Three main factors can cause this and there are three possible countermeasures:

■When buffer size is the cause

If the buffer size is too low, sound cutting or noise may occur.

You can adjust buffer size in rekordbox [Preferences] < [Audio] < [Buffer size].

(Windows users can adjust it in [Preferences] < [Audio] < [Setting Utility] < [ASIO tab].)

First, select a large value such as 1024. If the problem clears up, adjust to a value small enough that you don't experience a delay in operation (latency).

*The appropriate value depends on the system specification.

■When the connection or other equipment is the cause

An unstable connection with your PC/Mac might cause these problems.

To solve this, shut down your PC/Mac and disconnect all other USB devices and USB hubs. Then, connect the OPUS-QUAD directly to a different USB port.

■When your system (PC/Mac) is the cause

Doing the following might solve the issue:

- Quit all other applications.

- Disconnect from the internet and exit security software.

- Turn off wireless connections such as Wi-Fi or Bluetooth.

- Turn off power-saving settings.

If your computer's system doesn’t meet the requirements of rekordbox, it might cause the issue. See details on system requirements [rekordbox.com].
