Why is there excessive noise coming from my Toa A-9120DHM2?
Excessive noise in the Toa Amplifier can occur due to an incorrect module input sensitivity setting. The unit digitizes audio signals and varies the input level with a digital volume control. If the input or output volume control is set higher than 0 dB while the AD converter input remains low, noise may increase. Adjusting the input sensitivity setting can resolve this issue.
What to do if the sound from my Toa Amplifier is distorted?
Sound distortion in the Toa Amplifier is often due to an incorrect module input sensitivity setting. The unit digitizes audio signals, and if an extremely large input is fed into the AD converter, the sound remains distorted even when the volume is decreased. Adjusting the input sensitivity setting can resolve this issue.
Why is my Toa A-9120DHM2 Amplifier malfunctioning?
If your Toa Amplifier isn't working as expected, it might be due to an incorrect item or parameter setting. Review the related settings and their contents to ensure they are properly configured.
How to fix phantom power not working on Toa A-9120DHM2 Amplifier?
If phantom power is not being supplied by your Toa Amplifier, it could be due to a couple of reasons: 1. The D-001T module mounting screw might not be securely tightened. Make sure the screw is tightened. 2. The phantom power might be set to OFF in the D-001T module input setting. In this case, set the phantom power to ON in the input setting.
Why are the Zone manager and Remote control panel not working on my Toa Amplifier?
If the Zone manager and Remote control panel aren't working with your Toa Amplifier, check that the correct type of Zone manager or Remote control panel is selected and that the ID is set correctly. Also, a higher-priority broadcast might be in progress, indicated by the paging activation function SW flashing.
What to do if only some settings on my Toa A-9120DHM2 Amplifier are not working correctly?
If only some settings are not working correctly on your Toa Amplifier, it could be due to an incorrect module type being selected or a module being inserted into the wrong slot. Verify the related setting items and their contents.
Why is my condenser microphone not working correctly with my Toa A-9120DHM2?
If your condenser microphone isn't operating correctly with the Toa Amplifier, and it requires over +24 V, the D-001T module's phantom power supplies +24 V. You'll need to separately prepare phantom power supply equipment recommended by the equipment manufacturer.
Why is noise generated by my Toa A-9120DHM2?
Noise generation in your Toa Amplifier might be due to a module mounting screw that is not securely tightened. Ensure that the screw is tightened to resolve this issue.
