AMH

Congratulations on choosing Australian Monitor for your professional ampliﬁcation requirements.

The design of our new AMH Series Audio Power Ampliﬁers embraces all the aspects of a well designed ampliﬁer. The visual design, mechanical, electrical and sonic parameters, along with our dedicated manufacturing process, have all been optimized to provide a professional tool that exhibits quality, reliability and longevity.

The new AMH Series ampliﬁers are 2 unit (3.5”) high, 19” wide, rack mountable units. Each channel of the ampliﬁer comprises a balanced active input with a buffered attenuator driving a differential class A drive stage which in turn drives a fan-cooled, class AB, output stage conﬁgured as an emitter follower. The ampliﬁer operates from a high current-capable Class H dual Rail switched mode power supply.

These ampliﬁers have been speciﬁcally designed to deliver their high power output with minimal distortion, and provide the critical degree of control required by your speakers, at high duty cycles for extended periods.
