INPUT
These connections accept low and high level signals. Connect to source unit pre out connections with high quality RCA connections. Use the
included high level to RCA adapter to connect high level (speaker) output signals from your source unit to the inputs of the X-Bass pro.
REMOTE
Connect the included remote controler to this connection.
OUPUT LEVEL
This switch sets the output level of the X-Bass Pro.
OUTPUT
These connections are the pre outs to connect to you amplifiers/processor.
Auto Turn On
this switch is used to select if the X-Bass Pro switches on with DC Offset signal or with Audio signal when high level (
SPK IN
)
input signals are used.
INPUT LEVEL
This switch is used to select if the X-Bass Pro is used with high level (
SPK IN
) or with low level (
PRE IN
) input signals.
Q
This dial sets the Q-factor of the Parametric Bass circuit.

Settings
To setup your X-Bass Pro correctly you need to know whats going on inside the processor.
As already mentioned the X-Bass Pro restores low bass frequencies that were filtered out. This processing is always active inside the X-Bass Pro.
Because the interior of the car, placement of the speakers in the car also have a huge effect on the bass response X-Bass Pro has a
Parametric Bass circuit on board.
The
FREQ
dial lets you set a center frequency. The
Q
dial sets the filter shape or Q-factor for the circuit, in other words how many frequencies around
the chosen center frequency are included.
The remote bass control allows you to adjust the level of added extra bass to your system.
The
OUTPUT LEVEL SWITCH
correct setting depends on your amplifier input sensitivity and the subwoofer(s) used:
OUTPUT LEVEL
Amplifier input sensitivity
Subwoofer(s)
2.5V
Upto 3V input voltage
6” to 8”
5V
Upto 5V input voltage
8” to 10”
10V
Upto 10V input voltage
12” and up
In case of difficulty
Almost all problems can be eliminated by re-checking connections and settings in your system. Follow the steps below as a guide.
If you cannot solve the problem, consult your XFIRE AUDIO installation professional.
NO SOUND - POWER LED IS OFF
1. Check the inline fuse(s) in the positive power cable, replace these if needed.
2. Check the negative power cable connections.
3. Check if the system operating voltage is between 9V - 16V DC, our processors and amplifiers have a high and low voltage protection.
4. Verify source unit operation.
5. Check connection of REMOTE TURN ON wires. If steps 1-4 are OK your processor and amplifier should switch ON and the power LED should light up.
NO SOUND - POWER LED IS ON
1. Check the RCA cables are properly connected on the source unit and processor.
2. Check the RCA cables for damages and replace the cables if needed.
3. Check the speaker cables for damages and if they are connected properly, replace cables if needed.
4. Check if the speakers are damaged and replace if needed.
NO SOUND - PROTECTION LED IS ON
1. The speakers connected have an impedance under the specified load or the speakers/speaker cables have a short circuit.
2. The amplifier runs really hot, mount the amplifier as recommended in the INSTALLATION section of its manual, check the impedance of the
speakers and measure if the operating voltage is within 9V - 16V DC.
3. Check for DC offset on the RCA inputs, if so check the source unit and RCA cables for damages.
POOR BASS RESPONSE
1. Check if all speakers are connected with the right polarity, speakers connected out of phase will cancel each other resulting in a poor bass response.
2. Check if the connected speakers/subwoofer(s) are OK, replace if needed.
ENGINE NOISE
1. Use only high quality shielded RCA cables.
2. Ensure that all signal transfer wires (RCA, speaker cables etc.) are kept separately and away from power and ground wires.
3. Ensure you have only ONE ground connection (star ground) for all your audio components.
4. Ensure that the point of ground is 100% metal which has been sanded free of rust, paint etc.
5. “Optional”Replace the OEM ground cable from the battery with the proper gauge wire (see Power Wiring Selection Chart in the amplifier manual).
