MM and MC preamp

The ZEN Phono 3 accepts moving magnet and moving coil cartridges, in high, low or very low output versions. Its 158 x 115 x 35 mm, 456 g case sits easily next to the turntable. It keeps pace with a growing vinyl system, from a first MM cartridge to a demanding MC.

Independent gain and loading

Four gains of 36, 48, 60 and 72 dB and four input impedance settings combine freely thanks to the load button. MM and high-output MC cartridges see 47 kohms with 100 or 200 pF, low-output MC 1 kohm, 400 or 100 ohms. The intelligent subsonic filter removes only the warp of uneven records and leaves the music's bass intact, without group delay.

Balanced and RCA outputs

At the rear, a balanced output joins the RCA outputs, alongside the ground post and the gain selector. In balanced mode, response extends from 20 Hz to 80 kHz at -3 dB and output voltage exceeds 19.98 V into 100 kohms. Channel separation stays above 75 dB at 1 kHz in every mode.

Clean power, precise RIAA

An isolated 1.2 MHz clean power supply amplifies only the music, with an equivalent input noise of -151 dBV. RIAA equalisation uses several TDK C0G capacitors in parallel and stays within 0.15 dB of the curve from 20 Hz to 20 kHz. The unit runs on 5 V DC and accepts an iPower2 supply for an even quieter background.
