Martin Audio MA1400 Amplifier

Martin Audio MA1400 Amplifier

Made by Lab.Gruppen

The MA1400 is one of a versatile range of professional power amplifiers designed to meet the increasing demands of both the rental and installation markets whilst remaining cost efficient.
By harnessing a conventional toroidal transformer power supply with the latest semiconductor technology and a proprietary copper cooling system the MA1400 amplifier offers outstanding sonic performance, power and reliability in a shallow (359mm) 2U package.
