 SMX 1616 A 16x16 Stereo Audio; 2 Slots 70-599-04 Retired

The SMX Stereo Audio Matrix Switcher Boards are designed for routing balanced or unbalanced stereo audio signals. They are available in three I/O sizes: 8x4, 8x8, and 16x16.

Features

  • Switches balanced or unbalanced stereo audio signals — Accepts both balanced and unbalanced stereo audio signals on captive screw connectors.
  • Audio input gain and attenuation — Allows users to set the level of gain or attenuation for each audio input channel, eliminating noticeable differences in volume when switching between sources.
  • Audio output volume adjustment and muting — Can be set dynamically for each channel through the SMX Frame front panel, Ethernet or serial control ports, eliminating the need for an audio preamplifier in many system designs.
  • Audio breakaway — Provides the capability to break an audio signal away from its corresponding video signal, allowing the audio channels to be operated as a separate matrix switcher.

Note: When installing this board in an existing SMX Frame, new SMX Frame firmware may be required; contact your Extron technical services representative for more information.
