Functions & inputs
3 - CROSSOVER:
Set the operating mode of amplifier :
1 - INPUT (RCA / AUTOMATIC REMOTE):
Inputs of signals to be amplified.
2 - GAIN:
It sets the amplifier input sensitivity, which allows an optimal adjustment to the
output signals levels of nearly all models of Head Units found in the market.
When using the AUTOMATIC REMOTE connection, check the + and - polarities of the RCA
cable with a multimeter to avoid possible cancellations.
For AUTOMATIC REMOTE connection:
To use this function, just connect the audio output
wires of the Players / multimedia to the RCA plugs. Note: When using this type of input
connection, all Rca’s cables must be connected and the gain adjustment must be in the 6V
position.
See illustration below:
For RCA connection:
Connect these signals to RCA outputs of Head Unit, using good quality
shielded cables to avoid noise interference.
SELECTOR POSITION - FULL
Amplifies the whole audio range, responding from 8Hz to
20KHz. This function is normally used when there is an
external crossover in the system.
Amplifies only bass signal, the response is limited to 90Hz
(-12dB/8ª), an optimal frequency cutoff for sub-woofers.
Amplifies signals with more intensity above 90Hz. This type
of function is used mid-bass, mid-range speakers or
tweeters.
