HPA-NXL200 R5.3 Power Amplifier Module
The new R5.3 Amplifier Module!
Decoupling caps increased from 150uf to 390uf and more!
The NXL200 R5.3 is a brand new high performance audio power amplifier module, delivering world class high end sound quality from a very compact all SMT component design.
Featuring very high precision low noise current sources, no input/output capacitors anywhere in the signal path including the feedback, it has a high precision low noise DC servo circuitry to correct DC offset to lower than 1mv, even any DC presented on the input will be corrected.
The design also features very low SNR at -110db with respect to full power output.
Multiple channels can be added onto a common heat sink for home theatre amplifiers.
All this with a footprint no larger than 70mm x 60mm.
