main monitor output plays the final mix, or copies the
talent mix by selecting USB 9&10.
• Soft key. Here the function of the bottom button in the
main screen can be selected. You can choose between:
2nd out
(switch to 2nd speaker output);
special
(enable
the selected ‘special’ function from menu F1, like mono
or side);
dim 20 dB
(attenuate the output by 20 dB);
compare mode
(enable the compare mode of menu F2);
fast 0 dB
(set the volume level to the current reference
level).
• Phones phase. This flips the polarity of the
headphones output. Since there is no official standard
for the relationship between the electrical signal polarity
and the acoustical pressure polarity of headphones, a
positive going electric pulse can result in a pressure
increase on some brands’ headphones and a pressure
decrease on others. The UC1 polarity switch can be
used to achieve a positive polarity with your
microphone / headphones combination so that an
increase in pressure in front of your microphone will
result in an increase in pressure inside your
headphones.
This option can improve voice foldback monitoring
sound quality when using the UC1 with a microphone
and mic preamplifier. Since headphones always show
some leakage from environmental sounds, selecting the
right polarity will improve the coherence of the leaked
acoustic sound of your voice with the folded back
electric sound. This usually results in a warmer and
more pleasant sound experience when singing or
speaking. You can find the optimal polarity by talking
into your mic with headphones on and foldback
engaged, and then switching between normal and
inverted phase. Select the version that has most
subjective bass.
• Ref level. When this line is selected, a press on the
main dial stores the current volume level as the ‘0 dB’
reference playback level. The default setting is -8 dB,
which means that the UC1 monitor output has 8 dB of
gain available above the reference setting. If you need
more or less ‘excess gain’, you may change it here.
