knob to the right of the frequency selection switch. The full counter-clockwise position of the
frequency switch is OFF. In this position, there is no gain across that band, which eliminates
the need to center the boost/cut knob. A post-EQ transformer balanced insert point is available
at the normally closed INS SND switching jack in the rear panel.
The line amplifier can be used as a stand-alone module by sending a signal into the INS RET
jack on the rear panel. It is a normally closed switching jack fed by the post-EQ insert send
signal.
The FADER knob controls the level of the output signal, which is equivalent to a post-fader
direct out on a console channel strip. For lowest noise and distortion, and maximum
headroom, the fader should be operated near its 0 dB point. At its full clockwise position, the
FADER allows for a 12 dB boost using the output line amplifier for gain.
Optimum gain staging and a wide variation of tones can be obtained through the use of the
input GAIN knob, the input TRIM knob, and the output FADER knob.
Inputs and Outputs
The mic input is balanced by a Jensen transformer to receive a nominal -60 dBu balanced
input via an XLR jack on the rear panel of the unit.
The line input is a nominal +4 dBu balanced line input via a TRS jack on the rear panel.
The DI input is a nominal -42 dBu high impedance instrument input via a TS jack on the front
panel.
The mic pre output is a nominal +4 dBu Cinemag transformer balanced line output via a TRS
jack on the rear panel.
The insert send is a nominal +4 dBu Cinemag transformer balanced line output via a normally
closed switching TRS jack on the rear panel.
The insert receive is a +4 dBu balanced line input via a normally closed switching TRS jack.
The channel out is a +4 dBu Cinemag transformer balanced line output via a TRS jack.
