Macro-Tech MA-24X6 & 36X12 Power Amplifiers

1 Welcome

Congratulations on your purchase of a Macro- Tech ® dual level professional power amplifier. Your amplifier has a separate high-power and medium-power channel, making it ideal for biamplified systems. The Macro-Tech 24x6 combines one channel of a Macro-Tech 2400 with one channel of a Macro-Tech 600. The Macro-Tech 36x12 combines one channel of a Macro-Tech 3600VZ with one channel of a Macro-Tech 1200. And because each model has a separate power supply for each channel, each channel can be treated as a separate power amplifier.

Because it’s a Macro-Tech, you have the added benefit of PIP ™ compatibility for access to custom input modules and ODEP ® protection to keep the show going long after other amplifi- ers would fail.

Modern power amplifiers are sophisticated pieces of engineering capable of producing extremely high power levels. They must be treated with respect and correctly installed if they are to provide the many years of reliable service for which they were designed.

In addition, MA-24X6 and MA-36X12 amplifi- ers include a number of features which require some explanation before they can be used to their maximum advantage.

Please take the time to study this manual so that you can obtain the best possible service from your amplifier.

1.1 Features

Crown’s Grounded Bridge™ design deliv- ers incredible voltage swings without using stressful output transistor configura- tions like conventional amplifiers. The results are lower distortion and superior reliability.

Patented ODEP (Output Device Emulation Protection) circuitry compensates for overheating and overload to keep the amplifier working long after others would fail.

IOC ® (Input/Output Comparator) circuitry immediately alerts of any distortion exceeding 0.05%, providing dynamic proof of distortion-free performance.

PIP connector accepts accessories that tai- lor the amplifier to suit specific applica- tions.

Very low harmonic and intermodulation distortion give the best dynamic transfer function in the industry.

High damping factor provides superior control over low frequency drivers for a clean, accurate low end.

Full protection against shorted outputs, open circuits, DC, mismatched loads, gen- eral overheating, high frequency overloads and internal faults.

Extra rugged, extruded aluminum front panel with ODEP and Signal Presence/IOC indicators for each channel, as well as an Enable indicator.

Macro-Tech 36x12: Articulated VZ power supply for Channel 1 (3600) provides the best power matching to your load.

Efficient heat sinks and forced air cooling prevent overheating and prolong compo- nent life.

Balanced inputs with three-position sensi- tivity switch and adjustable front panel level controls.

5-way binding post outputs provide versa- tile connection.

Mounts in a standard 19-inch (48.3-cm) equipment rack (units can also be stacked).

Three Year “No-Fault” Full Warranty com- pletely protects your investment and guar- antees its specifications.
