The circuit of HCD-RH7000 is same as RDR-HX series basically.
Only the yellow color parts above are modified from RDR-HX series.
Firstly, the remote command signal is not same as RDR-HX series.
DAR-RH7000 uses the remote command for Home Audio models, not for Home
Video models.
Video models.
And, the front panel construction is also changed.
Secondly, the software of DVD-R system circuit is modified.
For example, the opening screen on the display is the one for DAR-RH7000, not
for RDR-DX series. And, some new function screen for tuner and surround sound
system are also added newly.

Thirdly, Interface CPU for SA-WSRH10 is added newly.
This IT CPU controls SA-WSRH10 operation by the customer’s control input
which is detected in HCD-RH7000.

Finally, the communication signal lines with SA-WSRH10 are gathered into one
cable physically for an easy connection.

This block diagram explains the operation of SA-WSRH10.
(1) IT CPU (IC604) in HCD-RH7000 outputs the control signal to SA-WSRH10.
AMP CPU (IC1001) in SA-WSRH10 receives the control signal and set the
sound output mode.

(2) By the control signal from IT CPU(IC1001) in HCD-RH7000, AMP
CPU(IC1001) controls the power supply circuit.
CPU(IC1001) controls the power supply circuit.
If there is no input from IT CPU, SA-WSRH10 doesn’t start the power supply
operation.
