Protection
Macro-Tech amplifiers are protected against shorted, open or mismatched loads; overloaded power supplies; excessive temperature; chain destruction phenomena; input overload damage; and high-frequency blowups. They also protect loudspeakers from input/output DC and turn-on/turn-off transients.

If unreasonable operating conditions occur, the patented ODEP circuitry will proportionally limit the drive level to protect the output transistor stages, particularly in the case of elevated temperature. Transformer overheating will result in a temporary shutdown of the affected channel; when it has cooled to a safe temperature, the transformer will automatically reset itself. Controlled slew rate voltage amplifiers protect against RF burnouts. And input overload protection is provided by the input compressors and current-limiting resistance at the input.

Turn On: The four second turn-on delay prevents dangerous turn-on transients. It also has "soft start" to avoid tripping the AC circuit breaker by gradually bringing the supplies up to full voltage.
Accessories:Crown PIP and PIP2 modules including IQ-PIP modules.
Construction
Steel chassis with durable black finish, aluminum front panel with Lexan overlay, and specially designed flow-through ventilation from front to back panels.

Cooling: Internal heat sinks with on-demand, proportional forced-air cooling controlled by ODEP. Includes custom heat diffusers and patented circuitry to promote uniform dissipation.

Dimensions: 19-inch (48.3-cm) standard rack mount width (EIA RS-310-B), 5.25-inch (13.3-cm) height, 15.875-inch (40.3-cm) depth behind mounting surface, and 2.875 inches (7.3 cm) in front of mounting surface. Allow 3 inches (7.6 cm) behind the back-panel for adequate air flow.

Crown's Three Year, Full, No-Fault Warranty

Crown offers a Three Year, Full, No-Fault Warranty for every new Crown amplifieran unsurpassed industry standard. With this unprecedented No-Fault protection, your new Crown amplifier is warranted to meet or exceed original specifications for the first three years of ownership. During this time, if your amplifier fails, or does not perform to original specifications, it will be repaired or replaced at our expense. About the only things not covered by this warranty are those losses normally covered by insurance and intentional abuse. And the coverage is transferable should you sell your amplifier.

The Macro-Tech 02 Difference
The Crown Macro-Tech 02 Series amps are enchanced versions of the Macro-Tech line. They offer the same features and performance of the original Macro-Techs while delivering key added benefits that continue to expand the versatility of this distinct product line. Here are a few examples:

Enhanced PIP2(TM) (Programmable Input Processor) connector accepts new accessory modules that tailor the amplifier for specific applications. Balanced XLR and 1/4-inch phone jacks for each channel on the standard PIP-FXQ module.. Full Protection from shorted, open and mismatched loads, general over-heating, DC, high-frequency overloads, and full internal fault protection are provided by our latest protection scheme: "Quad-Mute."

The Macro-Tech VZ Series represents the latest breakthrough in Crown's unending quest to deliver the most power in the smallest package.
The Macro-Tech 3600VZ packs 3,600 watts into a mere 3.5 inches of vertical rack space. The Macro-Tech 5002VZ packs an incredible 5,000 watts into little more than 5 inches of vertical rack space. Quite simply, that's more watts per-cubic-inch than any other amplifier.
Our patented variable impedance (VZ) technology permits the Macro-Tech 3600VZ and the Macro-Tech 5002VZ to dynamically adapt to both signal and load requirements in real time. This provides the best power match to the widest range of loads. Our innovative technology also permits us to pack large amounts of power into a compact package while achieving ultra-low distortion and without generating excessive heat.

Because they're Macro-Techs, both VZ amplifiers provide all the features found in other Macro-Tech amplifiers, including separate high-voltage power supplies, detented controls, P.I.P. expandability and comprehensive status indicators.

The Macro-Tech 5002VZ includes a number of additional features which expands its power and versatility. This includes additional user control over the VZ power supply which allows you to easily set the amplifier for maximum efficiency with your load. It's just another example of how we engineer practical solutions for real-world conditions. The Macro-Tech 5000VZ's universal power supply also allows it to be adapted quickly and easily to available voltages around the world.

With all these features, the Macro-Tech 3600VZ and 5002VZ are two of the best values in amplifiers today, with the highest power for their size, weight and price.

Our unique Macro-Tech 24x6 and 36x12 provide practical solutions to biamplified system applications such as stage monitors. Each amp features a high- and medium-power channel in a single, low-profile unit. Both amps have separate power supplies which allow each channel to be treated as its own amplifier. Providing tremendous power to your bass cabinets, channel 1 of the Macro-Tech 24x6 has the same power and specifications as our Macro-Tech 2402, while the Macro-Tech 36x12 has the same power as our Macro-Tech 3600VZ. Channel 2 of each amp drives horns and other high-frequency transducers with the power of the Macro-Tech 602 and 1202 respectively.

Ultra-Low Distortion: Crown's patented grounded bridgeTM circuitry generates incredible voltage swings with ultra-low distortion and superior reliability.

VZ Power Supply Technology: The Macro-Tech 3600VZ and 5002VZ use patented power-supply technology which provides enormous power density and an optimum power match with a wide range of loads.

Current Indicator: (Macro-Tech 5002VZ only) Cutting edge current flow/current limit (ILOAD/ILIMIT) indicators tell you if current is flowing to the loads, and if the loads demand more current than the amplifier can deliver.

On-Board Compressors: (Macro-Tech 5002VZ only) Each channel has a custom compressor that reduces peak signal levels during input overload and output clipping. The compressors can be set for fast or slow operation, or turned off for output clipping.

Loudspeaker Offset Integration (LOI): (Macro-Tech 5002VZ only) Each channel has a high-performance loudspeaker protection circuit that compensates for DC offset to protect woofers, and filters ultrasonic frequencies to protect tweeters.

ODEP(R) Protection: Patented Output Device Emulation Protection (ODEP) protects the amplifier and keeps the show going under adverse conditions that cause lesser amplifiers to fail. Front panel indicators show each channel's ODEP status. Several PIPTM modules also provide powerful ODEP-driven features.

Distortion Indicator: Advanced Input/Output Comparator (IOC(R)) alerts you if the amplifier causes any distortion of 0.05% or more.

PIP compatibility: Accommodates Programmable Input Processor (PIP) accessories that are used to customize the amplifier for specific applications. MA 02-Series amps are PIP2 compatible.

Selectable Mono Modes: (Does not apply to Macro-Tech 24x6 and 36x12) Bridge-Mono mode provides double output voltage and Parallel-Mono mode provides double output current from a single channel.

Unique Dual-Level Design: (Macro-Tech 24x6 and 36x12 only) Each channel has a different power level for maximum amplifier utilization in biamplified and triamplified systems.
Selectable Sensitivities: Choose from three input sensitivities: 0.775 volts or 1.4 volts for full rated power into 8 Ω, or a voltage gain of 26 dB.
Detented Level Controls: Detented level controls make it easy to set and reset precise levels.

No-Fault Warranty: Crown's exceptional Three-Year, No-Fault, Full Warranty even covers round-trip shipping, and can be extended up to six years in the U.S.A.1
THX Approved: (Macro-Tech 602, 1202, 2402 and 5002VZ only) Lucasfilm(R) approved for THX(R) sound system installations.
