Parameters:
Working current: 8-25V
Power: 0-50W (Left +Right)
Outer diameter of power connector: 5MM
Inner core of power connector: 2.1MM
Size: 91*36*108mm

Description:
1. Power supply: The power supply should be with small power ripple and the power voltage can be 12-24V. (If in low voltage, the output power will be also in low display, finally the speaker will be in low voice.)
2. Signal Wire needs shield layer to avoid interrupting small signal for balanced input and output signal to maintain a high-quality sound.
3. The HIFI speaker can be connected with mobile phone and computer, but the quality of voice will be based on the signal source or the signal wire.
 
Note:
1. This HIFI do not have a direct power supply for power and can be connected with the notebook for power, but with plug for 5.5*2.5mm.
2. Must be first well-connected the power port and the HIFI power port and then power on the power supply of the computer or notebook.

Package Includes:
1 X Digital Amplifier

Product Features

  • This DROK 50W+50W dual-channel power amplifier will be powered by DC 8~25V. It has 90% high efficiency and lower internal resistance because we used of import seal potentiometer and high speed capacitor array. It can use power switch, storage battery, vehicle power, and so on.
  • Adopted TPA3116D2 amplifier chip as core; Germany VIMA MKP10 as input capacitor makes harmonic richer; the top red loop outputs inductor makes its voice purer; Aluminum alloy body is easy to heat-sink; Gilding RAC and crystal terminal looks extravagant.
  • Power supply: The power supply should be with small power ripple and the power voltage can be 12-24V. (If in low voltage, the output power will be also in low display, finally the speaker will be in low voice.)
  • Signal Wire: Signal Wire use to transit weak small signal. And our signal wires have shield layer to protect signal from other unstable factors.
  • The HIFI speaker can be connected with mobile phone and computer, but the quality of voice will be based on the signal source or the signal wire.

An inexpensive compact amplifier does the job I was looking for an amp for a raspberry pi 3 media center (OSMC) for my patio. I decided to try the Drok based on reviews and homebrew project reviews based on the TI amp chip this unit utilizes. Having to find a separate power supply is a pain but since I had an old 20v 4.5 amp laptop supply I didn’t have any additional expense in this case. So far I am very impressed with the dBSPL I can deliver driving a pair of OSD 7in 8 ohm patio speakers. Filling the whole back yard with sound with a…
