The RM-3 is the ideal solution for monitoring needs in various space-challenged environments such as machine rooms, video monitoring, surveillance, mobile and stationary control rooms, or theme park applications where audio monitoring is needed in a compact environment. 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. Highly visible 26-dot LED meters (left and right channel) with 4-step brightness adjustment 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.
