Magnetic Field

CAUTION! Do not locate sensitive high-gain equip­ment such as preamplifiers or tape decks directly
above or below the unit. Because this amplifier has

a high power density, it has a strong magnetic field
which can induce hum into unshielded devices that
are located nearby. The field is strongest just above
and below the unit.

If an equipment rack is used, we recommend locat­ing the amplifier(s) in the bottom of the rack and the
preamplifier or other sensitive equipment at the top.

alert the user to the

1 Welcome

Congratulations on your purchase of a Crown®
amplifier.

CSL

amplifiers are compact, professional ste­reo power amplifiers engineered to meet the most de­manding sound reinforcement needs. They compare
very favorably to more expensive amplifiers, providing
uncolored sound and signal-to-noise ratios 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 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 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 dam­age is found, notify the transportation company imme­diately . Only you 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 mounts in a stan-

dard 19 inch (48.3 cm) equipment rack.

❏ Front panel power switch with tur n-on delay for loud-

speaker protection.

❏ Full, uncolored power with any reasonable load.
❏ Patented Output Device Emulation Protection (

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 shor ted outputs, mis-

matched loads, overheating, DC input/output and high­frequency overload; full internal fault protection.

❏ Balanced phone jack inputs with inter nal three-posi-

tion sensitivity switch. Optional XLR or barrier block
input connectors are available with the

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.

2 Installation

Always remove power from the unit and turn the level
controls off when making connections

chance of loudspeaker damage from loud blasts.
Follow the guidelines listed next as well as the steps

required for the specific mode of operation:

1. Install the amplifier in a standard 19 inch (48.3 cm) rack
or place it on a stable surface. The mounting dimensions
are 19 inches (48.3 cm) wide, 3.5 inches (8.9 cm) tall
and 16 inches (40.6 cm) deep behind the mounting sur­face. IMPORT ANT! Allow for adequate ventilation.

2.1 Stereo

1. T urn the level controls down (fully counterclockwise) and
turn off the amplifier .

2. Set the back panel stereo/mono switch to Stereo.

3. If present, remove the Parallel-Mono jumper.

4. Connect the input and output cables as shown in the

first

example in Figure 2.3.

5. Turn on the amplifier and adjust the level for each chan­nel with the back panel level controls.

CAUTION: In Stereo mode, never parallel the two
outputs by directly tying them together, and never
parallel them with the output of another amplifier.

2.2 Mono

The monaural operating modes provide twice the
power to one channel as the Stereo mode. In Bridge­Mono mode, the outputs are wired in series for twice
the output voltage. In Parallel-Mono mode, the outputs
are paralleled for twice the current capacity.

Bridge-Mono mode is provided for loads with an im­pedance greater than 4 ohms. Parallel-Mono mode
should be used with loads of 4 ohms or less.

AIR FLOW

2. Use high-quality loudspeaker cables to connect the load
to the amplifier’s output jacks. Do not use shielded
cable. Banana plugs are recommended for this connec­tion.

3. Use shielded cables to connect audio sources to the
amplifier inputs. Either balanced or unbalanced wiring
can be used as shown below. (XLR connectors ar e avail-

1. T urn the level controls down (fully counterclockwise) and
turn off the amplifier .

2. Set the back panel stereo/mono switch to Bridge-Mono.

3. If present, remove the Parallel-Mono jumper.

4. Connect the input and output cables as shown in the
second example in Figure 2.3. Use the Ch.1 input only.

5. Make sure the load is balanced (neither side shorted to
ground) and

do not use the black (–) banana jacks.

6. Tur n on the amplifier and adjust the level. Use the Ch.1

level control

only.

P A R A L L E L - M O N O

1. T urn down the level controls (fully counterclockwise) and
turn off the amplifier .

2. Set the back panel stereo/mono switch to Parallel-Mono.

3. Install a solid jumper (at least 14 gauge) across the out­put between the two red (+) banana jacks.

4. Connect the input and output cables as shown in the
third example in Figure 2.3. Use the Ch.1 input only.

5. Tur n on the amplifier and adjust the level. Use the Ch.1

level control

only.

CAUTION: When wired for Parallel-Mono mode, do
not attempt to operate the amplifier in Stereo or
Bridge-Mono mode until the output jumper is re­moved. Failure to do so will result in inefficient op-
