Introduction to the HPA-nxV203PS
The HPA-nxV203PS is the next generation in the nxV20xPS series of amplifiers. Based on the very popular HPA-nxV200, the HPA-nxv203ps is designed to meet the needs of people who want to have an easier solution to building their own multi channel high end audio amplifier, for applications based around active or DSP based loudspeakers or multi channel home theatre amplifiers.
What we have done with the HPA-nxV203ps is to combine three upgraded nxV200 amplifier modules and a high performance low noise linear power supply. In a very compact form factor measuring only 275mm x 73 x 45mm.
The power supply section of the nxV203ps has two high current Shottky diode full wave rectifiers and comes standard with four 10,000uf 63 volt high quality filter capacitors on board, making a total filter bank of 40,000uf on board. As much as 15,000uf 63 volt capacitors can be supplied if so desired.
One of the more notable features of the nxV203ps module is the ability of the module to bridge channel one and channel two with no more than a single jumper. This makes channel One and channel Two into a single high power 310 watt amplifier, while still having the addition of another 110 watt @ 8ohm amplifier, available.
So in essence converting the module into a two channel module, with the added advantage of at least 3 times the power output into 8 ohms, for channel One-Two and up to 180 watts into 4 ohms for channel Three.
To get the HPA-nxV201PS amplifier module up and running, all that is required is a 625VA transformer with 2 x 35vac secondary windings and a suitable heat sink such as the Conrad MF30-75 for each three channel module.
The 625VA power transfomers to suit the HPA-nxV203ps are available from Holton Precision Audio or they can be purchased from Harbuch Electronics. A link for Harbuch Electronics can be found in the Links page of this web site.
The amplifier module is also supplied with audiophile grade Nichicon KZ MUSE supply de-couplers and Nichicon MUSE ES BP capacitors for the feedback circuit as standard.
Shown below is some application examples for the HPA-nxV203ps amplifier module, it is by no means an exhaustive list of applications, but it does demonstrate the flexibility of this awesome amplifier module.
The HPA-nxV203ps can be supplied mounted on a Conrad MF30-75 heat sink as shown in the photos below. Please contact us via email or phone for further details and costs.
