Phono One MM Pre-Amplifier
i2Audio’s PhonoOne is a small, yet excellent sounding phono preamplifier for MM pick-ups. The design achieves a very low group delay distortion which results in a very natural replay of any kind of music. With its input impedance of 47kΩ/100pF and a fixed gain of 40dB it suits a wide variety of MM systems. Highly linear SMD foil capacitors and high performance integrated operational amplifiers guarantee low noise and distortion.
Only a 12V DC power supply with minimum 100mA current capability is required. The onboard power management generates a symmetrical, low noise supply with ±8.5V for the amplifier stages which is key for a well sounding preamplifier.
The Phono One can be purchased from HiFiBerry’s webshop.
