BassLink II (4sc, if installed)
• PROBLEM:
POWER LED not lit.
CAUSES and SOLUTIONS:
1. Fuse is blown and needs replacement.
2. Head unit not functioning properly. Check
remote voltage, and power, ground or
remote connections.
• PROBLEM:
POWER LED is lit but there is no bass.
CAUSES and SOLUTIONS:
1. Inputs are not connected. Check connections.
2. Head-unit fader control is not set properly.
Adjust head-unit fader control to feed audio
signals to BassLink II.
• PROBLEM:
BassLink II sounds muddy or distorted.
CAUSES and SOLUTIONS:
1. Gain is set too high and SERVO LED is lit
constantly. Readjust GAIN control (see
Tuning BassLink II on page 6).
2. Bass is set too high. Readjust BASS BOOST
control (see Tuning BassLink II on page 6).
3. Head-unit output is distorted or blown. See
your authorized Infinity car audio dealer.
• PROBLEM:
No output from BassLink II when head-unit
fader control set to front or rear (in a 4-channel
connection).
CAUSE and SOLUTION:
Input connections are improperly wired. Verify
all connections (see Applications starting on
page 3).
• PROBLEM:
BassLink II turns on before head unit is com-
pletely on and produces a “thump” sound.
CAUSE and SOLUTION:
For speaker-level connections, head unit is
producing a false turn-on signal. On BassLink
II’s side panel, slide AUTOTURN ON to OFF.
• PROBLEM:
BassLink II’s POWER LED remains on after head
unit is turned off.
CAUSE and SOLUTION:
For speaker-level connections, this is normal
operation when AUTOTURN ON is set to ON.
BassLink II will remain on another 5 to 10 min-
utes after sensing that audio signals are not
present before shutting down.
• PROBLEM:
BassLink II produces a loud humming noise
with the system OFF when using speaker-level
inputs.
CAUSE and SOLUTIONS:
This problem is caused by a feedback loop
between your speakers and the high-level inputs
of BassLink II.
Choose one of the following solutions:
1. Connect a wire from the REMOTE terminal on
BassLink II to the remote turn-on of your head
unit or to the vehicle’s accessory circuit. On the
control panel, slide the AUTOTURN ON switch
to the OFF position.
2. Connect the supplied capacitors between
each of the speaker outputs of the head unit
and the speaker’s positive lead, as shown
in Figure 18. Connect each positive lead of
BassLink II’s high-level inputs to the head-unit
side of the capacitors. Use one capacitor per
speaker input channel.
