The SONIFEX RB-DA6 : AUDIO DISTRIBUTION AMPLIFIER 2X6 is a multi-function distribution amplifier offering either six-way stereo, dual six-way mono, or twelve-way mono operation. The front panel has a power indicator, two pre-set input gain controls and a recessed switch to select mono or stereo operation. There are two inputs using 3-pin XLR connectors, which may be fed with dual mono sources or a single stereo source to feed six outputs. Alternatively, one mono input can be distributed to twelve outputs. All audio connections may be wired balanced, or unbalanced, without loss of level, for use with domestic equipment. Power is connected using an IEC inlet, which has an associated fuse and voltage selector switch. All connections are on the rear panel.
