ART Pro Audio SGX LT - Guitar Preamp with F/X - Manual (Page 9)

HEADPHONE OUTPUT
A headphone output is located on the rear panel. The headphone output is a
standard 1/4" stereo jack. Any headphones may be used with this jack. Use the
Output slider to set the final output level for your headphones.
MIDI IN
This jack receives the MIDI program change messages. It enables you to change the
presets of the SGX LT from an external source such as an ART X-11 or X-15, a
computer equipped with MIDI ports and associated software or a sequencer.
BYPASS JACK
The Bypass/Inc jack may be programmed to either bypass the SGX LT or access the
Increment Preset Mode. A footswitch and any two conductor cable is intended to be
used with this jack. A momentary (normally open) switch should be used. If the
jack is programmed for the bypass feature, each time the footswitch is activated,
(hot connected to ground) the SGX LT will be bypassed. The default setting for
the Remote Jack is Bypass Mode.
This jack may also be programmed to increment up through a user selected set of
presets. The maximum number of presets you may select for this function is one
hundred twenty-eight. Only one hundred twenty-eight presets can be accesed at one
time because that is the maximum amount of presets allowed for by the MIDI
standard.
Example four and five in Appendix B show how to program the REMOTE jack for
BYPASS or INCREMENT PRESET.
REMOTE JACK(CHANNEL SELECT)
The REMOTE jack switches the preamp between the clean and dirt channel. A
footswitch and any two conductor cable is intended to be used with this jack. A
momentary (normally open) switch should be used. Each time the footswitch is
activated, (hot connected to ground) the channel switches.
CONTROLS AND OPERATION
PREAMP CONTROLS/CLEAN CHANNEL
CLEAN GAIN
To adjust the input gain of the clean channel use the Clean Gain control. The
control range of input level is 0 to 11. When set at zero, no signal is allowed
to enter the preamp so you will have no output. At eleven, maximum signal is
achieved. Set this control so your Signal LED is lit while you're playing and the
Clip LED lights with sharp attacks. Be careful not to set this control to high
because you might clip the digital effects. Monitor the digital section by moving
the Mix slider fully to the right and listen to the output. After you have set
your input gain, set your Mix control.
