MA – MACRO AMPLIFIERS

The new MA series, available in 4ch, 2ch and mono are already ground breakers.
Fully specced advanced crossovers, small footprint, versatility & massive power output sets them apart from the rest.
Oh, did we mention they are also marine capable**? Thus powersports, ATV’s & Marine applications have no excuses for not being B2 audio.

The 1000.2 refers to 1000 watts divided into 2 channels, making it a key component in any installation, either large or small.
The 1000.4 is the same 1000 watts power as the 2 channel, but divided into 4 channels.
Both has the ability to bridge the channels, the output is sufficient to forcefully control our EL, IS & HN subwoofers.
Should you require to go beyond loud, both of the multi-channels are a natural component in any full range setup.

MA2000.1 is a mono as the name implies, with an entire 2000 watts at 1 ohm performance is not what’s lacking.
But if you need even more, the 2000.1 is linkable with another unit, that’s 4000 watts at your disposal!
Should that be a bit too much, the latest addition, The MA1200.1 has the same dimensions as the MA1000.4.
Nearly the same power output, but added into a single channel (>1000 watts at 1 ohm).

MA6000.1

If the other Macro Amplifiers didn’t convince you of their abilities, the MA6000.1 puts any doubt to shame.
It’s key features are not only the full range design, but also the excessive capacitor bank providing enough oomph for any subwoofer driven by this amplifier.

With the full range design, you can also use it for pro audio midranges, should you be crazy enough to connect 20 pairs of them to the speaker terminals.
With a true 1 ohm stability, the wiring options are versatile. Other amplifiers with the same full bridge technology usually offer 1 & 2 ohm models, but none are fond of a static 1 ohm load. Besides most of those don’t offer any real advantage beyond compact size, merely due to part count is kept to a minimum, which in turn offers less impressive performance if the amplifier is intended for subwoofers.

Our take was therefore to take best of both worlds, utilizing our reveered & proven Class D amplifiers, scaling them down a bit, but still offering amazing power, full range abilities and proper power terminals. At B2 audio we have always said it takes power to make power, therefore we chose oversized dual 0 GA  terminals. We don’t believe in defying Ohms law, so it makes no sense in opting for a single 0 GA terminal when the amplifier supposedly provides 8000 watts or more. Should you be in need of an amplifer that is not an either or, but a worthy opponent to any 1 ohm stable unit, The 7500 watts handed out by the MA6000.1 makes it a serious contender.

Size

Space will nearly never be an obstacle, as these amplifiers will suit any application. Efficiency is never a problem due to the full range class D design with up to 88% efficiency.
Advanced crossovers featuring both low pass, high pass and band pass (multi-channels), all with our “ACCU8” function (individal click position for corresponding frequencies), a feature also implemented in both the 1200.1, the 2000.1 & the MA6000.1

*In order to get the full power output of the amplifier, it is crucial that your electical system is correctly (over) dimensioned. Failure to upgrading will constrain the power output & lower the efficiency which can cause damage to the amplifier &  void the warranty.
This also includes ohm loads below of what is written in the manual. Do take your time and read the manual thoroughly prior to installing! **Marine capable products are not to be subjected directly to water, but has the ability of being functional in humid conditions.
