Macro-Tech MA-3600VZ Power Amplifier
3 Setup

3.7 Connect to AC Mains

Connect the AC power cordset of your amplifier
to the AC mains power source (power outlet).
NOTE: The third prong of this connector
(ground) is an important safety feature. Do not
attempt to disable this ground connection by
using an adapter or other methods.
Amplifiers don't create energy. The AC mains
voltage and current must be sufficient to deliver
the power you expect. You must operate your
amplifier from an AC mains power source with
not more than 10% variation above or below the
amplifier's specified line voltage and within the
specfied frequency requirements (indicated on
the amplifier's back panel label). If you are
unsure of the output voltage of your AC mains,
please consult your electrician.

3.8 Startup Procedure

Use the following procedure when first turning
on your amplifier:
1. Turn down the level of your audio source.
2. Turn down the level controls of the ampli-
3. Turn on the "Enable" switch. The Enable
4. Turn up the level of your audio source to an

6. Turn down the level of your audio source to
If you ever need to make any wiring or
installation changes, don't forget to turn
off the amplifier and disconnect the
power cord.

4 Operation

4.1 Precautions

Your Macro-Tech Series amplifier is protected from
internal and external faults, but you should still
take the following precautions for optimum perfor-
mance and safety:
1. Before use, your amplifier first must be con-
figured for proper operation, including input
and output wiring hookup. Improper wiring
can result in serious operating difficulties. For
information on wiring and configuration,
please consult the Setup section of this man-
ual or, for advanced setup techniques, consult
Crown's Amplifier Application Guide available
online at www.crownaudio.com.
2. Use care when making connections, selecting
signal sources and controlling the output
level. The load you save may be your own!
3. Do not short the ground lead of an output
cable to the input signal ground. This may
form a ground loop and cause oscillations.
4. Never connect the output to a power
supply, battery or power main. Electri-
cal shock may result.
5. Tampering with the circuitry, or making unau-
thorized circuit changes, may be hazardous
and invalidates all agency listings.
6. Do not operate the amplifier with the Signal/
IOC LEDs constantly indicating an IOC condi-
tion.
7. Do not overdrive the mixer, which will cause a
clipped signal to be sent to the amplifier. Such
signals will be reproduced with extreme accu-
racy, and loudspeaker damage may result.
8. Never operate the amplifier with less than the
rated load impedance. Due to the amplifier's
output protection, such a configuration may
result in premature clipping and speaker dam-
age.
Remember: Crown is not liable for damage that
results from overdriving other system components.
