4 Front & Rear Panels Stereo Channel & Master Control Sections y o !0 !1 !3 !4 !5 q w e r t ui !2 !6 q ST Input Select Switch Selects which of the two input signals, from ST Input jacks A or B, will be used. In the raised position (?), ST Input jack A is selected while the lowered position (>) selects ST Input jack B. w ZONE Select Switch The same as number r on page 3. e PEAK Indicator Indicates peaks in the signal of the post buffer amp. The indicator will light red when the level reaches +17dB to warn that clipping is imminent. r SIGNAL Indicator The indicator will light when the signal level exceeds -10dB in the post buffer amp. t Channel Volume The same as number u on page 3. y COMPRESSOR The COMPRESSOR controls the signal's volume level when the level set with the TH (Threshold) Control is exceeded. The Compressor is effective on input channels 1-8. (Refer to page 9 for more information.) • COMPRESSOR ON/OFF Switch Switches the COMPRESSOR ON/OFF. • COMPRESSOR Indicator Lights when the COMPRESSOR is activated. • TH Control Sets the input level (Threshold level) at which the compressor will function. Rotating the control to the right allows the compressor to function at lower volume levels. • RATIO Control Sets the ratio of compression that is applied to the signal when it exceeds the threshold level. Rotating the knob to the right increases the amount of compression. When the knob is turned fully to the left, the signal will not be compressed. u PAGING The PAGING function terminates all signals from each of the INPUT channels (1-8, ST), INSERT IN and STACK IN input jacks and only allows the signal from the PAGING MIC/LINE input jack to be produced. This function can also be used with a control signal from an emergency announcement system. (Refer to page 9 for more information.) • PAGING GAIN Control Controls the input sensitivity of the PAGING MIC/ LINE input jack. An optimum balance between the S/N and dynamic range is achieved when the PEAK indicator lights occasionally. • PAGING PEAK Indicator Indicates post head amp level peaks in the PAGING MIC/LINE signal. The indicator will light red when the level reaches +17dB to warn that clipping is imminent. • PAGING SIGNAL Indicator The indicator will light when the PAGING MIC/ LINE's post head amp signal level exceeds -10dB.
