Tones may be sensed on either or both audio inputs. Each channel can detect the presence of 25 Hz, 35 Hz, or both audio tones simultaneously. Relay contacts are available for each condition.
The two audio outputs each pass through a 50 Hz high pass filter, to attenuate any control tones which may be present. Each TD-2 output channel provides a front panel variable gain control.
The input and output connectors are the XLR type. All inputs and outputs are balanced.
