SMAKN® TPA3118 numeric 12V power amplifier board finished board /with switch potentiometer /Parallel Mono

SMAKN® TPA3118 numeric 12V power amplifier board finished board /with switch potentiometer /Parallel Mono
  • TPA3118 digital power amplifier board is to use the TI company TPA3118D2 high-performance power amplifier chip, beyond TPA3123 chips.DC power supply, wide working voltage 6-25v power supply, maximum 25W + 25W double sound channel output, support parallel bridge (PBTL) 50W mono output.
  • 1, this board design is practical based, small size (50x50mm), wide operating voltage (6-25V), output power (greater than 25W +25 W stereo), little heat, up to 90% efficiency, sound quality is also nice.2, most of the posts using the high stability SMD chip components, the performance is not comparable to ordinary hand into the material.
  • 3, sealed potentiometer with switch with power LED display, easier to use.
  • 4, with 3.5MM standard audio input jack; 3P socket can be fitted with 4, from "Lin" "G" "Rin" audio input, modification amplifier and more convenient.
  • 5, lower left corner of the board position reserved 5V/150-200mA power "Vout" output connector imports, which can be accessed within the decoding power 5V/180mA (default shipping without a 5V output). 6. Supports parallel bridge (PBTL) 50W mono output, speaker wiring: horn "+" then Lout (+) or (-), the speaker "-" then Rout (+) or (-), the other two pick imports blank.
The board size: 50 X 50 MM (not including potentiometer highlights 15 MM)
voltage range: 6-25V (power supply current is greater than 2A, power larger electric current is more than 3A)
Speaker impedance: 4 to 8 ohms
Maximum output power: 25W / 4o + 25W / 4o

Output power: (the speaker to choose suggestion: power less than 20V available, 4 to 8o greater than 20 v with eight o)
Tip: to the audio input enough, the power supply voltage/current under the condition of enough, will have enough power output.Power supply voltage higher relative power will be bigger, different speakers have different power output impedance.
Supply voltage: 12v -- 8o speakers (left sound channel) + 12w/ 12w (right sound channel), 4 the speaker/ >18 + 18w,
15v -- 18 + 18 8o/w, 4o / >22 + 22w,
19v -- 8o / 25 + 25 w, 4o / >28 + 28w,
22 and 24v -- 8o / >28 + 28w,
Parallel bridge mono output power: (mono speaker selection Suggestions: power less than 20v available 3-4o, >20v with 8o)
Supply voltage: 12v -- 3 the speaker / 30w, 4o / 25w,
15 v -- 3o / 43W, 4o/ >35W,
19 v -- 3o / >60w, 4 o/ >50w,
22 and 24v -- 8o/ >45w,
PBTL Model Connection Method:
1, Speaker: speaker positive connect Lout (-) ; speaker Negative connect Rout (-) ; The other 2 port empty without connection.
2, For S1-S6, default double channel : s1 connect, s2~s6 disconnect, so if you need PBTL model , you need put S1 disconnect, s2-s6 connect.(need welding tool)
3, If the improper operation burned the board, we are irresponsible, please understanding us. so please you careful to do.
