Modes: Stereo/Parallel/Bridge; Speaker Impedance - Yamaha P4500 Manual De Instrucciones

Modes: STEREO/PARALLEL/BRIDGE

STEREO mode
In this mode, channels A and B operate independently
(as a conventional stereo amp).
The CHANNEL A input signal will be output from the
CHANNEL A output jacks, and the CHANNEL B input
signal will be output from the CHANNEL B output
jacks.
PARALLEL mode
In this mode, the CHANNEL A input signal will be
output from the output jacks of both channels A and B.
The CHANNEL B input jack is not used. The (channel)
A and B volumes can be adjusted independently.

SPEAKER IMPEDANCE

In STEREO and PARALLEL modes, the minimum load
(=speaker) impedance is 4Ω. In BRIDGE mode it is 8Ω.
Make sure that the impedance does not fall below this
specified impedance.
