HF-SC2
2-CHANNEL SIGNAL CONVERTER
INTENDED USE
This device is only suitable for use in vehicles with a + 12V power supply and
negative ground. The device is used to convert the high-level signals from the
loudspeaker outputs of a head unit/car radio
into preamplifier signals (low-level signals) so that these can be used on
other audio devices such as amplifiers or processors.
INSTALLATION INSTRUCTIONS
To be on the safe side, disconnect the ground terminal of your vehicle battery
before installing the device in order to avoid short circuits and electric
shocks. Make sure that the device is securely
attached and that no important components of the vehicle are damaged during
installation.
When connecting, please ensure that all connections have the correct polarity!
EPS Protection Circuit
The high-level signal inputs are equipped with the “Error Protection System”
(EPS) so that no functions are impaired or error messages are written to the
vehicle memory when connected to OEM factory radios.
JUMPER FOR FLOATING GROUND
If you
unexpectedly hear interference from the alternator, you can disconnect the
connected ground of the vehicle from the pre-amplifier signal. To do this,
first, disconnect the power supply cable plug from the device and then
carefully open the housing using a suitable tool.
There is a small jumper inside the device at the bottom right. Carefully pull
out the jumper with a pair of pliers and insert it in the OFF position. This
creates a floating ground.
Then reassemble the housing and reconnect the device for operation.
