Digital Music Ground Control & Module
GCX provides 8 audio loops. Loops are implemented with relays for absolutely no signal coloration. High grade relays are used which feature bifurcated gold contacts and are sealed in nitrogen filled enclosures. This insures maximum reliability and no degradation of audio performance over time.
Each audio loop can also be used as a latched or momentary switch. This allows control of footswitch functions such as amplifier channel switching and bypasses on non-MIDI effects. GCX will phantom power Ground Control via a standard 5-wire MIDI cable.
Also included are two 1/4 inch feed-thrus (front to back) with in-line unity gain buffer amplifiers. These exceptionally transparent buffers feature a 1 megohm input impedance to optimize guitar pickup tonal quality while providing many other benefits such as no signal degradation, greatly attenuated switching noise, and no "squealing" when switching between Preamps.
