To truly understand how our Pure N-Channel Technology improves the sound of our amplifiers, it helps to understand how the amplifier's output stage works. Even if you don't know much about audio, you've probably already figured out how a speaker makes sound - the cone travels back and forth to move air. It's the job of the amplifier's output stage to control the speaker's movement by managing the power applied to the speaker. This is accomplished by the positive and negative circuits located on the amplifier's output stage. The positive circuit pushes the speaker and the negative circuit pulls the speaker (easy so far, huh?).  Within these positive and negative circuits are MOSFET transistors. These MOSFETs control the alternating current traveling to the speaker. Each of the positive and negative circuits use a dedicated MOSFET to distribute the power to the speaker. A common approach is to use an N-Channel MOSFET for positive (to push the speaker) and a P-Channel MOSFET for negative (to pull the speaker back). SEEMS like a good idea. But, our engineering guys (who study circuits for fun instead of doing real people things like going to movies) identified several problems with this scenario.  First, in many cases, the P-Channel MOSFETs operate slower than the N-Channel MOSFETs. This means that engineers have to add circuits to compensate for the difference. When you have to add circuits to compensate for inadequacies in your components, that's not smart design. And, even worse, in many cases, the P-Channel MOSFETs are more highly resistant devices (meaning they waste more power as heat, instead of using it to drive the speaker). What this means is that the P-Channel MOSFETs can have a much lower USABLE power rating than N-Channel MOSFETs. MTX Audio is one step ahead of the game with our Pure N-Channel Design amplifiers. We design our amplifiers to use only N-Channel MOSFETs on both the positive and negative circuits of the output stage (PURE N-Channel Design). So, no additional circuits are needed to compensate for the shortcomings of the P-Channel MOSFETs. And, both the positive and negative circuits have equal Usable Power Ratings.

Pure N-Channel Design:

1. It's more linear, so the speaker is better controlled.
2. The signal travels through fewer parts so the signal-to-noise ratio is enhanced.
3. Power rating is better, so the amplifier runs louder, longer.

For those of you who have been reading this carefully, you're probably saying, "Well if this Pure N-Channel thing is so great, why doesn't everybody do it?" BECAUSE IT'S HARDER. It's a circuit that has to be more carefully engineered to make it work properly - something we've been doing ever since the first Thunder amp was born in 1995.

Pure N-Channel Design can be found on multi channel amplifiers in the Thunder Elite, RFL, JackHammer and Terminator series

Class D amplifiers are pretty common these days. It seems like everybody has one. Let's discuss the common approach. Amplifiers that use Class D technology are switching amplifiers. These amplifiers feature MOSFET transistors that operate as a switch and are used to manage the power applied to the speaker. The controlled switching power distribution creates a square wave known as Pulse Width Modulation. High frequency energy is generated from this square wave and is commonly concentrated at one point that must be filtered from the audio path of the amp. Harmonics from this concentrated high frequency energy travel into the radio frequency range, and can cause interference with the radio's reception or be picked up by the audio system's ground. That means NOISE. MTX changed the rules with our innovative, new Adaptive Class D Technology. With our approach, the amplifier's switching energy is constantly changing and is moved away from FM radio frequency ranges as the amplifier's load and output increases. This ensures that the harmonics do not interfere with the radio's reception and are not picked up by the audio system's ground. This improves the amplifier's overall signal-to-noise ratio, and eliminates interference that is generated by more common Class D amplifiers. In other words, listeners can enjoy all the clean, musical sounds from the radio without the interfering noise of the Class D amplifier. Technology. What a great thing when you use it right.

Adaptive Class D Technology can be found on many MTX mono block amplifiers including: Thunder Elite, RoadThunder, RFL, and Terminator

Smart Engage Auto Turn On is a technology incorporated into MTX amplifiers that makes them easier to install and easier to use.  Smart Engage allows the amplifier to be installed without the need of running a remote wire from the head unit to the amplifier.  You can tap into the vehicle's speakers anywhere in the vehicle with an RCA connector that has one end of RCA's removed, then run the other RCA connector into the amplifier and once the speaker receives voltage from the head unit, the amplifier will automatically power on.  This is especially convenient if you are adding an amp and sub to your trunk and do not want to mess around with removing the head unit.  You can tap into the rear door or deck speakers and run the RCA to the amplifier.  Add your power and ground wires and your system is ready to rock.
