Installation and Speaker Matching

Installation and electrical connections should be performed by a qualified technician using the current manufacturer's manual. The source suggests one 4-ohm speaker rated up to 1200W or two 8-ohm speakers rated up to 600W each; these suggestions are not universal compatibility guarantees. The installer must verify wiring, final load, driver ratings and suitable limiter settings. This is not a full-range amplifier or a car-audio DC-power module unless the manufacturer expressly specifies otherwise.

Electrical Safety and Care

• Verify the supply voltage and frequency against the equipment label. Automatic dual voltage does not mean compatibility with every electrical installation or worldwide outlet.
• Have an electrician verify circuit capacity, wiring, sockets, grounding and protective devices. Audio output power is not the same as mains power consumption.
• Avoid extension leads; if necessary, have a qualified electrician select a suitably rated lead for the current and cable length.
• Disconnect mains power before installation, wiring or servicing. Do not touch internal circuitry; refer servicing to qualified personnel.
• Keep dry, maintain the ventilation clearances required by the manual and do not block cooling openings.
• Use hearing-safe listening levels. A limiter or clip indicator does not guarantee damage-free or distortion-free operation.
