Step 3
Listening Test
To ensure that all connections have been made correctly, turn on your system and begin playback of material you are famil-
iar with. Start off by listening at a low volume, then slowly raise the volume to a comfortable listening level. A prope stereo
image should be present. If the loudspeakers do not produce a solid stereo image, please verify the wiring to ensure that the
polarity of the connection is not reversed.
Powering Up the Subwoofer
A) On/Off Switch:
Your subwoofer has an On/Off switch. Once connected to your receiver and plugged into the wall outlet, the Sinclair Audio
subwoofer will need to be turned on and can be left in the "auto" position so that once it senses a signal coming from your
receiver, it will automatically turn on and will turn off into Standby mode after it does not sense a signal for 5 minutes.
B) Setting the Volume and Crossover Frequency.
Crossover:
The Frequency control determines the frequency below which the subwoofer will play. This frequency is manually controlled
and is continuously variable between 35-180Hz. You can experiment with which position works best with your main speak-
ers by turning this control until the sound of the low frequency coming from the subwoofer is nicely blended with the sound
of your main speakers.
Frequency setting tip:
When using small speakers (speakers with a 6" or less main woofer) set this control toward the clockwise position. When
using larger speakers (speakers with an 8" or more main woofer) set the control closer to the counterclockwise position.
Gain:
When setting the Gain control at the subwoofer, begin with your main speakers playing at a
normal listening level and the Gain control at the subwoofer completely in the off position
(counterclockwise position). Then, begin to turn up the Gain at the subwoofer slowly (clock-
wise) until the desired bass response is achieved. Bass output will then be regulated by your
A/V receiver's volume control.
Gain setting tip:
Have one person sit at the regular listening position, and a second person turn up the Gain at the subwoofer until the desired
bass output is achieved at the listening position. Remember most natural sounding bass results when bass reproduction is bal-
anced with the main speakers.
Phase
The phase control will fine tune the bass performance. Have one person sit in the listening position and a second person tog-
gle the switch between Normal and Reverse to achieve the desired bass output.
Maintenance
Sinclair Audio loudspeakers are finished in a high gloss lacquer and black wood grain vinyl. Cleaning the loudspeakers should
be done with a damp cloth. Chemical cleaners should be avoided, as they may damage the finish.
