USING THE CROSSOVER

The following three pages show how the internal crossover can be used to biamp your system. One amplifer plays the lower frequen- cies, while another plays the highs.

The electronic crossover inside the M•2600 splits the frequency band into two ranges, one below the crossover point (LOW OUT) and one above (HIGH OUT). The LOW OUT is available to the amplifier section for powering subwoofers. Both the LOW OUT and the HIGH OUT are switchable to the THRU outputs, for sending line-level signals to the inputs of other amplifiers.

IT’S FREE!

The crossover has been carefully designed to give high quality, no-compromise performance, equal to external crossovers (without the extra cost). It uses a 4th-order Linkwitz-Riley design, with a slope of 24 dB/octave.

LOW OUT

The output level rolls off above the crossover point. By setting the OUTPUT APPLICATION switch to LOW OUT (SUBWOOFER), any speakers attached to the M•2600 will play only the lower frequency range.

By setting the THRU Switch to LOW OUT, this range can be sent to another amplifier via the THRU output jacks.

HIGH OUT

The output level rolls off below the crossover point. The high range is not available to the speaker outputs; it can be sent to another amplifier via the THRU output jacks if you set the THRU switch to HIGH OUT.

The LOW CUT FILTER can be used to reduce the bass level of the speakers attached to the host amplifer.
