02PERFORMANCE

Stereo power with a dedicated subwoofer drive

The board handles a 2.0 channel configuration, pushing 50 watts to each side for balanced stereo imaging. A separate 100-watt output manages the subwoofer, adding depth and body to the low end without muddying the mid-range frequencies.

04PROTECTION

Built-in safeguards for reliable long-term operation

Internal circuitry monitors conditions to protect the board from common electrical mishaps. Guards against over-voltage, under-voltage, over-temperature, short circuits and reverse connection help maintain stability during extended listening sessions or variable power scenarios.

05SPECS

Compact dimensions within a lightweight carton

The packing carton measures 16 by 14 by 5 centimetres and weighs 0.28 kilograms. The small footprint makes it easy to store in a parts drawer or integrate into tight cabinet spaces where space is at a premium.
