3.4 Wiring the GMX1200H
The GMX1200H head features two LOUDSPEAKER outputs
(EXT LEFT and EXT RIGHT) that can be used to connect one or
two external loudspeakers. To get the most power from the
GMX1200H, both loudspeaker outputs should be used and
connected to speakers with minimum 8 Ohms impedance.
Loudspeaker outputs 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 of your amplifier,
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 fig. 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 fig. 3.5).
