Peavey TKO 65

BI-AMPING THE TKO™ 65
Many bassists and keyboard players today utilize a technique called bi-amping to increase the efficiency
(performance) of their amplification systems, This can be accomplished with the TKO™ 65, one external power
amplifier, one additional speaker and enclosure, and a device known as a crossover. The crossover, such as
Peavey's ECM™ (Electronic Crossover Mainframe) and PL™ Series plug in crossover modules, is the device
used to divide the instrument's signal into two separate signals: low frequencies and high frequencies.
To bi-amp the TKO" 65, use a high quality, shielded patch cord and make the connection fromthe preamp
output to the crossover device input. If the TKO" 65 is to be used for the high frequency section, use another
high quality, shielded patch cord and make the connection from the crossover's high output to the TKO™ 65's
power amp input. The low frequency output of the crossover should then be connected to an external power
amp (Peavey Mode! M-3000" or XC-400" recommended) and the output of the power amp connected to the
speaker system with a high quality, unshielded patch cord. NOTE: IF YOU ARE NOT FAMILIAR WITH THIS
TECHNIQUE, CONSULT YOUR AUTHORIZED PEAVEY DEALER OR THE PEAVEY FACTORY TO OBTAIN
PROPER CROSSOVER POINTS AND OTHER PERTINENT INFORMATION FOR YOUR BI-AMP SYSTEM.
