welcome

Congratulations on your purchase of a Crest Audio CC™ Series power
amplifier. Designed for years of reliable, flawless operation under rigor
ous use. The Crest CC Series amplifiers offer the sonic superiority and
unsurpassed reliability for which Crest Audio is famous, while remaining
surprisingly compact. Advanced technology and extensive protection cir
cuitry allow operation with greater efficiency into difficult loads and power
conditions. The ACL™ (Automatic Clip Limiting) circuit ensures trouble­free operation into loads as low as 2 ohms. The Automatic Clip Limiting
circuits protect drivers and ensure that sonic integrity is maintained, even
in extreme overload conditions. Crest Audio’s high-efficiency designs use
tunnel-cooled heat sinks and variable speed DC fans. This cooling topology
maintains a lower overall operating temperature, resulting in longer output
transistor life. Model CC 4000, CC 2800, and CC 1800 power amplifiers
use Crest Audio’s innovative “Power Density” circuitry and packaging.

For your safety,

unpacking

CCTM owner’s manual

Upon unpacking, inspect the amplifier. If you find any damage, notify your supplier
immediately. Only the consignee may institute a claim with the carrier for damage
incurred during shipping. Be sure to save the carton and all packing materials. Should
you ever need to ship the unit back to Crest Audio, one of its offices, service centers,
or the supplier, use only the original factory packing. If the shipping carton is unavailable,
contact Crest to obtain a replacement.

mounting

CC Series amplifiers will mount in standard 19" racks. Rear mounting ears are also
provided for additional support, which is recommended in non-permanent installations
like mobile or touring sound systems. Because of the cables and connectors on the
rear panel, a right angle or offset screwdriver or hex key will make it easier to fasten
the rear mounting ears to the rails.

connecting power

CC Series amplifier power requirements are rated at 1/8th power (typical music
conditions) and 1/3
rent draw rating is limited only by the front panel circuit breaker. Consult the speci
fications in the Appendices section for figures on the current that each amplifier will
demand. Make sure the mains voltage is correct and is the same as that printed on
the rear of the amplifier. Damage caused by connecting the amplifier to improper AC
voltage is not covered by any warranty. Unless otherwise specified when ordered,
Crest amplifiers shipped to customers are configured as follows:

cooling requirements

The CC™ Series amplifiers use a forced-air cooling system to maintain a low, even
operating temperature. Air is drawn into the amplifier by fan(s) on the rear panel,
courses through the cooling fins of the tunnel-configured channel heat sink(s), and then
exhausts through the front panel grille. If a heat sink gets too hot, its sensing circuit
will open the output relay, disconnecting the load from that particular channel. The CC
1800 utilizes one common heat sink and a single fan, but retains the separate circuitry.
It is important to have an adequate air supply at the back of the amplifier and enough
space around the front of the amplifier to allow the cooling air to escape. If the amp
is rack mounted, do not use doors or covers on the front of the rack; the exhaust air
must flow without resistance. If you are using racks with closed backs, use fans on the
rear rack panel to pressurize the rack and ensure an ample air supply.

operating precautions

Make sure the mains voltage is correct and is the same as that printed on the rear of
the amplifier. Damage caused by connecting the amplifier to improper AC voltage is
not covered by any warranty. See the Connecting Power section for more information
on voltage requirements.

™

Although the CC Series amplifiers have AUTORAMP
level gradually after the output relay closes, it is always a good idea to have the gain
controls turned down during power-up to prevent speaker damage if there is a high
signal level at the inputs. Whether you buy or make them, use good-quality connections,
input cables and speaker cables, along with good soldering technique, to ensure
trouble-free operation. Most intermittent problems are caused by faulty cables.

connecting inputs

Input connections are made via the 3-pin XLR (pin 2+) or 6.3 mm plug “Combi”
connectors on the rear panel of the amplifier. The inputs are actively balanced. The
input overload point is high enough to accept the maximum output level of virtually
any signal source.

connecting outputs

All models have two output (speaker) connections per channel. Cables can be
connected with banana plugs, spade lugs, or bare wire to the five-way binding posts.
The preferred method is connection via the Speakon connectors.

switches and controls

AC Power Switch/Circuit Breaker

1

The CC Series amplifiers have a combination AC switch/circuit breaker
on the front panel. If the switch shuts off during normal use, push it
back to the ON position once. If it will not stay on, the amplifier needs
servicing.

Input Attenuators

2

Whenever possible, set the attenuators fully clockwise to maintain
optimum system headroom. The input attenuator controls (one for
channel A, one for channel B) located at the front panel adjust gain for
their respective amplifier channels in all modes. See the specifications
at the end of this manual for standard voltage gain and input sensitivity
information.

indicators

CC Series amplifiers feature four front panel LED indicators per channel: ACL
(Automatic Clip Limiting), Signal, Temp, and Active. These LED indicators inform
the user of each channel’s operating status and warn of possible abnormal condi
tions.

ACL LED

3

A channel’s ACL LED will light at the onset of clipping. If the LED’s are

flashing quickly and intermittently, the channel is just at the clip
threshold, while a steady, bright glow means the amp is clip limiting,
or reducing gain to prevent severely clipped waveforms reaching
the loudspeakers. See the Automatic Clip Limiting section for more
information. During initial power up the ACL LED will light indicating

When operating in the bridged
mode, both attenuators must
be in the same position so the
speaker load will be equally
shared between the channels.
See the section on Bridged
Mono Operation for more
information and precautions.

Signal LED

4

This LED lights when its channel produces an output signal of about
4 volts RMS or more (0.1 volt or more at the input, with 0 dB
attenuation and standard x40 voltage gain). It is useful in determining
whether a signal is reaching and being amplified by the amplifier.

Temp LED

5

The Temp LED lights to indicate that the channel’s output relay is open,
disconnecting the speaker(s) due to an overheating condition. Once the
channel temperature has returned to safe operating conditions the LED
will turn off, the channel's output relay will close, and the speaker(s) will be
reconnected.

Active LED

6

The Active LED indicates that its channel’s output relay is closed and the
channel is operational. It lights under normal operation and remains on even
when the channel is in Automatic Clip Limiting or ACL gain reduction. These
are protection features which leave the output relay closed. If the Active LED
goes off, there is no signal at the output connectors.

stereo

For stereo (dual channel) operation, turn the amplifier off and set the mode
select switch to the stereo position. In this mode, both channels operate
independently of each other, with their input attenuators controlling their
respective levels. Thus, a signal at channel A’s input produces an amplified
signal at channel A’s output, while a signal at channel B’s input produces an
amplified signal at channel B’s output.

parallel

For parallel (dual-channel/single input) operation, turn the amplifier off and
set the mode switch in the parallel position; both amplifier channels are
then driven by the signal at channel A’s input. No jumper wires are needed.
Output connections are the same as in the stereo mode. Channel A’s and
channel B’s input connectors are strapped together to allow patching to
another amplifier. Both input attenuators remain active, allowing you to
set different levels for each channel. Power and other general performance
specifications are the same as in the stereo mode.

bridged mono

Both amplifier channels can be bridged together to make a very powerful
single-channel monaural amplifier. Use extreme caution when operating in
the bridged mode; potentially lethal voltage may be present at the output
terminals. To bridge the amplifier, turn the amplifier off and slide the rear
panel amplifier mode select switch to the bridge position. Apply the signal to
channel A’s input and connect the speakers across the hot outputs which are

input of another amplifier.

Unlike the stereo and parallel modes, in which one side of each output is at
ground, in the bridged mode both sides are hot. Channel A’s side is the same
polarity as the input. The minimum nominal load impedance in the bridged
mode is 4 ohms which is equivalent to driving both channels at 2 ohms.
Driving bridged loads of less than 4 ohms will activate the ACL circuitry

protection features

5

CC Series amplifiers incorporate several circuits to protect both themselves and loudspeakers
under virtually any situation. Crest Audio has attempted to make the amplifiers as foolproof as
possible by making them immune to short and open circuits, mismatched loads, DC voltage, and

™

overheating. If a channel goes into the Automatic Clip Limiting or ACL
speaker load remains connected, but clipping percentage or output power are instantly reduced.
When a problem occurs that causes a channel to go into a protection mode, the Temp LED for
that channel will glow. DC voltage on the output, excessive subsonic frequencies, or thermal
overload will cause the channel’s output relay to disconnect the speaker load until the problem is
corrected or the amplifier cools down.

gain reduction mode, the

automatic clip limiting (ACL)

Any time a channel is driven into hard, continuous clipping, the clip limiter circuit will
automatically reduce the channel gain to a level just slightly into clipping, guarding the speakers
against the damaging high power continuous square waves that may be produced. Situations
that may activate the clip limiter include uncontrolled feedback, oscillation, or an improper
equipment setting or malfunction upstream from the amplifier. Normal program transients will
not trigger the clip limiter; only steady, excessive clipping will. The ACL LED will glow brightly
and continuously when limiting occurs.

IGM™ impedance sensing

CC Series amplifiers feature innovative circuitry that allows safe operation into any load.
When an amplifier sees a load that overstresses the output stage, the Instantaneous Gain
Modulation (IGM) circuit adjusts the channel gain to a safe level. This method of output stage
protection is far superior to conventional, brute force type limiting found on other amplifiers.
The IGM circuit is sonically transparent in normal use and unobtrusive when activated.

CCTM owner’s manual

thermal protection

The internal fans will keep the amplifier operating well within its intended temperature range
under all normal conditions. If a channel’s heat sink temperature reaches 75°C, which may
indicate an obstructed air supply, that channel will protect itself independently by disconnect
ing its load and shutting down until it has cooled. During this time, the channel’s Temp LED
will glow, the Active LED will go out, the ACL LEDs will stay lit and the cooling fans will run
at high speed. The CC 1800 utilizes one common heat sink and single fan, but retains the
separate circuitry.

short circuit

If an output is shorted, the IGM and thermal circuits will automatically protect the amplifier. The
IGM circuit senses the short circuit as an extremely stressful load condition and attenuates the
signal, protecting the channel’s output transistors from over current stress. If the short circuit
remains, the channel will eventually thermally protect itself by disconnecting the load.

DC voltage protection

If an amplifier channel detects DC voltage or subsonic frequencies at its output terminals, its
output relay will immediately open to prevent loudspeaker damage.

protection features

turn-on/turn-off protection

At power-up, the amplifier stays in the protect mode, with outputs disconnected, for
approximately six seconds while the power supplies charge and stabilize. While the output
relays are open, the ACL LEDs light. When power is removed, the speaker loads immediately
disconnect so that no thumps or pops are heard.

AUTORAMP™ signal control

Whenever a CC Series amplifier powers up or comes out of a protect mode, the AUTORAMP
circuit activates. While the speakers are disconnected, the AUTORAMP circuit fully attenuates
the signal. After the output relay closes, the signal slowly and gradually raises up to its set level.
The AUTORAMP Signal Control circuit has some important advantages over conventional
instant-on circuits:

5

1. If a signal is present during power-up (or when coming out of protect), the speakers are
spared a sudden, potentially damaging burst of audio power.

2. Because the gain is reduced until after the output relay closes, no arcing occurs at the
contacts, thereby extending their useful life.

p. 11

safety

speaker protection

All loudspeakers have electrical, thermal and physical limits that must be observed to prevent
damage or failure. Too much power, low frequencies applied to high frequency drivers, severely
clipped waveforms, and DC voltage can all be fatal to cone and compression drivers. The Crest
Audio CC Series amplifiers automatically protect speakers from DC voltages and subsonic
signals. For more information, see the section on Protection Features. Mid- and high-frequency
speakers, especially compression drivers, are highly susceptible to damage from overpowering,
clipped waveforms, or frequencies below their rated passband. Be extremely careful that the
low and mid bands of an electronic crossover are connected to the correct amplifiers and
drivers and not accidentally connected to those for a higher frequency band. The amplifier’s
clipping point is its maximum peak output power, and some of the higher power Crest Audio
CC Series amplifiers can deliver more power than many speakers can safely handle. Be sure
the peak power capability of the amplifier is not excessive for your speaker system.

To ensure that the speakers never receive excessive power and that the amplifier never clips,
use a properly adjusted external limiter (or a compressor with a ratio of 10:1 or higher) to
control power output. In systems with active electronic crossovers, use one for each frequen
cy band. The clip limiter will automatically limit the duration of continuous square waveforms
applied to the speakers. The amplifier will, however, allow normal musical transient bursts to
pass. Some speaker systems are packaged with processors that have power limiting circuits
and should not require additional external limiting.

Fuses may also be used to limit power to speaker drivers, although as current-limiting (rather
than voltage-limiting devices) they are an imperfect solution. As the weakest links, fuses only
limit once before needing replacement. Some poor quality fuses have a significant series
resistance that could degrade the amplifier’s damping of the speaker’s motion and may even
deteriorate the system’s sound quality. If you elect to use fuses, check with the speaker manu
facturer to determine the proper current rating and time lag required.

CCTM owner’s manual

-

-

Do not drive any low-frequency speaker enclosure with frequencies lower than its own tuned
frequency. The reduced acoustical damping could cause a ported speaker to bottom out even
at moderate power. Consult the speaker system specifications to determine its frequency
limits.

amplifier maintenance and user responsibility

A CC Series amplifier requires no routine maintenance and should never need any
internal adjustment during its lifetime. Your CC Series amplifier is very powerful and can
be potentially dangerous to loudspeakers and humans alike. It is your responsibility to
read the Important Precautions section in the front of this manual, and to make sure that
the amplifier is installed, wired and operated properly. Many loudspeakers can be easily
damaged or destroyed by overpowering, especially with the high power available from a
bridged amplifier. Read the Speaker Protection section and always be aware of the speaker’s
continuous and peak power capabilities.
