Item(s) Description/Condition:New in box. complete with bass knob

 

I am going to run 1 or 2 so this one is extra. It is the same as the ARC AUDIO KS500.1 mini but it was made for marine use. other than that same specs and same internal.

 

Robert Zeff is the engineer for ARC Audio. He is also the on the American team of engineers for UBUY which is a amp builder. He designs an amp and then its built by Ubuy overseas. The amp designs are also used for other manufacturers like Clarion, VIBE, ELF and KRYPT among others. same amps with slight variations. mainly cosmetic. many amps are made in same build house. nothing new about this practice.

 

what we have here is a variation of the ARC Audio mini ks500.1 . again same amp just different case and the crossover was moved to the side.

 

specs for ARC AUDIO KS500.1

ARC Audio KS 500.1 Mini

The KS 500.1 mini uses a Patent Pending Auto Sense Turn-on circuit that offers a significant improvement in reliability. No more will the amp unexpectedly turn off in the middle on a song. Instead of relaying on the music to supply enough signal to turn the amplifier on ARC Audio's new design detects the BTL IC (chip amp) used in the vast majority of stock head units and amplifiers. To further simplify OEM integration the KS 500.1 uses a fully balanced input stage that is switchblade between speaker and RCA input. Simply plugging your stock speaker wires into the RCAs will supply perfectly clean signal and turn the amp on. What could be easier then that? Well how about reversing the remote turn-on connection to turn on the rest of you amplifiers? Once the KS500.1 is set to Auto Sense the remote turn-on now becomes an output to turn on all your other equipment.
