1. VOLUME knob
This adjusts the total volume level of the unit’s internal speaker.
2. CROSSOVER knob
This adjusts the frequency range played back from the unit’s
speaker. Adjust this according to the low-frequency playback
capabilities of the connected device, as well as the
performance environment.
The relationship between the CROSSOVER knob indicator
and the active frequency range is shown below.
3. BOTTOM switch
Setting this switch to ON allows you to play the low end
with even greater power and punch.
Use this switch according to the input source as well as the
performance environment.
The BOTTOM switch is useful in the following situations.
• When you want to produce special low-frequency sounds
in a range beyond what ordinary subwoofers can handle.
• To get the low bass effect at low volume levels.
• When the connected device features sufficient low-
frequency playback, but the proper volume balance with
the KCW-1 cannot be attained with the CROSSOVER and
VOLUME knob.
* The BOTTOM switch affects only the speaker output.
4. PHASE switch
Setting this switch to INV inverts the phase of sounds played
from the KCW-1’s speaker.
Ordinarily use the KCW-1 with this switch set to NOR.
Switch the setting as needed according to conditions where
the unit is being set up to achieve greater volume in the bass
range.
The PHASE switch is useful in the following type of situation.
• The KCW-1’s low-frequency sound may not be fully
apparent when the placement relation or room acoustics
cause phase discrepancies between the KCW-1 and the
connected device.
Switching the PHASE switch in such conditions can allow
you to achieve greater volume in the bass range.
* The PHASE switch affects only the speaker output.
5. FOOT SW jack
You can connect a momentary-type foot switch (the optional
DP-2 or BOSS FS-5U) and use the switch to turn the output of
the KCW-1’s speaker on and off.
* Switching with the foot switch affects only the speaker output.
INPUT Section
6. INPUT jacks
Signals from devices equipped with a SUBWOOFER OUT
connector are input here. For instructions on connecting to
devices not equipped with any SUBWOOFER OUT, refer to
“Instructions for Connecting to Devices With No
SUBWOOFER OUT” (p. 9).
Two types of connectors are provided: XLR connectors and
1/4” phone jacks. Use the type of connector matching the
device you are connecting.
These accept level input of +4 dBu.
