Line Powered Telephone Balancing Unit

Features Description Specifications Downloads Ask a Question
  • Provides balanced audio input and output from a normal POTS (Plain Old Telephone System) line
  • No batteries or mains required
  • Input compressor (prevents overloading of telephone line)
  • R/C & line balance controls
  • Internal tone generator for line balancing

The GS-PASTE 201 is a 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.

A 19 inch rack mount version is also available.

Audio input is line level on a balanced Neutrik XLR
