O ur patented variable impedance (VZ
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.
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.
®
) technology permits the Macro-Tech
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.
