BI-AMP OPERATION

For versatility and increased headroom, some users may choose to use an active electronic crossover / processor, such as the Fender PCN-2 or PCN-4, with the system. The electronic crossover takes the place of the internal crossover of the speaker system. The "Normal / Bi-Amp" switch on the back of the cabinet must be set to the "Bi-Amp" position. Always check to ensure the internal/external crossover switch which selects passive or biamp operation is in the correct position prior to use. Failure to do so may damage the speakers. A typical set-up of a bi-amp configuration is shown at right.

For those situations requiring a subwoofer, Mk III loudspeakers can still be used if a three-way electronic crossover is used. An example of this configuration is shown on the next page.

It is strongly recommended that a fourth-order "Linkwitz-Riley" or a digital FIR fourth-order active crossover be used. The crossover frequency, for both the 1225 Mk III / 1226 Mk III, should be set at approximately 2200 Hz, the 1211 Mk III should be set at approximately 1200 Hz. Since the output sensitivity of the compression driver is higher than that of the woofer, the high frequency output of the system must be decreased at either the crossover (if such a control is provided) or at the power amplifier(s) that are used for the high frequencies.

CAUTION: Be sure to connect the high frequencies and low frequencies to their correct inputs indicated on the back of the speaker cabinets.

CARPET COVERING CARE

Mk III Series cabinets are covered in a tough, black indoor/outdoor synthetic carpet for long life and lasting good looks. To clean the carpet covering, use a sponge and a light soapy water solution to wipe away any smudges or

dirt. For stubborn stains, a slightly more concentrated soapy solution or carpet shampoo with a brush may be used. Avoid spilling liquids on the input panel, grille and speakers.
