The Audison Connection SLI2.1 is a signal converter to convert from high to low level with a 4:1 ratio attenuation capability, designed to achieve input and output impedances that allow a perfect match between factory provided head units and any processors or amplifier installed in the system.
The SLI signal converters are equipped with the automatic turn-on device (ART, Automatic Remote Turn-on) to make up for a lack of remote signal, which is getting more and more common with OEM head units, to turn on/off the other system electronics.
For these interfaces the Connection designers especially developed an audio transformer equipped with a galvanic insulation system which keeps the grounds of the devices you have to connect separate in order to grant top level performances and very high disturbance rejection.
The windings precise arrangement and the material accurate selection for the core ensured a linear and extended frequency response even on the band extreme values, besides obtaining a correct output impedance, required to drive any device with pre-amplified level input.
