Crown Macro-tech 1200 - Power Amplifier - Used

This used Crown Macro-Tech 1200 is in good working condition but features some cosmetic marks. This unit has been tested in house by experienced engineers, if you have a question about this product please contact us.Sometime labeled Amcron for european models.

Micro Tech amplifiers utilize numerous Crown innovations including grounded bridge and ODEP technologies. Cooling techniques make use of the what is essentially air conditioner technology. Air flows from bottom to top, and front to side. Air flows a short distance across a wide heatsink. This type of air flow provides significantly better cooling than the “wind tunnel” technology used by many other manufacturers. Output transistors are of the metal can type rather than plastic case.

We may have multiple of this unit and conditions of units may vary, before purchase please confirm the unit pictured is the unit for sale. Updated pictures can be provided. If you don't chat with us prior to purchase we can not guarantee you will receive the unit pictured.

This allows for a significantly higher thermal margin for the given voltage and current ratings. All devices used are tested and graded to ensure maximum reliability. Another electronic technique used is negative feedback. Almost all power amplifiers utilize negative feedback to control gain and provide stability, but Crown uses multiple nested feedback loops for maximum stability and greatly improved damping. Most Crown amplifiers have damping in excess of 1000 in the bass frequency range. This feedback, along with our compensation and ultra-low distortion output topology, make Crown amplifiers superior.

Crown Macro-Tech 1200 Features

Patented ODEP (Output Device Emulation Protection) circuitry compensates for overheating and overload
IOC (Input/Output Comparator) circuitry immediately indicates any distortion exceeding 0.05% giving dynamic proof of performance
Two mono modes (Bridge-Mono and Parallel-Mono) for driving a wide range of load impedances and cable lengths
Full protection against shorted outputs, open circuits, mismatched loads, general overheating, high frequency overloads. Loudspeaker protection against low frequency and DC output.
Plug-in PIP card facility
