Audio Electronics, KA2281 STEREO WITH 520 LED VU METER CIRCUIT subject " ka2281 volume control * * * vi * vu meter meter "tagged with
Amplifier circuit in the output volume I made a circuit to observe the LEDs "vu-meters" We know our circuit the most
An old project I put a simple LED circuit As They die of a perforated plate in 2004, but the is before I painted with black spray paint plaque was better and the view was to Contribute to the brightness of the LEDs in the
if you can connect the 220V LED lamps can USED trafoya do not need to supply the triac BT139 triac or TIC206 or a sound Suitable Providing power to the load can depend on any device ( PC mp3 mp4 player dvd vcd )
Should be Higher coal audio signal if you want to connect to is not connected to the amplifier output directly shouldnt Increase the value of r14 and r14 VU-Meter Circuit of control integrated in KA2281 MOC3010 opto-isolated outputs are Kubla with 12 volt DC integrated circuit feed voltej LEDs for 50w 28V AC voltage transformer was Awarded the rectification was without USED
Asks forwarded 10 LEDs integrated mono stereo 5 + 5 LED circuit can be as stereoisomeric I USED USED green 5mm LEDs per channel in 52 red LEDs connected in series parallel connection Consists of two parallel center Directly connected to the integrated LEDs
The original version of the VU Meter circuit
The modified circuit
Led series parallel connection
