OPERATING CONSIDERATIONS (Cont’d) conference or conversation situation, with several micro- phones “live” but only one speaker talking at a time, eachInput control should be set so that each speaker results in approximately the same amount of compression, observingthat the overall level is correct f...

THEORY OF OPERATION (Cont’d) maximum of 30 dB, the second potentiometer section acts as a conventional voltage divider output attenuator for lowcontrol settings. The input transformers increase the signal voltage by 21 dB. Input 1 has a second line input, phone jack J12, which operates only in the L...

MODIFICATIONS Noise Improvement for Single Inputs: The overall signal-to-noise ratio of the SE30 may be im- proved for single-input applications by disabling the two unused input channels. This automatically reduces the noise level of the mixing circuitry without changing the gain or other character...
