You can operate each pair of channels in both stereo and mono (3 channel or tri-
mode) at the same time by using highpass filters (bass blockers) on the higher
frequency stereo channels, and a lowpass filter (coil) on the subwoofers. The
frequencies of the chosen highpass and lowpass filters must not overlap (allow the
mids and highs to play the same music as the subs) or the impedance the amplifier
sees at those frequencies will be cut in half possibly causing it to turn down.

All multi-channel T UBE DR I V E R S are capable of being bridged into a 4-Ohm
mono output without switches or bridging modules.
You can achieve this mono channel by using the left positive (+) speaker connection
and the right negative (-) speaker connection. (Refer to the end panel drawing on
the next page.)
Note: Total bridged impedance of less than 4-ohms may trigger the protection
circuitry causing reduced output and may eventually damage your amplifier.
