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.

eration, distortion and excessive heating. 2.3 Input Sensitivity Adjustment The input sensitivity switch inside the amplifier is set to 0.775 volts at the factory. It can be changed to 1.4 volts or a voltage gain of 26 dB as follows: 1. -
Page 9: Operation
Crown invented ODEP to prevent amplifier shutdown during demanding operation and to increase the effi- ciency of the output circuitry. To do this, Crown estab- lished a rigorous program to measure the safe operating area (SOA) of each output transistor. Then, Crown designed intelligent circuitry to simulate instan- taneous transistor conditions. -
Page 10: Fuses And Circuit Breakers
This protection circuitry is activated in unusual situa- tions where the unit’s transformer temperature rises to unsafe levels. Under these abnormal conditions, the unit removes power to the high voltage transformer (the fan will also run in 120 VAC, 60 Hz units). The amplifier will return to normal after it cools to a safe temperature. -
Page 11: Specifications
CSL Series Power Amplifiers 4 Specifications The following applies to units in Stereo mode with 8 ohm loads and an input sensitivity of 26 dB unless otherwise specified. Standard 1 kHz Power: refers to maximum average power in watts at 1 kHz with 0.1% THD. Full Bandwidth Power: refers to maximum average power in watts from 20 Hz to 20 kHz with 0.1% THD. - Page 12 (Refer to Section 3.3.) Turn On: No dangerous transients. The four second (approximate) turn-on delay can be changed. Contact Crown’s Technical Support Group for details. Construction Durable black finish on steel chassis with special “flow- through”...
- Page 13 0.1% THD appears to be the industry standard. Two of the maximum average power ratings in each minimum power matrix are measured at 0.1% THD plus noise so you can easily compare Crown specifications to those of other manufacturers.
