AD IN 2

If the optional 24/96 AD converter module is installed, this input can be used to convert an external analog signal. To avoid clip- ping, the input level should not exceed +12 dBu (+12 dBu corre- sponds to full digital gain of 0 dBfs). Excessive input levels are indicated by the AD OVL LED.

If no connection is made here, the output signal of the GS1 is routed to both channels of the converter.

TIP: AD IN 2 can also be used as an insert for external pre-conver- sion processing. Connect the analog outputs of the GainStation 1 to the external processor‘s inputs and the processor‘s outputs to AD IN 2 on the Gain Station 1. One channel of the converter output will contain the dry or unprocessed signal, while the other channel will contain the processed signal.

AD IN 1 MUTE

Channel 1 of the converter is internally connected to the analog output, so that the AD OVL LED is always active. If the converter is not being used, this connection can be bypassed via the AD IN 1 MUTE switch so that the LED does not continuously blink or illuminate.

TIP: If no converter is installed, this switch should always be activated.

DIG. OUT

The converted S/P-DIF signal is routed in parallel to the RCA and optical outputs. The signal is in professional format with no sample rate data in the status block.
