Interface Equipment - Option 1

Standard headset and cabling are shown. Other custom cabling and headsets are available. Interface cables can be ordered as custom equipment.

Color Key:
Use of an intermediate extension cable between headset and Y-cable is NOT recommended, as the shields will not be properly grounded.
Length of cable (ACBL-4x3x) is to be specified by the customer.
This breakout panel (IPNL-8x) is NOT the standard configuration. It is shown only to support special legacy installations.
Notes:
  • Headset shown is model HS-TX-PH-10-4R. Stereo headset, 4-Pin Male XLR connector.
  • Cable shown (with green circle) is ACBL-4x3x. Two 3-Pin XLR connectors plug into the breakout panel, one 4-Pin XLR plugs into the headset.
  • Standard breakout panel is IPNL-8XR, shown at top. The cable to attach to the 37-Pin DB Connector on the Waveform Synthesizer has a standard length of 48".



Interface Equipment - Option 2

Notes:
  • Breakout cable shown is ICBL-8XR. There are eight 3-Pin Male XLR connectors (indicated by the blue box) that pass audio from the DACS to the headset or other output devices. There are eight 3-Pin Female XLR connectors (indicated by the red box) that carry audio from microphones or other inputs to the DACS.
  • ICBL-8XR standard length is 48". The length between the DB-37 connector and the split-point is 30".
  • Also shown is ACBL-4x3x (on right). This cable is required if you wish to connect headsets to ICBL-8XR.



Interface Equipment - Option 3

Notes:
  • Cable shown is ICBL-8x4.
  • There are eight 4-Pin Female XLR connectors that provide direct headset connections.
