Analog/Digital Stereo Matrix Switcher

The ADMS 44.22 G2 provides matrix audio switching of 4 RJ45 analog inputs, 4 XLR AES inputs, 2 RJ45 analog outputs, 2 XLR AES outputs. Matrix switching allows any/or all inputs to be assigned to any/or all outputs. The ADMS 44.22 G2 may be controlled via its front panel push-button controls, contact closures, open collectors, logic, multi-drop RS-232 serial and/or TCP/UDP Ethernet commands. Installation is simplified with RJ45 audio jacks for analogue input and output connections, XLR jacks for digital input and output connections, and plug-in euroblock screw terminal connectors for remote control.

Product Features

• 8×4 matrix audio switcher, 4 analog inputs, 4 AES inputs, 2 analog outputs, 2  AES outputs.

• Front panel push buttons are provided for input-to-output channel selection.

• 16 input “PIP” (GPI / Triggers) port (or remote control) with front panel LED indicator.

• Multi-drop RS-232 serial port and TCP/UDP Ethernet port and ASCII command set for computer/automation control.

• Three audio switching modes: Interlock, overlap, and mix.

• Internal silence sensors monitor each output and provide front panel LED silence indicators and silence alarm relay outputs. Trip level, silence delay and restore duration timing are user-configurable.

• Front panel stereo LED VU meters and stereo headphone output with front panel headphone jack and level control for output monitoring. Configurable power-up selection of inputs to outputs, mute or last source selected.

• 16 SPST relay outputs, 12 commands controllable, 4 for output silence detectors.

• Rear panel multi-turn input level trimmers and internal single-turn output level controls.

• Electronically balanced stereo inputs and outputs with low noise, and low distortion circuitry.

• Most configuration options are via rear panel dip-switches.

• RJ45 audio jacks for analogue audio I/O, XLR jacks for digital audio I/O, and plug-in euro-block screw terminals for remote-control connections.

• Fully RFI proofed.

• 1-RU 19” rack chassis.
