Glensound GS-PASTE 201/R1 - Rack Mount Line Powered TBU

The Glensound GS-PASTE 201/R1 is a 19 inch rack mount line powered, heavy duty analogue telephone balancing unit. It allows professional audio equipment such as mixers, talkback systems or headphone circuits to be connected to a traditional analogue telephone line.

A tone generator has been included to help with line balancing. Once a line is connected the tone can be switched on, so that the R and C can be balanced accordingly. Instructions for this are printed on the side of the unit.Once the best balance is achieved, the tone can be turned off.

A front panel LED indicates an incoming call. There is also an audible ringer which can be turned off if required.


  • Audio input is line level on a balanced Neutrik XLR
  • Input level control
  • Multi coloured LED indicates level sent to the line


  • Audio output on balance Neutrik XLR.
  • Output level control

Telco Connections
There is an RJ-11 connector for external handset to allow dialling of outgoing calls. An On/Off Hook switch (with indicator) allows answering of calls when and external telephone is not connected.

There is also an RJ-11 connector for connection to a normal telephone line. A recessed switch switches RJ-11 telephone line pairs (there are 2 different standards used Worldwide), for worldwide compatability.
