off, the LED will illuminate if voltage is being fed from an external source. (i.e. when using a direct split in a remote recording application.)
4.PHASE REVERSE The phase reverse switch (labeled ∅) reverses the absolute polarity of the music signal at the input of the preamplifier. The switch illuminates green and provides power for a sealed gold contact relay located on the preamplifier circuit board. This eliminates signal wiring to the front panel and switch contact performance problems.
5.20dB ATTENUATOR The 20dB attenuator switch (labeled
6.PEAK INDICATOR The LED peak indicator, which monitors the output signal, turns green at
7.MEMO PAD The Memo pad can be used with
B.SETTING THE GAIN
1.Turn the gain control fully
2.When sending a signal to a tape recorder with an input attenuator use the following procedure: With the sound source present, turn the preamplifier gain control clockwise until the peak LED begins flashing red, then reduce the gain until the red stops flashing. Since red indicates a peak level which is 12dB before clipping (6dB in unbalanced mode) it is OK for it to come on periodically during recording. If peak indicator flashes red excessively with the gain control in the fully counterclockwise position, engage the
3.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
