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 Output | BNC connector this is a TTL level square wave that can be used to provide sync to other equipment. The WC output will be the selected sample rate or the rate of the WC input. |
Internal Sample Rate | 44.1kHz TO 96kHz determined by front panel switch. |
S/PDIF Input | Unbalanced digital input 75 ohms RCA connector. |
S/PDIF Output | Unbalanced digital output 75 ohms RCA connector. |
AES Input | Balanced digital input 110 ohms XLR connector. |
AES Output | Balanced digital output 110 ohms XLR connector. |
Power | 25 watts at 115 or 230 volts, 50 or 60 Hz. Fuse size is MDL .3A for 115 volts; MDL .25A for 230 volts. |
Pilot Lamp | # 7335 |
Shipping Weight | 15 lbs (6.7kg) |
Depth Behind Panel | 10 inches (25.4cm) plus user input/output connectors. |
The Convertors | HEDD uses high Quality 24 Bit A/D and D/A Convertors made by CRYSTAL semiconductor, with an upgrade path to 192K sample rate convertors. |
