1 Welcome

Congratulations on choosing a Power Base amplifier. Power Base amplifiers are compact, professional ste- reo power amplifiers engineered to meet the most de- manding sound reinforcement needs. They compare very favorably to more expensive amplifiers, providing uncolored sound and signal-to-noise ratios commonly associated with recording studios.

This manual will help you successfully install and use your amplifier—we strongly recommend you read all instructions, warnings and cautions. If you plan to oper- ate in one of the two mono modes, be sure to read Sec- tion 2.2. Also for your protection, please save your bill of sale as it is your official proof of purchase.

1.1 Unpacking

Please unpack and inspect your new amplifier for any damage that may have occurred during transit. If dam- age is found, notify the transportation company imme- diately. Only you, the consignee, may initiate a claim with the carrier for damage resulting during shipment. Even if the unit arrived in perfect condition, as most do, save all packing materials so you will have them if you ever need to transport the unit. NEVER SHIP THE

UNIT WITHOUT THE FACTORY PACK.

1.2 Features

Rugged, professional power amplifier built for the road. Mounts in a standard 19 inch (48.3 cm) rack.

Crown’s patented grounded bridge circuitry gener- ates large voltage swings while avoiding electrical stress on the output stages. This results in low distortion and high reliability.

Front panel power switch with turn-on delay for loud- speaker protection.

Patented Output Device Emulation Protection (ODEP®) keeps the amplifier working when others would fail.

High damping factor provides superior control over low frequency drivers for a clean, accurate low end.

Safe with any load. Bridge-Mono and Parallel-Mono modes offer optimal load-matching performance.

Complete protection against shorted outputs, mis- matched loads, overheating, DC input/output and high- frequency overload; full internal fault protection.

Balanced phone jack inputs with internal three-position sensitivity switch. Optional XLR or barrier block input connectors are available with the MT-XLRor MT-BBac- cessories.

Ground lift switch is provided to isolate the chassis ground from the phone jack input ground.

Efficient heat sinks and self-contained forced air cool- ing system dissipate heat quickly and evenly for extra amplifier protection and greater power output.

Three year “No-Fault” full warranty and guaranteed specifications protect your investment.
