Audiophonics HPA-S300NIL

Power Amplifier Class D Stereo Nilai500DIY 2x300W 4 Ohm

Audiophonics HPA-S300NIL Power Amplifier Class D Stereo Nilai500DIY 2x300W 4 Ohm

Hand-assembled in our workshop in France, the Audiophonics HPA-S300NIL power amplifier is a high-performance stereo model, based on the new Hypex Nilai500DIY amplification solution. This delivers high power output with very low noise and distortion, for clear, precise sound reproduction. These modules are combined with a specially designed power supply, the Hypex PS500DIY, providing audio circuits with a clean, stable electrical signal. The whole unit is housed in a solid, sand-blasted aluminum case, revealing both a massive, modern design and perfect heat dissipation.

Dual Nilai500DIY modules

Each channel of the Audiophonics HPA-S300NIL features its own Class D Hypex Nilai500DIY amplifier module. These, integrated in a stereo architecture, ensure exceptional sonic performance, and enable the development of significant power, with no less than 300W per channel at 4Ω. Each module features high-end components, including a totally discrete buffer stage and high-quality voltage regulators, as well as a brand-new control loop technology. The result is a drastic reduction in distortion, noise and output impedance, enabling the HPA-S300NIL to reveal a rich, precise sound with a wide soundstage.

PS500DIY Power supply

The Nilai500DIY modules are combined with a specially designed Hypex PS500DIY switch mode power supply. This features audiophile-grade components and PFC (Power Factor Correction) to ensure high power density and a significant reduction in EMI interference conductivity. The module also incorporates a complete protection system for enhanced device durability.

Switchable RCA and XLR inputs

The HPA-S300NIL features dual input connectors with two RCA ports (dual mono single-ended) and two XLR ports (dual mono balanced). The RCA connectors are 24k gold-plated with heat-resistant plastic caps. The XLR connectors are from Neutrik, and feature a high-quality design with metal locking latch.

A two-position selector switch makes it easy to alternate between XLR and RCA inputs. So you can connect two different preamplifiers and alternate input sources.

High-quality speaker terminal blocks

The Audiophonics HPA-S300NIL features two pairs of 24-carat gold-plated speaker terminals on the rear panel. These terminals are designed to accept banana plugs up to Ø4mm in diameter. They can also accommodate bare conductors thanks to a Ø5.3mm screw-lockable slot.

5-12V Trigger

A double trigger socket (input and output) brings the convenience of an automated and particularly practical power sequence to your entire audio system. The power input is via an IEC C14 socket. This is fitted with a 5x20mm 6.3A fuse (supplied and pre-installed).

This amplifier's trigger needs to be used with a mono trigger cable (sold separately).

Effective heat dissipation

As a high-power amplifier, the HPA-S300NIL is, quite naturally, subject to thermal stress during use. Heat management is therefore of paramount importance, both to maintain amplification performance and to ensure excellent durability.

The chassis, entirely designed in sand-blasted aluminum, is equipped on its sides with two imposing radiators capable of efficiently dissipating heat. In addition, carefully distributed ventilation holes promote air circulation and heat dissipation. The heat sinks also contribute to the amplifier's solid, modern aesthetic.
