(This page intentionally left blank) Figure 2 – AR900-32 Receiver (Rear Panel) Connecting Power to the Transmitter and Receiver The AT900-32 and the AR900-32 each require an external power source of between 7.5 and 18 volts DC. A plug-in 120VAC-to-9VDC power converter is supplied with each unit. Insert the power converter’s 2.1mm plug into the DC INPUT jack on the unit’s rear panel (refer to Figures 1 and 2). Plug each converter into a live 120VAC outlet.

Noise Reduction (Transmitter and Receiver) The transmitter and receiver are each equipped with active noise reduction circuits. However, these circuits are normally turned off (factory preset), to provide the widest possible frequency response for high fidelity music listening.

Setting the Transmitter’s Audio Modulation Level With an active audio source connected to the transmitter’s AUDIO INPUTS, adjust the AUDIO LEVEL control on the front panel such that the green MODULATION LEVEL OK indicator is illuminated whenever audio is present, and the red PEAK indicator flashes only on the loudest audio transients. To prevent distorted audio at the receiver, the red PEAK indicator should not be illuminated continuously.

Internal Settings The AT900-32 transmitter and the AR900-32 receiver each have internal jumpers and/or switches (on their respective printed circuit boards) that are preset at the factory to provide the proper configuration for most applications. The following sections describe these settings, and provide guidelines for when it may be necessary or desirable to modify them.
