MACRO-TECH SERIES

he Crown Macro-Tech Series is the deﬁ n-

ing standard for ampliﬁ er design today.

No compromises, no gimmicks. Just bril-

liant engineering backed by superior manufac-

turing, support and an unsurpassed commit-

ment to quality. Like all Crown amps, the deﬁ n-

ing characteristic of the Macro-Tech Series is

sonic accuracy. A tight, rock-solid low end,

with smooth, detailed highs and a well-deﬁ ned

midrange. In short, the most accurate repro-

duction 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 ampliﬁ er

in the business.

When it comes to manufacturing amps, our

work is based on one simple fact: there are no

shortcuts to quality. And our Macro-Techs have

proven it time and time again in some of the

most demanding applications in the world.

The VZ Series is a signiﬁ cant leap forward

in ampliﬁ er design. Our patented variable

impedance (VZ) technology permits the MA-

3600VZ to dynamically adapt to signal and load

requirements in real time. Whether you need

current in a low-impedance sub-woofer situa-

tion, or high-voltage swings for those transient

signals, the VZs deliver!

Speciﬁ cations

Note: Speciﬁ cations relate to120-volt, 60-Hz units in Stereo

mode with 8-ohm loads and an input sensitivity of 26-dB gain

at 1 kHz rated power unless otherwise speciﬁ ed. Speciﬁ ca-

tions for units supplied outside the U.S.A. may vary slightly at

different AC voltages and frequencies.

Power

Output Power:

Load Impedance: Safe with all types of loads,

even reactive ones. Rated for 2 to 16 ohms in

Stereo, 4 to 16 ohms in Bridge-Mono and 1 to

4 ohms in Parallel-Mono mode.

Voltage Gain to 8-ohm load at rated output at

1 kHz, maximum level setting:

124.6:1 ±6% or 41.9 dB ±0.5 dB at 0.775-volt

sensitivity.

69.2:1 ± 6% or 36.8 dB ±0.5 dB at 1.4-volt

sensitivity.

20:1 ±6% or 26 dB ±0.5 dB at +26 dB sensitiv-

ity.

Required AC Mains: 50/60 Hz; 100-, 120-, and

230 - VAC (±10%) 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; 230 VAC units can draw up to 15 amps.

Current, voltage and frequency requirements

are provided on the unit’s back panel.

AC Line Connector: NEMA TT30P.

Performance

Frequency Response: ±0.1 dB from 20 Hz to

20 kHz at 1 watt.

Phase Response: ±10 degrees from 10 Hz to

20 kHz at 1 watt.

Signal-to-Noise Ratio, 20 Hz to 20 kHz:

Better than 105 dB A-weighted or 100 dB

unweighted below rated power.

Total Harmonic Distortion (THD): At full band-

width power, less than 0.05% from 20 Hz to

1 kHz increasing linearly to less than 0.1% at

20 kHz.

Intermodulation Distortion (IMD): (60 Hz and

7 kHz at 4:1) Less than 0.05% from 368 mil-

liwatts to full bandwidth power.

Damping Factor: Greater than 1,000 from 10

Hz to 400 Hz.

Slew Rate: (Slew rates are limited to useful

levels for ultrasonic/RF protection.) Greater

than 30 volts per microsecond.

Controls

Enable: A front-panel push button used to turn

the ampliﬁ er on and off.

Level: A front-panel 31-detent rotary control

for each channel used to control the output

level.

Stereo/Mono: A three-position back-panel

switch used to select Stereo, Bridge-Mono or

Parallel-Mono mode.

Sensitivity: A three-position switch inside the

PIP™ compartment used to select the input

sensitivity for both channels: 0.775 volts or 1.4

volts for standard 1 kHz power, or a 26 dB

voltage gain.

Reset: A back-panel push button for each chan-

nel used to reset the circuit breaker that pro-

tects each power supply. 100 and 120 VAC

units have 15 amp circuit breakers; 230 VAC

units have 7.5 amp circuit breakers.

Indicators

Enable: An amber front-panel indicator that

shows the on/off status of the low-voltage

power supply.

Signal/IOC: A green front-panel indicator for

each channel that ﬂ ashes to show ampliﬁ er

output. If a channel’s output waveform differs

from its input by 0.05% or more, the indicator

ﬂ ashes brightly

to show distortion. This func-

tion provides proof of distortion-free perfor-

mance. In Parallel-Mono mode, the Channel 2

light stays on.

Features

• Crown’s Grounded Bridge™ design delivers

large voltage swings without using easily

stressed output-transistor configurations

like conventional ampliﬁ ers. The results are

lower distortion and superior reliability.

• Patented ODEP

(Output Device Emulation

Protection) circuitry compensates for over-

heating and overload to keep the ampliﬁ er

working when others would fail.

• IOC

(Input/Output Comparator) circuitry

immediately alerts of any distortion exceed-

ing 0.05%, providing dynamic proof of

distortion-free performance.

• PIP™ (Programmable Input Processor) con-

nector accepts accessory modules that tailor

the ampliﬁ er to suit speciﬁ c applications.

• Articulated VZ

power supplies for each chan-

nel provide excellent crosstalk characteristics

and the best power matching to your load.

• Very low harmonic and intermodulation

distortion result in the best dynamic transfer

function in the industry.

• Balanced 1/4-inch(6.35-mm) phone jack

inputs for each channel, with balanced XLR

connectors on the standard PIP-FX module.

• Full protection from shorted, open and mis-

matched loads; general overheating; DC;

high-frequency overloads; and internal fault

conditions.

• Three Year, No-Fault, Fully-Transferable

Warranty completely protects your investment

and guarantees its speciﬁ cations.
