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 may initiate a claim with the carrier for
damage resulting during shipment. Even if the unit ar-
rived 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 Welcome
Congratulations on your purchase of a Crown ® 1400
CSL ® amplifier. The 1400 CSL amplifier is a compact,
professional stereo power amplifier engineered to meet
the most demanding sound reinforcement needs. It
compares very favorably to more expensive amplifiers,
providing uncolored sound and a signal-to-noise ratio
more 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 op-
erate in one of the two mono modes, be sure to read
the Mono section. Also for your protection, please save
your bill of sale as it is your official proof of purchase.
1.2 Features
❏ Rugged, professional power amplifier mounts in a stan-
dard 19-inch (48.3-cm) equipment rack.
❏ Front panel power switch with turn-on delay for loud-
speaker protection.
❏ Full, uncolored power with any reasonable load.
❏ 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-posi-
tion sensitivity switch. Optional XLR or barrier block in-
put connectors are available with the
MT-XLR and MT-
BB accessories.
❏ Ground lift switch helps prevent “ground loops” by iso-
lating the chassis from the phone input grounds.
❏ 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.
