Front Panel Controls and Indicators

Bridge Mode Indicator: Yellow LED illuminates

when the rear-panel Mode Switch is set to the
“Bridge” position.

Ready Indicator: Green LED, one per channel,
illuminates when the channel is initialized and
ready to produce audio output. Indicator is off
when PIP puts the amplifi er in standby mode via
the control system.

Signal Indicators: Three green LEDs per chan­nel indicate the amplifi er’s input and output
signal levels.

Signal: input signal is above –40 dBu.
–20 dB: amplifi er output is 20 dB below clipping.
–10 dB: amplifi er output is 10 dB below clipping.

Clip Indicator: Red LED, one per channel,
illuminates when the channel’s output signal
reaches the onset of audible clipping. The Clip
Indicator also will illuminate during Thermal
Level Control (TLC) limiting or when the input
compressor/limiter is protecting the amplifi er
from input overload.

Thermal Indicator: Red LED, one per channel,
illuminates when the channel has shut down,
or is very near shutting down, due to thermal
stress or overload.

Fault Indicator: Red LED, one per channel,
fl ashes when the amplifi er output channel has
stopped operating.

Data Indicator: Yellow LED indicates control
data activity (if the amplifi er is equipped with
an IQ-PIP2 module, and connected to a control
system).

Power Indicator: Blue LED indicates amplifi er
has been turned on and AC power is available.
The LED will fl ash when the AC line voltage is
15% above or 25% below the nominal rated
value.

Cooling Vents: Front-to-rear forced airfl ow.
Power Switch: Push-on / push-off switch.

Back Panel Controls and Connectors

Power Cord Connector: Standard 15 amp IEC

inlet. Voltage is indicated above IEC inlet.
Reset Switch: Resets the circuit breaker that

protects the power supply.
Speaker Connectors: One four-pole touch-proof

terminal strip. Accepts up to 10 AWG terminal
forks.

Input Connectors: Balanced 2-pin terminal block
connector, one per channel, on the standard
PIP2-BBY module.

Channel Level Control: One 21-position
detented rotary attenuator per channel, ranging
from minus infi nity (–70 dB) to 0 dB gain.

Mode Switch: Two-position switch is used to
select the amplifi er’s mode of operation: Dual or
Bridge-Mono.

Highpass Filter: One 3-position switch per
channel selects between OFF, 35Hz and 70Hz
3rd-order fi lters.

“Y” Input Switch: When set to ON, this switch
parallels the input signals of the two channels
for use when the input signal is mono. Also can
be used to daisy-chain the signal to another
amplifi er.

Ventilation Grille: Front-to-rear forced airfl ow.

Options

PIP2 modules, including the PIP-Lite, PIP-USP3,
and PIP-USP3/CN.

Protection Systems

Thermal Level Control (TLC): If an amplifi er

channel starts to overheat, the TLC circuit will
engage the input compressor. By compressing
the input, the amplifi er will not generate as much
heat and will have a chance to cool down.

Junction Temperature Simulation (JTS): In the
CTs 600/1200, if excess power is demanded,
JTS circuitry limits the drive level of the output
devices to a safe range, preventing damage.

Fault: The amplifi er will light the Fault LED if the
amplifi er output stage stops operating.

AC Under-/Over-Voltage Protection: If the AC
line voltage drops below 25% or rises above
15% of the nominal operating voltage of the
amplifi er, the amplifi er’s power supply turns
off and the blue Power LED fl ashes. The ampli­fi er will turn back on when the AC line voltage
returns to safe operating levels.

Circuit Breaker: This breaker protects the ampli­fi er from excessive AC current draw.

DC Output Servo: The output servo circuit
protects your drivers by eliminating DC offset,
even in the presence of very large asymmetrical
signals.

In-rush Limiting: A soft-start circuit in the
power supply minimizes the amplifi er’s current
draw during power-on.

Variable-speed Fan: Two continuously variable
speed fans direct the airfl ow through the ampli­fi er for cooling.

Ready Indicator: Green LED, one per channel,
illuminates when the channel is initialized and
ready to produce audio output.

rown’s CTs Multi-Channel Series offers wide flexibility for a wide range of installed sound applica-

C

tions. CTs Multi-Channel Series amplifiers offer independent selection of high- and low-impedance

operation for each channel pair, making these amps ideal for multi-zone installations.

Signal Indicator: Green LED, one per channel,
illuminates to indicate the presence of input
signals above –40 dBu.

Clip Indicator: Red LED, one per channel, illu­minates when the THD of the channel’s output
signal rises to a level typically considered as
the onset of audible clipping. The Clip Indicator
also will illuminate during Thermal Level Control
(TLC) or input overload.

Thermal Indicator: Red LED, one per channel,
fl ashes when a state of thermal stress or over­load has caused the channel to shut down. If
the power supply goes into thermal overload, all
channel LEDs will fl ash.

Fault Indicator: Red LED, one per channel,
fl ashes when a fault condition has occurred in
the channel.

Ventilation Grille: Front-to-rear forced airfl ow.
Data Indicator: Yellow LED indicates IQ Loop

data activity (if the amplifi er is equipped with an
IQ-MC module, and connected to an IQ Loop).

T-170V: This is an autoformer that allows 100V
output from the amplifi er, and allows other
amplifi ers without direct constant voltage output
to be easily integrated into distributed systems.

TP-170V: This is a rack-mountable panel with
four autoformers as described above.

Protection Systems

Thermal Level Control (TLC): If an amplifi er
channel starts to overheat, the TLC circuit will
engage that channel’s input compressor. By
compressing the input, the amplifi er will not
generate as much heat and will have a chance
to cool down. The degree of compression is
proportional to the amount of overheating. If
the channel becomes too hot for safe operation
even after full TLC limiting, the channel will shut
off, and the Thermal Indicator for that channel
will fl ash brightly to alert the user that a state of
thermal stress or overload has cause the chan­nel to shut down.

FIT (Fault Isolation Topology): Isolates faults within
affected channels.

Fault: If an amplifi er channel requires service,
the corresponding Fault indicator will illuminate
to alert the user of this condition. If this occurs,
return the amplifi er to the Crown factory or to an
authorized Crown service center.

High-Pass Filter: A fi xed 35-Hz (70-Hz in CTs

4200) high-pass fi lter per channel pair is auto­matically inserted when the mode switch is set
to either of the constant-voltage settings. The
high-pass fi lter corner frequency in the CTs 8200
can be set to 70 Hz, or bypassed, with a service
option.

AC Under-/Over-Voltage Protection: If the AC
line voltage varies out of an acceptable range,
the amplifi er’s power supply turns off and the
blue Power LED fl ashes. The amplifi er will turn
back on when the AC line voltage returns to safe
operating levels.

Controls

Compressor (MA-5002VZ only): A three-position
back-panel switch is used to control each channel’s
input compressor. The “fast” setting provides an attack
time of 4 milliseconds and a release time of 300 mil­liseconds; the “slow” setting provides an attack time of
12 milliseconds and a release time of 600 milliseconds;
the “off” setting defeats output-driven compression.

Enable: A front-panel push button used to turn the
amplifi er on and off.

Input Ground Lift (MA-5002VZ only): A two-position
back-panel switch located on the PIP2-FXQ used to
isolate the input audio signal grounds from the AC
(chassis) ground.

Level: A front-panel rotary potentiometer for each
channel with 31 detents is used to control the output
level.

Loudspeaker Offset Integration (MA-5002VZ only): A
two-position back-panel switch for each channel used
to turn the loudspeaker protection circuitry on and off.

The circuitry protects against DC, off-center woofer
cone movement, and unwanted subsonic and ultrasonic
frequencies.

Stereo/Mono: A three-position back-panel switch used
to select Stereo, Bridge-Mono or Parallel-Mono mode.

Sensitivity: A three-position switch used to select the
input sensitivity for both channels: 0.775 volts or 1.4
volts for standard 1 kHz power, or a 26 dB voltage gain.
MA-3600VZ switch is inside the PIP compartment; MA­5002VZ switch is on the back panel.

VZ Mode (MA-5002VZ only): A four-position switch for
each channel inside the front-panel used to control the
switching mode of the VZ power supplies.

Reset (MA-5002VZ only): A back-panel push button
for each channel used to reset the circuit breaker that
protects each power supply. 100 and 120 VAC units
have 15 amp circuit breakers; 230 VAC units have 7.5
amp circuit breakers.

Indicators

Enable: An amber front-panel indicator that shows the
on/off status of the low-voltage power supply.

Signal/IOC: A green front-panel indicator for each
channel that fl ashes to show amplifi er output. If a
channel’s output waveform differs from its input by

0.05% or more, the indicator fl ashes brightly to show
distortion. This function provides proof of distortion­free performance. In Parallel-Mono mode, the Channel
2 light stays on.

ODEP: Each channel has an amber front panel indicator
that shows thermal-dynamic energy reserve. Normally,
each ODEP indicator is lit to show available reserve
energy. The indicator will dim proportionally as the
energy reserve for its channel descreases. In the rare
event that a channel has no reserve, its indicator will
turn off and the ODEP circuitry will limit the channel’s
output drive.

ILoad/ILimit (MA-5002VZ only): A two-color (green/
red) LED for each channel that shows load current and
limit current. They glow green to indicate load cur­rent fl owing out the amplifi er, and they turn red when
maximum current is being delivered to the load.

Input/Output

Input Connector: Two balanced 1/4 inch TRS

(6.35-mm) phone jacks on the back panel and two
balanced three-pin female XLR connectors on the
factory-installed PIP-FX (MA-3600VZ) or PIP-FXQ (MA­5002VZ) module.

Input Impedance (Nominal):

MA-3600VZ: 20 k ohms, balanced. 10 k ohms,

unbalanced.
MA-5002VZ: Greater than 10 k ohms, balanced.
Greater than 5 k ohms, unbalanced.

Maximum Input Level: 13 volts peak.
Input Sensitivity: 0.775 volt for standard 1 kHz power,

1.4 volts for standard 1 kHz power, or a 26 dB voltage
gain.

Output Connectors (MA-3600VZ): Two sets of color­coded binding posts.

Output Connectors (MA-5002VZ): A multifunction,
high-current output block is provided. Crown output
blocks include three pairs of connectors for each
channel (a total of 12 connectors). This allows multiple
loudspeakers to be easily connected to each channel.
High current screw terminals and color coded binding
posts.

Output Impedance: Less than 10 milliohms in series
with less than 2 microhenries (MA-3600VZ) or 2.5
microhenries (MA-5002VZ).

DC Output Offset: (Shorted input) ±10 millivolts.
Output Signal
Stereo: Unbalanced, two-channel.

Bridge-Mono: Balanced, single-channel. Channel 1

controls are active; Channel 2 should not be used.
Parallel-Mono: Unbalanced, single-channel. Channel 1

controls are active; Channel 2 controls are bypassed.

Protection

Macro-Tech amplifi ers 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.

If unreasonable operating conditions occur, the pat­ented ODEP circuitry will proportionally limit the drive
level to protect the output transistor stages, particularly
in the case of elevated temperature. Transformer
overheating will result in a temporary shutdown of the
affected channel; when it has cooled to a safe tem­perature, the transformer will automatically reset itself.
Controlled slew-rate voltage amplifi ers prevent RF
burnouts, and input overload protection is provided by
current-limiting resistance at the input.

Turn On: Four-second delay with no dangerous tran­sients. Delay time can be changed in the
MA-3600VZ (contact Crown’s Technical Support
Group). MA-5002VZ also has “soft start” to avoide
tripping the AC circuit breaker by gradually bringing the
supplies up to full voltage.

Construction

Durable black fi nish on aluminum front panel
with gray suede Lexan insert. Aluminum
chassis provides maximum heat conduction
and minimum weight.

Dimensions: 19-inch (48.3 cm) rack mount
width, 1.75 inches (4.5 cm) high, 8.5 inches
(21.6 cm) deep behind the mounting surface,
and a 0.625-inch (1.6-cm) protrusion in front
of the mounting surface.

Net Weight:

D-45: 8 lb, 11 oz (3.9 kg)
D-75A: 9 lb, 7 oz (4.3 kg).

Shipping Weight:

D-45: 10 lb, 9 oz (4.8 kg)
D-75A: 11 lb, 4 oz (5.1 kg).

Cooling: The amplifi er is totally convection

cooled. The entire aluminum chassis acts as
a conductor to dissipate heat. The covers and
front panel extrusion also act as heat sinks.
Much of the unit’s heat is conducted through
the extruded front panel. This design is used
so that front panel contact with the equipment
rack will also dissipate heat.

Wall-Mount Controllers

Crown VCAP panels are wall-mounted panels
with potentiometers that provide remote control
of the volume of Crown CTs amplifier channels
via a VCA-MC4 or VCA-MC8 module installed in
the amplifier. Two models are available: 1-VCAP
and 4-VCAP.

1-VCAP: Used in conjunction with a VCA-MC
module, this is a 1-gang panel with one poten­tiometer that provides remote volume control
for one or more CTs amplifier channels. The
potentiometer on the panel is wired directly
to the VCA connectors on the VCA-MC.

4-VCAP: This is a 2-gang panel with four poten­tiometers that provide remote volume control
for four or more CTs amplifier channels. The
potentiometers on the panel are wired directly
to the VCA connectors on the VCA-MC.

Remote Level Control

The Crown VCA-MC4A and VCA-MC8 are optional
level-control modules for the Crown CTs multi-chan­nel power amplifiers. The VCA-MC4A is for the CTs
4200, and the VCA-MC8 is for the CTs 8200.

A VCA-MC module provides independent remote
level control for each channel. 4-pin removable
Phoenix-style barrier connectors provide the
+10VDC control voltage, ground, and control lines
for two amplifier channels. Thus, the 4-channel
CTs 4200 uses two connectors; the 8-channel CTs
8200 uses four connectors. Crown CTs 4200 and
8200 amplifiers can be supplied with a VCA-MC
module already factory-installed, or your choice of
MC modules can be easily added to the amplifier
by any authorized Crown Service Center.

Choosing the Right Module

To order accessory modules for your amplifier, please
refer to the model tag (located on the back panel of the
amplifier) for your amplifier’s specific model number.
Then refer to the information below to select the correct
accessory for your requirements.

T-170V Constant-Voltage
Transformer

The Crown T-170V is a single
autoformer that provides imped­ance matching between an ampli­fier output and “constant voltage”
loudspeakers. It allows amplifiers
without direct 70V or 100V out-

put capability to drive distributed speaker systems
designed to operate at those voltages.

of each NEW Crown product, for a period of three (3) years from the date of purchase by the original purchaser (the “warranty period”) that the new Crown prod­uct is free of defects in materials and workmanship, and we further warrant the new Crown product regardless of the reason for failure, except as excluded in this
Warranty.

Warranty is only valid within the country in which the product is purchased.

1 Note: If your unit bears the name “Amcron,” please substitute it for the name “Crown” in this warranty.

ITEMS EXCLUDED FROM THIS CROWN WARRANTY

This Crown Warranty is in effect only for failure of a new Crown product which occurred within the Warranty Period. It does not cover any product which has been
damaged because of any intentional misuse, accident, negligence, or loss which is covered under any of your insurance contracts. This Crown Warranty also does
not extend to the new Crown product if the serial number has been defaced, altered, or removed.

WHAT THE WARRANTOR WILL DO

We will remedy any defect, regardless of the reason for failure (except as excluded), by repair, replacement, or refund. We may not elect refund unless you
agree, or unless we are unable to provide replacement, and repair is not practical or cannot be timely made. If a refund is elected, then you must make the
defective or malfunctioning product available to us free and clear of all liens or other encumbrances. The refund will be equal to the actual purchase price,
not including interest, insurance, closing costs, and other finance charges less a reasonable depreciation on the product from the date of original purchase.
Warranty work can only be performed at our authorized service centers. We will remedy the defect and ship the product from the service center within a
reasonable time after receipt of the defective product at our authorized service center.

HOW TO OBTAIN WARRANTY SERVICE

You must notify your local Crown importer of your need for warranty service within the warranty period. All components must be shipped in the original box.
Corrective action will be taken within a reasonable time of the date of receipt of the defective product by our authorized service center. If the repairs made by our
authorized service center are not satisfactory, notify our authorized service center immediately.

DISCLAIMER OF CONSEQUENTIAL AND INCIDENTAL DAMAGES

YOU ARE NOT ENTITLED TO RECOVER FROM US ANY INCIDENTAL DAMAGES RESULTING FROM ANY DEFECT IN THE NEW CROWN PRODUCT. THIS INCLUDES
ANY DAMAGE TO ANOTHER PRODUCT OR PRODUCTS RESULTING FROM SUCH A DEFECT.

WARRANTY ALTERATIONS

No person has the authority to enlarge, amend, or modify this Crown Warranty. This Crown Warranty is not extended by the length of time which you are
deprived of the use of the new Crown product. Repairs and replacement parts provided under the terms of this Crown Warranty shall carry only the unex­pired portion of this Crown Warranty.

DESIGN CHANGES

We reserve the right to change the design of any product from time to time without notice and with no obligation to make corresponding changes in prod­ucts previously manufactured.

LEGAL REMEDIES OF PURCHASER

No action to enforce this Crown Warranty shall be commenced after expiration of the warranty period.
