AMP SERIE
S
In other words, a signal connected to input A is only treated by
channel A of the amplifier and only fed to output A and a signal
connected to input B is only treated by channel B of the amplifier and
only fed to output B.
B) BRIDGE (except AMP 2.4)
With the BRIDGE setting signal is amplified by the two sections
(A&B) of the amplifier
summed together. In other words the signal
connected to input A is:
1) amplified by both the amplification sections summed together;
2) fed to a single output (BRIDGE).
The characteristic of this setting consists in the fact that there is
a signal fed out with double the power and rated impedance (see
é TECHNICAL SPECIFICATIONS).
