MAXX-LINK MLX-100 BRIDGING MODULE FEATURE DESCRIPTIONS
END PANEL CONNECTIONS
MASTER OUT / SLAVE IN: The Master Out sends master signal to another MLX-100.
The Slave In receives a Master signal and all controls are bypassed on the unit.
BR-1 REMOTE CONTROL: Using an Rj45 cable, the BR-1 Bass Remote Module plugs
directly into the MLX-100 and allows you to adjust the Level from -20dB to 0 dB as well
as Normal and Bypass operations.
NORMAL: BR-1 is fully adjustable from -20dB to 0dB.

Linking 2 MLX-100s using Master/Slave operations
This application illustrates the method of linking 2 MLX-100’s using the Master/Slave features.
1. Connect the full range RCA outputs from the headunit to the MLX-100 #1’s inputs.
2. Connect a single RCA from MLX-100 #1’s MASTER OUT to MLX-100 #2’s SLAVE IN.
3. Swicth MLX-100 #1 into MASTER MODE and MLX-100 #2 in SLAVE MODE.
4. Adjust MLX-100 #2 as follows:
- The LOW PASS FILTER should be turned to 250Hz.
- The OUTPUT LEVEL should be turned to 1V.
- The SUBSONIC FILTER should be turned to 15Hz.
- The INPUT LEVEL should be at the 12 o’clock position.
- The PHASE should be turned to 0.
- The BOOST should be turned to 0dB.
- The Bandwidth should be turned all the way to the right.
- The FREQUENCY should be turned to 100Hz.
5. Connect POWER, GROUND and REMOTE to each MLX-100.
Now MLX-100 #1 controls MLX-100 #2 and you can run up to 10 linked pairs of amplifiers. Match all amplifiers as instructed
in the future application instructions.

MAXX-LINK MLX-100 BRIDGING MODULE APPLICATIONS
Mono bridging 2 standard mono amplifiers with no Master/Slave feature to a single subwoofer
This application illustrates the method of linking 2 Mono amplifiers to a single subwoofer.
1. Connect the full range RCA outputs from the headunit to the MLX-100 inputs.
2. Connect the RCA’s from the MLX-100 (A+ and A-) BRIDGING OUTPUTS to the amplifier INPUTS as shown.
3. The amplifier settings need to be adjusted as follows:
- The LOW PASS FILTER should be turned towards the highest frequency. (EXAMPLE: LOW PASS range = 35Hz to 250Hz, adjust to 250Hz)
- The SUBSONIC FILTER should be turned towards the lowest frequency. (EXAMPLE: SUBSONIC range = 15Hz to 35Hz, adjust to 35Hz)
- The PHASE should be at 0.
- The BASS BOOST/BASS EQ should be at 0dB.
- The LEVEL(gain) control should be turned to the 12 o’clock position.
4. The INPUT LEVEL control on the MLX-100 should be set to match the output signal voltage from your headunit.
5. The MLX-100 LOW PASS FILTER, SUBSONIC FILTER and PARAMETRIC BASS EQ settings should be adjusted for desired listening.
6. The MODE switch should be in the MASTER position.
7. The OUTPUT LEVEL should be at 1 Volt.
At this point you are ready to balance the speaker output from your amplifiers. For this procedure you will need a Digital Voltmeter.
- Switch the MLX-100 TEST TONE switch to the ON position.
- Adjust your Voltmeter so that it is measuring VoltsAC.
- Connect the positive Voltmeter lead to the (+)POSITIVE SPEAKER TERMINAL on amplifier #1.
- Connect the negative Voltmeter lead to the (-)NEGATIVE SPEAKER TERMINALon amplifier #1.
- Turn the audio system on, turn the volume all the way down, and ensure that there is no audio CD in your CD player.
- Start off with the input LEVEL(gain) settings of the 2 amplifiers at top dead center, or the 12 o’clock positions.
- While measuring the Voltage AC on amplifier #1, continue adjusting level control until you measure anywhere from 4-6 Volts.At that point, write down the
voltage on a piece of paper.
-Connect the voltmeter to the speaker terminals of amplifier #2.
- Now adjust the input gain control of amplifier #2 for the same voltmeter reading as you had noted down .
8. Once the amplifiers have matching output voltages, you should turn the 65Hz TEST TONE to the OFF position.
9. Connect the speaker + terminal to the POSITIVE SPEAKER TERMINAL of amplifier #1.
Connect the speaker - terminal to the POSITIVE SPEAKER TERMINAL of amplifier #2.
Connect a wire link between the NEGATIVE SPEAKER TERMINALS of the two amplifiers.
10. Use the OUTPUT LEVEL adjustment to obtain the desired audio level.
11. The steps outlined in #8 may have to be repeated if you cannot get full power out of the amplifiers, in which case, start off with their input gain controls set for higher gain.
Note: Up to 10 amplifiers can be connected in this manner,
by also using MLX-100 outputs B thru E.

Noiseproblems

Hiss, orwhitenoise
1 - High levels of white noise usually occur when level controls are turned up too high - readjust according to the procedures in the
appropriateapplication section.
2 - Another major problem that can cause excessive hiss, is a noisy head unit - unplug the MLX-100 input RCA cables, and if the hiss level
reduces, thesourceunitis at fault.
Electricalinterference
The inside of an automobile is a very hostile electrical environment. The multitude of electrical systems, such as the ignition system,
alternator, fuel pumps, air conditioners, to mention just a few, create radiated electrical fields, as well as noise on the +12 volt supply and
ground. Remember to isolate the problem - first unplug MLX-100 input RCA cables, if the noise is still present, check the speaker leads, if
not, plugtheRCA’sback, andinvestigate the sourcedrivingtheMLX-100, onecomponentatatime.
