IRD Audio's New "Giant Killer" HT MB-100 Monoblock Amplifier
For power, looks, build quality and sonic abilities this new monoblock amplifier will rival anything on the market today.
The MB-100 is being compared, by audiophiles, to amplifiers that cost thousands of dollars. This is a robust almost bulletproof no maintenance design for 2ch music or HT applications.
Six of these amplifiers (for 5.1) can be combined to supply the audio for a substantial home theater system and will rival or beat most of the best / expensive HT's amps out there.
We think 6 amps in one box running off one power supply and one power cord is cheating . Many of these all-in-one HT amplifiers do not even meet their own specs. NOT SO with the MB-100
With a IRD Audio MB-100s HT setup you get 6 amps at 23 Lb. per amp (138 Lb. total) and each with it's own 400 Watt power supply. What were saying here is 6 x 400W = 2400 Watts RMS for your HT application. Monoblocks are very easy to install giving the installer more flexibility. A very clean install.
This amp was designed to play loud and clean with only 0.014% THD+N at full continuous power. Music program peaks of more than 240 watts have been measured into 4 ohm speakers. Subs, no problem. Watch a movie and you will BE THERE!
The MB-100 is 6.5"W x 7.0"H x12.8"D and weighs in at 23 Lb, It sounds like a much larger amplifier due to the 400 VA power supply and large 20,000uF reservoir capacitors. The silicone steel shielded low noise toroidal transformer alone weighs in at 9 Lb. This unit was built to easily drive any speaker system.
If you like to play your music loud... make sure your speakers that can handle the MB-100s high output peaks. Instantaneous peaks of 160(8 ohms) -> 240(4 ohms) watts are common.
The MB-100 is dead silent "at full volume" between music content... crystal clear smooth midrange and highs and... the rich bass shakes the building! The frequency response is flat from 7-50KHz. This DC coupled amplifier is quite transparent yet very smooth.
With an 8mm thick machined aluminum front panel, solid aluminum machined feet (w/Butyl rubber inner feet to protect furniture), black nickel finished hardware, side and top wall enclosure thickness of 2mm steel, an easy removable top cover, heavy duty removable power cord and... power to shake your house... you can tell right away that this is no mass produced discount store amplifier.
The MB-100 is a very cost effective method to add the three additional channels required, to a standard stereo system, for home theater applications. An easy upgrade and install.
