Controls the Channel Three Y," phone jack input level.
PRE EQ PATCH:
SEND/RETURN JACK (10)
A stereo out/in jack allows the uses of various auxiliary units (chorus, flanging, tape/digital/analog delays,
equalizers, etc.) in line before the Equalization section. To utilize this system, a stereo plug (tip/ring/sleeve)
to a "Y" cord must be used. The tip portion of the Y," stereo jack serves as the signal send (output), while the
ring portion will return the processed signal to the system. The sleeve portion serves as the ground. The Pre
EQ patch affects all three channels.
Since this is a stereo jack configuration, the first click on the jack may be used as a Pre EQ output with a
mono Y," plug if desired. This first click will not disturb the signal flow to the remainder of the system as it is
fed into the EQ section.
EQUALIZATION:
LOW EQ (11)

HIGH/MID EQ (13)
An active tone control (Peak/notch, +12 dB) that varies the high/mid frequency range.

position. There may be some situations when audible hum and/or noise will come from the loudspeaker. If
this situation arises, position the ground switch to either positive or negative (+ or -), or until the noise is
minimized.
