Note for Bench Test
NOTE: Channel B is always polarity reversed on the input, but polarity compensated by
feeding the minus pin on the Channel B output with the output voltage. Channel A output is
connected in normal polarity mode. By having channels A and B operating in opposite
polarity, the energy storage in the power supply is more efficient. This is significant for
signals below 100Hz (sub-bass, etc.) and improves the power bandwidth. Be sure to use
balanced inputs on all measurement equipment (also oscilloscope probes) if you are bench
testing.

2.2.2 Tandem Mode
In tandem mode, both channels’ inputs are linked and receive the same signal. The tandem
mode is active if the Link switches are in the ‘On’ position. Both level attenuators are
active, allowing you to set different levels for each channel. Note that only the inputs are
connected in parallel. This is NOT a parallel output mode. Never connect either output
terminal to ground or in parallel.
You can use the remaining input connectors to carry signal to other amps. This is called
‘Daisy-chaining’.
NOTE: Always turn off the Link switch when using the amplifier for Bi-amping.
