Driver installation and settings (Macintosh)
You must install the UA-25 driver even if you will be
using only audio on the UA-25. Be sure to install the
UA-25 driver before you install the ASIO driver. (p. 36)
This section explains how to install the ASIO driver that
allows the UA-25 to be used by your sequencer software or
audio editing software.
For details on installation and settings of the ASIO driver,
be sure to also read the
Driver E (Mac OS 9) -
Readme_E.htm document on the CD-ROM.
The ASIO driver of the UA-25 supports the following audio
input/output channels.
• Audio input....... 24/16 bit 1 stereo ch. (2 monaural chs.)
• Audio output .... 24/16 bit 1 stereo ch. (2 monaural chs.)
If your ASIO-compatible software supports ASIO 2.0 or
recording/playback of 24 bit audio data, using the
following drivers will provide a higher quality
environment.
Here we will explain how to install the ASIO 1.0 16 bit-
compatible driver.

ASIO
This is an audio interface
standard promoted by the
Steinberg Corporation. When
the UA-25 is used with ASIO-
compatible software, the
synchronization precision will
be improved, allowing a more
sophisticated music
production environment.
The UA-25 cannot play back audio data from the
Macintosh’s sound manager (such as audio CDs
and alert sounds).
