[. . . ] When in the microphone mode, 24 Volt phantom power shall be applied to the Input 2. 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. 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. [. . . ] Copies of this statement may be obtained by contacting Peavey Electronics Corporation, P. O.
