We're proud to present the Audiophonics AP300-M450ET, a Class D mono power amplifier based on a Purifi 1ET6525SA module. This ready-to-install and ready-to-use version is aimed at audiophiles who want a foolproof amplification solution, with considerable power reserve and impeccable linearity. The PURIFI 1ET6525SA is one of the most rigorous Class D amplification solutions on the market, with measured performance that is simply outstanding.
The result is a high level of sound reproduction, suitable for use with demanding speakers, large listening rooms or studio applications requiring considerable headroom without compromising on the precision and richness of the audio message.
All components are housed in a sober, robust and compact 100% aluminum case. It features openings to facilitate heat dissipation. Its design also limits the impact of interference on the signal.
The SMPS600N400 switched-mode power supply is an ultra-high-efficiency model capable of delivering 600 Watts of rated power in an extremely compact package. It has been specifically designed and developed by HYPEX to supply the 2 x 65V voltage required to operate the most demanding amplifier modules.
This high-quality, low-noise power supply meets the power requirements of the amplifier modules in every respect. What's more, the amplifier modules themselves have an excellent ability to reject power supply noise. As a result, the AP300-M450ET is extremely insensitive to mains imperfections and voltage/current variations that can cause parasitic noise.
The amplifier module is controlled by an interface board of our own design.
An Audiophonics OPA1656 OPA is used, a very low distortion OPA offering the highest transparency with very low THD. It is socket-mounted, allowing replacement if necessary.
To suit all uses, we have opted for 4 gain settings, selectable by jumper on the underside of the unit:
Designed for easy integration, the AP300-M450ET features both balanced (XLR) and single-ended (RCA) mono inputs. A bipolar selector switch makes it easy to change the input source.
At the output, BP-207 carbon / 24k gold insulated terminal blocks Ø5.5mm ensure an excellent connection with the loudspeakers.
The AP300-M450ET features a 5-12V trigger input integrated into a low-power circuit (5 mA). This means your amplifier blocks can easily join your Hi-Fi installations with remote-controlled switch-on.
