Pop/Click noise happens on a Mac.

Please check the following items:

• Open “Preferences” in the Options menu, click “Hardware” tab. Please increase the buffer size here. This will increase the latency but not by much.

• If other applications or programs are running, quit them all.

• Choose “Better Performance” at “Energy Saver” if you are using a laptop.
  1. Open “System Preferences”.
  2. Open “Energy Saver”.
  3. Click “Better Performance” at “Optimization”.

• Use the AC adapter if you are using a laptop.
• Disconnect wireless network e.g. wireless LAN and Bluetooth.
• Connect the JamVOX Monitor directly to a USB port on your Mac without using USB hubs.
• Disconnect other peripheral devices (e.g.printers) if possible.
