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.
