Bridged mono mode combines the power of both channels into one speaker. This results in twice the
voltage swing, four times the peak power and just less than three times the full power of a single
channel.

an fP 2600 (MLS at 0dB) is 840W. So, the total bridged power into the 8 ohms load will be 2 x 840 =

The MLS switch is located on the rear panel. The MLS (Minimum Load Select) switch offer
impedance matching, so you can drive the fP 2600 into 2 ohms without increased heat loss.
As stated earlier, the fP 2600 can produce 850 watts into both, 2 and 4 ohms. Use lower MLS
(-3dB) when connecting to lower impedance loads as shown in table 1. As can be seen in table 1, the fP
2600 can produce output power in excess of 850 watts.

One way to understand the load
and power from the amplifier's
perspective in bridged mode is
that it is zero voltage at the
centre of the voice-coil
winding. This is because the
coil is driven with positive
voltage at one pole and an
equivalent negative voltage at
the other pole. So, if an 8 ohms
load is connected in bridged
mode, one channel shares one 4
