Connecting Additional Amplifiers
This receiver has more than sufficient power for any home use, but it is possible to add additional amplifiers to
every channel of your system. If you use additional amps for the front channels take out the U-shaped
connectors (see p.34). Make the connections shown below to add amplifiers to power your speakers.
Before making or changing the connections, switch off the power and disconnect the power cord from
the AC outlet.
