Functions, inputs & outputs
1 - IN: Input of signal to be amplified. Connect the to the RCA output of the Head Unit using good
shielded cable to avoid noise interference.
2 - OUT: Audio signal output. Sends the same input (IN) signal to another amplifier, allowing cascading.
HIGH PASS FILTER (HPF): Variable setting from 10Hz to 90Hz, which determines the start of the
amplifier's operating frequency.
5 - BASS BOOST
BOOST: Set the boost level from 0 to + 10dB at the frequency set in FREQ.
6 - MONITOR: Accessory connection that has the function of monitoring the amplifier, displaying
clipping and protection status. (Included accessory).
3 - GAIN: Adjusts the input sensitivity of the amplifier, allowing a perfect adjustment to the output signal
levels of various head units models on the market. It is possible to adjust from 4V (minimum sensitivity) to
0.2V (maximum sensitivity).
4 - CROSSOVER
LOW PASS FILTER (LPF): Variable setting from 90Hz to 10KHz, which determines the end of the
amplifier's operating frequency.
FREQ.: Set the frequency of bass boost from 35Hz to 55Hz.
7 - SPEAKER: SPEAKER: Output (positive and negative) for connecting transducers (speakers). Follow
the indicated polarity.
For speaker associations, the impedance to consider is the resulting impedance:
