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 […]
Hifisonix Speaker Protection PCB
in Power amplifiers
This PCB uses the Unisonic uPC1237 and provides DC offset protection and switch ON/OFF muting. Rather than use a relay to connect the loudspeaker to the amplifier, the Hifisonix Speaker Protection Board uses mosfets which do not suffer from arcing or any other wear out mechanisms. Additionally, there is a short circuit input provided that […]
Hifisonix Micro Ripple Eater (MRE) PCB
in Power amplifiers, Power supplies
The MRE can supply up to 10A from each power supply rail of up to +-50V with suitable heatsinking. It suppresses LF ripple by 40 dB and HF ripple by more than 50 dB and makes a perfect complement to any high performance DIY amplifier. It can be used with higher supply rails, provided the […]
