Unbalanced Connections

If your preampliÞ er has RCA out-

puts, it can be connected to the ampli-
Þ er inputs as shown. The ampliÞ er will 
boost the preampliÞ er's output, up to a 
level suitable for driving speakers.

This diagram also shows how the 

Voltage Source outputs connect to 
the input posts of your speakers. (The 
Current Source outputs can be used 
instead.)

The following pages show some typical con nec tions that you might make in your in stal la tion. They show how the inputs 

and outputs of the Cinema Grand AmpliÞ er are con nected to your pream pli Þ  er and speakers.

R  = Right Channel 

 

C  = Center Channel, 

 

L  = Left Channel   

 

RS  = Right Surround (rear) Channel 
LS  = Left Surround (rear) Channel

Line-level audio signals                       
From: PreampliÞ er main RCA outputs
To:     AmpliÞ er line-level inputs 

Make sure that the positive 
speaker wires do not touch 
the negative speaker wires, 
or any chassis metal. This 

will cause a short circuit and may 
damage your ampliÞ er or speakers.
