StereoMixer is an 8-input, 2-output stereo mixer for line level sources. It is an ideal utility mixer that can be used to combine 4 stereo or 8 monaural sources. StereoMixer can produce either a stereo or mono output, selected by the Output Mode switch. In Stereo mode, 4 stereo sources are combined to a stereo output. In Mono mode, all 8 inputs are combined to a mono output. Each input will accept either a balanced or unbalanced source. A level control for each input provides adjustment from OFF to +10 dB of gain. All circuitry is direct-coupled and transformerless for absolute sonic integrity. Audio inputs and outputs are via plug-in euroblock connectors. StereoMixer is 1/3 rack width and can be mounted in an optional rack shelf, or wall-mounted with optional wall/cabinet mounting brackets. StereoMixer is powered by an internal AC power supply.
