Cookie-Cutter ‘Sub-Sonic Filter’

Tom Evans who makes very nice phono stages made the following astute comment:

A rumble filter simply adds to the bass cut making your already “cut” records sound bass light. Plus, it “time-steps” the bass in relation to the higher frequencies (where our hearing is most sensitive) so much so it can confuse the ear into believing the bass is playing out of tempo.

iFi solution:

Since the very first iPHONO launched in 2012, we have used our own in-house ‘Subsonic Filter’. It made it into the iPHONO2 and the iPHONO3 and now, the ZEN Phono which is the very first time this filter is seen in such an affordable price level.

As there is only minimal vertical modulation remaining at very low frequencies with an an actual cut LP that is playable, we know that “vertical modulation” at low frequencies must be warp.

So we designed a filter to take advantage of this.

This is not artificial but real knowledge. By understanding fully how LPs are cut and replayed,  it is possible to filter record warp strongly without at the same time attenuating low bass or adding group delay.

The perfect match

Just connect between your headphones/iEMs and the output of your smartphone, DAP (digital audio player) or music source to simply and instantly improve playback.  

  • Regains 16.24 Bit audio resolution
  • 12.24dB noise reduction
  • 0% frequency loss

Adjust the desired volume ‘on-the-go’ to ensure a safe, comfortable listening level whilst enjoying lower background noise and maximum dynamics.

Sensitivity solved

The iEMatch+ gives you two sensitivity settings:

  • High – for high sensitivity headphones (reduces gain by 12dB)
  • Ultra – for ultra sensitivity headphones (reduces gain by 24dB)

We suggest trying both to see which listening level works best with your headphones and your listening preferences.

Wired. And then some.

The minZ™ cable construction is a custom helix design. It is minimised in both capacitance and inductance.

The minZ™ helix construction also provides intrinsic shielding and protects the cable from RFI and EMI noise.

This ensures the cleanest possible transfer medium.

Balanced or Single-Ended? iEMatch+ automatically converts to give you the best listening experience using the 3.5 TRRS-Balanced headphone jack.

There is no need to switch to SE to use a single-ended headphone with a TRS (3-connection) plug. The conversion to single-ended is automatic. The switch can be set to BAL or SE with no ill effect.

If using a balanced headphone with the TRRS connection, leave the switch on BAL. If you discover a channel is missing, please switch to SE as your music source only supports single-ended operation.

If using a headphone with a microphone, please switch to SE. The microphone will be disabled.

Do you know that you normally lose at least 2Bits of resolution when listening to your favourite tracks at normal listening levels?

This is because you can’t listen at full volume. Well, you can but you run the risk of damaging your hearing.

Using the iEMatch+ enables you to turn up the digital volume and get those 2Bits back safely.

The iEMatch+ uses premium components throughout.

  • 6N silver/copper matrix wiring with FINAL 6063-T5 aluminium-magnesium shell
