Захранващо напрежение: DC5V-34V, 4-8 ома.
Размер: 75 * 50 * 20 мм

Specification:


Working voltage: DC 5v-34v

Maximum output power: 130w

Chip: CS8683 high-power digital power amplifier chip

Standby control description:

SD
is the standby control terminal, low-level mute, high-level work (the
control voltage can be from 3v-35v), the default is the working state
when delivered, when the standby control is required, the R1 resistor on
the board needs to be removed, and the external control will do .

Gain
setting terminal description: The default floating state gain is 40
times. If a higher gain is required, just short-circuit the two pin
interfaces of the gain setting terminal, and the gain after
short-circuiting is 54 times.

The signal input mode can be selected from the following two according to your needs:

1: Signal Balance Input (Differential): Signal+, Signal-,

2:
Unbalanced input (single-ended): the - terminal is short-circuited with
GND (ground), and the signal is input from the + terminal.

Note:
When the input is unbalanced, be sure to short-circuit the "-" with
GND, otherwise the sound will be abnormal, and the chip may be burnt out
in serious cases.
