This is an optional sync board for the RB-TGHD Multi-Channel HD Tone Generator. It will accept a digital audio input running at the desired sample frequency between 32 kHz and 192kHz. When using the RB-SYE sync board, the Channel Status information that is encoded in the input data signal is copied to all digital output channels on the RB-TGHD. The RB-SYA Analogue Video Sync Board and the RB-SYD Digital Video Sync Board are also available for both the RB-TGHD Multi-Channel HD Tone Generator and the RB-SC2 Dual Sample Rate Converter. The RB-SYW (distributed word clock sync) is also available for the RB-TGHD.
