The Ultimate Guide to Soft Start Design - Neurochrome Audio
https://neurochrome.com/pages/the-ultimate-guide-to-soft-start-design
The toroidal power transformers in audio amplifiers draw large currents on start-up, which reduces their lifespan. This guide presents how to design and make a soft start using inrush limiters. I explore the limitations of power resistors, NTCs, …
Soft-Start Circuit For Power Amps
https://sound-au.com/project39.htm
Description. Although the soft start circuit can be added to any sized transformer, the winding resistance of 300VA and smaller transformers is generally sufficient to prevent a massive surge current. Use of a soft start circuit is definitely recommended for 500VA and larger transformers.

Soft Start Module SSM2 Mains Soft Start Module The common use of toroidal mains transformers in audio equipment has solved a great many problems but in doing so, has created others. One such problem is because the toroid uses a much smaller magnetic core, the high inrush current at power up is liable to blow any mains fuse fitted.

Soft-Start Power Supply for Amplifier Loudspeakers. Last Updated on September 17, 2020 by Swagatam 5 Comments. The proposed slow-start power supply circuit is specially designed for power amplifiers to ensure that the loudspeaker connected with the amplifier do not generate the loud and unwanted "thump" sound during power switch ON. This also implies that …
Soft start 220V - Kit-Amp

Soft start module for UMZCH power supply. Built according to a widespread and well-established scheme. This module is connected directly to the 220V network before the primary winding of the transformer of the audio frequency power amplifier. When the amplifier is turned on, the capacities in the power supply are discharged.
