Description
MTX XTHUNDER125.4
500-WATT RMS 4-CHANNEL CLASS A/B AMPLIFIER
What’s Under the Hood?
We start by using a class A/B amplifier topology to maximize power efficiency while delivering unmatched sound quality. This is all built on a dual sided circuit board with oversized copper traces that maximize electrical flow and minimize power loss before it gets to your speakers. Components are installed using surface mount technology making the circuit incredibly durable and vibration resistant allowing them to survive even when used in big bass systems.
Additional heat management is handled by the top cover which functions as a large surface area heat sink. The chassis also includes removable side covers that create a stealth look when installed but also allow for easy access to connections and settings after mounting.
FEATURES
• Class A/B Topology - Delivers Excellent Sound Quality
• Variable Bass Boost - Allows you to boost your bass output by up to 18dB @45Hz
• Low Profile Design - Allows for Installation Anywhere
• Cast Aluminum Top Cover - Efficiently Dissipates Heat
• Variable Butterworth Crossover - a 12dB/Oct crossover that allows you to set the frequency your speakers will play down or up to
• Triple Protection Circuitry - Thermal, DC Offset, and Short Circuit Protection circuitry ensures the amplifier will protect itself in the event of a problem
