  • This is a Mixer Power Amplifiers control and mix up to eight independent input signals. The A-A-906MK2 delivers up to 60 watts of output power

    Optional plug-in modules are available for use with these mixer power amplifiers to provide versatility for a wide range of operating applications. Edge connectors on the rear of the unit permit the selection of the TOA plug-in modules.The mixer power amplifiers have output terminals to match 4- or 8-ohm speaker systems, or speaker distribution systems may be connected to 25- or 70-volt terminals, and can be rack mounted by using optional rack mounting bracket MB-25B. The optional perforated panel PF-511 provides suitable ventilation, finished in color to match the mixer power amplifiers.FEATURES
