Introduction
Thank you for purchasing an MTX Audio Hi-Performance amplifier. Proper installation matched with MTX speak-
ers and subwoofers provide superior sound and performance for endless hours of waking the neighbors, slam-
min' your friends or flat out stomping wanna-be players. Congrats and enjoy the ultimate audio experience with
MTX !

Features :
• XTC - (Xtant Technology Cooling) - A regulated thermal intercooler, injecting cool air through internal heat
sinks. Fan speed is load dependent and continuously variable, sampling the temperature of the heat sink and
transformers for maximum reliability. Intercooler exhaust is strategically placed to chill transformers and main-
tain exceptional performance at any volume level. (Cool eh ? An Amp with an Intercooler ! )
• Pure N-Channel Design - Patent N°: US05631608 and N°: US05783970 - MTX amplifiers incorporate N-
Channel MOSFETs on both the positive and negative circuits of the output stage (PURE N-Channel Design). No
additional circuits are needed to compensate for inefficient designs like P-Channel MOSFETs. Both the positive
and negative circuits have equal usable power ratings. Genuine Genius...Yea we know...
• EAF Technology (Efficient Auto Former) - Patent N°: US05598325 - Our Transformers are "Auto Formers"
which allows us to use smaller magnetics (-30% to -50%) yielding increased efficiency. Turn ratios are improved
due to series connections between the primary and secondary taps meaning MORE Power !
• Smart Engage™ Technology - Patent N°: US06556683 - The amp switches on and off automatically when
connected with high level inputs. No need for a remote turn on wire from under the dashboard. No need to
remove the head unit. Thanks MTX !
• Bi-Level Inputs - High level inputs (Speaker cables) and line level inputs (RCA) utilize the same RCA type input
connections on the amp.
• 21mm 2 Power Connectors - For maximum voltage and current transfer, MTX mono blocks are equipped with
MASSIVE 21mm 2 power connectors. It takes BIG power to make BIG power!
