32 & 33 LINE OUT BALANCED
These are the frequency-corrected (compensated) and balanced right and left
channel line outputs. Pin 2 and 3 of the XLR jack carry the signal, pin 1 = N.C. or
ground depending on the position of the Ground switch (34).
You can insert the signals routed through these outputs directly into a mixing
console or recording gear equipped with balanced inputs. The advantage of a
balanced circuit is that this type of connection will not create a ground loop,
provided of course it is wired correctly. Dial in the desired signal level for the two
balanced line outputs by adjusting the Level knob (31).
A tip from the designer:
The level of the line output is determined by the following factors: the input level
(Gain), the Volume knob as it is set in the given operating modes of the preamp,
and to a certain extent, the settings of the tone controls, as well as the position of
the Master knob.
Those are a lot of variables to be dealing with, so I recommend you first program
presets to taste, then dial in the best possible level for any signal processor you
may have connected, and finally adust the output level using the Level knob.
Certainly the best way to go about this is to call up the various presets and dial in
a setting for each that doesn't overload the output even at higher volume levels.
While you're at it, make sure that all of these levels are a reasonable match for
the input sensitivity of whatever recording device or mixing console you are using.
You can always fine-tune the level for each preset by means of the connected
device's input sensitivity or gain knob on.
34 LINE OUT GROUND
This switch assigns pin 1 of the XLR socket to ground (Ground to Pin 1). You'll find
this option comes in handy when you want to earth the circuit you have routed to
a mixing console or recording device.
35 LEVEL
This button determines the output level of the stereo output jacks. Press the
button to set a higher level (up to 10 dB) suitable for driving less sensitive power
amps. Do not press if you need a lower level (down to -10 dB) to feed the signal
to additional signal processors or extremely sensitive power amp inputs.
36 STEREO OUTPUT RIGHT
This unbalanced ¼" line out jack carries the preamp's right channel signal. You can
patch the signal routed to this jack to a power amp or a signal processor using a
shielded cord equipped with ¼" plugs.
37 STEREO OUTPUT LEFT
This unbalanced ¼" line out jack carries the preamp's left channel signal. You can
patch the signal routed to this jack to a power amp or a signal processor using a
shielded cord equipped with ¼" plugs.
38 FX LOOP RETURN: RIGHT
This is the right channel input for the FX loop. Connect this input to a signal
processor's right output/send jack using a shielded cable equipped with ¼" plugs.
