Quick Start!

You’ve waited a long time for this! We know you just can’t wait
to crank up your new Crown®

CE-Series

amplifier. And you
sure don’t want to flip through pages of tech-talk just to find out
where the “ON” switch is. So that’s why we provided you with
this quick and simple page to get you up and running right
away. Just take a few minutes to read through this—no more
than five or ten, max—you’ll be glad you did.

1. Make sure the

CE-Series

amp and all other equipment is
turned OFF before you begin wiring. By the way, the amp
power switch is located on the far left side of the front
panel. It is OFF when depressed on the left.

2. Mount your

CE-Series

amp securely in the rack, or posi-

tion it on a solid surface.

3. Connect the left and right inputs coming from your mixer,
preamp, or processor. You can use either balanced

1

/4-inch
phone, 3-pin XLR or barrier block connectors. You can also
choose to run in MONO mode. (See Figures 2.6 and 2.8.)

4. Connect the output wiring (left and right speakers). You
will need two (2) Neutrik Speakon

®

NL4FC mating con-

nectors.

5. Connect your

CE-Series

amp and other equipment to the

appropriate power source.

6. Turn on your mixer, preamp, signal processor, or any
other equipment in your system EXCEPT your

CE-Series

amplifier. (Remember: the best is worth waiting for.)

7. Make sure the Channel 1 and Channel 2 level (volume)

controls on your

CE-Series

amplifier are turned all the way
down (counter-clockwise), then flip the power switch ON.
Note: The Fault light blinks a few times, and the “Power”
light will glow a bright green to indicate power is on.

8. (Now comes the fun!) Supply input, adjust amp levels
and enjoy.

9. Y ou can check the green signal light to verify input, if nec­essary .

Did You Remember To

CAUTION: Excessive output levels may toast your speak­ers. Crown’s

CE-Series

amplifiers have such low distor­tion, you may not realize the actual level being reached
until it’s too late. Please exercise caution and drive your
speakers responsibly (or at least warn your neighbors!).

Thanks for buying this

CE-Series

amplifier. Here at Crown, we
appreciate your support, and we think you’ll find that you’ve
also done yourself a favor by choosing Crown. That’ s because
the

CE-Series

amps are REAL Crown amplifiers, designed by

dedicated Crown engineers to fit your needs AND your wallet.
Yes, these Crown engineering dudes, cool guys that they are,

thought that no-one should be without that great Crown sound.
So what if you’re not running a pro tour (yet)? You deserve the
best in amplified sound. And the best, of course, is still Crown.
(My dad always said, it ain’t braggin’ if it’s true.)

The engineers at Crown got together and thumbed their noses
at those high-ranking corporate types who always want big
stickers and huge markups. What they came up with is the

CE-Series

of amplifiers. We think you’ll really like it.

So what else is special about the

CE-Series

?

First off, your

CE-Series

amplifier features all front-panel con­trols for ease of use. But—so you don’t have to sacrifice secu­rity for comfort—the front panel level controls can be set, then
removed entirely from the panel. Whether for long-term control
in a fixed installation or short-term protection against unautho­rized adjustments, this feature allows you to just set-and-for­get your level controls.

Welcome

Page 11

CE-Series

Fig. 1.1
The CE-Series
Amplifier

Your

CE-Series

amp also comes with a standard SST module
(System Solution Topologies) that gives you the choice of bar­rier strip,

1

/4-inch phone, or 3-pin XLR connectors and works
great in most situations. However, if you’re using your CE amp
for theater applications, or if you have other special input
needs, you can pull the standard SST module and simply plug
in one of our advanced SST modules, (such as our electronic
crossover).

Don’t forget the impressive output. The CE 1000 pr oduces an
awesome 1,100 watts, while the CE 2000 pumps out 1,975
watts of power .* For output connectors, the

CE-Series

features

genuine Neutrik Speakon

®

4-pole connectors for quick, se-

cure and safe connections.
And, of course, there’ s no mistaking a

CE-Series

amp. Its rugged

look will impress your friends almost as much as the Crown name.
This manual will help you correctly set up and use your new

amplifier—we strongly recommend you read all instructions,
warnings and cautions. Also, for your protection, please send

2 Detailed Install

Follow these instructions for a detailed explanation of

CE-Se-

ries

installation procedures and options. If you just want to get
up and running as quickly as possible, see the Quick Start
section on page 6.

2.1—Begin with the amplifier turned off and disconnected

from the power receptac le. The

CE-Series

power switch
is located on the left side of the front panel; it is OFF when
depressed on the left. Equipment that will be connected
to the inputs of the amplifier (such as mixers,equalizers or
signal processors) should also be turned off.

2.2—Mount the amplifier. Your

CE-Series

amp can be
mounted in a standard, 19-inch (48.3-cm) equipment
rack, or it can be simply stacked with other equipment.
And since your

CE-Series

amp is not as deep as many
amplifiers (only 12.25 inches (31.11 cm) behind the front
panel), you can also mount it in the shallow, wall-mount
racks.

Fig. 2.1
Mounting
Dimensions

If you choose to mount your amp in a rack, you should
secure the back of the rack as well as the front. Securing
the amp at both front and rear will assure that the amp
stays in place, even when the rack is transported or acci­dentally dropped (which we know never happens).

Page 15

CE-Series

Amps with an Attitude!

2.3—Set the mode switch. Turn off the amplifier before mov­ing this switch. The Mode switch should be in the “Stereo”
position when you’re running in Stereo Mode. Stereo
Mode allows independent inputs on the left and right
channels to feed separate speakers at the output. It’s the
configuration typically chosen (by 90% of left-handed
musicians) for everyday audio applications.

Fig. 2.2
Mode Switch

Fig. 2.3
Input
Sensitivity
Switch

Tu rn the Mode switch to “Bridge-Mono” to have a single
input that feeds to a single output with twice the voltage
of Stereo Mode. Use this configuration if you want to give up
stereo capabilities in order to drive your speakers

louder.

(note that the wiring will also need to be changed for this
configuration—see step 6 later in this section).

2.4—Set the Input Sensitivity switch to the desired setting.

T wo choices are available: 1.4 V for full rated (8-ohm) out­put, or a fixed voltage gain of 26 dB. (The

CE-Series

ship
from the factory with default settings of 1.4 V, which trans­lates to approximately 33 dB of gain.) Refer to the infor­mation on “Input Sensitivity” in the Operation section
(section 3) for detailed information.

Page 16

CE-Series

Amps with an Attitude!

2.5—Connect the inputs of the

CE-Series

amp to your mixer ,
equalizers, or signal processors ahead of the amp. Three
types of balanced input connectors are provided, allow­ing you to choose barrier strip, 1/4-inch phone or 3-pin
XLR connectors. You can also choose to use either bal­anced or unbalanced wiring. (See the information on
“Balancing the Line” in the Other Issues section for an
explanation of balanced vs. unbalanced wiring.)

If the Mode switch is in “Bridge-Mono” position, only the
Channel 1 input connectors should be used.

Fig. 2.4
Typical Input
Wiring

Input Wiring Tips

1. For all input connectivity, use shielded wire only. Cables with a foil
wrap shield or a high-density braid are superior. Cables with a
stranded spiral shield, although very flexible, will break down over
time and cause noise problems.

2. Try to avoid using unbalanced lines with professional equipment. If
you have no choice, keep the cables as short as possible. (Refer to

the information on “Balancing the Line” in the Other Issues section.)

3. To minimize hum and crosstalk, avoid running low-level input, high-level output and AC
power feeds in the same path. Try to run differing signal paths at 90° to one another. If you
must use a common path for all cables, use a star-quad cable for the low-level signals.

4. When changing input connectors or wiring, turn the amplifier level controls all the way
down (counter-clockwise) before connecting or disconnecting input plugs.

5. When changing output connections, a professional dude will turn the amplifier level down
and the AC power off to minimize the chance of short-circuiting the output.

Output Wiring Tips

1. Although this amp has Speakon connectors to minimize wiring mis­takes, we encourgage you to choose carefully when selecting
speaker enclosue connectors.

2. To prevent possible short circuits, wrap or otherwise insulate ex­posed loudspeaker cable connectors.

3. Do not use connectors that might accidentally tie conductors together when making
or breaking the connection (for example, a standard, 1/4-inch stereo phone plug).

4. Never use connectors that could be plugged into AC power sockets. Accidental AC
input will be an electrifying experience for your equipment. But you will find out real
quick if your speakers are any good at 60 Hz.

5. Avoid using connectors with low current-carrying capacity, such as XLRs.

6. Do not use connectors that have any tendency to short.

7. To maintain good bass response, use the lowest DC resistance cable you can afford
and will terminate safely in your connectors.

2.6.6—Slide the chuck (D) along the cable and insert into the
housing, making sure that the large notch on the outer
edge of the chuck lines up with the large groove on the
inside of the connector housing. The chuck should slide
easily into the insert/housing combination until only ap­proximately 3/8-inch (9.5-mm) of the chuck end extends
from the back end of the connector as shown in Figure

2.12.

Housing Assembly

2.6.7—Slide the bushing along the cable and screw onto the
end of the connector combination as shown in Figure

2.13. Note that the bushing features a special locking

construction which will prevent disassembly of the
NL4FC connector once this cap is tightened into
place. Before tightening, you may want to test the
connector to make sure it has been assembled prop­erly.

T o test the connector, complete the remaining instal-

lation steps.

Why Speakon?

For amplifiers, the most popular termination device on professional
products has been the dual banana (which incidentally was pioneered
by Crown with the DC300 model). However, recent regulatory require­ments in Europe have outlawed the use of the dual banana plug and
forced users to terminate speaker cables with spade lugs or bare
ends—an approach that is clearly not advantageous to the customer

who wants to reconfigure his system or quickly change out a defective product. It is
possible that similar regulatory controls will appear worldwide over the next few years.

One solution to this problem is to use the Neutrik Speakon® connector. Here at Crown,
we wanted to develop a system for you that eliminated the need for specialized, time­consuming, interface cables. The major loudspeaker manufacturers have been using
Speakon connectors for the input termination on their products for several years now,
so you can be assured of the connector’s reliability in the workplace. With Speakon
connectors, you can plug straight from the amp to the speaker, and start making those
great sounds right away.

The Speakon connector used on this amplifier meets all known safety regulations.
Once wired correctly, the connector cannot be plugged in backwards, causing the
type of inverted polarity situations that are common with banana hookups. It will provide
a safe, secure and reliable method of interfacing your amplifier to the load.

Cooling Tips

If you allow spaces between pieces of equipment in your rack,
make sure you block the front with blank, solid (not perforated) pan­els. This will allow the rack to act as a chimney with hot air exhaust­ing at the top, not re-circulating between adjacent amplfiers.

2.7—Turn on all equipment ahead of the amplifier such as
the mixer or preamplifier. Adjust their signal levels to their
optimum “signal to noise” settings as defined in their op­erating manuals.

2.8—Plug the amplifier into the power receptacle, turn on
the amplifier and adjust its level controls to a desired

setting. Please be sure to follow the steps outlined in the
Operation section (page 29) if this is the first time the am­plifier is being turned on.

2.9—Check to make sure adequate ventilation has been
provided. Even though this amplifier has some of the

most efficient heat sinks in the marketplace, it must be
able to breathe. So make sure that the front vents are
never blocked and that the exhaust fan (out the back) is
not blocked or covered by cables.

An amplifier running at high sound pressure levels into
low-impedance loads, will typically put out lots of hot air,
so make sure it can go somewhere.

If you are running y our equipment in dusty or dirty en­vironments, it is advisable to pre-filter the air using in­dustrial furnace filters. These filters can be taped or
fastened to the front of the equipment rack, ensuring a
clean air supply through a large surface area that will
require minimum maintenance.

3 Operation

Operating a

CE-Series

amp is very straight-forward.

Indicators

See Figure 3.1 for positions of front-panel contr ols and indica­tors.

Fault: OFF is good. This red indicator will blink under five dif­ferent conditions:

1. When the amplifier is first powered up, until the unit is
ready for operation.

2. If the heatsinks reach a temperature above normal work­ing limits.

3. If the transformer thermal protection circuit is activated.

4. If amplifier output wires develope a short-circuit.

5. Should the amplifier output stage become non-opera­tional.

This circuit may be monitored remotely by plugging into the
back-panel RJ11 jack (Fault), and using a circuit like the one
described in Figure 5.2. Under some conditions, the output of
the amplifier will be muted.

Clip: The red Clip indicators turn on when distortion is audible
in the amplifier output.

Signal: Unlike some of our other amplifiers, on the

CE-Series

amplifiers, the green signal indicator illuminates when a signal
(> –40 dBm) is present at the

INPUT

of the amplifier . This indi­cator is before the level control, so it can be used to trouble­shoot wiring problems within a system. No green glow, no
signal is reaching the amplifier!

Power: The green Power indicator turns on when your

CE-

Series

amp has been turned on and has power.

Page 28

CE-Series

Amps with an Attitude!

Controls

Level: You can adjust each channel’s output using the level
control on the front of the amplifier. To decrease the level, ro­tate the control counter-clockwise (to “

∞”). To increase the

level, rotate it clockwise (to 0). The level control knob may be
pulled from the front panel and the holes plugged with the
supplied caps, if you wish, to minimize tampering of control
settings.

Fig. 3.2 Back

Panel Controls

Power: The power switch is located on the front panel so you
can easily turn the amplifier on or off. When the switch is de­pressed left, the amp is off. If you ever need to make any wir­ing or installation changes, don’t forget to also disconnect the
power cord.

Please follow these steps when first turning on your amplifier:

1 Tu rn down the level of your audio source. For example,

set your mixer’s volume to “

∞” (off).

2 Turn down the amplifier’s level controls (counter-clock-

wise to

“∞”).

3 T urn on the power switch. The power indicator beside the

switch will turn on.

4 After the Power light turns on, test the operating range of

your input by turning up the level of your audio source to
the highest possible operating level before distortion. Y ou
should notice the green signal indicators glowing on your
amplifier .

Input Sensitivity: A two-position Input Sensitivity switch is lo­cated on the back panel near the input connectors. Your am­plifier is shipped from the factory with this switch set to the

1.4-V position. At this setting, a 1.4-volt input signal will drive
the amplifier to full power into an 8-ohm load when the level
controls are turned to maximum. The input sensitivity can also
be set to a fixed voltage gain of 26 dB.

The input sensitivity setting is a function of amplifier gain. You
will want to match this setting with the output capability of the
mixer or equipment sending the drive signal to the amplifier.
The 1.4-V position corresponds to a +4 dBu level. This is the
level that most professional gear operates at. The 26-dB posi­tion is a fixed gain position, meaning the amplifier provides a
fixed voltage gain of 20 (or 26 dB: 1 volt in, 20 volts out). This
position works best with output levels of +10 dBu (2.5 volts
RMS) or more. Some brands of DJ mixers, in particular, have
output levels in this range. Selecting the correct sensitivity will
allow your equipment to operate at its optimum level and im­prove the signal-to-noise of the system.

Mode: Bridge-Mono Mode combines the two amplifier output
channels into a single mono channel with twice the voltage of
a single stereo channel. This means the output will be much
more powerful! It does this by bridging the outputs, and it re­quires special output wiring. Do NOT use the negative (1–,
2–) outputs when the Bridge-Mono Mode is selected. Con­necting anything to the negative terminals may result in a visit
by the Polarity Police (see Section 2 for more information).
When Bridge-Mono Mode is selected, only the Channel 1 level
control and the Channel 1 signal LED will work. If the Channel
2 input is wired, the Channel 2 level control should be turned
to “

∞” (counter/anti-clockwise) to prevent distortion.

On the other hand, an unbalanced circuit usually holds one
leg at ground potential, while the second leg is “hot.” Unbal­anced line is less expensive, but is much more susceptible to
noise, and is not usually used in professional applications. For
the cleanest signal, without unwanted hum and buzz, bal­anced line is always recommended. It is especially helpful if
you have a long cable run (over 10 feet (3 m)), since noise is
easily introduced into long, unbalanced lines.

Balancing the Line

A balanced audio circuit typically will have both positive (+)
and negative (–) legs of the circuit isolated from the ground
circuit. These balanced legs exhibit identical impedance char ­acteristics with respect to ground, and may also carry the au­dio signal at the same level, but with opposite polarities. This
results in a line that offers excellent rejection of unwanted
noise.

The Dastardly Duo: Dr. Hum and Mr. Buzz

If you have noticeable hum or buzz in your system, you may
want to check your cable connections to see if the unwanted
noise is being introduced via a ground loop. To determine the
proper wiring, first check whether the output from your source
is unbalanced or balanced (if you don’t know , refer to the unit’s
back panel or instruction manual). If the source is balanced,
refer to Figure 4.3; if it is unbalanced refer to Figure 4.4. Next,
determine if the source’ s power cable is floating (ungrounded,
2-prong) or grounded (3-prong). Finally, if the source is unbal­anced, check the type of wiring: twin-lead or single coax.

Hum and Buzz Tips

1. It is imperative that all of your electrical equipment share the
same power ground reference.

2. Unless you are interfacing to a microphone, the shield of the
cable should only be connected at one end. (See Fig. 4.2.)

3. Do not pass signal ground between electrical components in
a grounded source system.

4. If you wish to avoid ground loops, it doesn’t matter if you lift the input or output
signal ground for your system topology, just be consistent. Personally I prefer to lift
the input signal ground and it has always been successful...so far!

5. NEVER use a ground lift adapter to lift the power ground on a 3-wire AC cord; this
is not its intended purpose. It is better to have it SAFE than SILENT!! Look for the
true source of the noise.

6. Even when interfacing to an unbalanced load, it is preferable to use two-conductor
shielded cable.

7. Get rid of the lighting company!

Fig. 4.3 Balanced Input Wiring

Check Figure 4.4 (following page) to see if your cable has been
wired with the proper shield and gr ound connection. If the ca­bling is incorrect, you may be able to avoid the ground loop
(and associated hum) by plugging all of your equipment into
the same AC circuit (on the same breaker). If this is impracti­cal, you will need to fix the cable to match the appropriate
illustration. Or you may want to simply replace the offending
cable with a commercially manufactured cable of the appro­priate type.

Crown SST Module

On the back panel of your amplifier, you will notice that the
input module is removable. This module may be replaced by
other SST (System Solution Topologies)—modules which will
customize the equipment to better serve your needs. One such
SST is an electronic crossover network designed to improve
the fidelity of your system. While not all applications will require
such improvements, the following should help you decide if
this crossover SST is right for you.

Why Biamped?—Crown has developed a truly professional
crossover that simply plugs into the input slot on the back panel
of the

CE-Series

amplifiers. Extremely easy to install and set
up, the crossover uses hard-wired pr ecision components that
stay at the frequencies you have selected for consistent band­width control.

When you use Crown’ s SST plug-in crossover to split the power
drive to the loudspeaker components, you gain a wide range
of advantages, including:

1. Increased gain because the insertion loss of passive
crossover networks is eliminated.

2. Consistent power bandwidth: power bandwidth is
changed in multi-way passive systems if transducers
change impedance or vaporize (blow up).

3. Levels can be matched more accurately to the compo­nents.

4. Quicker troubleshooting.

5. Improved dynamic range.

6. Better protection of components due to steep 24-dB/oc­tave filters.

Fault Monitoring

The Fault (RJ11) jack, which looks like a telephone plug, is
located on the back of your CE amplifier. It gives you an easy
way to remotely monitor the amplifier’s fault status. T o set up a
circuit that will cause an LED to light whenever a fault status
occurs, you can simply use the suggested circuit shown in
Figure 5.2.

When using this circuit, the LED will glow whenever the ampli­fier is in one of four states: a channel’s heatsink has reached
its temperature limit, the transformer has reached its tempera­ture limit, the amplifier has just been turned on and is in its
turn-on-delay mode, or the amplifier is turned off.

If you choose to design your own circuit to interface this signal
to your system, note that this RJ jack is polarity sensitive. Pin 2
must be grounded, and Pin 5 must be supplied with a positive
voltage pull up (positive with respect to ground). Refer to Fig­ure 5.3 for RJ jack pin assignments.* The maximum signal that
can be exposed to the fault jack is 35 VDC and 10 mA. Best
results are obtained with 10 mA LEDs.

Handle Kit

Handles complement your amplifier’ s appearance, aid in trans­portation, and the placement or removal from racks. They are
available from Crown’s Parts Department (Part # 125489-1).

T amper-Resistant Hole Plugs

Your

CE-Series

amplifier comes with a set of tamper-resistant
hole plugs, which allow you to “protect” the level controls
against unauthorized adjustment. To use, simply pull off the
control knobs from the front of the amp, and slip the hole plugs
into place (see Figure 5.4). The plugs should slide easily into
position, without forcing. Once in place, the plugs will help to
avoid most accidental or intentional tampering (some situa­tions may require additional security measur es).

To remove the hole plugs, simply pry the plug away from the
amplifier case using a small, flat-blade screwdriver. T o help to
ensure adequate security, the plugs have been designed to
be more difficult to remove than to place into position. If nec­essary, additional hole plugs can be purchased separately
from Crown’s Parts Department (Part # 103234-1).

6 Principles of Operation

For the sake of simplicity, only channel one of the amplifier is
described.

Signal is presented to the CE 1000 and CE 2000 through one
of three connectors when using the standard input module.
Each channel is outfitted with a balanced XLR / phone jack,
and a barrier strip. These connectors are wired in parallel,
which allows daisy chaining when needed. The signal is then
converted from balanced to unbalanced in the Balanced In­put Stage where it also receives RFI protection. Signal then
flows into the Variable Gain Stage where the front panel level
controls are allowed to affect the gain. This stage also pro­vides the necessary scaling to change the amplifier’s overall
input sensitivity when the rear mounted input sensitivity switch
is moved.

Following this stage, the signal is put under the control of a full­time compressor circuit comprised of a symmetrical window
detector , a buffer amplifier, and the gating op amp which uses
several small components to set the compressor’s attack and
decay characteristics. The actual compressing is accom­plished by an opto-isolator which affects the gain in the signal
path.

BOOTSTRAP

The signal next enters the main amplifier error amp where it is
mixed with a small portion of the output signal in such a way as
to control the amplifier’ s overall output performance.

Warning:

Details of closed loop amplifier design are beyond the scope
of this description and if discussed, would surely put most
readers to sleep!

Following the error amp is the LVA stage, which is where the
low-voltage referenced signal gets translated to the output
high-voltage rails. The last voltage amplifier , in conjunction with
a bootstrapped current source, drives both predrivers and the
bias servo. The bias servo is mounted in such a way as to
translate the output heatsink temperature into a controlled bias
current to prevent thermal runaway and hold the amplifier’s
notch distortion to a minimum.

The predrivers provide enough signal to activate the drivers,
which together operate in the class AB range. For the major
output current requirements, the drivers feed the various num­bers of paralleled output transistors which operate in a class B
mode. This we call the Triple-Deep Darlington Output Stages.
The output transistors are protected by the Time Dependent

Page 42

V oltage & Current circuit. This circuit pr otects the devices from
extending beyond their safe area of operation, but allows the
devices to provide high bursts of peak power with music, al­lowing your amplifier to deliver more punch. When all is said
and done, this amplifier output topology offers a good combi­nation of low quiescent amplifier heating and great distortion
performance at high powers for a reasonable complexity, reli­ability, and value.

All output power is delivered through 4-circuit Speakon

®

con­nectors. These connectors have been wired in such a way as
to allow you the most versatility . The Channel 1 and 2 connec­tors are cross wired so you can cover all options, from dual
cable stereo (typical), to Bridge-Mono in one connector , to run­ning a bi-amp speaker with one amplifier and one cable per
speaker cabinet!

The output relay, in conjunction with input signal mute circuit,
assures the amplifier will be well-behaved during turn on and
off. In the event of an amplifier output failure, a triac will fire
across the offending channel and act to protect your speak­ers.

The turn on delay circuit functions to keep the output relay
open until all the voltages are up and stable, both in the ampli­fier, and in all the components in the system ahead of the am­plifier.

Heatsink temperature is monitored by a thermal probe at­tached to the heatsink. As the temperature rises, the probe
sends a proportional current to the proportional speed fan cir ­cuit which starts the fan. Should the power transformer reach
its maximum safe temperature, an internal thermal switch
opens and the fan circuit turns on full speed to quickly cool

Page 43

CE-Series

Amps with an Attitude!

down the amplifier. It also disconnects the load via the output
relay , removing any output current and further speeding a cool­down cycle. Extra care was taken during the design stage to
set this point both to protect your investment and to to guard
against nuisance tripping.

Whenever the heatsinks or the transformer reach a maximum
temperature, or during the normal turn on delay window, the
front panel Fault LEDs will blink to get your attention.

A modular jack is mounted on the back panel (same type as
used on telephones). Pins 2 and 5 are connected to an opto­isolator which is always in a low-resistance state whenever the
unit is on and happy. Should a fault be detected or should the
amplifier lose AC power , the opto-isolator will change to a high
resistance, allowing the user to remotely detect the status of
the amplifier.

The Signal Presence Indicators tap the signal chain just be­fore the level controls and prior to the power amplifier chain.
They are

not

amplifier output indicators and should only be
used to indicate the presence of signal to the amplifier front
end.

The Clip light is driven from the output of the compressor cir­cuitry and lights to indicate the onset of audible distortion.

The Power LED is driven from the low-voltage supply.
A positive and negative regulator form the ±15-volt power sup-

plies. Add to that the main transformer , a full-wave bridge r ec­tifier, and high energy electrolytics to form the main power
supply. They are protected by the front-panel line circuit
breaker and controlled by the front-panel power switch.

And there my friends you have it, the guts of the CE 1000/CE
2000 from Crown Audio!
