RESTEK MINI RIA

Second-hand, in mint condition, without scratches. Supplied with manual and its original package.

MM/MC Phono Preamp

The MINIRIA is composed of two separate mono preamplifiers, each featuring two amplification stages and both passive and active RIAA equalization sections. The input sensitivity of the amplification stages is highly flexible, allowing for gain adjustment from +32 dB to +64 dB to compensate for volume differences across various cartridge systems.

The MINIRIA is equipped with output drivers that ensure optimal management of the connection with the preamplifier. With an output impedance of 50 ohms and a maximum current of 35 mA RMS, this preamp can handle long connection cables without compromising signal quality.

All electronic components in the MINIRIA are DC-coupled, meaning the preamp can reproduce the lowest frequencies with transparency and fidelity, free from distortion or phase issues. Noise and crosstalk are minimized, making them virtually imperceptible even to the most discerning listeners.
