The original Ferrum HYPSOS changed the external power supply landscape forever — combining the best of linear and switching technology into one category-defining product. Now, HYPSOS gets a sibling. The HYPSOS Dual Output takes everything that made the original extraordinary and doubles it, allowing you to power two devices simultaneously from a single unit, without compromise and without cable chaos.

If you've ever wanted to pair your OOR and WANDLA — or any two Ferrum devices with matching voltage requirements — under a single, reference-quality power supply, HYPSOS Dual Output is exactly what you've been waiting for.

Why Dual Output?

HYPSOS has always featured enormous power reserves — far more than a single device typically demands. Rather than let that headroom go to waste, Ferrum engineered HYPSOS Dual Output to put those reserves to work. Both outputs share the same voltage and draw from a combined current pool, meaning two devices can be powered simultaneously with the same precision, stability, and sonic benefit that single-device HYPSOS users have enjoyed since day one.

Key Features

Hybrid power system
A linear/switching hybrid design captures the advantages of both technologies — low ripple and noise from linear regulation, combined with fast transient response and high efficiency from switching technology. Now powering two devices at once.

Sweet Spot Tuning (SST)
Fine-tune the output voltage on the fly to find the optimal operating point for your connected devices. Safely adjust voltage levels during playback for easy A/B comparison — a feature unique to Ferrum.

4T Sensing Design (4TSD)
Ensures the exact voltage level at the DC input terminal of the powered device, not just at the supply output. The special cable design and feedback loop eliminate the harmful effects of cable resistance, effectively improving transient response. Active on the main output.

Easy setup
Choose from pre-configured settings for supported Ferrum devices or set custom parameters manually. A wide continuous output voltage range of 5–30V with up to 6A of combined current makes HYPSOS Dual Output one of the most versatile external power supplies available.

Advanced automation
Compatible with Apple TV remote, and features a Trigger in/out connector for automated power-up of connected devices — even without a dedicated trigger connection via standby mode.

Extremely safe to use
Automatic Transformer Voltage Adjust (ATVA), electronic output voltage polarity switch, and full overvoltage, current limit, and short circuit protection.

Included DC cable
Comes with a high-quality DC power cable fitted to order for the most commonly used DC inputs. Custom cables available to order.

About Ferrum

Designed and engineered by Ferrum / HEM in Warsaw, Poland. Ferrum was founded in early 2020 with a clear mandate: combine sustainability, durability, and quality into compact, attractive packages — focused entirely on delivering the best possible audio experience at an affordable price. The original HYPSOS redefined what a power supply could be. HYPSOS Dual Output carries that vision further still, proving that Ferrum's journey to change the landscape of high-end audio is very much a continuing saga.
