Auris Audio Phonio Light

Auris Audio Phonio Light

Auris Audio Phonio Light is a phono preamplifier with separate MM and MC inputs selected using switches at the front of the device, and has one output: RCA.

In the Phonio Light, Sound Plus operational amplifiers are connected in an advanced topology that ensures accurate RIAA equalization and preserves all the good sounds in the audible frequency range, while suppressing hum and bad harmonics that create an unpleasant sensation during listening.

The device comes with a 16V AC adapter that is small enough not to get in the way, and at the same time can be detached from the device, avoiding interference and allowing the power circuit to minimize noise as much as possible.

In the device, we have capacitors with a capacity greater than 5000uF for better filtration, but that’s not all, because to achieve an ultra-low amount, we also use an LDO in combination with a BJT to obtain a power supply topology with a high PSRR (power supply rejection ratio).
