This additional loudspeaker should be able to handle at least 30 Watts @ 4 Ω (GMX110) and 60 Watts @ 4 Ω (GMX112) respectively. The GMX212 and GMX1200H feature two LOUDSPEAKER-outputs (EXT LEFT and EXT RIGHT) for connecting two loudspeakers or a single stereo loudspeaker unit. The output power rating is 60 W per channel. To assure optimal power delivery from the amp, you should use 8-Ω loudspeakers that can handle at least 60 Watts. This goes for all models: You can also use loudspeakers with higher impedance values, but this lowers proportionally the power delivery as the resistance increases. Doubling the impedance halves the power value (double the Ohms = half the Watts). ◊ Since SPEAKER and LOUDSPEAKER outputs are connectors where amplified signals are given out, never connect equipment with line-level inputs to these two connectors, e. g. mixer inputs. 6.3 MIDI connection The MIDI standard (Musical Instruments Digital Interface) was first developed at the beginning of the '80s, with the goal of enabling mutual communication between electronic instruments of various manufacturers. Over the years, the number of possible MIDI applications has increased substantially; nowadays, it is perfectly normal to connect entire studios via MIDI. At the center of this network is a computer with a sequencing software, used to control not only keyboards but also effects processors and other peripheral equipment. In such a studio, you can control your V-TONE in real time from a computer. Using a MIDI footswitch presents itself as a great idea, especially in live applications, because it allows you to control not only effect parameters but also switch between channels and effects. The standard 5-pole DIN MIDI connector is located on the rear of your V-TONE. To connect your V-TONE with other MIDI equipment, you will need a MIDI cable. Pre-packed cables available at music stores are used for this purpose. Such cables should not be longer than 15 m (45 ft). MIDI IN receives MIDI control data. The receiving channel is adjusted using the CHANNEL and IN/OUT key combination On = Omni means that MIDI data are being received and processed on all channels (compare section 4.2). 7.
