    Icon32 Mono-block amplifers fact and fiction

    A guy I know who's been in the business for a while told me to be careful while shopping for ''mono-block'' amps.

    He made it seem as if even though some amplifiers that claim to be mono-block, by the process of the way they work, they are not able capable of
    performing single channel amplification as a supposed "proper" mono-block amplifier would. What do you suppose he meant. By this I could only assume he was referring to higher end models but, are there amps which claim to be mono-blocks which by process are in fact employing methods to replicate/reproduce the actual process a true single channel amplifier would (such as a work around). For the purpose of clarification by what specifications are ''true'' mono-block amps defined. Is there anything specific I should look to avoid or look for towards the future purchase of amps that say they are mono-block amplifiers. Thanks. Also I apologize for the misleading info I had given on a previous thread, I had assumed by definition a true mono-block amp had to be 1 ohm stable but it's more likely it was spoken to me in relation to my current system.

    All it's going to take to be a true mono amp is if it's one channel. Mono being one. And being 1 ohm stable or 2 ohm stable has nothing to do with it being a mono. And just because something is 1 ohm stable means nothing. A lot of nice mono amps are 2 ohm stable and nice. Take Kicker for instance or Alpine. Most of their amps are only 2 ohm stable but solid amps none the less.

    That's not in question. The question is there some process some amplifiers that claim to be mono-block try to replicate the actual single channel
    process by walk arounds etc (opposed to an amp which is built to handle single channel processing properly) as if they were offering the real thing.

    Some two channels can bridge to one channel but they are not mono blocks. A mono block is a amp with one channel. Why is this so hard to understand?

    op are u sure he is not refering to mono and class d? ive seen some newer style 2 channel amps are class d and iirc they are more efficent than the traditional class ab but they are also not a clean power wise .

    The good full range class Ds are good. JL HDs, ZED, Alpine PDX, Hertz to name a few. I feel something is missing but most audiophiles love them

    Actually he was specifically referring to a Class D mono and 1 ohm impedance, but it was in relation to my current system setup.

    i was not trying to put down the quality of those amps just saying the truth . older style class ab were power hogs but they were very clean like .005 for example the us amps or the older style rockford fosgate . the point was a mono amp can be a class d but a class d can also be a multichannel

    Class D are more efficient at lower ohm loads than Class AB, but at high ohm loads that isnt true. Also Class D amps sound just as good as Class AB if you buy a quality Class D amp.

    Re: Mono-block amplifers fact and fiction

    well, like most have said a mono amp is not defined by what ohm load its stable @ but rather how many channels. also a mono amp will not have a hpf and will have a subsonic filter as these amps are used for driving a sub . so yes a mono amp can be a class d and 1 ohm stable and 2 ohm stable . i feel you are missing the point ur guy is trying to make a class d mono is actually a more efficent amp and can be stable @ lower ohm loads so if u were to run a 3000 rms mono compaired to a 3000 watt class ab it would be a big difference .
