Example Connection Diagrams:
The Lavry Quintessence has a unique digital monitor function that can allow precise comparisons of two or
three digital sources. However, it cannot take the place of two DA converters in systems with analog
processing. The Quintessence can be used for the comparison of pre and post processing signals when
configured in one of the following manners. Each of these configurations requires the DAW to have multiple
AES/SPDIF outputs.
This configuration uses
the Quintessence as the
source DA converter for
analog processing. It is
necessary to record the
processed signal to use
the monitoring feature
of the Quintessence to
compare the
preprocessed (
flat
)
source to the post
processed (
EQ’d
) file. A
second DA converter
may be used prior to
and during recording to
monitor the processed
signal.
Once recording is
complete, it is necessary
to mute the recording
inputs in order to
prevent the potential
for feedback when the input of the Quintessence is changed to the post processing signal. In this setup,
Main
Out
would feed the analog processing, and
Monitor Out
would feed a monitor controller. Source selection on
the monitor controller would be used to select the Quintessence or the separate monitor DA converter.
During setup and recording, the monitor DA would be selected to listen to the processed signal. Once the file
is recorded, the monitoring features of the Quintessence could be used to make precise comparison of the
original and processed files playing from the DAW, and possibly a third source such as a CD player.
