Macro-Tech Series Power Amplifier - 1565 Watts Per Channel at 4 Ohms
The Crown Macro-Tech Series is the defining standard for amplifier design today. No compromises, no gimmicks. Just brilliant engineering backed by superior manufacturing, support, and an unsurpassed commitment to 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, the most accurate reproduction of an audio signal you've ever heard. And because we put the quality of sound above all else, a Crown is the most coveted amplifier in the business.

Ultra-Low Distortion: Crown's patented Grounded Bridge 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.
Selectable Sensitivities: Choose from three input sensitivities: 0.775 volts or 1.4 volts for full rated power into 8 ohms, 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.
Load Impedance: Rated for 16, 8, 4, and 2 ohm use only. Safe with all types of loads, even reactive ones.
AC Power Requirements: 100 VAC, 50/60 Hz; 120 VAC, 50/60 Hz; and 230 VAC, 50/60 Hz units are available. 230 VAC, 50/60 Hz units can be used with 220 and 240 VAC. All versions draw 90 watts or less at idle. 100 and 120 VAC units can draw up to 30 amps of current; 230 VAC units can draw up to 15 amps.
Frequency Response: 0.1 dB from 20 Hz to 20 kHz at 1 watt.
Phase Response: 10 from 10 Hz to 20 kHz at 1 watt.
Signal-to-Noise Ratio: Greater than 105 dB below rated output (20 Hz to 20 kHz, A-weighted); 100 dB below rated output (20 Hz to 20 kHz, no weighting).
Harmonic Distortion (THD): At rated output, less than 0.05% from 20 Hz to 1 kHz increasing linearly to less than 0.1% at 20 kHz.
IM Distortion (IMD): Less than 0.05% from 368 milliwatts to full rated output.
Damping Factor: Greater than 1,000 from 10 Hz to 400 Hz.
Slew Rate: Greater than 30 volts per microsecond.
Voltage Gain: (At maximum output) 20:1 6% or 26 dB 0.25 dB at +26 dB gain setting, and 124.6:1 6% or 41.9 dB 1.0 dB at 0.775 volt sensitivity.
Enable: A front panel push button used to turn the amplifier on and off.
Level: A 31-position detented rotary attenuator for each channel located on the front panel used to control the output level.
Stereo/Mono: A three-position back panel switch used to select Stereo, Bridge-Mono or Parallel-Mono operation.
Sensitivity: A three-position switch located inside the PIP compartment used to select one of three input sensitivities for both channels: 0.775 volts or 1.4 volts for standard 1 kHz power or a voltage gain of 26 dB.
Input Ground Lift: A two position back panel switch used to isolate the phone jack signal grounds from the chassis (AC) ground.
Reset: A back panel button for each channel used to reset the corresponding power supply. 100 and 120 VAC units have 15 amp circuit breakers. 230 VAC units have 7.5 amp circuit breakers.
Enable: This amber indicator is on when the amplifier is switched on to show that the low voltage power supply is operating.
Signal / IOC: Two green indicators flash with medium intensity in sync with the amplifiers outputs to show signal presence. In the unlikely event the output waveform differs from that of the input by 0.05% or more, they flash brightly to indicate distortion. As sensitive distortion indicators they provide proof of performance. Note: It is normal for the Channel 2 IOC indicator to remain on in Parallel-Mono mode.
ODEP: Each channel has a multifunction LED (light emitting diode) indicator that shows the channels energy reserve status. Normally, the LEDs are brightly lit to show that reserve energy is available. In the rare event that a channel has little reserve, its indicator dims in proportion to ODEP limiting. An ODEP indicator may also turn off under other, more unusual circumstances.
Input Connector: Balanced -inch phone jacks on chassis and internal PIP connector. (Balanced 3-pin XLR connectors are provided on the P.I.P.-FX which is a standard feature.)
Input Impedance: Nominally 20 k ohms, balanced. Nominally 10 K ohms, unbalanced.

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 blow-ups. They also protect loudspeakers from input/output DC and turn-on/turn-off transients.If unreasonable operating conditions occur, the patented ODEP circuitry proportionally limits the drive level to protect the output devices, particularly in the case of elevated temperature. Transformer overheating results in a temporary shutdown of the offending channel. When it has cooled to a safe temperature, the transformer automatically resets itself. Controlled slew rate voltage amplifiers protect against RF burnouts, and input overload protection is provided by current-limiting resistance at the input.Turn On: The four second turn-on delay prevents dangerous turn-on transients. Turn-on occurs at zero crossing of the AC waveform, so power sequencers are rarely needed with multiple units. Note: The turn-on delay time may be changed. Contact Crowns Technical Support Group for details.Circuit Breaker: Circuit breaker current ratings vary based on the AC operating power.
