O 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 excessive 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.

Required AC Mains (MA-3600VZ) :
50/60 Hz; 100, 120, and 230VAC (±10%) units are
available. 230VAC, 50/60 Hz units can be used with
220 and 240VAC. 100VAC and 120VAC units can
draw up to 30 amps; 230VAC units can draw up to
15 amps. Current, voltage and frequency require-
ments are provided on unit’s back panel.
Required AC Mains (MA-5002VZ) :
50 or 60 Hz; 100, 120, 200, 208, 230, 240VAC
(±10%). Current, voltage and frequency require-
ments are provided on unit’s back panel.
Power Draw at Idle: 90 watts or less.
Front Panel Controls and Indicators
Level: Rotary detented level control, one for each
channel.
Enable: Push button used to turn the amplifier on
and off.
Enable LED: 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
thermal-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.
Back Panel Controls and Connectors
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).
Input Ground Lift (MA-5002VZ only): A two-posi-
tion switch used to isolate the input audio signal
grounds from the AC (chassis) ground to help
prevent ground loops.
Loudspeaker Offset Integration (MA-5002VZ
only): Two-position switch for each channel
turns on or off the loudspeaker protection, which
protects against DC, off-center woofer cone move-
ment, and unwanted subsonic and ultrasonic
frequencies.
Sensitivity: Switch for both channels 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.
Input Connectors
3-pin female XLR and female TRS for each channel.
Output Connectors
MA-3600VZ: Two sets of color-coded binding
posts for banana plugs 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 detachable output cover protects against
accidental short circuits and dangerous electri-
cal shock.
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.
Cooling
Internal heat sinks, forced-air cooling for rapid heat
dissipation.
