Ferrum Audio
Ferrum Audio is a result of a locally designed and manufactured audiophile grade audio electronics, which is the culmination of years worth of experience and knowledge. It is time to conquer the world. This is Ferrum’s heritage.
Ferrum Audio OOR
the only headphone amplifier with a soul
Truly Balanced
The signal path stays truly balanced using the XLR inputs and becomes truly balanced using the RCA inputs.
Ease of use
only three knobs on the front panel to control the most important settings.
Ferrum Power Link
OOR performs very, very good right out of the box. But OOR is made to excel above and beyond when used together with HYPSOS. Ferrum uses a Ferrum Power Link (FPL in short) to connect the two. HYPSOS then will perform to its maximum, unleashing unheard musicality from the combination with OOR.
Superior control
Perfected steering of output transistors protect them and never let them turn off, therefore reducing distortion to inaudible levels and keeping them in a state where they can instantly unleash all their power, crucial for high dynamics, superlative control and authority in sound.
Enhanced transparency
The whole design is focused on a balanced and very transparent sound signature, making listening fatigue something of the past.
Discrete design
The discrete power amp technology is developed in-house to achieve the best possible analog quality.
Ferrum Hypsos
hybrid power system
Hybrid Power System
Linear/switching hybrid design to get the advantages from both techniques—low ripple and noise as well as fast transient response and high efficiency.
Sweet Spot Tuning (SST)
Possibility to fine tune the output voltage for the best sound. The voltage level can be safely adjusted on the fly to allow easy comparison testing.
Advanced Automation
Compatibility with Apple TV remote, Trigger in/out connector; possibility to automate power-up of the devices with standby mode even without dedicated trigger connection.
Detailed and Revealing, Un-fatiguing Sound
Makes your current audio setup perform to its potential. Tweak the sound modifying the voltage level on the fly and use the preferred combination of the 4-Terminal Sensing and Spread Spectrum Mode settings.
Distinct User Levels
Using pre-configured settings from the list of supported devices or setting custom parameters manually. Wide continuous output voltage range of 5-30V with up to 6A of current delivered to the load. HYPSOS is as universal a device as it gets.
4T Sensing Design (4TSD)
Ensuring the exact voltage level precisely at the point of the powered device DC input terminal – special cable design and feedback to ensure flat voltage at every moment. This technique eliminates the harmful effects of the cable’s resistance effectively improving transient response.
Extremely Safe to Use
Automatic Transformer Voltage Adjust (ATVA), Electronic Output Voltage Polarity Switch and over-voltage, current limit and short protection. Settings lock to prevent accidental change of the parameters.
