The Kara OK with original Pu-board (PTC brand) PT2399 are responsible for the echo sound processing， PT2399 is a genuine classic Kara OK echo processing integrated circuits on CD, VCD, DVD, TV sound noon, Kara OK machine wide range of applications .Using Texas Instruments (TI) of the latest high-speed low-noise FET TL074 quad op amp is responsible for the audio signal amplification and sound processing. PCB with high-grade double-sided fiberglass board, rational layout, nice, full of materials, SMT placement machine, stable performance!!

The karaoke OK board adopts two microphone inputs (compatible with electret microphone), two microphones by independent potentiometer control: avoiding the A singer voice sounds a lot to cover up B singer.

The main technical parameters:
1 .Supply voltage: input single power supply, optional AC or DC input, regardless of the positive and negative DC power supply can access. Input voltage range: AC 9V~12V, DC 12V~16V, 500ma supply current can be used (can be connected using a 12V battery-powered).
2. The board size: LxWxH=95x29x15mm (size excluding potentiometer handle protruding parts)
3. Potentiometer center distance: 20mm

The use of note:
1 .Carefully check before electricity, make sure the wiring is correct after only pass.
2. The circuit wiring as figure shows.
