Class A/B Topology

A class A/B amplifier uses two groups of transistors and it’s typically thought to be to be the most productive compromise of the two classes put together. A pure class ‘A’ amplifier generally has a huge amount of current flowing through its output transistors and not using a audio signal. A pure class ‘B’ amplifier has no current flowing through its outputs and not using a audio signal. This removes virtually all the crossover distortion that’s conceivable with class ‘B’ amplifiers. A class A/B amplifier is a lot more efficient than a class ‘A’ but without the conceivable distortion of a class ‘B’.

MOSFET Power Supply

Metal–Oxide–Semiconductor Field-Effect Transistor is a transistor used for amplifying or switching electronic signals. We use it in computers, telephones, game consoles, cars, electrical appliances, and in our amplifiers. They’re found in systems where information is processed or stored. A MOSFET is mainly an electrical switch that allows the drift of electrical current. The MOSFET performs its most necessary role in our D Class amplifiers by allowing or preventing the drift of power and creating an efficient amplifier.

Low And High Level Inputs

Low And High Level Inputs

You can get a signal into Phantom series amplifiers two different ways – Low level and High level input. A low level input is measured in voltages. It comes in the type of RCA outputs from the back of your receiver and goes to the RCA inputs on your amplifier. A high level input is measure in wattages. It comes in the form one positive and one negative wire from the back of your receiver to and goes to the input terminal of your amplifier in the same wire form. Low-level (RCA) input wiring is preferred for best audio performance. At all times use a high-quality RCA cable for best audio performance. Note: Do not connect both the high level and low level inputs from your receiver to your amplifier on the same time.

Full Range Monoblock

Full Range Monoblock

With a Full Range Monoblock amplifier you not only have the option to run your subwoofers, but also your speakers. By just a flip of a switch from Low to Full, the PH1500M will change from only offering a low to a whole range of frequencies that you wish to have with the intention to listen to your 2, 3, 4, or 5 way speakers.

Variable Crossover

Variable Crossover

Subwoofers reproduce sound based low range frequencies. This process is known as the crossover effect and occurs since the vast majority of audio systems cannot cover all of the spectrum sufficiently to minimize sound distortion and deal with an appropriate frequency ratio. In terms of our PH1500M amplifier, a variable crossover is offered in order that you, the listener, can be able to set the frequency at which the crossover occurs, thereby setting precise sound specifications on your subwoofer.

Variable Bass Boost

Variable Bass Boost

The difference Bass Boost and Variable Bass Boost is that with Bass Boost you either have extra bass or you don’t. But with Variable Bass Boost you have Keep watch over of exactly how much BASS you wish to have to pump out to your subwoofer(s). You get Variable Bass Boost with the PH1500M Amplifier.
