FAQ

General

If I am using low-impedance (Lo-Z) connections, can I connect the speakers to the MA/PA Series with an impedance of 2Ω?

The units do not support any 2Ω speaker systems.

Can I use a condensor microphone with the MA/PA Series?

Yes, you can use a condensor microphone with MA2120.
If you want to use a condensor microphone with MA2030a, you will need to supply power to the connected condensor microphone from an external power source.

How many VXC/VXS series speakers can I connect to the M/PA Series using high-impedance (Hi-Z) connections?

The table listed above indicates the maximum number of speakers that you can connect to each channel on the amplifier.
This number is specified to allow 20% of headroom for the rated output, and to prevent the total speaker impedance from falling below the minimum impedance of the amplifier.

You can connect the MA Series to the PA Series to increase the number of output channels and drive more speakers.

(Note)
The numbers in this table are recommended values. Yamaha is not responsible for problems caused by the information that appears in this table.
For more information on the detailed specifications, please refer to the specification chart on our website, or the latest user manual.

Are there any installation tips for the MA/PA Series?

Placing the device(s) on a table

This device has ventilation holes at the top bottom/sides to prevent the internal temperature from becoming too high.
Make sure that there is adequate space around the device: at least 10 cm above, 1 cm below the bottom surface (rubber feet provide adequate space), and 10 cm behind.

Installing on an EIA standard rack

If you are mounting the MA /PA Series along with other devices, be sure to keep 1U space above and below between the units and other devices. Also, keep the space between them well ventilated by installing a ventilation panel or leaving the space open.

Open the back panel of the rack and place the rack away from the walls and ceiling by more than 10cm to keep it well ventilated. If you have installed a fan kit on the rack, closing the back panel of the rack may be more effective for releasing the heat. For more information, please refer to the instruction manual for the rack or fan kit.

If the MA Series and PA Series are connected, which settings can I control individually?

You can control the Output Volume,Speaker EQ settings,and Output EQ* individually. Use the DIP switch on the rear panel to set the Speaker EQ. (For information on setting the Speaker EQ, refer to the User Manual or the Setting Guide Label on the top panel of the device.)
*Only MA2120 and PA2120

The DIP switch setting for SETUP seems to be ineffective.

The setting will be active when the power is turned on. Turn off the power, and then turn it on again.

Do the MA/PA Series feature any protective functions?

The MA/PA Series monitor the voltage, current, and temperature at the power source section and amplifier section. If each of the amplifier units gets overloaded or over heated, it will lower the output or mute temporarily, depending on the situation, to prevent the amplifier unit, speakers, and other connected devices from being damaged.

How is the volume control of the MA/PA Series related to the volume control of the DCP Series?

You can control the volume of the MA and PA Series, and the volume of the DCP Series independently. However, the volume level set for MA and PA Series, will be effective over the DCP Series volume control. Therefore, if the volume of either DCP Series or MA/PA Series is not raised when DCP Series is connected, no sound will be output. Refer to the figure below for information on how the volume controls work between the MA/PA Series and DCP Series.
