SLI 2 and SLI 4 are two signal converters 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.
SLI 2 and SLI 4, for 2 and 4 channels respectively, are equipped with 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.
The Connection creativity is not limited to technical design, it astonishes for its cosmetic design too. Hi-tech lines and refined materials make SLI’s perfect. The heat sink is in die-cast aluminum and the protective case is of translucid scratchproof black polycarbonate. SLI 2 and SLI 4 complement the Connection product range offering two high quality interfaces that allow any car hi-fi fan to upgrade their factory system.
