Junger Audio d02 - Digital Dynamics Processor - Manual (Page 26)

The processing of digital audio signals in the signal processor requires
a machine-specific format. Special interface circuits are therefore
available to convert to standardised digital interface formats.
Additionally, an analog output signal is available. A stereo - D/A
converter with a resolution of 20 bits generates an analog signal with
very high audio quality. This signal is fed to balanced output
drivers.The gain of the balanced analog output driver circuit for each
analog output can be adjusted on the rear panel, so that the
maximum possible analog output level can be adjusted to be any
value in the range from +6dBu to +22dBu. D/A-converter
(The maximum possible analog output level here is the analog output
level when the output level meter shows 0dBFs full scale digital level
and the D/A converter is being fed with a digital signal at 0dBFs -
the maximum possible full scale level that can be represented
digitally).
If the internal digital reference level is reduced to below 0dBFs then
the maximum analog output level will be correspondingly reduced by
the action of the limiter.
For example if the internal digital reference level is reduced to -
9dBFs (9dB below the maximum possible level that can be
represented digitally) then the actual maximum digital level that will
be received by the D/A converter will be 9dB below the maximum
possible digital level. In this case the range of adjustment for
maximum analogue output level will be -9dBu to +13dBu.
The design of the electronically balanced analog output drivers is
such that the output level is maintained even when driving an
unbalanced load.
