ur patented variable impedance (VZ
®
) technology permits the Macro-
Tech 3600VZ and the Macro-Tech 5002VZ to dynamically adapt to both
signal and load requirements, providing the best power match to the widest
range of loads. These models pack large amounts of power into a compact
package while achieving ultra-low distortion and without generating exces-
sive heat. Detented controls, PIP expandability and comprehensive status
indicators are included. The Macro-Tech 5002VZ’s universal power supply
adapts to available voltages around the world.

to 30 amps; 230 VAC units can draw up to 15 amps.

Front Panel Controls
Level: Rotary detented level control, one for each
channel.
Compressor (MA-5002VZ only): Controls the
channel’s error-driven compression. Selections
include Off; Fast (4-millisecond attack, 300-mil-
lisecond release), and Slow (12-millisecond attack,
600-millisecond release).
Enable: Push button used to turn the amplifier on
and off.
Back Panel Controls
Input Ground Lift: A two-position switch used to
isolate the input audio signal grounds from the AC
(chassis) ground to help prevent ground loops.
MA-3600VZ switch affects phone inputs only.
Loudspeaker Offset Integration (MA-5002VZ
only): Two-position switch for each channel turns
on or off the loudspeaker protection, which pro-
tects against DC, off-center woofer cone move-
ment, and unwanted subsonic and ultrasonic fre-
quencies.
Sensitivity: Switch for each channel selects input
sensitivity: 0.775 volts or 1.4 volts for standard 1-
kHz power, or a 26 dB voltage gain.
Stereo/Mono: Switch selects Stereo, Bridge-Mono
or Parallel-Mono mode.
VZ Mode (MA-5002VZ only): Switch for each
channel controls the switching mode of the VZ
power supplies.
Front Panel Indicators
Enable: Amber LED indicates amplifier is on and
AC power is available.
Signal/IOC: Green LED for each channel flashes to
show amplifier output. If a channel’s output wave-
form differs from its input by 0.05% or more, the
indicator flashes brightly to show distortion.
ODEP: Amber LED for each channel shows ther-
mal-dynamic energy reserve. A lit indicator shows
available reserve energy. If a channel has no
reserve, its indicator will dim in proportion to ODEP
limiting.
ILoad/ILimit (MA-5002VZ only): Two-color
(green/red) LED for each channel. Green indicates
load current flowing out the amplifier; red indicates
maximum current is being delivered to the load.
Input Connectors
3-pin female XLR and female TRS for each channel.
Output Connectors
MA-3600VZ: Two sets of 5-way, color-coded bind-
ing posts for banana plugs, spade lugs or bare wire
(European models do not accept banana plugs).
MA-5002VZ: High-current output block accepts
banana plugs, spade lugs or bare wire. A detach-
able output cover protects against accidental short
circuits and dangerous electrical shock.
Protection
Macro-Tech amplifiers are protected against short-
ed, open or mismatched loads; overloaded power
supplies; excessive temperature, chain destruction
phenomena, input overload damage and high-fre-
quency blowups. They also protect loudspeakers
from input/output DC and turn-on/turn-off tran-
sients.
Cooling
Internal heat sinks, forced-air cooling for rapid heat
dissipation.
