The Audiophonics HPA-H250NC is a 6-channel Class D power amplifier based on three Hypex NCore NC252MP modules. This version is aimed in particular at audiophiles and home theater perfectionists who want to equip themselves with a foolproof amplification solution, with a good power reserve and impeccable linearity. The 6 channels of this amplifier can, for example, be used to integrate a high-performance 5.1 home theater system. What's more, the NCore modules offer exceptional performance for sound reproduction of breathtaking accuracy and dynamics.
All modules and components are housed in a sober, modern and robust 100% aluminum case, with openings and radiators to promote heat dissipation. Its design also limits the impact of interference on the signal.
The amplifier stage of the Audiophonics HPA-H250NC uses three Hypex NCore NC252MP modules. These Class D amplifiers offer excellent sonic performance and versatility. They deliver a very comfortable 6x250W at 4 Ohm or 6x150W at 8 Ohm, while benefiting from the high efficiency of this type of architecture.
The main features of these modules are their flat frequency response whatever the load impedance, their almost frequency-independent distortion level, and their ability to reject EMI interference. Their operation is based on a self-oscillating loop controlled by phase shifting, taking into account feedback only at the speaker output.
NCore amplifiers are the first Class D amplifiers not only to approach the performance of operational amplifiers, but also to surpass them in terms of sound reproduction quality. They deliver clear, rich, musical sound in a compact package. This NCore technology combines the stability of Hypex UcD amplifiers with lower distortion and output impedance.
NC252MP modules also incorporate the power supply stage. This consists of a regulated half-bridge switched-mode power supply (SMPS) with synchronous rectification on the main output rails. Compact, powerful and efficient, this power supply is particularly well suited to cleanly powering a Class D amplifier.
What's more, to offer complete compatibility with the voltages delivered by different electrical networks, the power supply is equipped with an automatic input voltage doubler. The NC252MP module also features an overload protection system.
With its 6 channels, the HPA-H250NC amplifier provides 6 XLR inputs. Outputs are simply made via speaker terminals, which accept stripped cables, banana plugs or forks. Two 5-12V trigger connectors in 3.5mm jack format enable the amplifier's automatic switch-on to be controlled when integrated into a compatible system.
