The latency (the time from which the DJM-900SRT is operated until the sound is output) can be shortened by lowering the buffer size setting. If there are interruptions in the sound, increase the buffer size, but note that this makes the latency longer. Set the buffer size to the minimum value at which no interruptions in the sound occur.

For Windows:

When using Serato DJ, click the [LAUNCH DRIVER PANEL] button of USB BUFFERSIZE(LATENCY) at [SETUP] > [AUDIO] and adjust the BUFFER SIZE on the [ASIO] tab of the Settings Utility.

When using Serato DJ, adjust USB BUFFERSIZE at [SETUP] > [AUDIO]. When using DJ software other than Serato DJ and when using an ASIO driver, adjust the buffer size at the [ASIO] tab of the Settings Utility. When using Direct Sound, adjust the buffer size from the DJ software.

For Mac OS:

When using Serato DJ, adjust USB BUFFER SIZE at [SETUP] > [AUDIO]. When using DJ software other than Serato DJ, adjust the buffer size from the DJ software.
