The Broadcast Tools SS 16.4 provides matrix audio switching of 16 stereo inputs to 4 stereo plus 4 monaural outputs. Matrix switching allows any or all inputs to be assigned to any or all outputs. The SS 16.4 may be controlled via front panel switches, contact closures, 5-volt TTL/CMOS logic and/or the multi-drop RS-232 or RS-485 serial port. Installation is simplified with removable screw terminals (Euro).

• True matrix switching, any or all inputs may be assigned to any or all outputs.
  
• Three switching modes. Interlock, overlap and mix.
  
• Logic functions via microprocessor and non-volatile memory.
  
• Internal audio activity/silence sensors monitor all four-output channels. Each is equipped with front panel "ACT" LED indicators; adjustable alarm delay and restore duration. Sensitivity is factory set at -34db.
  
• Front panel input selection switches are provided for each input channel with separate output indicator LED's.
  
• Power-up selection of inputs to outputs, mute or last source selected.
  
• Sixteen user configured macros.
  
• Most configuration options via rear panel dipswitches.
  
• 24 input GPI port (PIP) with LED indicator.
  
• 16 open collector channel status outputs or programmable via burst commands.
  
• 8 spst relay outputs. Programmable via burst commands.
  
• Multi-turn input level controls.
  
• Single turn output level controls.
  
• Electronically balanced stereo inputs.
  
• Electronically balanced stereo and monaural outputs.
  
• Remote control of front panel functions and status.
  
• Multidrop RS-232 or RS-485 serial port with data activity LED.
  
• Multiple units may be cascaded to expand inputs.
  
• Depluggable screw (EURO) terminals for ALL connections.
  
• 2-RU chassis.
