FREQUENTLY ASKED QUESTIONS
This section give answers to some of the
most frequently asked questions regarding
the G•Major. More information can be found
via TC Support Interactive, which can be
accessed via www.tcelectronic.com
Which MIDI foot controller is the most
suitable for the G•Major?
There are many foot-controllers that works fine
with the G•Major. However, to fully utilize the
facilities in the G•Major you should look for a
controller capable of sending
MIDI Control
Changes alternating values between 0 and 127
and MIDI Program changes.
Control Changes are used for bypassing
effects, tapping tempo etc. Program changes
are used for recalling/loading presets.
What is the proper way to adjust the Input
level on the G•Major?
Play with a high level clean sound. Though the
distorted sounds may seam louder than clean
sounds in general, the highest dynamic range
is typically found in clean sounds. The Input
meter should show -3dB at peaks and -12dB to
-6dB in average.
If adjusting the Output level of your preamp (or
other device placed just before the G•Major in
the signal path) and adjusting the Input level on
the front panel of the G•Major, does not give
you the desired Input level range, you should
change the Input Range parameter found in the
G•Major I/O menu.
How to setup a G•Major with a MIDI
controllable preamp
The G•Major is easily setup with a MIDI
preamp.
• Connect MIDI Out from your MIDI board to
MIDI In on your preamp.
• Connect MIDI Thru/Out from the preamp to
MIDI In on the G•Major.
The G•Major has a MIDI mapping function that
allows incoming program changes to recall any
preset. See page 18 for more information.
How to reset the G•Major?
• Power off the G•Major on the front panel.
• Press and hold the TAP key and power on
again.
• Select either “Reset Sys Param” to reset all
system parameters while keeping your
programmed user presets or “Clear all
Presets” to clear the User bank only.
Amp switching of specific analog preamps
Contact the amp manufacturer to get
schematics on your specific preamp. Page 19
of this manual explains how the relays of the
G•Major operate.
Lost preset at power off
If you power off using the rear panel mains
switch while a preset is being edited your
changes to that specific preset will be lost. You
will not loose your settings if you use the front
panel POWER key while keeping mains power
connected on the rear panel.
However, a good rule of thumb: Save settings
before powering off the G•Major.
Uploading software to the G•Major
From time to time new software will be
available for the G•Major. To upload this
software to the G•Major you will need a PC
computer with a standard MIDI interface
installed. The software can be downloaded from
www.tcelectronic.com. Follow the instructions
given in the upload application.
G•Major hangs during software update
procedure.
Depending on the MIDI interface used you may
encounter a “download error”. Retry once or
twice and the software should update correctly.
Using the G•Major in a combo amplifier
effect-loop
Many combo amplifiers have an effect loop.
However, there are no standards for these
loops. At times it can be hard to even see
whether we are talking about a serial or parallel
loop.
A serial loop interrupts the signal path between
the preamp and the power amp - just as if they
were two separate units. This means the entire
signal from the preamp travels through the
processor and re-enters the power stage. It is
basically a one-lane road going from one place
to another.
Parallel loops offer two paths from the preamp
to the power amp. One path is a direct
connection from the preamp to the power amp
as if the amp had no loop at all. The other path
sends the preamp signal to the effect processor
(via the loop) and then routes it back to the
power amp, mixing it with the direct (dry) signal.
Most amps that offer a parallel effects loop
