    Product Description

    The Palmer MACHT 402 is a 19" stereo power amplifier specially designed for guitar applications. It pumps out 200 watts per channel and 400 watts bridged to drive virtually all speaker cabinets. Featuring a highly efficient switch mode power supply and low noise fan the soft start class D design is protected against overvoltage, DC, short circuits and overheating.

    Conventionally named, the channels' Hi and Low controls have been carefully tailored for guitar signals to provide extensive EQ facility, a wide variety of sounds and authentic tube power stage characteristics. In addition, the MACHT 402 sports rumble filtering, LED indicators, a 3-way sensitivity selector, built-in limiter and ground lift switch. With XLR and 6.35 mm inputs as well as Speakon compatible and 6.35 mm output connectors the Palmer MACHT 402 is the ideal power station for guitar preamps, small amps, modelers and even effects pedals.

    Bought to power a rack mount Line 6 Pod Pro X into a Marshall 4x10 cab. Currently only run it in mono "bridged" mode and it works just as I want it. The extra EQ on the amp gives you options to tune your tone for extra "oomph" and I think it'll have enough power to be heard above a loud drummer at a "backline only" gig. And the compact size/low weight is a nice bonus. And it looks cool!

    This amp is really good If you have a modelling device (I have a Headrush Gigboard) this is perfect Plenty of power - the way to go if you have Headrush, Klemper etc I agree with Lee that the future of guitar amplification is this kind of product - I use it with 2 old Electrovoice Stage 200 PA speakers - wow what a sound Highly recommended
