Classe Audio CA-101 - Manual (Page 4)

CONNECTIONS FOR REGULAR OR
BALANCED INPUTS
The CLASSÉ CA-101 power amplifier is equipped
with both regular and balanced inputs. Either
one may be used SEPARATELY BUT NOT
SIMULTANEOUSLY. The balanced inputs must be
connected to a preamplifier which has balanced
main outputs, and balanced interconnects with
“XLR” connectors are also required. Regardless
of the amplifier inputs used, stereo or mono
operation is still possible on the CA-101.
REGULAR INPUTS
Switch the REGULAR/BALANCED switch to the
position marked “REGULAR” /\. (The amplifier is
factory set for regular use.) Connect the regular
interconnects to the RCA input jacks on the rear
panels of the CA-101. The balanced connectors
are automatically disabled.
BALANCED INPUTS
Switch the REGULAR/BALANCED switch to the
position marked “BALANCED” V. A balanced
preamplifier and balanced interconnects are also
required. For use with balanced preamplifiers
other than Classé, the wiring of the 3-pin XLR
connectors must be matched to that of the
CLASSÉ CA-101 which are wired as follows:
• PIN 1: GROUND
• PIN 2: POSITIVE (NON-INVERTED) SIGNAL
• PIN 3: NEGATIVE (INVERTED) SIGNAL
If the pin configuration of the preamplifier differs
from above, the balanced interconnects must be
modified to accommodate the different preamp.
Having confirmed the correct connections, plug
the XLR connectors of the balanced interconnects
into the locking XLR connectors on the rear panel
of the CA-101. (To remove the connectors, press
the tab above the connector.)
PROTECTION CIRCUIT
The Classé CA-101 is equipped with rail fuses to
protect the output drivers (GBD4, 4 amps fast
blow. fig.2) . In the event that a short circuit or
other problems occur at the output of the
amplifier, one or more of these fuses may blow
in an attempt to protect the amplifier. In addition
to the fuses, the unit has a circuit for the
detection of unusual distortion characteristics
and/or DC content in the incoming audio signal.
There is also an AC line fuse protecting the unit,
it is located at the back of the unit, immediately
to the right side of the AC receptacle (see fig.1).
If the protection circuit of the unit is triggered or
any of the fuses has blown, the FRONT PANEL
POWER LED will go to FLASHING GREEN. IF THE
PROTECTION CIRCUIT HAS BEEN TRIGGERED,
TURN THE CA-101 OFF. After the situation which
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 FUSES AND RE-STARTING
THE UNIT WITHOUT CHECKING FOR
COMPONENT FAILURE COULD RESULT IN
FURTHER, SERIOUS DAMAGE TO VITAL
COMPONENTS IN YOUR AMPLIFIER.
