FMOD COLOR CODE

 

High pass Fmods (filter modules) have red labels

 

Low pass Fmods have black labels

 

The color ring indicates Hlabs standard crossover frequency (-3db point)

There is an 8%(LP) / 25%(HP) frequency increase at 10K ohms and 8%(LP) / 15%(HP) frequency decrease at 47K ohm load. Otherwise all color design values of crossover frequencies are standardized at 22k ohms. Keep in mind that exact crossover frequencies are seldom noticed or necessary.

 

20hz  black bands (25hz @ 10K / 17hz @ 47K)

30hz  2 black bands (37hz @ 10K / 26hz @ 47K)

50hz brown band (54hz @ 10K / 46hz @ 47K) (62hz @ 10K / 43hz @ 47K)

70hz purple band (76hz @ 10K / 65hz @ 47K) (87hz @ 10K / 60hz @ 47K)

100hz has no band (108hz @ 10K / 92hz @ 47K) (125hz @ 10K / 85hz @ 47K)

150hz 2 blue bands (162hz @ 10K / 138hz @ 47K) (187hz @ 10K / 128hz @ 47K)

200hz blue band (216hz @ 10K / 184hz @ 47K) (250hz @ 10K / 170hz @ 47K)

300hz 2 white bands (375hz @ 10K / 255hz @ 47K)

500hz   white band (540hz @ 10K / 460hz @ 47K) (625hz @ 10K / 425hz @ 47K)

1000hz    light blue band (1080hz @ 10K / 920hz @ 47K) (1250hz @ 10K / 850hz @ 47K)

2500hz   light green band (2700hz @ 10K / 2300hz @ 47K) (3125hz @ 10K / 2125hz @ 47K)

3500hz   gray band (3780hz @ 10K / 3220hz @ 47K) (4375hz @ 10K / 2975hz @ 47K)

6500hz   orange band (7020hz @ 10K / 5980hz @ 47K) (8125hz @ 10K / 5525hz @ 47K)

 

Fmod Cables have the same color code but the direction determines the frequency. The color dot on the side where the wires connect to the amplifier shows the frequency. The black housing indicates low pass and the red housing indicates high pass.

 

Bass blockers have a dot on the red output cable.  

Color code for FMOD Cables ™

 

LOW PASS Black Label         HIGH PASS  Red Label

Two color dots for each Fmod Cable since dual crossover frequencies are available depending on direction of installation. See colors below.
