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.

Is a mic or guitar still connected?
If a mic or guitar is connected to the PCR-A30, disconnect the mic or guitar, and turn the
Gain knob
all the way
to the left.Disconnect any audio devices you are not using.
•
Are two or more audio devices such as the PCR-A30 or a mixer connected to your computer?
Try connecting only a single PCR-A30 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-
A30 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-A
ASIO2.0 16bit]
or
[PCR-A ASIO2.0 24bit]
as the ASIO driver.
In this case, select either
[PCR-A ASIO1.0 16bit]
or
[PCR-A 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-A ASIO1.0 24bit]
or
[PCR-A ASIO2.0 24bit]
as the ASIO driver. In this case, select either
[PCR-A
ASIO1.0 16bit]
