PARTS
-
Power ON/OFF
This is the power switch. -
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. -
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. -
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. -
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. -
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.
-
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. -
RCA analogue output
This is an analogue output. -
Ground
This is the ZEN Phono’s ground, please connect it to the turntable’s grounding wire. -
RCA analogue input
This is an analogue input. -
Gain channel switch
This button cycles between 4 gain levels: -
corresponds to MM (>2mV)
-
corresponds to MC HIGH (≤2mV)
-
corresponds to MC LOW (≤0.5mV)
-
corresponds to MC V-LOW (≤0.25mV)
Please adjust the gain channel switch in accordance with your preference and your turntable’s specifications. -
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.
