- • Not ideal for: Users needing wireless connectivity or high-power PA systems
Dual-channel Class-D amplification using a PAM8610 chipset delivers 10W per channel with around 90% efficiency. On-board protections and low THD+N keep operation reliable and quiet.
Quiet, efficient amplification, with PAM8610 Class-D chip
PAM8610 is a D-level stereo amplifier IC that drives two channels at up to 10W each while operating at roughly 90% efficiency. The class-D architecture minimises wasted energy and reduces power draw compared with linear designs.
High efficiency reduces heat and power requirements, making it easy to run from a modest DC 12V supply and suitable for compact or portable installations.
Low distortion playback, with THD+N 0.1% specification
Measured THD+N of 0.1% is achieved without extra filtering, reflecting careful PCB layout and the amplifier topology. Low static current also helps maintain a clean noise floor.
Clearer sound at moderate listening levels suits nearfield listening and small speaker systems, so vocals and instruments remain intelligible.
Safer operation and quieter background, with built-in protections and noise cancelling
On-board over-current, over-temperature and short-circuit protection guard against common electrical faults, while low EMI and a power-off noise-cancelling function reduce audible hiss.
Long-term reliability is easier to achieve and connected speakers face less risk from fault conditions, while background noise stays low during quiet passages.
