My sound system has excessive “HISS” noise:
SOLUTION:
Make sure that the GAIN of your power amplifiers are set to the minimum
, in other words, fully
turned counter-clockwise. CORE-1 is a high output Line Driver
that works as a “pre-amplifier”, for this
reason, the gain setting of the power amplifiers should be set to the absolute minimum because the pre-
amplification is already being accomplished by the CORE-1 unit.
Always prefer to increase the gain on
CORE-1 software, rather than on your power amplifiers.
If the hiss continues to happen, try reducing the Gain levels using the CORE-1 software. For best noise
optimization, the Gain should be set to the minimum possible level that still statisfies your desired level of
Sound Pressure.

) My sound system makes “POP” or “THUMP” noise
as CORE-1 is powered ON / OFF.
SOLUTION:
Make sure that the Remote inputs of the Amplifiers are connected to the Remote Outputs of
CORE-1 rather than directly to the head unit.
The CORE-1 manages the remote of the amplifiers so they
are powered ON / OFF in the correct sequence along with CORE-1 in order to guarantee completely noise
free operation.
Make sure that CORE-1 is connected directly to the fully charged 12 Volt
vehicle’s battery,
without any sort of switch.
CORE-1 has its own Power-ON and Power-OFF sequence that needs to be
respected at all costs in order to ensure proper operation, free from noise, and no memory corruption.
Therefore, it is of extreme importance that CORE-1 is provided with a constant and steady power source.
9) I am using High-Level input with my factory Head-
Unit, however, no sound comes out.
SOLUTION:
Make sure that you have resistors connected across the speaker output wires of the head-unit.
Some cars can “sense” if the speaker is connected to the head-unit or abscent. For this reason, “dummy
load” resistors are provided in order to “trick” the head-unit into “thinking” that the speaker is present, thus
allowing for audio output.
