SONIFEX S2-CT Telco Channel with EQ
SONIFEX S2-CT Telco Channel
The telco input channel controls the connection to a telephone balance unit (or hybrid). It has one balanced line level mono input on Neutrik XLR, and one balanced line level cleanfeed output to return to the hybrid. Selecting the CUE/PFL & T/B button routes the pre-fader input signal to the monitoring system where the signal can be heard via headphones and/or loudspeakers. In addition, talkback is automatically routed back to the caller via the cleanfeed system. This enables the presenter, or technical operator, to communicate with the caller prior to putting the caller live to air. PFL can be automatically disabled when the fader is opened.
There is a logic remote output to place the hybrid “on hold” by using the LINE HOLD button. The remote output on the 9 way D-type plug is fed from an NPN opto-isolator and it can be made momentary or latching.
Selecting the PGM and/or AUD buttons routes the channel audio output to the PGM and/or AUD mix busses. The buttons are illuminated in green to indicate the routing status. Changing the status of the PGM button is inhibited when the channel is “live”.
Selecting the PGM button also routes the channel to one of the two true cleanfeed busses (jumper selectable). When selecting only the AUD button, for example to record off-line telephone conversations, a cleanfeed is generated via the channel mix-minus system. When both PGM and AUD are selected the channel operates in the true cleanfeed mode, sending the PGM signal to the cleanfeed bus.
Equalisation is fitted as standard and is enabled by the EQ button, providing 10dB cut and boost at HF (6.5kHz) and LF (100Hz). The EQ button places the equalisation in and out of the signal path and is illuminated yellow when the EQ is active.
