DESCRIPTION

INPUTS

Incoming AES/EBU formatted digital audio data from Inputs 1 and 2 is applied to

individual input transformers. Input termination resistors at 75 ohms for BNC

inputs or 110 ohms for XLR inputs can be switched in or out of the circuit with the

front panel Input Term switch. Inputs should always be terminated unless they

are looped thru to another device or DDA input. The last device or input should

always terminate the line.

INPUT EQUALIZERS

The input signals feed automatic cable equalizer circuits. Input equalization

should only be necessary for extremely long input cable lengths and should only

be used if proven to be necessary. Automatic equalization is enabled by pressing

the front panel button labeled Input EQ. The automatic equalizer provides only

the minimum amount of boost required to compensate for excess cable roll-off to

avoid over-equalization, which can degrade noise margins. Input equalizers work

independently for Input 1 and Input 2.

RECEIVERS

When input re-clocking is enabled, the equalized AES/EBU data stream is

applied to the receiver circuit which recovers the clock and synchronization

signals and separates the audio and digital data. The audio data may be 16 to 24

bits at sample rates from 27 to 192 kHz.
