The Ihos QUADRO DSP 2.0 PA power amplifier combines an integrated DSP with the ability to monitor the amplifier’s status and remotely adjust its operation in real time. The DSP includes a noise gate, matrix mixer, parametric equalizer, crossover, delay and compressor. It is suitable for meeting and conference rooms, schools, restaurants and shopping centres.
