Behringer V-TONE GMX212 Manual - Page 9

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. 3.3 Live setup with a MIDI foot controller BEHRINGER ULTRASTACK BG412V Sound Reinforcement System In this illustration, we've omitted the headphones and the additional equipment from figure 3.1; this illustration serves as an expansion of the standard setup. You can use the MIDI foot controller to control channel and effects 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 your mixer 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 SPEAKER OUT connectors ((32)) used for connecting an external loudspeaker. Loudspeaker Output Left Loudspeaker Output Right Input Line Out 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).
