Ferrum Audio DC JACK powering cord 2.5
Overview
Ferrum’s HYPSOS power supply was designed to transcend the boundaries of its home ecosystem. This DC Jack 2.5 cable is precisely what builds the bridge to third‑party devices: equipped with a proprietary 4‑pin connector on one end and a 5.5 × 2.5 mm DC jack plug on the other, it allows HYPSOS to be connected to any audio device fitted with this very widespread power input standard used in the industry.
A universal connector to expand HYPSOS’s capabilities
The 5.5 × 2.5 mm format is one of the two most common standards for DC power on audio devices. It is found on many DACs, phono preamplifiers, audiophile network switches, and motorized turntables. The DC Jack Powering Cord 2.5 provides the appropriate termination for this compatibility, while its 2.1 version covers the other widely used standard.
On the HYPSOS side, the cable uses Ferrum’s proprietary 4‑pin connector, ensuring a stable and reliable connection with the power supply unit. Gold‑plated contacts provide optimal conductivity and long‑term resistance to oxidation.
Taking advantage of Ferrum’s hybrid power supply
The value of this cable lies in what it gives access to: HYPSOS’s hybrid power technology, which combines the benefits of linear and switching power supplies. HYPSOS delivers an adjustable DC voltage from 5 to 30 V with a current of up to 6 A, all with low residual noise and fast transient response.
Thanks to HYPSOS’s software interface, the output voltage and polarity can be set according to the needs of the powered device. Ferrum also maintains a compatibility list integrated into the firmware, with presets for many products on the market. For devices not listed, a manual mode allows you to define the appropriate parameters.
How this cable differs from the Ferrum Power Link
This cable should be distinguished from the Ferrum Power Link (FPL), which is reserved for Ferrum products such as the OOR, ERCO, or WANDLA. The FPL uses four conductors: two for power, two for the sensing return, allowing HYPSOS to correct voltage variations in real time directly at the device. This 4T Sensing technology is not available with the standard DC Jack, which is limited to a conventional two‑conductor power transfer.
The DC Jack Powering Cord 2.5 nevertheless remains the only way to use HYPSOS with third‑party equipment that does not feature the proprietary FPL connector.

Frequently Asked Questions
How do I know whether my device uses a 2.5 mm or 2.1 mm connector?
This information is generally indicated on the original power supply or in the manufacturer’s technical documentation. If in doubt, a caliper can be used to measure the internal diameter of the socket. The 2.5 mm is slightly wider than the 2.1 mm, and the two are not interchangeable.
Can this cable be used with Ferrum products such as the OOR or WANDLA?
Technically yes, since these devices also have a 5.5 × 2.5 mm DC input in addition to the FPL connector. However, the Ferrum Power Link cable remains recommended for these products because it uses 4T Sensing technology, providing more precise voltage regulation and better performance.
Is HYPSOS supplied with this cable?
HYPSOS comes with two DC Jack cables: a 2.5 mm version and a 2.1 mm version. This cable can therefore be purchased separately if a different length is needed or to replace a damaged cable.
What is the polarity of the DC jack connector?
The connector is configured as center‑positive, the most common configuration in the audio industry. However, HYPSOS’s output polarity can be electronically inverted if the powered device requires a center‑negative configuration.
Are there any power limitations with this cable compared to the FPL?
No, the power capabilities remain identical. HYPSOS can deliver up to 80 W continuously through this cable. The difference from the FPL concerns only real‑time voltage regulation, not the power transmitted.
Is this cable suitable for powering an audiophile network switch?
Yes, provided that the switch accepts DC power via a 5.5 × 2.5 mm socket and that its voltage and current requirements fall within HYPSOS’s operating range. Several network switches are listed in Ferrum’s compatibility list.
