SPL SMC 7.1

The SMC 7.1 handles analog monitoring for eight channels. It takes two 7.1 sources and two stereo sources, which allows two productions to be compared. A subwoofer can be added to a stereo source with the LFE button. Each speaker can be switched on or off, and the unit remembers the speakers last used for each source.

Solo-In-Place turns the speaker switches into solo buttons, so a single speaker is heard at its own position. Solo-To-Center places the chosen speaker on the center channel for critical listening from the front. A pair of stereo speakers can be connected to an alternative output. Level is set with a 45 mm aluminium knob that drives an 8-level potentiometer, and a mute function quickly silences the speakers. Headphones can be used instead of the speakers and have their own volume control.

An optional Expansion Rack mounts the unit in a 19-inch rack. Its switch passively routes the stereo output to four stereo outputs, adding three stereo pairs next to the 7.1 array. Connections are balanced XLR and DB25 analog, plus a 6.35 mm TRS headphone jack. The unit has an internal linear power supply with a toroidal transformer.
