Title: Does Ultimarc's video amplifier protect arcade monitors from 31kHz sync?
Post by: tobiasbp on March 19, 2013, 08:22:01 pm

I have just purchased the Ultimarc video amplifier to connect at PC to my arcade monitor.

In the description of the video amplifier it says:
The circuitry is exactly the same as that used on the J-PAC and uses a high-bandwidth video amplifier chip..

In the description of the J-PAC it says:
If required, can divide a 31Khz VGA signal in half so that it will display a stable picture on a 15Khz arcade monitor. Useful for checking boot-up progress and configuration (not for application use). Automatically stops dividing the signal when it detects a correct 15Khz rate is being send by the PC.

So, is the video amplifier able to protect my monitor from potentially harmfull 31 Khz signals?

I think no. The same in the sense of the signal booster circuit.
