Crown MA-5002VZ AE Macro-Tech Anniversary Power Amp

The big daddy out of the commemorative, 60th Anniversary, Limited Edition Power Amps.

Having recently crossed its 60th year and more than two decades of producing the industry-standard Macro-Tech Series of power amplifiers, Crown International is commemorating both milestones with a special, one-time production of the Crown MA-5002VZAE Macro-Tech Anniversary Power Amp.
This amp is the big Daddy of the three Anniversary models. It features a new, visually striking, copper-plated front panel (including handles, knobs, buttons, etc.) and is shipped in a custom wood crate. A special brochure chronicling the history of the product from its initial concept through today will also accompany this amp. It will also include a specification sheet, detailing the actual benchmarked performance of that specific amplifier, signed and numbered by Crown Senior VP of Research Gerald Stanley, whose patented technologies and innovative design philosophies ultimately made the Macro-Tech Series a global success. A very limited quantity of the MA-5002VZ AE amplifiers will be produced - only 600 in total will be available worldwide.

The Crown MA-5002VZ AE Macro-Tech Anniversary Power Amp is modeled after the Macro-Tech Series of Power amps, that are known to fit applications so well, that they are demacro tech emed a classic. The term is synonymous with the Crown Macro-Tech Series of power amplifiers. That product line, and its predecessor Micro-Tech, sparked innovative technologies that provided lower distortion, less thermal stress, higher output power, greater reliability, more power density and amazing audio quality. Like all Crown amps, the defining characteristic of the Macro-Tech Series is sonic accuracy. A tight, rock-solid low end, with smooth, detailed highs and a well-defined midrange. In short, one of the most accurate reproductions, of an audio signal, you've ever heard. Crown puts quality of sound above all else, so their power amplifiers are some of the most coveted in the business.

Controls
Compressor: A three-position back-panel switch is used to control each channels input compressor. The "fast" setting provides an attack time of 4 milliseconds and a release time of 300 milliseconds; the "slow" setting provides an attack time of 12 millise
Enable: A front-panel push button used to turn the amplifier on and off
Input Ground Lift: A two-position back-panel switch located on the PIP2-FXQ used to isolate the input audio signal grounds from the AC (chassis) ground
Level: A front-panel rotary potentiometer for each channel with 31 detents used to control the output level
Loudspeaker Offset Integration: A two-position back-panel switch for each channel used to turn the loudspeaker protection circuitry on and off. The circuitry protects against DC, off-center woofer cone movement, and unwanted subsonic and ultrasonic freque
Sensitivity: A three-position back-panel switch for each channel used to select input sensitivity: 0.775 volts or 1.4 volts for standard 1-kHz power, or a 26 dB voltage gain
Stereo/Mono: A three-position back-panel switch used to select Stereo, Bridge-Mono or Parallel-Mono mode
VZ Mode: A four-position switch for each channel inside the front panel used to control the switching mode of the VZ power supplies
Indicators
Enable: An amber front-panel LED that shows the on/off status of the low-voltage power supply
Signal/IOC: A green front-panel LED for each channel that flashes to show amplifier output. If a channels output waveform differs from its input by 0.05% or more, the indicator flashes brightly to show distortion
ODEP: An amber front panel LED for each channel that shows thermal-dynamic energy reserve. Normally, each ODEP indicator is lit to show available reserve energy. In the rare event that a channel has no reserve, its indicator will dim in proportion to ODEP
ILoad/ILimit: A two-color (green/red) LED for each channel that shows load current and limit current. They glow green to indicate load current flowing out the amplifier, and they turn red when maximum current is being delivered to the load
