mic set-ups. It is ‘pre’ Flip in the signal path so off-tape signals can be
phase reversed if required by re-patching through the line input.
GAIN (4)
The Gain control affects both line or microphone input level, dependent
upon which is selected by the Mic/Line switch. The centre detent
corresponds to 0dB gain on the line input and the gain setting will affect
signal strength to the preamp valve stage, and therefore enhancement of
that signal. The variable input gain ranges from 16 to +60dB on the mic
input, and –10 to +35dB on the line input.
LOW CUT FILTER (5)
The low cut filter is designed to remove unwanted LF noise. The filter
has a slope of -12dB per octave and operates at 90Hz. It is active on
both mic and line inputs, whichever is selected.
3.2 Tape Return
MONITOR TRIM (6)
Monitor Trim adjusts the tape monitor input gain. With a very useful +/-
20dB range it can cope with most recording systems. In addition,
internal jumper links can allow operating levels to be set at +4dB or -
10dB, as required (information on altering these jumper links can be
found in 3.6 of the technical section of the manual).
Valve stage
Like the channel preamp the Monitor input features an ECC83/12AX7A
valve stage. This is located ‘post’ Gain and Flip. There is no insert point
on the Mix B signal path.
FLIP (7)
The Flip switch swaps the Mic/Line and the Tape Monitor input signals.
When selected the Mic/Line signal is fed to the Mix B section, and the
Tape Monitor signal is fed through the main channel signal path. When
Flip is active the Gain, LF Cut and Phase Reverse switches remain tied
to the Mic/Line input, while the Monitor Trim control remains tied to
the Tape Monitor signal.
Flip is most likely to be used on mixdown so that the tape return signal
can have the full benefit of the main channel’s long throw faders,
equalisation and auxiliary send options.
3.3 Insert Point
Insert points are designed to allow external devices such as dynamics
processors to be patched into the signal path when recording or mixing.
