Here’s a special surprise: If you bought the M•2600 amplifier to power a subwoofer system, you just saved yourself the cost of a crossover! The M•2600 amp has an active crossover built in. The amplifier can play the frequencies below the crossover point set with the CROSSOVER switch .

Crossover settings.
Here’s how to configure it:
1.Turn the M•2600’s POWER off.
2.Set the OUTPUT APPLICATION switch to LOW OUT (SUBWOOFER).
3.Select a crossover point, via the CROSS- OVER switch : At 120Hz, you’ll get the low
4.Make sure the LOW CUT FILTER is set to OFF or nearly OFF. If it is turned up above the crossover frequency, the output from the amplifier will be greatly diminished.
5.Set the AMP MODE to either STEREO, MONO, or BRIDGED, depending on your application. These three modes operate as usual with LOW OUT (SUBWOOFER) activated, except the speakers just get the lower frequencies.
6.Connect your cords and speaker cables as required (see the examples on pages
7.Turn the M•2600’s POWER on. Woof!
If you want to use a second M•2600 or an M•1400i to reproduce the rest of the audio range, follow this procedure:
1.Connect the THRU jacks on the first subwoofer amplifier to the INPUT
jacks on the second amplifier.
2.Set the THRU switch on the first subwoofer amplifier to the HIGH OUT position.
3.With POWER off, set the OUTPUT APPLICA-
TION switch on the second amplifier to
FULL RANGE (LIMITER either ON or OFF).
The first amplifier will play the frequency range below the crossover point, and the second amplifier will play the frequency range above it. See the diagrams and further information on pages
