TOA TA-2030 PA amplifier, ideal for voice amplification with a microphone. - Brand: TOA - Model Name: TA-2030 - Type: PA Amplifier - Accessories: With microphone Thank you for viewing. It was used in a nursery school, but these devices are no longer needed due to a system change following the new construction and relocation of the school building. I will also include a TOA sound repeater (EV-20R). *Regarding the EV-20R, I have lost the power cable in the hustle and bustle of the move. There is no particular dirt as it was used indoors, but there are traces of sticker removal. It has been about six months since it was removed, and I can't confirm its operation now, but I think there should be no problem as it was used right before removal. In the unlikely event that the product does not work, please consult with me.
