1.1 Unpacking

Please unpack and inspect your new amplifier for any

damage that may have occurred during transit. If

damage is found, notify the transportation company

immediately. Only you may initiate a claim with the

carrier for shipping damage. 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 EIA standard 19-inch (48.3-cm) rack.

❏ Quick-access front panel power switch and level

controls. Turn-on delay for loudspeaker protection.

❏ The patented

ODEP

circuitry and

Grounded Bridge

™

design combine to provide performance and reliability

that surpass all traditional designs.

❏ Easy to read signal presence (SPI) and distortion

(

IOC

) indicator for each channel.

❏ 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 make it easy to optimize the amplifier’s perfor-

mance for a wide range of loads.

❏ Complete protection against shorted outputs, mis-

matched loads, overheating, input/output DC and high-

frequency overload; full internal fault protection.

❏ Balanced phone jack inputs in parallel with XLR input

connectors. Barrier block input connectors are optional.

❏ Efficient heat sinks and self-contained forced-air

cooling system dissipate heat quickly and evenly for

extra amplifier protection and greater output power.

❏ The ONLY three-year, no-fault, fully transferrable

warranty.

1 Welcome

Congratulations on purchasing a Crown

Power-Tech

™

Series

amplifier. Power-Tech .1 Series amplifiers are

compact, professional stereo power amplifiers engi-

neered to meet the most demanding sound reinforce-

ment needs. They compare very favorably to more

expensive amplifiers, providing uncolored sound and

signal-to-noise ratios commonly associated with record-

ing 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

operate in one of the two mono modes, be sure to read

the Mono section. Also for your protection, please save

your bill of sale since it is your

official proof of pur-

chase.
