HDESCRIPTION
9000ME SERIES AMPLIFIER
A—9120DHM2(CU)
The A—=9120DHM2 Amplifier is designed to be used in conjunction with optional modules and can be
configured for up to & 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 two 120 W power amplifiers, 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.
