All multi-channel TUBE DRIVERS 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. You can bridge the front or rear channels in the same way. (Refer to the end panel drawing on page 10.)

Note:Total bridged impedance of less than 4-ohms may trigger the protection circuitry causing reduced output and may eventually damage your amplifier.

M i x e d M o n o O u t p u t

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 the protection circuit to activate.
