input selection
The rdq-6 has three independent digital processor cards, Left/Right Front, Left/Right
Surround, and Center/Sub. Each of these cards has two digital inputs and two digital outputs.
The rdq-6 allows you to select which of the inputs is active through the input selection
function. There are a number of reasons why input source selection is best performed in the
digital domain. The most significant is the reduction of crosstalk. There is infinite rejection
between input channels on the rdq-6; crosstalk is simply not possible.

How to do it. Each digital processor card accommodates the digital audio input and output
for a stereo pair of channels. On each card, you will find 1 AES/EBU input on an XLR
connector, 1 S/PDIF input on an RCA connector, 1 AES/EBU output on an XLR connector, 1
S/PDIF output on an RCA connector. Regardless of which input is selected, both outputs are
active simultaneously. To select which input is used by the rdq-6, press the
system
button
and select the
INPUT
submenu. The display will appear as shown in Figure 4. To change the
active input, simply rotate the knob below the input selection display for each of the three
digital processor cards. To switch to S2 Mode, press the
TO S2CH
button. Doing this will
cause the screen to present a confirmation display. You should remember that the output of
the rdq-6 in S2 mode appears on the Center/Sub processor card outputs. When you have set
your DAC properly, hitting the
CONTINUE
button will complete the transition to S2 mode.
While in S2 mode, the board labels will change to L/R room eq 1, L/R room eq 2, and L/R TTC.
