Wiring a Crown power amplifier for standard operation is a simple affair, with clearly labeled connections and configurations printed on the back panel. As with any audio component, it is important to use high-quality cables and connectors of the correct type and size to avoid equipment damage. Crown Audio developed one of the first solid-state power amplifiers in the late 1960s with the DC 300, which soon became the music industry standard. Crown amplifiers are known for their reliability, world-class sound and ease of use.
Things You'll Need:
- 2 Speakers
- Audio Source
- 2 Unshielded Audio Speaker Cables
- 2 Shielded Audio Input Cables
Connect the Audio Device to the Amplifier
Determine the output connector type on your audio source by looking at the section labeled "output" on the back of the unit. Depending on the device, the connectors will be either RCA, XLR, 1/4 inch or bare wire terminals. When wiring for standard stereo operation, there will be one output for the left channel and one for the right channel.
Determine the amplifier's input connector type by looking at the section labeled "input" on the back of the unit. Depending on the amplifier model, the connectors will be either RCA, XLR, 1/4 inch or bare wire terminals. When wiring for standard stereo operation, there will be one input for the left channel and one for the right channel.
Connect one end of a shielded audio cable into the left channel output of the audio device and the other end into the left channel input of the amplifier. Repeat for the right channel of the device and amplifier.
Connect the Amplifier to the Speakers
Determine the output connector type of the amplifier by looking at the section labeled "output" on the back of the unit. Depending on the amplifier model, the connectors will be either RCA, XLR, 1/4 inch, bare wire terminals, banana plugs or Speakon connectors. When wiring for standard stereo operation, there will be one output for the left speaker and one for the right speaker.
Determine the input connector type of the speakers by looking at the input panel on the back of the units. Depending on the speaker model, the connectors will be either RCA, XLR, 1/4 inch, bare wire terminal, banana plug or Speakon connectors.
Connect one end of an unshielded audio cable into the left channel output of the amplifier and the other end into the input of the left speaker. Repeat for the right channel output into the remaining speaker.
Test for operation by turning on the power of the audio device and amplifier. Play recorded music or speak into a microphone while adjusting the volume controls on the amplifier and audio source until satisfactory volume level is reached. Check that both speakers are operational.
Tip
Only use shielded audio cable for wiring devices to the amplifier inputs, and unshielded speaker wire for output connections from the amplifier to the speaker.
Cables may be fitted with proper connectors if you have soldering skills, or they may be purchased or fabricated at your local music or audio supply retailer.
For non-standard stereo wiring using multiple speakers, or bridged-mono amplifier operation, consult the amplifier owner's manual or the Crown website for details. Non-standard wiring may be slightly different from model to model.
Some amplifiers provide a choice of more than one input and output connection. Consult the owner's manual or company website for details.
Warnings:
- Consult your owner's manual for the speakers and amplifier for power handling and ohm rating specifications. Speakers can be permanently damaged if they are not able to handle the amplifier's wattage output. The amplifier will be damaged if the ohm rating of the speakers is below the ohm rating of the amplifier. Always double-check your connections. Incorrect or loose wiring can cause damage to equipment.
