The board uses high power amplifier chip.
Power input connections: Can match socket or switching power supply DC input audio Socket.
Audio input connections: Standard 3.5mm audio input socket, or from 3pin input audio socket.
Supports high voltage 25V power supply, support parallel bridge 100W Mono Output, Supports with low impedance of the speaker, can be used with most speakers on the market.
Especially suitable for your demanding.
Tip: To the audio input enough, the power supply voltage / current under the condition of enough, will have enough power output. Power supply voltage is higher, and the relative power will be bigger, different speakers have different output power and output impedance. In enough voltage current situation, the speakers’ number is larger, the smaller relativity sound power, please note.
Double-track Output Power:
12V / 10 + 10W (8ohm) / 15 + 12W(4ohm)
15V / 13 + 13W (8ohm) / 25 + 22W(4ohm)
19V / 22 + 13W (8ohm) / >39 + 39W(4ohm)
22 ~ 24V / >32 + 32W (8ohm) / > 50 + 50W(4ohm)
Parallel Bridge Mono Output Power:
12V / 18W (4ohm) / >22W (3ohm) / >30W (2ohm) 15V / 27W (4ohm) / >35W (3ohm) / >48W (2ohm)
19V / 45W(4ohm) / >55W (3ohm) / >75W (2ohm)
24V / >70W (4ohm) / >95W (2 ~ 3 ohm)
Operation Voltage: DC 9-25V (Power supply current is greater than 3A. If you need larger power, we suggest that the Operation Voltage is 19 ~ 24V, and the current is 4A or Above).
(Note: The voltage is not greater than 25V)
Speaker impedances: 3.5 ~ 8ohm (Double-track Speaker), 2 ~ 4 ohm (Parallel Bridge Mono Speaker).
Maximum Output Power:
Double-track: 50W (left track) ~ 50W (Right Track)
Parallel Bridge Mono: 100W
Audio Input connector: Standard 3.5mm or 3pin audio input jack.
Audio Input sensitivity: Double-track: 600mV; Correlation Single-track: 750mV
