DSPeaker ANTI-MODE 2.0 DUAL CORE Owner's Manual page 30

✗ No sound: Check the connections. Check that you have selected the correct input
(ANALOG, USB, or S/PDIF). Use the INPUT button on the remote controller to select
the correct input. Check that mute is not active and that the volume level is not too
low. Check that you have the correct output. Use the OUTPUT button on the remote
controller to switch between the analog (RCA and XLR) and digital (S/PDIF Toslink)
outputs. Note that you can use the room measurement's level check tool to
generate noise and confirm that the output is functioning.
✗ No sound / bad sound from S/PDIF digital input: In addition to the above,
check the digital signal format of the audio source. Only PCM input is accepted,
compressed formats are not supported. Please note that the Anti-Mode 2.0 Dual
Core does not accept 192 kHz sampling rate. Check that you have the latest
firmware.
Note: when using the USB input, the PC decodes any compressed format before
passing the audio in PCM format to the Anti-Mode 2.0 Dual Core.
✗ Not enough bass after calibration: a rather common first impression after
listening to years of resonance-infested bass. You slowly get used to the missing
resonances, but if the bass level is still too low, use the following methods. If your
system has subwoofers, their volume can be adjusted after the calibration. With
loudspeakers (as well as on subwoofers) you can use the House Curve or Parametric
filter tool to increase the bass to match the preferred level and tone. You can also
adjust the dip compensation value from the Audio Settings menu.
✗ Custom filters get disabled: this can happen for two main reasons. First of all,
when you start the calibration, all filters are disabled automatically. Even if you
cancel the calibration before a new room correction is applied, the disabled filters
are not activated with the exception of infrasonic and high/lowpass filters. The filter
designs do not vanish, however. You can simply re-enable them after the calibration.
Another possible reason is running out of computational resources. Even though
Anti-Mode 2.0 is equipped with two very powerful processors, even their capacity is
not infinite. If too many complex filter structures would exceed the CPU limit, the
system automatically disables one or more of the least significant filters to not
exceed the available resources.
✗ Problems with room correction are usually ultimately caused by a bad room
calibration analysis. The single most important factor for successful room analysis is
to make sure that the calibration volume is sufficiently high. Sometimes the
automatic level detection may indicate "Volume OK" even when it is in fact too low.
