HPA-NXL500 R4 Amplifier Module
The NXV500L is designed as a very high performance, high end audio amplifier in the Recording Studio's, Audiophile Amplifier's, Home Theatre and Sub-Woofer Amplifier's
The NXV500L R4 has XLR Balanced inputs as standard and it can be configured for RCA single ended input as well.
The latest NXL500 R4 version now has a multi-turn trimmer to adjust for minimum DC offset. Typically 1mv offset or less can be achieved.
The performance of this amplifier is truly awesome and unlike a lot of amplifiers these days. The power ratings are continuously rated sine wave into a resistive load.
The HPA-nxV500L amplifier module has a world wide fan base and it has been shown from extensive listening tests from around the world that this amplifier module rivals even the best sounding and most expensive amplifiers in the world regardless of price. Based on this the HPA-nxV500L represents extremely great value for money.
