Mono Power Amplifier

CLASSÉ DESIGN PHILOSOPHY
1. REPEATED LISTENING DESIGN SESSIONS:
Fine tuning of sound by exchanging and mixing of parts (transistors, capacitors, wiring, PCB
boards etc.), and adjusting many specific operating voltages within proper engineering ranges,
producing an overall sonic recipe giving the most natural harmonic realism of music typical of
instruments in a live performance.
2. UPGRADABLE SINGLE CIRCUIT DESIGNS:
All Classé products (all preamps and all amps) share exactly the same circuit (excluding moving
coil and moving magnet phono circuits). This means all amplifiers and all high level circuits of
the preamps are the same. The same circuit is tailored to different power levels etc. Differences
between less expensive models and more expensive models are parts quality and compliment,
power supply extravagance and the amount of filtering etc., as well as features and packaging.
This means that for years Classé has been constantly fine tuning and upgrading this circuit and
its application, thus reaching a very high level of understanding and musical achievement which
benefits all models - least expensive, most expensive, preamps and amplifiers alike.
3. EXTREME LONG LIFE IN REAL WORLD CONDITIONS:
Choosing the best attainable quality parts and materials combined with the advantages of the two
above-mentioned areas provides Classé owners with years of proven trouble free reliability and
musical enjoyment

UNPACKING & SET-UP
Your CLASSÉ CAM200 power amplifier is packed in high density, semi-rigid foam placed
in a special cardboard box. Take it out of the plastic bag and inspect the unit for any concealed
damage. Apart from this owner's manual, please ensure the following has also been included:
1) Detachable A.C. linecord
Please report any damage or missing parts to your dealer immediately.
Place the CAM200 at or near its final set-up position, allowing 8 inches at the rear for
tightening the speaker output connectors. For optimum sonic performance, we recommend the
optional CLASSÉ REFERENCE A.C.
. Consult your dealer regarding this accessory.
The power transformer in the CAM200 is located at the front center of the unit. Ideally, a
few feet should separate this area from components which are potentially could pick up hum. These
include preamplifiers, turntables, and interconnect cables. In terms of providing adequate airspace
for cooling, a good rule of thumb is to allow 6 inches above and 3 inches on each side of the unit.
Check the Serial Number sticker on the back of the unit for the correct operating voltage.
The CAM200 has one external AC fuse, the rating of which should be as follows:
LINE VOLTAGE FUSE RATING
100 or 120 V.A.C. 10 AMP SLOW-BLOW 125 or 250 volts
220 or 240 V.A.C. 8 AMP SLOW-BLOW 250 volts

GENERAL CONNECTIONS
A.C. LINE
Insert the linecord into the A.C. receptacle on the rear of the unit. PLEASE MAKE SURE
YOU HAVE PREVIOUSLY HOOKED UP THE SPEAKERS AND PREAMPLIFIER TO
YOUR AMPLIFIER BEFORE CONNECTING THE AC POWER CORD TO THE
AMPLIFIER.
CAUTION: SAFETY INSTRUCTIONS
DISCONNECT AC LINE CABLE WHILE MAKING ALL CONNECTIONS. "FLOATING THE
GROUND” OR DEFEATING THE GROUND ON A 3-PRONG LINECORD MAY CREATE
A SHOCK HAZARD. CONNECT ALL INTERCONNECT CABLES BETWEEN THE
ELECTRONICS BEFORE CONNECTING THE A.C. LINECORDS TO THE WALL
OUTLETS. THIS WILL REDUCE THE POTENTIAL SHOCK HAZARD.
Input and output connectors are clearly marked on the back of the amplifier. Use only high
quality interconnect and loudspeaker cables, and make all connections tight. If the RCA input plugs
are loose, remove them and pinch down the ground leaves slightly with pliers. Observe correct
phasing of the loudspeaker connections, and tighten.
Caution:
1) Do not over tighten the output connectors as this can result to damage your
unit.
2) Do not use speaker system that has common ground with this amplifier.

IR OUT and IN
The CAM200 can be turned ON /OFF using a +5VDC trigger or with remote control code via the
IR IN jack located at the rear of the unit. The IR OUT is the loop out of the incoming signal from IR
IN. The IR OUT has it own buffer to isolate between IN and OUT.
Your CAM200 is factory set as being the 1st amp (AMP 1) to be turned on in sequence. To re-
program your unit so that it would be the 2nd, 3rd, 4th, 5th or 6th amps to be turned on in sequence you
have to follow this procedure.

IR OUT and IN (Continued)
The remote control system is RECS80 with the system code 5 and the command codes is as follows:
AMP1 _____ 24 AMP4 _____ 27
AMP2 _____ 25 AMP5 _____ 34
AMP3 _____ 26 AMP6 _____ 35
These command codes will toggle the CAM200 ON/OFF. To turn all six of the amplifier ON
and OFF the following code should be used:
ALL ON_____08 ALL OFF_____9

CONNECTIONS FOR REGULAR OR BALANCED INPUTS:
The CLASSÉ CAM200 power amplifier is equipped with both regular and balanced inputs,
either one may be used SEPARATELY, BUT NOT SIMULTANEOUSLY. Be sure that the CAM200 is
OFF before changing any connections.
When the amplifier is shipped from Classé, there is a jumper at the balanced input (XLR)
between pin 1 and 3. To use the amplifier in single ended mode simply connect a single ended inter-
connect from the preamplifier to the RCA input of the CAM200.
To use the CAM200 in balanced mode, remove the single ended interconnect and remove
the jumper at the XLR; please keep this jumper for later use; connect the preamplifier to the
CAM200 using balanced interconnect.
The XLR connector of the CAM200 is configured as below
PIN 1: DRAIN
PIN 2: POSITIVE (NON-INVERTED) SIGNAL, “HOT”
PIN 3: NEGATIVE (INVERTED) SIGNAL
All Classé preamplifiers and amplifiers have the same pin out configuration of the XLR. Other
manufacturers may have different XLR pin out configuration please contact the manufacture if you
wish to maintain absolute phase throughout your system when connecting Classé’s equipment with
other manufacturer’s equipment.
Having confirmed or established the correct phasing, be sure the amplifier is off, then plug
the XLR connector of the balanced interconnect into the locking XLR connector on the rear panel of
the CAM200. Push the connectors in until the locking mechanism clicks. To remove the connectors,
press the tab above the connector while pulling gently on the connector body.

PROTECTION CIRCUIT
The Classé CAM200 equipped with a rail currents sensors to protect the output drivers under
extreme condition such as short output, and Mosfet fuses (2AG 1/2 PT, 1/2 amp fast blow) to protect
the Mosfets, which are used as pre-drivers for the output stage of the amplifier.
Also the CAM200 has an output DC sensor; this will put the CAM200 on protection mode in the
event DC occurs at the output of the amplifier or heavy clipping of output signals. There is also an
AC line fuse protecting the unit. It is located at the back of the unit immediately above the AC
receptacle (see fig.1, page 10).
If the protection circuit of the unit is triggered or any of the fuses has blown, the FRONT
PANEL POWER LED will go to BLINKING GREEN, indicating a “fault” condition.
WHEN THE PROTECTION CIRCUIT HAS BEEN TRIGGERED, UNPLUG THE AMP
FROM THE OUTLET. Check for any possible event that might trigger the protection circuitry such
as short output, blown Mosfet fuses, etc. After the situation which has triggered the protection
circuit has been clearly identified and corrected, attempt to re-start the unit. IF THE UNIT STILL
GOES INTO PROTECTION MODE, OR IF IT APPEARS THAT PROTECTION FUSES DID
BLOW, CONTACT YOUR LOCAL DEALER. DO NOT TRY TO CHANGE A BLOWN FUSE.
REPLACING A FUSE WITHOUT CHECKING FOR COMPONENT FAILURE COULD
RESULT IN FURTHER, SERIOUS DAMAGE TO VITAL COMPONENTS IN YOUR
AMPLIFIER. CONTACT YOUR LOCAL DEALER or Customer Service at the Classé Audio,
Inc ---(514) 636 63 84.
