Exclusive Magna Hifi Upgrade: 12V Trigger Input for Singxer SA-90 Mono Power Amplifiers
At Magna Hifi, we’re big fans of the Singxer SA-90 mono power amplifiers — they're wonderfully built, sound fantastic, and look stunning in any setup. But one question kept coming back from our customers:
“Can I power on the SA-90 remotely via a 12V trigger?”
Until now, the answer was no. So we decided to do something about it.
We’re proud to offer a Magna Hifi-exclusive upgrade: a professionally integrated 12V trigger input (3.5mm jack) that allows your SA-90s to power on simultaneously and automatically via the 12V trigger output of your preamp, streamer, or other source device.
This trigger input works with any component featuring a 12V trigger output — including popular devices such as:
- Eversolo DMP-A6, DMP-A6 Master Edition, DMP-A6 Gen2, DMP-A8, DMP-A10
- Matrix Audio streamers and DACs
- And basically any audio device with a 12V trigger out
The modification is done securely and safely, with full respect for the original circuitry — and without voiding your warranty.
When you order a stereo pair, a short split cable is included to make setup simple. For more flexibility, you can select an optional 2 meter or 5 meter trigger cable at no extra cost. Need a custom length? No problem — just ask!
This upgrade brings true convenience to your high-end setup — just the way it should be.
