The Auris Phonio is a phono stage that will give a unique warmth to your vinyl sound. It is designed to accept very low and very high output phono cartridge signal levels because it has adjustable gains between 43.2 dB and 69 dB. Phonio also provides the correct RIAA equalization in order to obtain a flat frequency response. Phonio uses two separate circuits dedicated to both moving coil and moving magnet cartridges and avoid compromises.
- Perfect RIAA curve
- Advanced topology
- Superb dynamics
- High-performance switchable MC & MM stage
- Linear Power Supply
Technology
Auris Phonio incorporates innovative design and thus Phonio has two entirely separate high-performance phono stages. Each stage has its own separate input sockets and input pre-amplifier circuit. This will allow you to use any cartridge without compromise.
Phonio is a specially designed ultra-low noise THD Phono Pre Amplifier with the best components. Low-noise MELF resistors were used as well as WIMA capacitors, with the combination of which we came to the desired and perfect RIAA curve.
Sound Plus operational amplifiers are connected in an advanced topology that delivers precise RIAA equalization and retains all the good sounds while suppressing noise and bad harmonics that create an uncomfortable feeling while listening.
Audio Grade Electrolytic Capacitors were also used, which proved to be the best at low frequencies so that the sound obtained has a very precise and powerful bass.
Phonio has MM and MC inputs that you can easily choose. It also offers various resistive and capacitive loading options in order to optimize the sound of the MC cartridge.
The aluminium case of the Phonio screens the internal circuit from any RFI signals while keeping the EMI of the power transformer far away from the phono stage.
In the power supply, we have an ultra-low noise LDO combination with over 5000uF of filter capacitance. It has thermal overload and short circuits. Inside of the Phonio, there is again low noise LDO-s in combination with BJT-s ultra-low noise power supply topology.
Linear Power Supply
With the Phonio you also get a low-noise linear power supply that is built without compromise, using the best components and the latest circuit design. The Auris linear power supply is reliable, simple and produces minimal noise.
It is made only for the needs of our device in order to obtain the best features and efficiency and is specially designed to exceed your expectations. It also has protection against current overload, short circuit and thermal overload according to the highest safety standards.
