Computer USB Connector: Connect to the computer after successful software installation.
This is how CORE-1 communicates with your computer. Make sure that you have successfully
installed CORE-1 software, only then, you should proceed connecting the CORE-1 unit to the
computer using the supplied USB cable.
Bluetooth Audio Connector: Insert the provided Bluetooth Audio module. By utilizing the
supplied Bluetooth Audio module, you will be able to stream high-quality audio directly to CORE-1 by
pairing it with your cellphone. Make sure that the Bluetooth is enabled on your phone. Search for
Devices and you will find CORE-1. If not successful, please refer to the Troubleshooting item 13.
Bluetooth Audio Volume: Begin by setting it to the middle. This volume control is meant to
help you balance the volume of your Bluetooth audio device with your Head-Unit. Although CORE-1
comes with the volume set at the maximum level, we strongly recommend that you set the volume at
the middle and then, proceed making small adjustments to satisfy your listening preference.
RCA Audio Inputs: Connect to the audio output of your head unit, which can be either a
factory or an aftermarket model. These inputs are also compatible with Low Level audio, which you
should use with good quality RCA cables, as well as compatible with High Level audio, which you
should use the supplied “RCA to High Level” adapter cables. The inputs are “summed”, which
guarantees perfect compatibility with factory head-units by combining the frequencies of each
channel, resulting in the reconstitution of the full-range audio that will be further processed by the
CORE-1.
In case you’re using Low Level (or line level), make sure that you connect at least one pair (Left /
Right) of RCA cables from the RCA Outputs of your Head-Unit to the RCA Inputs of CORE-1.
In case you’re using High Level (or speaker level), use the supplied “RCA to High Level” adapter
cables to connect CORE-1 to the speaker wires of your head-unit. Please make sure to properly
match the phase (+/ -) and sides (left / right) in order to have a good listening experience. We
recommend to place the supplied “Dummy load” resistors across the (+) and (-) wires of the head
unit speaker output, basically “taking place” of the speaker that was originally installed. Please
consult the “Wiring Diagram” here. Some cars need this to “trick” the Head Unit into thinking that
the speaker is still present, thus allowing music to be played through the speaker wires. Equally
important, please do not use the REMOTE input of the Power source connector. The CORE-
1 features “AUTO-REMOTE”, which exempts the use of the REMOTE wire because it senses
when the factory head-unit has been turned ON or OFF.
