Aura SW-T20A Owner's Manual

Installation recommendations
Select the most suitable location for installing the subwoofer depending on the brand of car and the
space available in the trunk. The best in terms of sound quality and the safest place to install a
subwoofer is the space behind the rear row of seats on the boot floor.
To prevent the subwoofer from overheating, there should be nothing around it. For effective cooling,
air must circulate freely around the subwoofer.
* Note: It is difficult to avoid shaking or bumping while driving, so the subwoofer should be securely
fixed. It is recommended to use the straps (supplied with the subwoofer) to secure the subwoofer to
the tube-type enclosure.
Setup recommendation
1. Set the level control on the subwoofer "LEVEL" to the minimum value (far left, 2V).
2. Set the crossover switch to "L.P.F.". The "FILTER" control is in the middle position.
3. Set the volume on the radio tape recorder to the maximum level at which sound distortion will not
occur. If you hear distortion, reduce the volume on the radio tape recorder until the distortion
disappears. Leave the volume control of the radio at this level while tuning the system.
4. Gradually increase the subwoofer level with the "LEVEL" control until you hear distortion in the
sound. If distortion occurs, turn the "LEVEL" control back slightly.
5. Adjust the cutoff frequency with the "FILTER" knob. When listening, make sure that there is no
audible distortion.
High power car sound systems are capable of delivering sound pressure levels exceeding 130 dB.
Do not listen to music at high volume levels for long periods of time, and while doing so, make sure
that the subwoofer does not overheat.
