Although many people might jump into an “add-on” amplifier to power to rear coaxial speakers, a better choice is usually a subwoofer amp/speaker system that supplements the existing 4 speaker system as shown in the adjacent drawing. Such a system provides a surprising improvement in sound quality due to the usually dramatic increase in bass response. The next dramatic step up in performance is with a “multichannel” system that offers more dynamic range in the mids and highs due to higher power p

• Bypass all equipment between radio and amp (e.g., equalizers) directly connecting radio. If noise goes away, signal processor has problem. •Check for signal level “ground loops” - disconnect the outer shield of the RCA cable at one end of the cable (e.g., radio end). If noise goes away, modify cables accordingly. There are voltage differences at the ground connections of the components and these are NOT correctable any other way than such shield cutting or an outboard “ground loop isolator” wh

This equipment generates, uses, and can radiate radio frequency energy, and, if not installed and used in accordance with instructions, may cause harmful interference with radio communications. However, there is no guarantee that radio interference will not occur in particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to contact the dealer or an experienced

This means that if the setting is a 0.3V, it only takes 0.3Volts to drive the amp to full output. (Such a low setting allows for the amp to be easily overdriven and more susceptible to noise so a mid-position is highly recommended for most radios.) CROSSOVER MODE SELECTOR -Depending upon the system design chosen, you need to set the amplifier in the proper “mode” be it LP, Flat, or HP. The low-pass and high-pass frequency settings are explained above. The “Flat” setting simply allows for the amp
