Each of the 4 input channels is comprised of a Euroblock connector, that can accept either Line or Mic level signals, along with a pair of RCA jacks for running consumer-level audio signals, such as a CD or media player. Input 1's Euroblock connector includes connections for a paging microphone along with an audio source. Each input includes a 2-way switch for selecting the signal type with selections for either Mic or Line.


A single 3-pin Euroblock connector provides a Line Level output signal, up to 5.0Vrms, for running to an outboard amplifier or mixer/amplifier.

VOX Function

Voice-activated ducking, or the VOX function, is available on input channel 1. This function causes attenuation of the overall output level of the amplifier when the input level on channel 1 reaches a set threshold. A designated VOX trim pot is provided for setting the audio input level required to activate ducking. A typical usage of the VOX function is to automatically lower the background music in the room while making announcements over the audio system. After the announcement is made, the background music returns to its previously set level.


The CSM 14 can be used in a table - or shelf-mount orientation with 4 rubber stick-on feet provided. Rack-mounting hardware is provided for either mounting a single unit or for mounting 2 units side-by-side in a standard 19" rack.
