This can occur especially in noisy environments and/or with limited band
subwoofers. When calibrating a subwoofer system, always disable subwoofer's
integrated low-pass filters or set them to their maximum cut-off frequency. You can
enable them after the calibration process, or utilize Dual Core's digital precision low-
pass filters that are probably more adjustable and capable. It is also important to try
to avoid all other cables running along the microphone cable, as they might induce
errors through the microphone shielding. Make sure you do not open or close doors
during calibration, as they tend to have much greater impact to the room response
than expected. After these checks, recalibrate and verify that the before / after
graphs are looking good. If the problems persists, contact
DSP
eaker support. It
speeds up the troubleshooting process if you have a picture taken of the before /
after graphs (with a camera) or have exported the responses to a file using USB.

Volume jumps each time USB is selected
If you have selected USB Volume:
By Computer
in the
Input Settings
menu, when
you select USB, your PC sets the last volume setting it has previously used with the
device. That setting is restored each time USB input mode is selected while the unit
is attached. With the
By Computer
mode the
VOL+
and
VOL-
buttons are reported
to the PC, which performs the volume control operation. You can also adjust the
volume using the master volume control on the PC.
If you select USB Volume:
By Remote
in the
Input Settings
menu, volume control
from the PC is ignored, and
VOL+
and
VOL-
buttons adjust the volume directly.
Mute can still be controlled by the PC.
Be aware that volume controls in an audio or multimedia player program may use
digital volume control, which causes the digital data to be scaled. So check that you
use master volume. Using the master volume control does not cause any precision
to be lost, because it controls the analog volume at the output of the Dual Core.
✗
The Anti-Mode 2.0 Dual Core does not show up in USB
The unit will only act as a USB device when the USB audio input is selected, or when
you have selected the
PC Link
option from the
Settings
menu. In the former case you
will get standard USB Audio device (asynchronous mode) and human interface
device (some of the buttons in the remote controller are reported to PC when so
configured). In the former case you will get a USB Mass Storage device, i.e. a
removable disk. You do not need to install any drivers to use any of these devices.
