Nilai500 Class D Amp Board
Nilai® Class D technology is here!Whether you are a serious audiophile or a DIY builder aiming to create your own high-performance amplifier, the Nilai500 amplifier module is an outstanding option. It brings together substantial power, excellent efficiency, and refined sound quality in a compact form that is simple to integrate into a custom design.
This major leap in performance brings distortion levels down by a factor of 10, improves power supply noise rejection by 10 times, and lowers output impedance by the same margin. Those numbers are impressive on their own, but their real impact becomes clear the moment you hear the results through your speakers.
The Nilai500 makes a strong impression with its high-output capability, delivering up to 500W at 2 ohms, 525W at 4 ohms, and 260W at 8 ohms. With a maximum output current of 25A and a ±70V voltage swing, it handles dynamic peaks with ease while producing a spacious soundstage and deep, well-controlled bass.
Built on NILAI® technology, the Nilai500 offers exceptional sound quality with very low distortion and a high signal-to-noise ratio, allowing music to be reproduced with impressive clarity and detail. Its efficient Class D design reaches better than 93% efficiency while preserving high-level audio performance and keeping heat generation and power consumption low. At idle, the power stage typically draws only 2.25W, making it a smart choice for high-performance systems that also value energy efficiency.
Designed with great attention to detail, the Nilai500 amplifier module uses carefully chosen high-quality components throughout to support the best possible audio performance. Every part is selected to reduce distortion, improve efficiency, and deliver outstanding sonic clarity, making it a compelling choice for listeners who expect more from their equipment. Its polished exterior also gives a fitting visual hint at the level of engineering inside.
Pairing the Nilai500 with the matching creates one of the most complete and ready-to-build DIY solutions available.

PreamplifiersA preamplifier boosts low-level signals up to line level, which is the standard operating level required by your power amplifier. That means a preamp is needed for nearly any audio source. In addition to raising low-level signals, a preamplifier also manages source switching and volume control for line-level inputs.

Mono power amps are often regarded as one of the best ways to build a high-quality amplifier system. They are commonly used in Hi-Fi and high-end audio systems, but they can also serve in musical instrument amplifier applications.

Stereo / Dual Power Amplifier A dual power amplifier contains two power supplies and two amplifier channels, with each channel running from its own dedicated power supply. Both the power supplies and amplifier sections are housed within a single enclosure. A stereo power amplifier uses one power supply to run two amplifier channels within the same enclosure.

Common multichannel designs include 4, 8, 16, or even 24 channels. Most use a single power supply, though some models may include two or more power supplies depending on the number of channels and the power demands.
