Clean only with a dry cloth. Do not block any ventilation openings. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus including amplifiers that produce heat. Do not defeat the safety purpose of the polarized or grounding-type plug.
A polarized plug has two blades with one wider than the other. A grounding-type plug has two blades and a third grounding prong. The wide blade or the third prong is provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. Protect the power cord from being walked on or pinched, particularly at plugs, convenience receptacles, and the point where they exit from the apparatus.
Use only with a cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. Unplug this apparatus during lightning storms or when unused for long periods of time.
Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as powersupply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped. 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 exclamation point triangle is used to alert the user to important operating or maintenance instructions. Operation is subject to the following two conditions: 1 This device may not cause harmful interference, and 2 this device must accept any interference received, including interference that may cause undesired operation.
These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications.

Use a standard inch You may also stack amps without using a cabinet, or you may place a single amp on a surface with 12 inches of air space above the unit for convection cooling.
NOTE: When transporting in a rack, amps should be supported at the front and back. Figure 2. Allow 2U between units for convection cooling. The side walls of the rack should be a minimum of two inches 5. You should use 3-pin Phoenix-type cable ends at the amplifier inputs. Unbalanced line may also be used but may result in noise over long cable runs.
The RCA input connectors can also be used for unbalanced inputs. You may use crimpon spade lugs for your output connectors Figure 2. To prevent the possibility of short-circuits, wrap or otherwise insulate exposed loudspeaker cable connectors. Cover the output connections with the supplied non-touch cover. The wire sizes apply to the 4-ohm tap. Distance up to 25 ft. Wire Size 16 AWG ft. NOTE: Custom wiring should only be performed by qualified personnel. Class 2 wiring is required.
Top: Balanced. Bottom: Unbalanced. Use 2-conductor shielded cable and 3-pin Phoenix-type connectors for Line Output wiring Figure 2. Ceiling Speakers For each amplifier channel, connect the Amplifier Output screw terminals to the loudspeaker loads. NOTE: Crown provides a reference of wiring pin assignments for commonly used connector types in the Crown Amplifier Application Guide available at www. Turn off any equipment connected to the Line Out connectors.
