Sonifex S1

The S1 has a multitude of output connectivity: one balanced stereo XLR PGM output, two balanced stereo AUX outputs on a 9-way D-type socket, a mono clean feed output on balanced XLR (for use with a telephone hybrid), a stereo cleanfeed output on stereo balanced XLRs (for use with an ISDN/IP codec) and monitor outputs for presenter headphones, guest headphones and loudspeakers. Additional outputs are provided for talkback on a 9-way D-type socket and metering using a 15-way D-type socket....
