4 Operation
3 Setup
3.7 Connect to AC Mains
4.1 Precautions
4. Never connect the output to a power
supply, battery or power main. Electri-
cal shock may result.
Connect the AC power cordset of your amplifier
to the AC mains power source (power outlet).
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:
5. Tampering with the circuitry, or making unau-
thorized circuit changes, may be hazardous
and invalidates all agency listings.
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.
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
6. Do not operate the amplifier with the Signal/
IOC LEDs constantly indicating an IOC condi-
tion.
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.
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.
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.
3.8 Startup Procedure
Use the following procedure when first turning
on your amplifier:
Remember: Crown is not liable for damage that
results from overdriving other system components.
1. Turn down the level of your audio source.
2. Turn down the level controls of the ampli-
fier.
3. Turn on the “Enable” switch. The Enable
indicator should glow.
4. Turn up the level of your audio source to an
optimum level.
5. Turn up the Level controls on the amplifier
until the desired loudness or power level is
achieved.
6. Turn down the level of your audio source to
its normal range.
If you ever need to make any wiring or
installation changes, don’t forget to turn
off the amplifier and disconnect the
power cord.

ground are referred to as “low-side NPN and
PNP.” Positive current is delivered to the load
by increasing conductance simultaneously in
the high-side NPN and low-side PNP stage,
while decreasing conductance of the high-side
PNP and low-side NPN in synchrony.
(The PIP-Lite can be used with the Macro-Tech
3600VZ.) With ODEP you get the maximum

Guide, available on the Crown website
5.1.2 IOC (Input Output Compara-
tor)
5.1 Protection Systems
Crown's Grounded Bridge design delivers large
voltage swings without stressing output tran-
sistors. The results are higher efficiency, lower
distortion and superior reliablility.
The IOC circuit compares the output signal of
the amplifier with the input signal. If there is
any difference other than gain, then it is consid-
ered distortion and the indicator comes on. The
LED indicator will come on whenever there is
distortion of 0.05% or more. An IOC condition
may also be sensed by an IQ PIP module
installed in PIP-compatible amplifiers.
Your Crown amplifier provides extensive pro-
tection and diagnostic capabilities, including
ODEP and IOC.
5.1.1 Output Device Emulation
Protection (ODEP)
5.2.2 Variable Impedance (VZ)
VZ is the name of Crown's patented articulated
power supply technology. This innovative tech-
nology permits us to pack large amounts of
power into a compact package while achieving
ultra-low distortion and without generating
excessive heat.
Crown invented ODEP to solve two long stand-
ing problems in amplifier design: To prevent
amplifier shutdown during demanding opera-
tion and to increase the efficiency of output cir-
cuitry.
IOC is designed to report any form of distor-
tion. IOC not only checks the waveform for dis-
tortion, but also reports input overload and
even a protective action that mutes or shuts
down an amplifier. With all of these features,
IOC monitors the entire amplifier. When the IOC
indicator is off the amplifier is definitely opera-
tional and undistorted. IOC provides an on-line
proof of performance.
To do this, Crown established a rigorous pro-
gram to measure the safe operating area (SOA)
of each output transistor before installing it in
an amplifier. Crown also designed intelligent
circuitry to simulate the instantaneous operat-
ing conditions of those output transistors. Its
name describes what it does: Output Device
Emulation Protection or ODEP. It not only simu-
lates the operation of the output transistors but
it also compares their operation to their known
SOA. If ODEP sees that more power is about to
be asked of the output devices than they are
capable of delivering under the present condi-
tions, ODEP immediately limits the drive level
until it falls within the SOA. Limiting is propor-
tional and kept to an absolute minimum—only
what is required to prevent the possibility of
output transistor damage.
An amplifier power supply must be large
enough to handle both the maximum voltage
and maximum current necesary for the ampli-
fier to drive its rated power into a specified
load. In order to meet this requirement, most
conventional supplies are heavy, large, and
produce lots of heat. In contrast, the VZ supply
gets more current AND voltage out of a smaller,
lighter, and more efficient package by dynami-
cally adapting to both signal and load require-
ments in real-time. This provides the best
power match to the widest range of loads.
5.2 Circuit Designs
5.2.1 Grounded Bridge
Grounded Bridge is the name of Crown's
unique four-quadrant amplifier topology. The
Grounded Bridge topology takes full advantage
of the power supplies delivering peak-to-peak
voltages to the load that are twice the voltage
seen by the output devices and twice the volt-
age generated by the power supplies.
The VZ supply is divided into two segments.
When the output stage requires high-voltage,
the segments are arranged in series to deliver
twice the voltage of a single segment. When the
output stage requires high-current, the seg-
ments are arranged in parallel to deliver twice
the current of a single segment. Sensing cir-
cuitry "watches" the voltage of the signal to
determine when to switch VZ modes. The
switching circuitry is designed to prevent audi-
ble switching distortion to yield the highest
possible dynamic transfer function—you hear
only the music and not the amplifier.
The power supply bridge rectifier is not ground
referenced, and the transformer secondary is
not center-tapped. This allows the power sup-
ply to deliver +VCC and -VCC from the same
bridge rectifier and filter as a total difference in
potential regardless of their voltages with
respect to ground.
This level of protection enables Crown to
increase output transistor utilization while
greatly increasing amplifier reliability.
Finally, this onboard intelligence is monitored
in two ways. First, the front panel ODEP indica-
tors show whether the amplifier is functioning
correctly or if ODEP is limiting the drive level.
Second, ODEP data is fed to the PIP connector
at the back of the amplifier so advanced PIP
modules like the PIP-Lite can use it to make
decisions and control the amplifier.
Composite output devices are arranged to func-
tion as gigantic NPN and PNP devices. Each
output stage has two composite NPN and two
composite PNP devices. The devices con-
nected to the load are referred to as “high-side
NPN and PNP” and the devices connected to
With VZ, you get not only maximum power and
safety, but you also get the best power match-
ing to your load.

5 Advanced Features and Options
5.3 Options
5.3.2 Input Sensitivity Switch
5.3.3 Input Ground Lift Switch
The Input Sensitivity Switch is located inside the back of
the amplifier (Figure 5.1). It is set at the factory to 0.775
volt for rated output into 8 ohms. It can also be switched
to a sensitivity of 1.4 volts, or a fixed voltage gain of 26
dB (4.8 volts for rated output).
The Input Ground Lift switch is located on the rear panel
(Figure 5.1) and can provide isolation between the input
signal ground and the AC ground. It affects only the
phone jack inputs and has no effect on the input connec-
tors on the PIP module. Sliding the switch to the left iso-
lates or “lifts” the grounds by placing an impedance
between the sleeve of each phone jack and the circuit
ground.
5.3.1 IQ-PIP-USP2 Adapter and PIP-Lite
Module
Available in limited quantity through Crown’s Parts
Department, the IQ-PIP-USP2 Adapter allows the ampli-
fier to accept the Crown PIP-Lite module (but not the
PIP-USP3 or PIP-USP3/CN.) Load monitoring and out-
put voltage limiting are not available with the IQ-PIP-
USP2 Adapter.
How to change the input sensitivity:
1. Turn off the amplifier and disconnect its power cord
from the AC mains power receptacle.
When a PIP module is plugged into the amplifier, only the
noninverted and inverted signal lines are connected in
parallel with the corresponding lines of the input phone
jacks. The signal grounds are not paralleled. For exam-
ple, XLR pins 2 and 3 are connected in parallel with the
tip and ring of the corresponding phone jack. However
pin 1 of the XLR is not connected in parallel with the
sleeve of the phone jack.
The PIP-Lite connects the amplifier to a 100 Mb Ether-
net network allowing it to be remotely controlled and
monitored via IQwic or System Architect.
2. Remove the PIP module (two screws).
3. Locate the sensitivity switch access hole inside the
chassis opening as shown in Figure 5.1. It is located
just above the phone jack inputs.
The PIP-Lite is a TCP/IQ series component. This means
it connects to Harman Pro System Architect software or
an IQ System® via 100 Mb Ethernet. This provides faster
IQ communications than the previous current loop, IQ
bus, connectivity method. With this control network
option, a large (or small) system can be interconnected
using standard off-the-shelf 100 Mb Ethernet compo-
nents (Switches, NICs, and cables). The PIP-Lite can
also be connected to the same network used to pass
CobraNet™ audio1.
4. Set the switch to the desired position noted on the
access hole label. The position toward the front panel
sets the sensitivity to 1.4 volts for rated output, the
middle position provides a voltage gain of 26 dB, and
the position toward the back panel sets the sensitivity
to 0.775 volt for rated output.
5. Replace the PIP module and restore the power.
The audio path in the PIP-Lite is processed totally in the
analog domain. While DSP-type functions cannot be
supported with this type of architecture, the standard
SmartAmp features are. These features include input
compressors, multimode output limiters, and error
reporting.

POSSIBLE REASON:
CONDITION: Normal operation.
POSSIBLE REASON:
•
•
The amplifier's Power switch is off.
The amplifier is not plugged into the power
receptacle.
• This is normal operation for your amp.
•
The amplifier's low-voltage power supply
fuse has blown. Return amp to Crown or an
authorized Crown Service Center for
servicing.
• The amp is set for Parallel Mono mode.

level which causes the Signal/IOC LEDs
to constantly indicate an IOC condition.
•
•
ODEP limiting has been activated. Take
appropriate measures to keep the ampifier
out of ODEP limiting (see Section 5.1.1
for more information about ODEP).
ODEP limiting has been activated. Take
appropriate measures to keep the ampli-
fier out of ODEP limiting (see Section
5.1.1 for more information about ODEP).
The amplifier is in drive protection mode.
