SDP-2 Digital Surround Sound Processor/Controller
Now, suppose you want to change the Record /Zone2 assignment to the CD
input. To do this, press CD and press and hold REC/ZONE 2 until the red
front panel LEDs turn off, and the display shows:
REC/ZONE 2 OUTPUTS
SAME AS MAIN
You have now cleared the previous Record/Zone 2 assignment. To assign
CD to the Record /Zone 2 outputs, press and hold REC/ZONE 2 again. The
red LED above the front panel REC/ZONE 2 button as well as the red LED
above the CD input will light and the display will show:
CD ASSIGNED TO
REC/ZONE 2 OUTPUTS
As protection against feedback, the TAPE and VCR1 inputs are normally
blocked from being used.as sources for the Record and Zone 2 outputs. This
default condition can be changed in the Input Configuration menu as
follows.
Use MENU & and Y to select REC/ZONE 2, then press SELECT. The
MENU A and ¥ buttons will select ANALOG, DIGITAL, or BLOCKED as
the state of the input.
ANALOG allows maximum flexibility by utilizing both the digital and
analog connections of a digital source component (provided both are
attached). The SDP-2 processes the digital input signal for the main zone,
and simultaneously routes the analog input signal to the Record and Zone
2 outputs. Since no D/A converters are necessary for the analog input
signal, the functionality in the Main zone is not compromised.
DIGITAL routes the digital signal, assigned to the input, to the SDP-2's 20-
bit Digital to Analog (D/A) converters. After conversion, the signal is sent
to the Record and Zone 2 outputs. As this setup bypasses the D/A convert-
ers in the source component, and utilizes the 20-bit D/A converters in the
SDP-2, sound quality can be dramatically improved when recording or
listening in Zone 2. This setup automatically engages Stereo Bypass.
BLOCKED simply blocks the input from being sent to the Record and Zone
2 outputs. This prevents feedback from occurring with devices that have
both an input and output attached to the SDP-2 (Tape, VCR, etc.).
NOTE: Removing the block from
any input which has both an input
and output attached may cause
damaging feedback.
