TOA Electronics A-9240SHM2CU 1 x 240W Digital Matrix Mixer

TOA Electronics A-9240SHM2CU 1 x 240W Digital Matrix Mixer

The A-9240SHM2 Amplifier is designed to be used in conjunction with optional modules and can be configured for up to 8 inputs and 8 outputs. 9000 series modules as well as existing 900 series input modules can be used. The most appropriate modules can be selected depending on applications. Since it comes with one 240 W power amplifier, it can individually perform multi-origin broadcasts. It is equipped with signal processing and control functions necessary for sound reinforcement, permitting all parameters to be set at the mixer. Settings data can be stored inside the unit and called up using the keys on the front panel.
