Introduction
Parts of the UA-30 and their function
fig.01-08
Line input jacks
Connect these jacks when you wish to record audio signals from an audio
device or MIDI sound module.
Line output jacks
Connect these jacks to the AUX IN or LINE IN of your audio system (amp or stereo).
Digital input connector (optical)
When inputting a digital audio signal from an audio device such as a CD/
MD/DAT, use an optical cable to make connections here.
Digital output connector (optical)
When outputting a digital audio signal to a digital recorder such as an MD/
DAT, use an optical cable to make connections here.
Digital input connector (coaxial)
When inputting a digital audio signal from an audio device such as a CD/
MD/DAT, use a coaxial cable to make connections here.
Digital output connector (coaxial)
When outputting a digital audio signal to a digital recorder such as an MD/
DAT, use a coaxial cable to make connections here.
USB connector
Use a USB cable to connect this to your computer so that audio data can be
transferred.

Before changing the
position of the Sample
rate select switch or the
Recording input select
switch, you must exit all
applications including the
UA-30 D-Out Smoother
(p. 37). You should also
turn down the volume of
any audio amp system
that is connected.
Sample rate
When audio is recorded
digitally, the level of the
sound is measured at
fixed intervals of time,
and the level is converted
into digital data. The
sample rate (sampling
frequency) is what
determines this time
interval. CD and MD use
a sampling frequency of
44.1 kHz, and DAT can
also use a sampling
frequency of 48 kHz. By
setting this switch to
match the sampling rate
of the connected device,
you can digitally record
without diminishing the
audio quality.
