Home/Office Operation
Use the Active Speaker Box easily at home, office, shop or anywhere with an 110V wall
socket outlet.
Connect the power cord to the Active Speaker Box and plug into a wall
socket outlet; then use the on/off switch to turn on. Use a USB or SD/MMC card with
your favorite songs. You can also connect an mp3 playing device to the AUX input.
Trouble Shooting
Refer to lists below and follow suggested procedure. Speakers and their wires should be
tested first
.
No Sound/No Output
a.
Confirm all connections are firmly connected.
b.
Check in-line and built-in fuses. Both “+12V” and “REM” terminals must have +12
Volts
c.
Make sure the unit is plugged in and the switch is in the on position
d.
Confirm signal source (Car Radio/Deck/ line-out converter.) is connected and
supplying an output signal. Switch to AUX mode.
To confirm that the Amplifier is working, connect an RCA audio component cables
to an audio device with audio component outputs that is known to work. If you hear
a sound you know the car radio out-put is the problem. Or briefly tap the center pin
of each (disconnected) RCA plug on the other (
disconnected
) end with your finger.
This should produce a noise (
feedback
) in the speakers. Leave the Active Speaker
Box component audio plugged in.
e.
File format (MP3) or system file format maybe incorrect if using USB/SD card mode.
Unit will switch to FM mode if it does not recognize format.
f.
Check both volume controls, turn the dial on the side panel or press and hold the
Next/Vol. + button on the top panel (0 - no volume, 16 - loudest).
Low Sound/ Weak Output
a.
Check both volume controls.
b.
MP3 file has too low bit-rate
c.
Car’s sound signal too low.
d.
Adjust volume on music player in AUX mode.
Noise in Audio
a.
If noise has a “whine” that goes up and down with engine speed, confirm that
Amplifier and any other source units (Radio, EQ, X-over etc.) are properly grounded.
Confirm the RCA wires are not near the POWER or REM wire.
b.
A “clicking” or “popping” noise at a rate that follows engine speed is generally
induced by the vehicle’s ignition system. Confirm that the vehicle is equipped with
resistor plugs and plug wires. Or, ignition system may need service. Ground loop
insulator part may be needed.
c.
Distortion is heard, you must turn down the speaker to avoid damage.
d.
Speaker and input wires should not be ran next to wires that interconnect lights and
other high power accessories or equipment.
e.
If above steps do not improve/clear noise interference, the system should be
checked by a professional. Extra parts may be needed to correct your vehicles
specific issue.
