ALTERNATE SYSTEM CONFIGURATIONS (contd.)
BIWIRING AT THE AMPLIFIER
Biwiring consists of the simple act of running two sets of speaker cables from the designated channel's speaker output to
each speaker and, observing correct polarity, connecting one set to the "HI" terminal and the other to the 10" terminal.
A speaker with a 'biwire' option provides two inputs on the rear panel of each speaker enclosure, or internally on the
speaker's crossover circuit board. There is usually one input for "HI" frequencies, and one for the 10" frequencies, For
normal operation, these inputs will likely be bridged with some type of jumper configuration. Usually, it is a matter of
removing these jumpers to allow biwiring. [See Fig. 3(a)]
The instruction manual enclosed with the speaker will usually guide you through the connection process.
AVOID SPEAKER/AMPLIFIER DAMAGE
1. OBSERVANCE OF POLARITY IS ESSENTIAL. DOUBLE-CHECK CONNECTIONS BEFORE TURNING THE
AMPLIFIER ON. THE AMPLIFIER CAN BE DAMAGED IF POLARITIES ARE INCORRECT.
2. DAMAGE CAN OCCUR TO YOUR SPEAKERS IF THE POWER RATING OF EACH INDIVIDUAL DRIVER IS
EXCEEDED BY THE AMPLIFIER.
- ENSURE THAT ALL THE DRIVERS IN YOUR SPEAKER SYSTEM ARE CAPABLE OF HANDLING NOT ONLY
THE POWER BEING DELIVERED BY THE AMPLIFIERS), BUT THE ENERGY THAT IS LIKELY TO BE
GENERATED DURING STRONG PASSAGES.
