7. Balanced 4.4mm analogue output
This is an analogue output via 4.4mm > XLR or other balanced
interconnects. You could use this for an active speaker or an
amplifier.
Tip: As ZEN Phono is balanced, this is the recommended output.
8. RCA analogue output
This is an analogue output.
9. Ground
This is the ZEN Phono's ground, please connect it to the
turntable's grounding wire.
10. RCA analogue input
This is an analogue input.
11. Gain channel switch
This button cycles between 4 gain levels:
1. corresponds to MM
(>2mV)
2. corresponds to MC HIGH
(≤2mV)
3. corresponds to MC LOW
(≤0.5mV)
4. corresponds to MC
V-LOW
(≤0.25mV)
Please adjust the gain channel switch in accordance with your preference and
your turntable's specifications.
12. DC 5V power
Please connect the ZEN Phono to the enclosed power supply.
The ZEN Phono must ONLY be powered by 5 volts.
For best performance upgrade the enclosed power supply to a super-silent
iPower 5V or the ultra-low noise iPower X 5V power supply.

Thank you for purchasing the Phono from the ZEN series. The
Phono is a balanced MM/MC phono stage.
1. Power ON/OFF
This is the power switch.
2. MM input LED
This is a MM input suitable for MM cartridges with the output
voltage higher than 2mV. Please select Gain 1 at the rear.
3. MC HIGH input LED
This is a MC HIGH input suitable for MC cartridges with the
output voltage less than or equal to 2mV. Please select Gain 2 at
the rear.
4. MC LOW input LED
This is a MC LOW input suitable for MC cartridges with the
output voltage less than or equal to 0.5mV. Please select Gain 3
at the rear.
5. MC
V-LOW input LED
This is a MC
V-LOW input suitable for MC cartridges with the
output voltage less than or equal to 0.25mV. Please select Gain
4 at the rear.
6. SUBSONIC Filter ON/OFF
This is the SUBSONIC filter switch.
The iFi-designed subsonic filter will intelligently detect whether a
subsonic frequency is a warp or a bass note. It will eliminate the
warps and let all the bass and mid-range frequencies pass
through untouched. Therefore, it will not affect the sound quality.
