Ferrum HYPSOS Dual-Output Smart Universal Power Supply System at Vinyl Sound Buffalo, New York

The Ferrum HYPSOS Dual Output is an advanced hybrid power supply system from Ferrum Audio (Warsaw, Poland), available at Vinyl Sound in Buffalo, New York. It extends the award-winning HYPSOS Single Output platform by providing two simultaneous DC outputs sharing a common voltage, allowing a single unit to power both the WANDLA DAC and the OOR headphone amplifier, or any two compatible devices, via a single mains connection. Both outputs share the same 5 to 30 V DC continuously adjustable voltage range, with 60 W and 6 A combined continuous output across both channels. The 4T Sensing Design (4TSD) is active on the main output via the proprietary Ferrum Power Link connector, delivering real-time voltage sensing at the load rather than at the supply terminal. The HYPSOS won the EISA Best Product 2021-2022 Award in its Single Output form; the Dual Output extends its capability for multi-component Ferrum and third-party audio systems.

Dual Output Architecture and Shared Voltage Design

The HYPSOS Dual Output provides two independent DC output terminals that share a single regulated voltage. The same voltage level is applied to both outputs simultaneously, meaning both connected devices must be compatible with the selected operating voltage. Combined continuous output current across both outputs is 6 A and combined maximum continuous output power is 60 W. The 4T Sensing Design is active only on the main output via the FPL cable connection, providing the full sensing-corrected voltage regulation for the primary Ferrum component such as the OOR or WANDLA. The secondary output delivers regulated voltage without FPL sensing, operating as a conventional high-quality regulated DC supply for the second connected device. Sweet Spot Tuning voltage adjustment applies to both outputs simultaneously.

Hybrid Linear-Switching Topology and 4T Sensing Design

The HYPSOS combines a linear power supply topology with a switching supply in a single chassis to capture the advantages of each approach. The linear section provides the low ripple, low noise, and absence of switching interference associated with transformer-based designs, while the switching section contributes fast transient response and high efficiency. The two-stage EMI filter on the IEC C14 mains inlet provides additional rejection of mains-borne noise before the power conversion stage. The 4T Sensing Design uses a four-conductor Ferrum Power Link cable to route a dedicated sensing wire directly to the load's internal power rail, allowing the HYPSOS to measure voltage at the point of consumption and continuously correct delivery in real time. This eliminates the effect of DC cable resistance that standard two-wire power delivery cannot compensate for, resulting in flat voltage at the load under all dynamic current demand conditions.

Frequently Asked Questions

What is the Ferrum HYPSOS Dual Output?

The Ferrum HYPSOS Dual Output is a hybrid linear-switching power supply system from Ferrum Audio in Warsaw, Poland, providing two simultaneous DC output channels sharing a single continuously adjustable voltage from 5 to 30 V, with 60 W and 6 A combined continuous output. It is built on the platform of the EISA Best Product 2021-2022 HYPSOS Single Output and adds a second output channel for powering two audio components simultaneously. It is available at Vinyl Sound in Buffalo, New York.

How does the HYPSOS Dual Output differ from the HYPSOS Single Output?

The HYPSOS Dual Output provides two independent DC output terminals operating at the same voltage simultaneously, compared to the Single Output's single DC terminal. Both outputs share the same 5 to 30 V adjustable voltage, meaning both connected devices must accept the same operating voltage. Combined output capacity is 60 W and 6 A across both channels, compared to the Single Output's 80 W and 6 A. The 4T Sensing Design via FPL cable is active only on the Dual Output's main output terminal, not on the secondary output. The Dual Output is ideal for simultaneously powering the OOR and WANDLA from a single unit, reducing the number of power supplies required in a full Ferrum stack.

Can both outputs of the HYPSOS Dual Output use the Ferrum Power Link cable?

No. The 4T Sensing Design is only active on the main output terminal of the HYPSOS Dual Output, which connects via the proprietary Ferrum Power Link FPL cable to one Ferrum component such as the OOR or WANDLA. The secondary output terminal provides regulated DC via a standard 5.5 mm barrel connector without FPL sensing. The secondary output is still a high-quality regulated supply that benefits from the HYPSOS's hybrid linear-switching topology, but voltage is regulated at the supply output rather than at the load's internal rail. Users seeking FPL sensing on both components will require two HYPSOS Single Output units.

What third-party audio components are compatible with the HYPSOS?

The HYPSOS is designed as a universal audiophile power supply with a 5 to 30 V continuously adjustable range, covering a broad range of DC-powered audio components beyond the Ferrum family. Compatible categories include network streamers, DACs, headphone amplifiers, phono preamplifiers, and network switches from numerous manufacturers. Ferrum maintains a compatibility list on their website. When using the HYPSOS with third-party devices via the standard 5.5 mm barrel connector, the 4T Sensing Design is not active, but the hybrid linear-switching topology, Sweet Spot Tuning, and Advanced Automation features remain fully functional. The adjustable voltage range and on-the-fly SST tuning allow optimisation of operating voltage for each connected third-party device.

What is Sweet Spot Tuning and how is it used?

Sweet Spot Tuning is the HYPSOS's ability to adjust its output voltage on the fly during playback in fine increments across the full 5 to 30 V range. For Ferrum components, the recommended operating range is typically 22 to 30 V. SST allows the user to step through voltage levels while music plays and identify the specific voltage at which the connected device sounds subjectively best or measures lowest noise. For the OOR and WANDLA, the typical operating voltage is 24 V but adjusting to 25 or 26 V may yield audible differences depending on the specific unit. Sweet Spot Tuning is also useful for third-party components where the manufacturer's nominal voltage may not represent the optimal operating point.

Does the HYPSOS Dual Output include cables in the box?

The HYPSOS Dual Output ships with a high-quality DC power cable fitted to the most commonly used DC input connector. Custom cables for alternative connector sizes or lengths are available to order. The Ferrum Power Link FPL cable for 4T Sensing connection to OOR, WANDLA, or ERCO Gen 2 is a separate purchase. A Ferrum Power Splitter accessory is also available separately from Vinyl Sound Buffalo for use with HYPSOS Single Output units that require a second output using the legacy splitter approach.
