The RM-3 Rackmount 20W Speaker System from Fostex is designed to fit the monitoring needs of space-challenged environments like machine rooms, surveillance operations, and mobile or stationary control rooms. The unit accepts both digital and analog source inputs for compatibility with a wide range of systems, while featuring a THRU output that allows you to send the audio to another destination. Dual anti-magnetic cone speakers provide playback, with the option of using the headphone jack for quiet monitoring.

Left and right channel 26-dot LED meters give you a visual representation of your levels. A mute switch can be programmed for total mute, or to provide a 20 dB attenuation based on your preference.

Rack mount stereo monitor speaker system with built-in 10W+10W Class-D amplifier and 110x40mm elongated shape speaker units

Accepts both Analog input (XLR & 1/4" TS phone) and Digital Input (AES/EBU)

Headphone out for headphone monitoring. When switching from headphone out to speaker out or vice versa, the output signal fades in to avoid unexpected level difference
