Cerwin-Vega CVM-1022 manual Front Panel Controls Channel Control Section, Peak LED Indicator

FRONT PANEL CONTROLS – CHANNEL CONTROL SECTION

(1). PEAK LED INDICATOR

This LED indicators lets you check the level of the signal input to the channel. The peak indicator lights when the input signal reaches 5dB below the channel’s clipping point. This indicator shows the level of the Post-EQ / pre-fader signal. If the PEAK indicator lights more than briefly on high-level transients, you should use the GAIN control to decrease the input sensitivity of the channel. If this does not work, reduce the output level of the connected source.

(2). GAIN CONTROL

According to the level of the input signal, use this knob to adjust the input to an appropriate level. The best balance of S/N and dynamic range will be achieved if you adjust the GAIN control so that the peak indicator lights occasionally. This control adjusts the channel’s mic input sensitivity between -50dB and -6dB and the line input sensitivity between -30dB and +14dB. The mono/stereo combination input channels have a sensitivity of +20dB to -20dB.

(3). HPF (High-Pass Filter, cut frequencies below 75Hz)

This switch toggles the HPF on or off. To turn the HPF on, press the switch in ( ).

(4). 3 BAND EQUALIZER CONTROLS

This is a 3-band equalizer with center frequencies, range and type as shown below. The frequency response is flat when all knobs are in the “0” position.

CONTROL	MAX.	FREQUENCY	TYPE
	BOOST/CUT
HIGH	±15dB	12kHz	Shelving
MID	±12dB	2.5kHz	Peaking
LOW	±15dB	80Hz	Shelving

(5). AUX CONTROLS

This knobs control the level of the signals sent to AUX bus. This control is placed before the channel volume; it will not be affected by the channel level volume.

(6). EFX CONTROLS

This knobs control the level of the signals sent to EFX bus. The channel signals mixed by this bus have their overall level set by the EFX SEND Control to the EFX SEND jack on the front panel. Since this control is placed after the channel fader, the signal level will be affected by the channel fader setting.
