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 M-700 power amplifier is packed in high density, 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:
1) Detachable linecord
2) Allen key for top plate
3) Nut driver for CLASSÉ output bolts
Please report any damage or missing parts to your dealer as soon as possible.
Place the M-700 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 M-700 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 M-700 has only one fuse, the rating of which should be as follows:
LINE VOLTAGE FUSE RATING
100 or 120 V.A.C. 8 AMP FAST BLOW 125 or 250 volts
220 or 240 V.A.C. 4 AMP FAST BLOW 250 volts

GENERAL CONNECTIONS
A.C. LINE
Making sure the power switch is in the off position, insert the linecord into the A.C.
receptacle on the rear of the unit.
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. SEE ALSO THE M-700 WARRANTY SECTION OF THIS OWNER'S MANUAL.
Use only high quality interconnect and loudspeaker cables, and make all connections tight. If
the input plugs are loose, remove them and pinch down the ground leaves slightly with pliers.
Tighten the output bolts with the nut driver supplied, placing the wire or lug between the washer and
large chassis nut. Observe correct phasing of the loudspeaker connections.
Please remember that the negative output connection of a bridged amplifier is NOT a
ground. Do not use a "common ground" or switchbox set-up. Do not use with electronic crossovers
which have a common ground.
-6-
CONNECTIONS FOR REGULAR OR BALANCED INPUTS:
The CLASSÉ M-700 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.
REGULAR INPUT
The amplifier is factory set for regular use. Connect the regular interconnects to the RCA
input jack on the rear panel of the M-700, and make sure the toggle switch lever is closest to the
position marked REGULAR. The balanced XLR connector is automatically disabled.
BALANCED INPUT
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 M-700 which is wired as follows:
PIN 1: GROUND
PIN 2: POSITIVE (NON-INVERTED) SIGNAL
PIN 3: NEGATIVE (INVERTED) SIGNAL
If the pin configuration on 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 connector on the rear panel of the M-700. (To remove the
connectors, press the tab above the connector.) Disconnect the M-700 from the A.C. line. Make
sure the toggle switch lever is switched from the REGULAR to the BALANCED position. This
activates the balanced inputs and disables the regular inputs.
