TiK SUB - JBL Audio User Guide / Operation Manual. Page 4

If a line level signal is not available, connect loudspeaker cable from
the receiver/amplifier’s speaker terminals to the subwoofer’s Speaker
In Left and Right. Speaker Out Left and Right terminals are provided
for connecting the main speakers to the subwoofer, if no direct
connections are available from the receiver/amplifier. Always
observe correct polarity, connecting plus-to-plus and minus-to-
minus.

When using speaker level inputs, no signal is available from the line
level outputs.

OPERATION

After checking that all necessary connections have been correctly
made, connect the AC power cord to an active AC wall outlet. Turn
the subwoofer on using the rear panel power switch. Once
connected, the TiK Sub will automatically turn on when a signal is
present. When no signal is received for approximately 15 minutes,
the subwoofer will go into standby mode and remain in standby until
a signal is detected. Power consumption is minimal when the
subwoofer is not receiving a signal.

The front panel LED will glow amber when the subwoofer is On. It
will glow red when the subwoofer is in Standby.

The Level control adjusts the volume of the subwoofer relative to the
rest of the system. Proper adjustment depends on factors such as
room size, subwoofer placement, type of main speakers and
listening position. Adjust the subwoofer level so that bass
information is naturally integrated with the sound of your main
speakers. If the subwoofer is connected via DSP In to a JBL TiK
Master Sub, the Level control is automatically bypassed.

The crossover frequency control marked Filter determines the
highest frequency your subwoofer will reproduce. It should be
adjusted to create a seamless transition from the subwoofer to the
main speakers. Experiment with this adjustment to find the
crossover frequency that sounds best with your speakers.

When the control is at the "30 Hz" position, very few high frequencies
will be heard. This position is best suited to very large main speakers.
For most systems, the control should be set somewhere near the mid
position. For listeners using very small speakers, best results will be
obtained with the control at the "150 Hz" position.

If the subwoofer is used with an external crossover or with a
preamplifier/surround processor with dedicated subwoofer outputs,
press Filter Defeat to bypass the subwoofer’s internal filter. If the
subwoofer is connected via DSP In to a JBL TiK Master subwoofer,
the Filter is automatically bypassed.

The Phase switch is used to adjust the relative polarity of the
subwoofer. Listen to your TiK Sub and main speakers with the switch
in the "0°" position, then listen to the same material with the switch
set to "180°". Decide which sounds better and leave the switch in
this position. Repeat this procedure, if you move the subwoofer. 
If the subwoofer is connected via DSP In to a JBL TiK Master
subwoofer, the Phase switch is automatically bypassed.

To fine-tune the deepest bass for the best match to your system,
room and personal preferences, adjust Contour in connection with
careful listening. The TiK Sub is designed to provide flat frequency
response in free air (away from all boundaries) with the Contour
control in the "Max." position. The TiK Sub is designed to provide flat
frequency response when placed in a corner with the Contour
control in the "Min." position. If you wish to reduce the level of the
very lowest frequencies turn the control toward ”Min.” This can be
particularly useful, if placement near walls or corners provides too
much bass reinforcement. If the subwoofer is connected via DSP In
to a JBL TiK MasterSub, the Contour control is automatically
bypassed.
