Broadcast Tools SS 4.4 4x4 Stereo Audio Matrix Switcher

Product Description

The Broadcast Tools® SS 4.4 provides matrix audio switching of 4 stereo inputs to 4 stereo outputs. Matrix switching allows any/or all inputs to be assigned to any/or all outputs. The SS 4.4 may be controlled via front panel switches, contact closures, open collectors, logic and/or the multi-drop RS-232 serial port (USB or Ethernet optional). Installation is simplified with plug-in euroblock screw terminals.

Features

• Separate input selection pushbuttons are provided for each output channel.
• Three switching modes; Interlock, overlap and mix.
• Internal silence sensor monitors output one and is equipped with a front panel LED indicator; SPDT alarm relay and adjustable SS alarm delay and restore timing duration.
• Stereo LED VU meters with front panel output selection switch.
• Stereo headphone amplifier with front panel output selection switch, headphone jack and level control.
• Stereo powered monitor output with front panel output selection switch and level control.
• Power-up selection of inputs to outputs, mute or last source selected.
• Most configuration options via rear panel dipswitches.
• 16 input "PIP" (GPI / Triggers) port (or remote control) with front panel LED indicator.
• Four open collector status outputs or programmable via burst commands.
• Four SPDT relays with selectable multiplex function on inputs assigned to output two.
• Multi-turn input and output level controls.
• Electronically balanced stereo inputs and outputs with low noise and distortion circuitry.
• Multi-drop RS-232 serial port (USB and/or Ethernet optional) with power and data activity LED.
• Multiple units may be cascaded to expand inputs.
