MAXX-LINK MLX-100

UNIVERSAL AMPLIFIER BRIDGING & SYNCHRONIZATION MODULE

The MLX-100 Maxx-Link is a unique problem solving signal processor. The Maxx-Link

allows interconnecting (a.k.a. Linking) of up to five amplifier pairs in Master/Slave

configurations to a single subwoofer or multiple subwoofers. This is an incredible

solution for expanding your system and allowing for linking of non linkable mono block

amplifiers.

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. BYBASS: BR-1 is set to 0dB fixed regardless of where the dial is set.

LINE INPUT: Accepts unbalanced RCA inputs from 0.2 volts to 9 volts. LINE OUTPUT: The unbalanced RCA outputs are Left and Right Full Range outputs. BRIDGING OUTPUTS: A+/- through E+/- provide signal output to up to 10 linked mono

block amplifiers.

TOP MOUNT CONTROLS

MASTER/ SLAVE MODE: Should be set in Master position when controlling amplifiers

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 Volts AC.

- Connect the positive Voltmeter lead to the (+)POSITIVE SPEAKER TERMINAL on amplifier #1.

- Connect the negative Voltmeter lead to the (-)NEGATIVE SPEAKER TERMINAL on 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.

TROUBLESHOOTING A SYSTEM

The key to finding the problem in a troubled sound system is to isolate parts of that system in a logical fashion to track down the fault.

Description of the Diagnostic system built into the MLX-100 Maxx-Link Bridging Module:

1. Clipping Indicator: Red Illumination when signal is clipped.

2. Normal Operation: Green Illumination, when signal is unclipped up to 9volts.

The diagnostic system will not shut down the MLX-100 or the amplifier(s), although the amplifier(s) own protection circuitry may shut the

amplifier(s) down should a fault status occur. At which time you will need to consult the owners manual for that particular amplifier.

Low output power

1 - Check that level controls have been set up properly.

2 - Make sure that the battery voltage, as measured at the amplifier’s and MLX-100’s +12 volt and ground terminals, is 11 volts or more.

3 - Check all +12 volt and ground connections.

Fuses blowing

1 - Insure that the voltage to the unit does not exceed 15 volts.

2 - A short on the main +12 volt cable from the battery to the vehicle chassis will cause the main fuse to blow.

3 - If the MLX-100 is blowing fuses continually with only +12 volt, ground and remote leads connected, the unit may be faulty.

System does not turn on

1 - Check all fuses.

2 - Check all connections.

3 - Measure the +12 volt and remote turn on voltages at the amplifier and MLX-100 terminals. If these are non existent or low, take

voltage measurements at fuse holders, distribution blocks, the head unit’s +12 volt and remote leads to localize the problem.

Noise problems

System noise can be divided into two categories, hiss, and electrical interference.

Hiss, or white noise

1 - High levels of white noise usually occur when level controls are turned up too high - readjust according to the procedures in the

appropriate application 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, the source unit is at fault.

Electrical interference

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, plug the RCA’s back, and investigate the source driving the MLX-100, one component at a time.

A ticking or whine that changes with engine RPM:

1 - This problem could be caused by radiation pickup of RCA cables that are too close to a fuel pump or a distributor.

2 - Check that the head unit ground is connected straight to the vehicle chassis, and does not use factory wiring for ground.

3 - Try to supply the head unit with a clean +12 volt supply directly from the battery +, instead of using a supply from the in dash

wiring/fusebox.

A constant whine:

This type of noise can be more difficult to pinpoint, but is usually caused by some kind of instability, causing oscillations in the system.

1 - Check all connections, especially for good grounds.

2 - Make sure that no speaker leads are shorting to exposed metal on the vehicle chassis.

3 - RCA cables are notorious for their problematic nature, so check that these are good, in particular the shield connections.
