    I would love to know why the design engineers of all 3 main prods mentioned (Krypt, ZLD, WS420) went and put the gain adjustments on top of the units rather than on the bottom. Making any adjustments after install is a royal PITA because of the mounting bracketry wizardry that has to come apart in order to drop the thing down and access the adjustments. It's easier for me to climb into my compartment to adjust the amps than in it is to drop down the EQ to adjust gains.

    Why not put those on the bottom instead?





    Old enough to know better, young enough to do it anyway.

    David,

    Knowing that the noise is present when the engine and blower are running is good info. In my experience, most calls I get or boats that come in with a hum/hise type noise when the engine is running and have a dual battery bank, almost always leads back to where the head-unit/source unit, obtain their B+. Its usually battery A and the amps are drawing from battery B. Other cases, theres an EQ or similar that may have its B+ run to the same battery as the amps, but its GND is grounded to the helm BUSS. Even though the boats entire ground plane goes back the battery bank and engine block, we sometimes find the need to relocate that EQ ground over directly to the battery and an amp's GND lug. Next up would be the gains, whether its and EQ or an amp, if they are too high, normal noise in the system can be amplified to a point of being audible.

    I would start there, then we can did deeper if needed.

    Thats a first gen WS-420. havent seen one in about 4 years. The gains are fixed (set at the factory) and no holes exist now.

    If the krypt sounds fine I wouldn't not spend the 299 on ws, if its gone bad then sure thing.

    Berg,
    As MLA noted, that was the first gen WS EQ. Wetsounds provided rubber inserts to seal the holes but after owners used the gains they often did not re-install the inserts. This became the number one entry point for water. So Wetsounds eliminated the externally available option. While they fixed that they introduced protected switches on the face and cured another corrosion issue. There are numerous other revisions and refinements that followed.
    This is a single sided circuit board (all components on the top side) with limited real estate and very dense coverage so if you are going to include adjustments they must be topside, on the back panel or front panel. Underneath is not an option.

    David,
    MLA is correct in his assessment of your noise.
    I can give you a sequential step-by-step presciption to isolate and confirm the noise source. Once you isolate the cause the fix is a walk in the park. No more specualtion. Noise is gone.
    David
