6 2. SAFETY PRECAUTIONS • Before installation or use, be sure to carefully read all the instructions in this section for correct and safe operation. • Be sure to follow all the precautionary instructions in this section, which contain important warnings and/or cautions regarding safety.
7 When Installing the Unit • Never plug in nor remove the power supply plug with wet hands, as doing so may cause electric shock. • When unplugging the power supply cord, be sure to grasp the power supply plug; never pull on the cord itself. Operating the unit with a damaged power supply cord may cause a fire or electric shock.
8 3. GENERAL DESCRIPTION TOA's M-9000 Matrix Mixer is designed to be used in conjunction with optional modules and can be configured for up to 8 inputs and 8 outputs.
Important Be sure to disconnect the power supply plug from the AC outlet when changing the mode. Since the changes in mode will erase all setting contents, download the set files that need to be stored using the supplied PC software.
10 5.2. Glossary • Ducker function The Ducker function automatically attenuates input signals with lower priority when two or more audio signals are simultaneously received. This function cannot be used if any of such received inputs is not set for the Ducker function.
11 6. INST ALLA TION PRECAUTIONS • Keep the A-9060DH and A-9120DH amplifiers over 10 cm away from objects that may obstruct air flow to prevent the unit's internal temperature rise.
