Noise is heard during audio playback
In some cases, you may also be able to solve this problem by grounding the chassis of your
computer, or the grounding connector of the AC power supply plug of your computer. In addition,
you can check whether any devices that produce a strong magnetic field are located nearby, such
as a television or microwave oven.
• Are two or more audio devices such as the PCR-1 or a mixer connected to your
computer?
Try connecting only a single PCR-1 unit, and check whether the noise disappears. If numerous
audio devices are connected to a computer, noise may occur depending on your system. In such
cases, connect only the PCR-1 to your computer.
Does your sequencer software support ASIO 2.0 or 24-bit audio?
If your ASIO-compatible software does not support ASIO 2.0, it will not operate correctly if you use
[PCR-1 ASIO2.0 16bit] or [PCR-1 ASIO2.0 24bit] as the ASIO driver.
In this case, select either [PCR-1 ASIO1.0 16bit] or [PCR-1 ASIO1.0 24bit] as the ASIO driver.
If your ASIO-compatible software does not support 24-bit audio input/output, it will not operate
correctly if you select
[PCR-1 ASIO1.0 24bit] or [PCR-1 ASIO2.0 24bit] as the ASIO driver. In this
case, select either [PCR-1 ASIO1.0 16bit] or [PCR-1 ASIO2.0 16bit] as the ASIO driver.
