The DA series of professional power amplifiers are Class D installation amplifiers. It is suitable for two types of 70/100V line installations (optional via DIP switches). Each channel has volume control and LED indicators (signal, clipping and protection).
The DA series of professional power amplifiers are Class D installation amplifiers. It is suitable for two types of 70/100V line installations (optional via DIP switches). Each channel has volume control and LED indicators (signal, clipping and protection). Input and output connections are made through European-style terminal blocks. Its 1U chassis height and 19-inch size are very suitable for many types of installations, and it utilizes a multi-channel design.
