9 V-TONE GMX1200H/GMX212/GMX210/GMX112/GMX110 User Manual
If you want to use another guitar preamp, or a modeling amp (e. g. the V-AMP 2
or the V-AMP PRO), connect it to the SLAVE IN connectors (except for the GMX110
and GMX112). The V-TONE now operates only as a power amp, with its preamp
section inactive.

Fig. 3.3: Setup with a MIDI foot controller and an external loudspeaker
In this illustration, we’ve omitted the headphones and the additional equipment
from gure 3.1; this illustration serves as an expansion of the standard setup.
You can use the MIDI foot controller to control channel and eects changes,
volume, Wah and so on. (Additional information about MIDI can be found in
section 4.3). The LINE OUT signal with the speaker simulation can be fed into
yourmixer or your P.A. system’s stagebox.
External guitar loudspeakers can be connected to the loud-speaker outputs of the
GMX212 in order to get more punch and higher volume on the stage. You can do
this in two ways: use two separate loudspeakers for stereo applications, or use a
single stereo box (e.g. the BEHRINGER ULTRASTACK BG412V).
Instead of loudspeaker outputs, the GMX110 and GMX112 feature single
SPEAKEROUT connectors ((32)) used for connecting an external loudspeaker.
3.4 Wiring the GMX1200H
The GMX1200H head features two LOUDSPEAKER outputs (EXT LEFT and
EXTRIGHT) that can be used to connect one or two external loudspeakers.
Toget the most power from the GMX1200H, both loudspeaker outputs should
be used and connected to speakers with minimum 8 Ohms impedance.
Loudspeakeroutputs are automatically muted as soon as you activate the tuner
or connect a set of headphones (see section 5.1). To assure optimal and safe use
ofyour amplier, please also read section 6.2.
When the GMX1200H is used with a single BEHRINGER ULTRASTACK BG412V,
the rear panel switch of the BG412V must be in the stereo position and the two
outputs should be connected as shown in g. 3.4.
When using two speaker cabinets to form a classic full-stack please make sure the
impedance of each speaker cabinet is between 8 to 16 Ohms (see g. 3.5).
