[. . . ] Channels 3 and 4 shall be electronically balanced line-level inputs with Channel 4 including stereo RCA jacks. Additionally, the output from Channel 4 input shall be made available via an electronically balanced output with a Eurotype connector and a separate level control. The module port shall be capable of controlling both mute buses. Depending upon the module chosen, it can be set up for master configuration. When the input signal to an input module commands a mute function, Channels 1-4 shall be muted. Only Channel 1 shall have a continuously variable mute threshold control on the rear panel. Setting this control fully clockwise shall defeat the Channel 1 mute function. The mute level threshold for Channel 1 shall be increased as the control is turned clockwise. When the signal level in Channel 1 exceeds the mute threshold, Channels 2-4 shall be muted. Channels 1 and 2 shall include a switch to defeat its muting function.
