Bridged Mono Mode
Bridged Mono Mode straps both amplifier channels together to make a very powerful, single-channel
monaural amplifier. One channel "pushes" and the other "pulls" equally, doubling the power over that of
channel alone. Signal is applied to the Channel A input only. Both attenuators are used to control signal
level; in addition, both must be adjusted to the same setting. Only channel A input may be used
.
Use extreme caution when operating the amplifier In Bridged Mono Mode. Never ground either side of
the speaker cable when the amplifier Is in Bridged Mono Mode; both sides are "hot. "If an output patch
panel is used, all connections must be Isolated from each other and from the panel
.

Important!!!
Absolute minimum nominal load Impedance for bridge operation Is:
TAS1100 and TAS4000:
8 Ohm .
TAS1500, TAS1900 and TAS2400: 4 Ohm.
Connecting amplifier outputs to oscilloscopes or other test equipment while the
amplifier is in bridged mode may damage both the amplifier and test equipment!
