These inputs are electronically isolated with RF filters to prevent extraneous signals, and fed via multi-turn preset gain controls on the rear panel to two pairs of electronically balanced and isolated outputs on Neutrik XLRs.\u003c\/p\u003e\n\u003cp\u003eThe rear panel gain controls are multi-turn presets to allow accurate gain setting and are also recessed to prevent accidental movement.\u003c\/p\u003e\n\u003cp\u003ePower is provided by an internal switch mode power supply, with a wide input range. There is also an input for external 12V DC power.
