Aurium Headphone Amplifier
Output impedance adjustment provides a seamless interface with any type of headset.
Audiophile-quality headphones, something thought to belong in the ’70s, are back. Music enthusiasts have improved their listening experience by getting rid of earbuds and preferring high-fidelity headphones.
Aurium is Pathos’ answer to this new need: our best quality and technology in just a few cubic centimeters.
Aurium is a tube amplifier specifically designed for headphones. Work in pure Class A with zero-feedback.
It consists of:
- one INPUT stage with TAPE OUT to bypass the volume control
- a valve pre-stage in differential configuration
- a volume adjustment stage and a digital controller.
- a MOSFET output stage
- an auto-bias circuit that maintains a constant MOSFET operating point.
Volume
Volume control, a critical component in any amplifier, is handled by a high-precision Burr-Brown device.
A high-class ALPS potentiometer controls the digital volume stage, without interfering with the audio signal.
Aurium has two “bypass” outputs called TAPE OUT, one XLR and one RCA, which replicate the same signal as the selected input.
Even when Aurium is switched off, the input selector switches remain in operation. The signal is bypassed to the TAPE OUT and it is as if it came directly from the source.
Using the knob on the rear panel you can select the output gain in the headphones. This gives you the perfect flexibility to use the volume knob on the front panel, avoiding excessive volume.
The body of Aurium is obtained by hollowing out a block of solid aluminum, which is then painted.
Aurium is available in different color combinations, to match your system or to best express your personality.
