Changing the PCM filter

You can use the filter settings to change how music sounds when listening to PCM data.
Filters are a personal choice. A different filter setting is stored for each sample rate.

4. Tap

to select Filter.

5. Tap

to change the PCM filter.

Filter 1. The filter has the best rejection of unwanted Nyquist images with the sharpest
roll-off, but poor transient response.

Filter 2. The filter has a more relaxed image rejection and better transient response.
Filter 2 is recommended for orchestral music.

MQA filter. Recommended and only available for MQA audio files. You can select this
filter in addition to the other PCM filters.

Changing the DSD filter

The DSD filter is active when you are playing DSD files or upsampling PCM data to DSD.

If you are playing a DSD file or upsampling to DSD, and the level of hiss at the
output is high, your amplifier may not work well with wideband DSD signals. Try
setting the DSD filter to Filter 2 or 3.

Filter 1. The default setting, which gives the widest bandwidth and the highest level of
out-of-band noise.

Filter 2. Reduces the out-of-band noise and bandwidth.

Filter 3. Reduces the out-of-band noise and bandwidth further.

Filter 4. Recommended for troubleshooting only. Sharply reduces the out-of-band
noise and also limits the bandwidth to 25 kHz.
