Connecting the A-9755/A-9555—Continued

The A-9755 can be used as a power amplifier with a 
separate preamp.
In this case, use an analog audio cable to connect the 
A-9755’s MAIN IN jacks to the preamp’s output jacks.
Connect the speakers to the A-9755, and connect the 
playback components to the preamp.

Notes:
• Do not connect a component that does not have an 

output volume control, because the sound will be out-
put at maximum volume and may damage the A-9755 
and your speakers.

• To turn on the MAIN IN function, press the [POWER 

AMP DIRECT (MAIN IN)] button for 3 seconds 
until the indicator lights up (page 17).

If you connect other Onkyo components to the 
A-9755/A-9555 with the appropriate 

 and audio 

cables, you can use the following system functions. 

 

cables are special cables solely for use with Onkyo 
products (no 

 cables are supplied with the 

A-9755/A-9555).

Auto Power On
When you turn on the power or start playback on a com-
ponent that’s connected to the A-9755/A-9555, the 
A-9755/A-9555 will turn on automatically. And when 
you set the A-9755/A-9555 to Standby, all connected 
components will go on Standby as well (the 
A-9755/A-9555’s POWER switch must be set to ON for 
this to work).

Direct Change
When playback is started on an audio component con-
nected via 

, the A-9755/A-9555 will automatically 

select that component as the input source.

Remote Control Operation
You can control all components in your system by using 
the A-9755/A-9555’s remote controller. See page 8 for 
more information.

With 

 (Remote Interactive), you can control your 

-compatible Onkyo CD player, Tuner, and so on 

with the A-9755/A-9555’s remote controller.
• To use 

Notes:
• Push each plug in all the way to make a good connec-

tion.

• Use only dedicated 

 cables for 

 connections 

(no 

 cables are supplied with the 

A-9755/A-9555).

• The A-9755/A-9555 has two 

 jacks. They’re all 

the same, so you can use either of them.

•

 jacks should be connected only to Onkyo compo-

nents. Connecting them to another manufacturer’s 
component may cause the A-9755/A-9555 to mal-
function.

• Some components may not support all 

 functions. 

See the manuals supplied with your other Onkyo 
components for more information.

• When using the A-9755 as a power amplifier (MAIN IN 

function), the 

 system functions are unavailable.
