Product Description

Board size: 66 * 55 * 23.5mm (L * W * H) (not including the potentiometer protruding part 15mm),
Operating voltage range: DC DC 12-24V (12-19V/ 2-3A above, if the power bigger 19-24V / 3-4A )
Audio input sensitivity: two-channel 700mV, associated mono 800mV.
Speaker impedance: two-channel speaker: 4-8Ω, associated mono speaker impedance: 3-4Ω,
Output power: 30W (left channel) + 30W (right channel) Dual channel, associated mono 50W
Two-channel output power:
12V / 10 + 10W (8Ω) / 15 + 15W (4Ω),
15V / 13 + 13W (8Ω) / 22 + 22W (4Ω),
19V / 20 + 20W (8Ω) / 25 + 25W (4Ω),
24V / 30 + 30W (8Ω), Two-channel speaker selection recommendations: power less than 20V with 4-8Ω, greater than 20V with 8Ω.

Associated mono output power:
12V / 18W (4Ω) / 22W (3Ω),
15V /> 25W (4Ω) / 35W (3Ω),
19V /> 40W (4Ω) / 50W (3Ω),
24V /> 30W (8Ω) / 50W (4Ω),
And then mono speaker selection recommendations: power less than 20V with 3-4Ω, greater than 20V with 8Ω.
Note:
The output power is related to the power supply voltage, the speaker impedance and the source input. Usually higher power supply voltage, can support the output power will be larger. Different impedance horn, can support the output power is also different.
