RG8-type is a good choice. Use only copper-shielded cable, not CATV-type foil-shielded wire. Audio-Technica offers quality RF cables in four lengths, as well as remote antennas; see the Optional System Accessories section on page 9.

Power Connections

Connect the supplied AT 220 ~ 240V, 50Hz AC adapter to the DC power input on the back of the receiver. Operation of the receiver is controlled by the front-panel Power switch.
