Our 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.
System Solutions: Both accept most PIP modules. The
MA-5002VZ accepts all current IQ-PIP modules. The
MA-3600VZ can accept IQ-PIP LITE module when
paired with the IQ-PIP USP2 Adapter Kit (some func-
tionality will be limited).

The following applies to units in Stereo mode with 8-ohm loads and rated input sensitivity
unless otherwise specified.

Power
Load Impedance:
MA-3600VZ: Safe with all types of loads. Rated for 2 to 8 ohms in Stereo,
4 to 8 ohms in Bridge-Mono, and 1 to 2 ohms in Parallel-Mono.
MA-5002VZ: Safe with all types of loads. Rated for 2 to 8 ohms in Stereo,
4 to 16 ohms in Bridge-Mono, and 1 to 4 ohms in Parallel-Mono.
Required AC Mains (±10%, –15%): 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. 100 and 120 VAC units can draw up to 30 amps;
230 VAC units can draw up to 15 amps.
Power Draw at Idle: 90 watts or less.
Controls
Compressor (MA-5002VZ only): Controls the channel’s error-driven com-
pression. Selections include Off; Fast (4-millisecond attack, 300-mil-
lisecond release), and Slow (12-millisecond attack, 600-millisecond
release).
Enable: A front-panel push button used to turn the amplifier on and off.
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.
Level: A front-panel rotary detented level control, one for each channel.
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 movement, and unwanted sub-
sonic and ultrasonic frequencies.
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 switch-
ing mode of the VZ power supplies.
Indicators
Enable: Green 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 waveform 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.
Input/Output
Input Connectors: 3-pin female XLR and female TRS for each channel.
Input Impedance: (nominally balanced, nominally unbalanced): 20 k
ohms, 10 k ohms.
Output Connectors,
MA-3600VZ: Two sets of 5-way, color-coded binding 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 detachable output cover protects against acciden-
tal short circuits and dangerous electrical shock.
DC Output Offset (shorted input): ±10 millivolts.
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.
Construction
Cooling: Internal heat sinks, forced-air cooling for rapid heat dissipation.
Dimensions: EIA Standard 19-inch (48.3-cm) rack mount width (EIA RS-310-B),
MA-3600VZ: 3.5-inch (8.9-cm) height and 16-inch (40.6-cm) depth
behind the mounting surface.
MA-5002VZ: 5.25-inch (13.3-cm) height and 15.875-inch (40.3-cm)
depth behind the mounting surface.
