REAR PANEL CONNECTIONS
Figure 1 shows the connections on the rear panel of the CHT-8R, CHT-10R and CHT-12R.
Figure 2 shows the connections on the rear panel of the CHT-15R.
Following are brief descriptions of the connections described in Figure 1 and 2. More detail on these connections
can be found on the next page.
(1) LOW-PASS CROSSOVER
Use this knob to select the high-frequency range at which you wish to cut off the signal to the subwoofer.
when the knob is turned all the way to the left, the Subwoofer Direct feature is invoked and the subwoofer
plays all frequencies up to 200 Hz.
(2) VOLUME Control
This control allows you to balance the output from the subwoofer to the main speakers in your system.
This control should be set to achieve similar volume level from between both the main speakers and
subwoofer. when pressing volume up or down, the speed at which the power light blinks indicates
subwoofer volume - the faster the blinking, the louder the unit plays. After the volume is changed (up
or down), there will also be 2 sets of center leD blinks. Slower blinks represent tens and faster blinks
represent ones. If the leD blinks 3 times, pauses, then blinks 6 times, this means that the volume is set
at 36. The volume range is from 1 to 99.
Note: Volume is also controllable by using the supplied remote, when defaults are restored. The de-
fault is 35 out of 100.
WARNING: Some manufacturers preset their receivers with the Sub-Out channel signal at a
minimum level. It is very important to verify that your receiver Sub-Out channel is set to
the same output as your front right and left channels. Refer to your receiver manual for the
individual channel level adjustment procedure. If your receiver Sub-Out channel is set too low,
the subwoofer may appear to have a weak output, it may sound noisy or distorted, and the
Auto-On/Off feature may not work properly.
(3) AUTO ON/OFF Switch
The Auto-On/Off feature allows the subwoofer to turn itself off when not in use.
- With the Auto-On/Off switch set to ACTIVE, the subwoofer will monitor its input, and if there is no
signal present for approximately 15 minutes, it will shut down and go into standby mode. As soon
as a signal is present again, the subwoofer will immediately turn itself back on.
- With the Auto-On/Off switch set to INACTIVE, the auto-on/off feature is bypassed. The subwoofer
will remain on until the power switch is turned off.
WARNING: If the Sub-Out channel signal level from your receiver is too weak, this feature
will not operate properly. See Volume Control section (above).
