General Connections - CLASSE CA-201 Bedienungsanleitung

THANK YOU FROM EVERYONE AT
CLASSÉ
Thank you for purchasing the CLASSÉ CA-201
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 CA-201 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 CA-201 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 CA-201 is
located at the front-center of the unit. Ideally,
a few feet should separate this area from
components which 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 CA-201 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.
Stereo
Input and output connectors are clearly
marked on the back of the amplifier. Left/Right
connections are oriented from the front of the
unit. Stereo output connections are marked
above the connectors. Switch stereo/mono
switch to STEREO position. (The CA-201 is
preset at the factory for STEREO.)
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. DO NOT
OVERTIGHTEN the output connectors as this can
result to damage your unit.
Mono
Please read through the previous Stereo section
for general notes on securing good connections,
and safety tips. If the unit has been previously
used in stereo, make sure it is OFF, and remove
all connections, including the AC line cable.
Make sure the STEREO/MONO switch is
switched to the MONO position.
NOTE: The Stereo-Mono switch will not operate
if the amplifier is turned on, you will NOT be able
to change from one mode to the other, as the
mode is "locked" while the amplifier is on.
The MONO "Input" is the "left channel input",
as marked. The unused right channel input is
automatically disconnected. Correct output
phase MONO connections are marked below
the connectors.
Repeat the above MONO settings and
connections on the second CA-201 to be
used for the other channel.
Please remember that the negative output
connection of a bridged amplifier is NOT a
ground. Do not use a "common ground" switch-
box set-up. Do not use with electronic crossovers
which have a common ground. Connecting two
bridged amplifiers to a common ground device
of any sort will cause the amplifiers to fail.
IR Out and In:
The CA-201 may also be turned on and off using
our SSP-75 Surround Sound Processor, utilising
the IR OUT and IN jacks. To turn on your CA-201
with the SSP-75, Disconnect you CA201 from
the AC line completely, open the top cover and
locate the 4 internal jumpers inside the CA-201
(see fig. 2) beside the Mosfet fuses. When facing
the amplifier from the front, remove the jumper
located completely to the right and save this
jumper. Re-install the top cover. Install a mini jack
into IR IN at the back of the CA-201 and plug
the other end of the mini jack into the 5VDC
mini jack at the back of your SSP-75. When the
Standby button of the SSP-75 is pressed, it will
now activate the turn on turn off circuitry of
your CA-201. Several amplifiers may be turned
on automatically in sequence or all at once,
depending upon the configuration of the jumper
settings inside the unit (see fig.2) alongside the
Mosfet fuses. The table in Figure 3 tells you
which jumper should be inserted or removed
to obtain the correct sequence on which you
will want your amplifier to turn on.
