General Connections - CLASSE CAM350 Bedienungsanleitung

THANK YOU FROM EVERYONE AT
CLASSÉ
Thank you for purchasing the Classé CAM350
mono power amplifier.
We take great pride in offering components
that combine exceptional sonic performance and
long-term reliability. To do that, we have invested
in extraordinary design and manufacturing
facilities. We trust that you will enjoy your
purchase for many years to come.
CLASSÉ DESIGN PHILOSOPHY
All of our components benefit from the same
rigorous design goal: All Classé products must
reproduce music with the harmonic and spatial
integrity typical of fine instruments heard in a
live, unamplified performance.
Single Circuit Design
To this end, we make extensive use of
carefully optimized versions of the same basic
circuit precisely matched to specific power
requirements. This means that all Classé line
level components and power amplifiers benefit
from years of refinement. However, our efforts
do not stop here.
Listening: The Critical Design Element
Once we determine general circuit values
for a particular application, we listen carefully
while exchanging and mixing different parts
(transistors, capacitors, wiring, PC boards, etc.)
and adjusting specific operating voltages within
proper engineering ranges.
Extended Real-World Lifespan
Every Classé component, even the most
affordable, benefits from our painstaking
approach to design parameters. The result is an
optimum balance between the often-conflicting
demands of exceptional performance and long-
term reliability. Our most expensive components
gain from even tighter tolerance parts and highly
segmented and exceptionally robust power
supplies with large reserve-current capabilities.
Our Pride in Manufacturing, Your Pride
in Ownership.
We build all of our components to the highest
possible standards. From multi-layer glass-epoxy
circuit boards, the full sized power-supplies, and
the massive faceplates, every Classé product is
a tribute to both the science and art of sound
reproduction. We hope that you derive as much
pleasure and satisfaction in using your Classé as
we did in producing it.
UNPACKING & SET-UP
Your CLASSÉ CAM350 power amplifier is packed
in high den-sity, semi-rigid foam placed in a
special cardboard box. To remove the unit, open
and spread all the top flaps of the box and by
its sides, lift out the entire unit and put it on a
large flat surface. 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:
• Detachable A.C. linecord
Please report any damage or missing parts to
your dealer immediately.
Place the CAM350 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. LINECORD.
Consult your dealer regarding this accessory.
The power transformer in the CAM350 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
CAM350 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:
• Do not over tighten the output connectors
as this can result to damage your unit.
• Do not use speaker system that has common
ground with this amplifier.
IR Out and In:
The CAM350 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 CAM350 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 the procedure
outlined in fig 1.
The remote control system is RECS80 with the
system code 5 and the command codes are
as follows:
AMP1 _____ 24 AMP4
AMP2 _____ 25 AMP5
AMP3 _____ 26 AMP6
These command codes will toggle the CAM350
ON/OFF. To turn all six of the amplifier ON and
OFF the following code should be used:
ALL ON _____ 08 ALL OFF _____
CONNECTIONS FOR REGULAR OR
BALANCED INPUTS:
The CLASSÉ CAM350 power amplifier is
equipped with both regular and balanced inputs,
either one may be used SEPARATELY, BUT NOT
SIMULTANEOUSLY. Be sure that the CAM350
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 CAM350.
To use the CAM350 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 CAM350 using balanced interconnect.
The XLR connector of the CAM350 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
