CHT-Q Series User’s Manual
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. Be very careful to avoid any loose strands or frayed wires that may result in a
short, which may damage your equipment. Cables of extremely large size are not required due
to the low current draw of this type of connection. Extremely large gauge wire may not properly
fit in the terminals, resulting in a poor connection and possible short circuits.
This section addresses usage of your CHT-Q subwoofer.

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 mode. The woofer will not play and the LED will turn
off. The unit will remain in this mode until the POWER button
is pressed again. To fully deactivate (i.e. power down) the unit,
turn off the power switch on the back panel.
• MUTE — This button mutes the subwoofer’s output. The LED
on the sub will show 00 if the unit is muted. To unmute the
subwoofer, press the MUTE button again and the original
volume setting shows on the LED.
• EQ — This button automatically equalizes the subwoofer’s output so that it sounds best for
its position in the room. To use this feature, remove the grille and plug the supplied
microphone into the Mic-In jack on the front baffle of the sub and place the mic in your
preferred listening position. Then press EQ on the remote for about 2-3 seconds. The
subwoofer emits 12 “sweep tones” that span the frequencies between 20 and 150 Hz. The
LED displays “AU” during the Auto-EQ process. After the sweeps are complete, the unit saves
its EQ settings and returns to normal operation. To prevent accidental invocation of the EQ
feature, you must hold down the EQ button for 2-3 seconds before the EQ sweeps begin. If
the mic is not plugged in, the subwoofer sweeps twice then reverts back to normal functioning
without changing any EQ settings.
• PHASE — These buttons allow you to optimize the subwoofer’s bass performance relative to
the speakers and your listening position. Play some bass heavy music. While listening, push
one of the four phase buttons, listen for a few moments, and then press the next phase
button. In most installations, one of the four button positions will offer an audibly better blend
of subwoofer and speakers. The LED will show the phase selected by showing “PH” followed
by the phase number: 0, 90, 180 or 270.
