Thank you for purchasing the Phono from the ZEN Air series.
The ZEN Air Phono is a single-ended MM/MC phono stage.
1. Power ON/OFF
This is the power switch.
Note: If the unit has been powered on for a while, you need to press the power switch
twice to turn it off. This is because the MCU goes into sleep mode for less noise, so you
get to enjoy the best sonics!
2. MM input LED
This is the MM input indication. Use this setting for MM
cartridges with output voltage 2mV and higher. Please select
MM on the gain switch at the rear.
3. MC input LED
This is the MC input indication. Use this setting for MC
cartridges with output voltage < 2mV. Please select MC on
the gain switch at the rear.
4. SUBSONIC Filter ON/OFF and Gain switch
unlocked
This is the SUBSONIC filter switch (short press)
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 have
little effect on the sound quality.
Gain switch function unlocked (short press)
To change gain after the unit has been on for more than 10
minutes, short press this switch to unlock the rear gain switch (8).
Tip: To protect your device, the gain switch (8) will enter lock mode after 10 minutes and
will need to be unlocked each time you operate it.
