Analog Input: Transformerless balanced floating stereo output on XLR-m
connectors. The default calibration is +20 dBu = Digital zero. Gain adjust trims
are on the back panel. The analog input range for 0 dbfs is adjustable form +16
to +26 dBu
Word Clock Input: BNC connector takes a TTL level signal at the sample rate to
sync the A\D to the external sample rate. HEDD will sync from 20 kHz to 192K
kHz. The input impedance is 75 ohms.
Word Clock Outputs: these BNC connectors are a TTL level square wave that
can be used to provide sync to other equipment. The WC outputs will be at the
selected sample rate or the rate of the WC input.
Internal Sample Rate: 44.1kHz to 192kHz determined by front panel switch.
