Tip: There is no need to switch to SE to use a single-ended
Headphone with a TRS (3-connection) plug, 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 TRRS connection,
leave the switch on BAL. If you encounter a channel is
missing, please switch to SE as your music source only
supports single-ended operation.
If using a headphone with microphone, please switch to SE.
The microphone will be disabled.
3. iEMatch® for headphones/In-Ear-Monitors
Adjust 'on-the-go' the desired volume to ensure a safe,
comfortable level of music enjoyment whilst at the same
time, enjoying lower background noise and maximum
dynamics.
There are two sensitivity settings:
I. High: For high-sensitivity headphones.
ii. Ultra: For ultra-sensitivity headphones.
Tip: Feel free to try both and see which listening level works
best with your headphones and your listening preferences.
For the technically-inclined, High-sensitivity and
Ultra-sensitivity reduce gain by -12dB and -24dB
respectively.
Please note that with the iEMatch® in-line, you are able to
turn up the volume on the music source far more. In
extreme cases, this may cause the internal amplifier of the
music source to enter into 'clipping mode' and produce
unwanted audio distortion. This is no cause for alarm. If
this occurs, please reduce the volume or the sensitivity level
of the iEMatch® accordingly.
