SGN-121
55watt per Channel High Power Line Output Converter
Don’t cheat yourself out of all the performance your new radio or amplier can deliver. Proper audio line level
matching is critical when replacing your vehicle’s factory (OEM) radio or amplier. It can be the difference
between a great sounding system that you enjoy every day and a buggy, noisy mess that drives you crazy.
Stinger™ interfaces have been professionally designed for those who want the very best.
The SGN-121 can be used for adding ampliers to a system that does not have RCA outputs. The output level
is xed and level matching is achieved using the gain dials on the amplier. High quality audio transformers are
used to allow for the best possible audio quality and noise free signal to be passed to the new amplier. Input
signal to the SGN-121 is good for 55 watts per channel.
Speaker level input to RCA level output is the most commonly used conguration for the SGN-121.
Use this when you need to create RCA level outputs from a source that only has speaker level outputs.

Left/Right Audio Inputs: Connect to source unit speaker wire(s) making sure to match the polarity (+/-). The black
stripe is Negative(-). If you are adding an amp to power additional speakers or a subwoofer, then you’ll just "tap" into
the speaker wires to pick up the audio signal, and the existing speakers will continue to play audio. If adding a sub-
woofer and need only a Mono signal, join the Left & Right Negatives and Left & Right Positives on one speaker.
Audio Ground Output: The Brown wires are optional and should not be connected initially. If there is audio noise,
ground one or both of the Brown wires to eliminate minor noise.
