Product Overview

The AR-AM4-BG is a 4-channel stereo analog audio monitoring system with DSP and Peak Meters. It features stereo
loudspeakers in a compact 1RU form factor, with analog amplification and digital processing. A front panel bi-color phase
indicator displays the phase relationship between the left and right channels. At only 6.0" deep, the AR-AM4-BG can be
installed in many shallow rack cases or placed on any level surface. This unit is enhanced with four pairs of balanced XLR
inputs, along with a balanced XLR output for interfacing to downstream equipment. Controls include separate headphone
and speaker volume with master balance and a front panel MUTE button. The unit's dual 10-segment bar graph meters
provide the ability to visually monitor the audio source. A powerful DSP-controlled EQ (coupled with a limiting compressor)
provides unparalleled, pristine sound and speaker protection.
