здравствуйте! Можно ли в устройство загрузить новые эффекты?
@Константин Zoom A1x four
Does the MAA-1 mic require the +48v setting to be engaged?
The Zoom A1 FOUR does not require the +48V setting for the MAA-1 mic unless a condenser mic or another device that requires phantom power is connected. Only set it to +48V if the connected mic needs phantom power.

Can a green "bullet" for harmonicas be connected directly to the A1Four without going through the MAA-1 microphone attachment?

How does one attach two different acoustic instruments to the A1 Four
The Zoom A1 Four is designed for use with one acoustic instrument at a time. It does not support connecting two different acoustic instruments simultaneously. To use a different instrument, you must disconnect the current one and connect the new instrument, then adjust the settings or patches accordingly.

Здравствуйте, у меня ZOOM A 1Four, я его использую для кларнета. Подскажите пожалуйста, как мне сделать так чтобы октавер на верхных нотах звучал громче и ярче чем на нижных нотах? Сейчас звучить на оборот на нижных нотах очень громко, а на верхных нотах почти не слышно.
To make higher notes sound louder and brighter than lower notes on the Zoom A1 Four, you can adjust the EQ and compression settings:
1. Use EQ: Boost the high frequencies and reduce the low frequencies to enhance brightness and emphasize higher notes.
2. Use Compression: Adjust compression to control dynamic range and reduce the difference between loud and soft notes, helping higher notes stand out more evenly.
These settings will help shape the tone to make higher notes more prominent.
