Kramer 3232S-XL 32x32 Analog Balanced Stereo Audio Matrix Switcher

The Kramer 3232S-XL is a 32 by 32 matrix switcher for analog balanced stereo audio, part of the Lassen XL series. Any of its 32 balanced stereo inputs can be routed to any of its 32 balanced stereo outputs, independently and simultaneously, which is what separates a matrix from a simple selector.

Input and output gain and attenuation are adjustable per port, so sources arriving at different levels can be trimmed inside the switcher instead of upstream. Control is over RS-232, RS-422, or Ethernet on an RJ-45, letting it sit under a room controller or a network management system. The rear panel also carries two sync connections and an AC power inlet.
