6.5 Getting to Know Your SD-7816B Digital Audio Distributor

The Kramer SD-7816B is a high performance, dual mode, distribution amplifier for digital audio

signals. The machine can be set to operate as a single-channel 1:16 or as a two-channel 1:8 unit. Several

digital formats are supported including AES/EBU, IEC 958, S/PDIF and EIAJ CP340/1201 professional

and consumer formats with sampling frequencies up to 96 kHz.

The machine provides 2 inputs equalized to compensate for losses on 75-ohm cables. Reclocking at

each input provides 16 low-jitter digital audio outputs. The SD-7816B is designed for 75-ohm coaxial

cables on BNC connectors.

All inputs and outputs are transformer coupled. The front panel LEDs display the selected setup, the

presence of digital audio signals, and the detection of errors in the data stream.

Panel features of the SD-7816B are described in Figure 7 and Table 5.
