Panel Descriptions
7. USB indicator
This will light blue if the UA-25EX is connected to your computer via the USB cable and the
computer has correctly recognized the UA-25EX.
8. STEREO/MONO select switch (direct monitor section)
This selects whether the input signal from the combo input jacks (1) will be monitored in stereo
(STEREO) or in monaural (MONO).
If you’ve connected a guitar only to INPUT 2/R, set this to monaural ( pressed inward). Even if this
is set to monaural, the audio signal sent via USB to your computer will be stereo.
*If the digital input switch (6) is on, operating the STEREO/MONO select switch will not do
anything.
9. Direct monitor switch (direct monitor section)
This selects whether the input signal from the combo input jacks (1) will be output from the
headphone jack (13) and master output jacks (14). The direct monitor ON and OFF will change
whenever this switch is pushed. The direct monitor ON/OFF status can be controlled directly from
ASIO 2.0 compatible software such as Cubase.
*In digital input mode (p. 11), direct monitor is always ON, regardless of the direct monitor
switch operation.
10. Direct monitor volume (direct monitor section) knob
This adjusts the volume at which the input signal from the combo input jacks (1) is output from
the headphone jack (13) and master output jacks (14).
If this is turned all the way to the right, the monitored sound will be twice volume (+6 dB).
11. Direct monitor indicator (direct monitor section)
This will light when direct monitor is on, and will be unlit when it is OFF. If the digital input switch
(6) is turned on, direct monitor will be OFF automatically and the direct monitor indicator will be
extinguished.
12. Output volume knob
This adjusts the volume that is output from the headphone jack (13) and master output jacks
(14).
13. Headphone jack
Accepts connection of headphones. This jack will output the same sound as the master output
jacks (14). Sound will be output from the master output jacks even if headphones are connected.
Direct monitor switch Status
ON
(direct monitor indicator lit) The input signal will be output.
OFF
(direct monitor indicator unlit)
The input signal will not be output.
Use the OFF setting if the audio signal is being passed “through” within
the computer, or if you’ve connected a mixer and are monitoring the
input signal directly from the mixer’s output.
