SYSTEM CONFIGURATION #1

Full-Range High-Pass

Full-Range High-Pass Subwoofer

5 Channel Combo (2ch HP + 3ch passive Multi-Mode)

The multi-mode system is a “poor-man’s” satellite/subwoofer system. This amplifier is able to drive speakers in stereo mode and at the same time drive low frequencies to a dedicated

subwoofer speaker. By inserting inductors (coils) and capacitors, the result is an inexpensive solution to generating a ‘5' channel system with a 4 channel amplifier.

Using passive components (coils and capacitors) the installation is simple and performs adequately for most listeners. Such a system will not perform as well as an “active” system because the slow attenuation (roll-off) of the frequency response resulting in a moderate amount of over-lapping of the sound spectrum between the satellites and subwoofers. It is important to remember that although surprisingly pleasant performance is achieved, this is a compromise system and will NOT perform as well as a dedicated 5 channel system with electronic crossovers.

SYSTEM CONFIGURATION #2

Full-Range Full-Range

Full-Range Full-Range

4 Channel (Full-Range,HP)

For many listeners, they need only slightly higher system loudness and/or music dynamic range without the amplifier going into distortion. By simply adding additional power to the speakers this can be achieved in many installations. BUT, the speakers must be able to handle this additional power without damage.

Such installations are most common with listeners who only need systems that can play moderately loud. Also, this consumer is often a person who simply cannot, or will not, accept additional amplifiers or speakers in the vehicle. Such systems will not be able to perform as well as audio systems with additional speakers and amps, but this is often an accepted trade-off for this consumers.
