OPERATION
SETTING THE GAIN
Turn the gain control fully
When sending a signal to a tape recorder with a variable input use the following procedure: Turn the gain control fully
The trim control can be used for ultra fine output level adjustment as well as for level riding during recording. It should be noted that the maximum output level of the preamplifier is reduced by the amount of output attenuation being used. For instance, if the trim is set to - 6dB the maximum output level of the preamplifier will drop from +26dBu to +20dBu. Since the LED peak indicator monitors signal level before the trim control it will always monitor the actual preamplifier headroom regardless of the trim control setting. It is best to leave the trim control fully clockwise for normal recording operations. This ensures that the preamplifier will be operated at the minimum necessary gain setting.
USING THE V2 IN
In MS mode the preamplifier accepts the Mid signal in channel 1 and the Side signal in channel 2. The channel 1 output (XLR or RCA) provides the “sum” of the inputs and the channel 2 output (XLR or RCA) provides the “difference” of the inputs. In the MS mode the CH 1 GAIN control adjust the amount of Mid signal in the “sum” and “difference” outputs. The CH 2 GAIN control adjusts the amount of SIDE signal in the “sum” and “difference” outputs. It is best to leave the TRIM controls at “0” and use the gain controls to adjust the stereo field. Equal gain on both channels will provide the widest stereo perspective while reducing the gain of the SIDE channel will decrease the width of the stereo field.
