To Next PageTo Next PageWhy is there excessive noise in my Toa M-9000?
Excessive noise in your Toa Amplifier can be caused by an incorrect module input sensitivity setting. The unit digitizes audio signals with an AD converter and varies the input level with a digital volume control. Therefore, noise increases if the input or output volume control is set to a level higher than 0 dB while the AD converter input is kept low.
What to do if a condenser microphone does not operate correctly with Toa Amplifier?
If your condenser microphone isn't operating correctly with the Toa Amplifier, it might be because you're using a condenser microphone powered by over +24 V. The D-001T module's phantom power supplies +24 V. If using a condenser microphone powered by over +24 V, separately prepare phantom power supply equipment recommended by the equipment manufacturer.
Why is phantom power not supplied on my Toa M-9000?
If the phantom power is not being supplied by your Toa Amplifier, and you're using a D-001T module, it could be that the phantom power is set to OFF in the D-001T module input setting. To resolve this, set the phantom power to ON in the setting.
What to do if phantom power is not supplied on Toa Amplifier?
If the phantom power is not being supplied by your Toa Amplifier, and you're using a D-001T module, it could be due to the module mounting screw not being securely tightened. Ensure that the module mounting screw is tightened.
What to do if Toa M-9000 malfunctioned?
If your Toa Amplifier isn't operating as intended, it could be due to an incorrect item or parameter setting. Check the related setting items and their contents to resolve this.
