The Essential Link Between Your Vinyl Turntable and a Line Input
A vinyl turntable delivers a very low-level signal that requires appropriate gain and RIAA equalization before feeding an amplifier, active speakers, or an interface equipped only with "line" inputs. This is precisely the role of a phono preamplifier: to boost the signal level and restore the tonal balance imposed by record cutting. With its 40 dB gain and input level adapted to MM cartridges, this model belongs to the category of direct, efficient, and easy-to-integrate solutions designed to bring your vinyl setup back to life without relying on a dedicated phono input on the amplifier.
Who Is This Phono Preamp For?
This preamplifier is aimed at vinyl enthusiasts using a turntable equipped with a MM cartridge who want to connect it to a line input (AUX, LINE, CD, TAPE, RCA input of powered speakers, etc.). It is suitable both for a first Hi-Fi system and for a more advanced setup, as long as you are looking for a compact and low-noise solution capable of preserving the dynamics and details of your pressings. The presence of a ground connection is a real advantage for stabilizing the setup and reducing hum, especially with turntables sensitive to ground loops.

How to connect a turntable to active speakers with this preamp?
The turntable connects to the phono RCA input, then the line RCA output is connected to the line input of the active speakers. A ground terminal allows connection of the turntable’s ground wire to reduce hum.
What gain is offered for an MM cartridge?
A gain of 40 dB is applied to the MM signal, for an input sensitivity of 3.14 mV. This level is suitable for connection to an AUX, CD, TAPE, or LINE input.
Is the RIAA equalization accurate on this phono preamp?
The RIAA equalization has a precision of plus or minus 0.3 dB maximum. The frequency response extends from 10 Hz to 50 kHz at -3 dB, with distortion below 0.015%.
What are the enclosure dimensions and its power supply?
The enclosure measures 100 x 45 x 93 mm and weighs 0.292 kg excluding power supply. A separate 24 V DC power supply is provided, while the power on-off switch is located at the rear.
