WARNING
TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT EXPOSE THIS EQUIPMENT TO RAIN OR MOISTURE!
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.
The lightning bolt triangle is used to alert the user to the risk of electric shock.
The exclamation point triangle is used to alert the user to important operating or maintenance instructions.

Fig. 1.1 1400 CSL Front and Back Panels
1 Welcome
Congratulations on your purchase of a Crown® CSL® 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 standard 19 inch (48.3 cm) equipment rack.
Front panel power switch with turn-on delay for loudspeaker 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 lowfrequency 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, mismatched loads, overheating, DC input/output and highfrequency overload; full internal fault protection.
Balanced phone jack inputs with internal three-posi- tion sensitivity switch. Optional XLR or barrier block input connectors are available with the MT-XLR and MT-BB accessories.
Ground lift switch helps prevent “ground loops” by isolating the chassis from the phone input grounds.
Efficient heat sinks and self-contained forced air cooling 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. This reduces the 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. IMPORTANT! Allow for adequate ventilation.

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 are avail-

able with the MT-XLR accessory. See Section 5.)
4.An appropriate AC cord and plug are provided. Use an isolated wall outlet with the correct voltage and adequate current. Voltages more than 10% over the amplifier’s rated voltage may damage the ±15 volt regu-
lator, filter capacitors and output transistors.
2.1 Stereo
1.Turn 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.
B R I D G E - M O N O
1.Turn 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.Turn 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.Turn 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.Turn 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-
