DESIGN FEATURES

The MC-300 isconservatively rated at 300 watts into4ohms. This power can be divided into four channels (4x75 watts), three channels (2x75 watts. 1x150), two channels (2x150 watts). The design topology utilizes multiple Darlington out- put devices with a total capability of 1200 watts. With such re- serves and no current limiting, the MC-300 operates without strain even at maximum output. Power, ground, and speaker cnnnectors are rated to handle up to 60 amps and up to 8 gauge wire.

To provide lull circuit protection necessary for an amplifier thispowerful, theMC~300incorporatesauniquedual”smat~ power supply that works silently and effectively to prevent nverheating without the need for a fan. Should the ampllfler begin to overheat, the power supply slightly reduces output power, which allows the unit to run much cooler. Once the amplifier returns to normal operating temperature. full output capacity is then restored. The entire process is automatic and inaudible. In the case of an amplifier malfunction, secondary thermostats WIII shut down the ampllfler in a conventional manners To prevent potentially damaging turn- on or turn-off thumps. a pair of relays at the outputs allow the amplifier to fully stabilize before sending the audio signal to the loudspeakers.

An especially useful feature of the MC-300 IS Linear Sub- woofer Extension (LSE). which compensates forthe natural rollofl of most speakers and extends bass as much as one full octave. LSE provides a linear boost of 6 dB/octave, starting at a point which is continuously variable over the range 35-280 Hz. A subsonic filter attenuates the signal below 20 Hz.

Orfly prerrfium parts are used 111 the MC.300. such as metal film resistors, gold-plated input connectors, and immersible sealed potentiometers. The case is equipped with generous heat sinks. Input sensitivity is adjustable to match any tuner! deck, the MC-300 can even be interfaced with OEM speaker level signals.

INSTALLATION

Proper installation and adjustment will reward you with reliable operation and optimum performance. Automotive_ sound system installations can be tricky. especially for firs timers. For this reason, you may want to consider using a professional installer who has the tools and, more impor- tantly, the experience, to do the right job. If you decide to install your equipment yourself, we hope that this manual will serve as a helpful guide.

LOCATION AND MOUNTING

The first step in irrstallation is thorough planning. Choose the location for your amplifier carefully. The amplifier should be located in either the passenger compartment or the trunk, never in the engine compartment or in any outside location exposed to din and moisture. Adequate ventilation is impor- tant. allow enough space so that air can circulate around the heat sinks.

Make sure that the installed amplifier will not interfere with normal operation of the car. It is best not to locate the ampkfier near your vehicle antenna, since the switching powersupplycan interfere with AM reception. Your amplifier should be mounted firrrfly to your car’s sheet metal with the four screws provided. USC your amplifier as a template for making pencil marks where you intend to drill. (Make sure thatthelocationyouareplanning todrillthroughisfreeofany obstacles such as wiring or gas tanks.)

It’s a good Idea to bench test your system before mounting* thecomponents. If you have a 12.voftpowersource. you can connect and test all components outside the car. Or, you can connecttheminsidethevehiclepriortofinal mountings Either way, connect the components exactly as you intend to in the final installation; make all power connections last; test the system; then disconnect all power until the final installation

is complete.

WIRING

Determine how your vehicle’s wiring is laid out. Keep all wiring inside the car. Good standard audio practice suggests keeping signal wires short and away from wires carrying power. Wires can be run under carpet. If you drill a new passage hole through metal, make sure that all burrs have been filed away to prevent scraping; use grommets where needed. All wires should be hidden: an exposed wire can inadvertently be pulled, causing disconnection or shorting. Wires should never be under tension or subject to moisture. Use cable ties to bundle excess wire.
