X-Altra MC/MM Phono EQ Amplifier
in Complete products, Preamplifiers, Vinyl preamps
Featured in a two-part article in the influential professional audio publication audioXpress (February and March 2021), this phono preamplifier offers the lowest noise of any MC amplifier available. At just 232 pico Volts per root Hertz, the noise performance is at the theoretical limit of what is possible for the given operating parameters. Typically, the […]
2 Off ax-Amplifier Module PCB
in Power amplifiers
2 off amplifier PCBs each measuring 344mm x 85mm for the 60W RMS ultra-low distortion class A amplifier as featured in audioXpress April and May 2024 (note, the production PCB’s are NOT gold plated – standard HASL finish)
Hifisonix Improved Soft Start + DC Blocker PCB aka iSSDCB
in Power amplifiers, Power supplies
The Improved SS + DCB aka iSSDCB provides mains in-rush current limiting to 10A and blocks any DC on the mains making this a welcome upgrade for any power amplifier. The maximum continuous AC mains load current that the board supports is 4.6A RMS. On 240VAC mains supply this translates to a continuous load of […]
