INTERCONNECT CABLES
When installing your new Velodyne subwoofer using the line level connections, you should always use shielded
phono cables. There are many high quality cables available today. It is recommended that you keep the length
of cable as short as possible to avoid any potential noise problems.
When using speaker level connections, use a high quality speaker cable that mates well with the connectors.

Remote Control
The features of the CHT-Q remote control are listed below.
NOTE: The CHT-Q remote can be attached magnetically to the back of the
subwoofer in the upper left hand corner.
• POWER — This button forces your CHT-Q subwoofer unit into standby

on the LED.

any EQ settings.
