Mode Selection
The three-position, recessed Mode Select switch (located on the rear panel) configures the amplifier for
either Stereo. Parallel or Bridged Mono Mode. Amplifiers are factory-configured for Stereo Mode.
Stereo Mode
In Stereo Mode, both channels operate independently, with their input attenuators controlling their
respective levels. Signal at Channel A's input produces output at Channel A's output while signal at Channel
B's input produces output at Channel B's output.

Important !!!
Absolute minimum nominal load Impedance for stereo operation Is:
TAS1100 and TAS4000: 4 Ohm per channel.
TAS1500, TAS1900 and TAS2400: 2 Ohm per channel.
Parallel Mode
When set to Parallel Mode, a signal applied to Channel A's input will be amplified and appear at outputs
of both Channels A&B.

Important !!!
Absolute minimum nominal load Impedance for parallel operation Is:
TAS1100 and TAS4000: 4 Ohm per channel.
TAS1500, TAS1900 and TAS2400: 2 Ohm per channel.
