OWNER'S MANUAL
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 CAV-150 multi-channel 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 have also been included:
1)Detachable linecord.
2)Allen key for top plate.
Please report any damage or missing parts to your dealer as soon as possible.
Place the CAV-150 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 CAV-150 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 CAV-150 has one line fuse (internal), the rating of which should be as follows:
LINE VOLTAGE |
FUSE RATING |
100 or 120 V.A.C. |
8 AMP SLOW BLOW 125 or 250 volts |
220 or 240 V.A.C. |
6 AMP SLOW BLOW 250 volts |
INTERNAL RAIL FUSES: |
|
The CAV-150 is designed with each channel protected by one pair of internal fuses for positive and negative rails (see fig-1b page 8)

GENERAL CONNECTIONS AND OPERATION:
A.C. LINE: 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 WARRANTY SECTION OF THIS OWNER'S MANUAL.
REGULAR INPUTS:
The CAV-150 is factory set for REGULAR use. Connect the regular interconnect to the RCA input jacks, for Channel-1 and Channel-2 make sure the Regular/Balanced switch is set to position marked "Regular" (down) which selects REGULAR inputs for both channels-1 and channel-2. (The Balanced XLR input jacks are automatically disable).
BALANCED INPUTS:
Balanced inputs are available to Channel-1 and Channel-2 only. For use with balanced preamplifier other than Classé, the wiring of the 3-pin XLR connectors must be matched to that of the Classé wiring configuration, which are as follows:
PIN 1: Ground
PIN 2: Positive (non-inverting) signal
PIN 3: Negative (inverting) signal
If the pin configuration of the preamplifier differs from above, the balanced interconnects must be modified to accommodate the different preamp. Make sure the Regular/Balanced switch is
