Lowell CS650-SS
Volume Control with Selector Switch (Standard/Stainless)


The CS650-series is a combination volume control / selector switch for controlling the speaker volume on up to six source connections. The assembly includes Lowell's UL Listed 50W auto transformer (Model 50LVC) mounted on the left side of a 2-gang plate with six-input selector switch (Model CS6) mounted on the right side. The 50W volume control for use with 70V or 25V speaker lines provides 33dB attenuation in ten steps*. The selector switch is a two-pole, non shorting rotary style to assure complete isolation between lines. Wiring connections to the volume control are plug-in screw terminations for prewire convenience. Connections to the selector switch are 'Euro-style' screw terminals allowing the unit to be field connected for use together or independently.

The plate selection includes standard (stainless steel) or Decora-style (white, black, white/stainless, black/stainless). All Decora-style models include one 2-gang plate AND two 1-gang plates to provide maximum flexibility in system design. Units include attractive knobs and mounting screws. Mounting depth is 2-1/8" for installation in standard 2-gang or 4”SQ electrical outlet boxes with a 2-gang mud ring (by others).
