Marshall Electronics' AR-AM4 features high fidelity speakers and DSP audio processing, with a variety of configurations.  This analog audio rack is ideal for TV facilities, studios, post production, VTR bays, mobile production vehicles, satellite links, and wherever audio monitoring is required.

The AR-AM4 is a 4-channel stereo analog audio monitoring system.  It features stereo loudspeakers in a compact 1RU form factor, with analog amplification and digital processing.  At only 6.0" deep, the AR-AM4 can be installed in many shallow rack cases or placed on any level surface.  This unit is enhanced with four balanced XLR inputs, along with a balanced XLR output for interfacing to downstream equipment.  Controls include separate headphone and speaker volume with master balance.  A powerful DSP-controlled EQ (coupled with a limiting compressor) provides unparalleled, pristine sound and speaker protection.
