Application and Compatibility

Intended for compatible subwoofer projects used in event sound, DJ systems, venues and fixed installations. This model is dedicated to bass reinforcement and is not intended for midrange or high-frequency drivers. Have a qualified technician verify driver power handling, enclosure design, gain settings and final speaker impedance. Ratings are supplied for 4-ohm and 8-ohm loads; do not assume operation below 4 ohms is supported. A passive companion speaker changes the combined load and must be checked before connection.

Contents and Mounting

One integrated amplifier panel/module is described as included. The kit designation does not establish that a speaker driver, enclosure, mounting hardware or cables are included; confirm any required accessories before ordering.

The source recommends a recessed wooden mounting compartment rather than fixing the amplifier directly to an enclosure exposed to internal vibration. Have a qualified installer verify this arrangement, mounting cutout, vibration isolation and ventilation against the current manual. The listed panel dimensions are equipment measurements, not packed shipping dimensions. No measured shipping weight was supplied.

Electrical Safety and Care

• Professional installation is recommended. Check the equipment label for supply voltage, mains frequency, input current and grounding requirements.
• Automatic 110V/220V selection does not establish worldwide electrical compatibility. Have an electrician confirm circuit capacity, wiring and protective devices.
• Audio output power is not the same as mains power consumption.
• Disconnect mains power before wiring, mounting or servicing. Internal servicing should be performed by qualified personnel.
• Keep dry and maintain the ventilation clearances specified by the manufacturer.
• Reduce signal level when clipping is indicated and use hearing-safe listening levels. A limiter does not guarantee distortion-free operation or prevent every type of speaker or amplifier damage.

The previous listing mentions a manufacturer warranty as both 180 days and six months. Confirm the written duration, coverage and service arrangements for this item and destination before relying on those terms.
