Step 2: Controls
(EN)
(1) The GAIN control allows you to control
the gain from +26 to +60 dB to the
input signal. This control should be set
all the way to the left when connecting
or disconnecting a sound source from
the MIC500USB. When all connections
are made, slowly start raising the
gain control.
(2) We recommend using the LED meter
to help adjust the gain. The LED chain
displays the signal level of input channel
1/L after processing, in dB.
(3) Please make sure that the CLIP LED
never lights up continuously. It should
light up only at peak signals, but it
should never be on all the time.
(4) The 20 dB PAD switch reduces the
input sensitivity of input channel
1/L by 20 dB (switch pressed).
The appropriate setting depends on
the equipment connected. No matter
what your application is, the clip LED
warns you to reduce the gain setting to
avoid distortion.
Quick Start Guide
(5) This +48 V switch activates the
phantom power supply for the XLR
input. Phantom power supply is
required for operating condenser
microphones. Dynamic microphones
require no phantom power. Read and
follow the recommendations of your
microphone manufacturer, as some
microphones can be damaged by
phantom power.
(6) Press the LOW CUT switch to eliminate
undesired subsonic noise, such as floor
rumble, from input channel 1/L.
(7) The PHASE REVERSE switch reverses
the input 1/L signal phase by 180°.
It only affects IN 1/L (MIC or Hi-Z)
signals, not IN 2/R LINE. Use this
function in a multi-microphone setup
if you detect phase cancellations in
specific frequency bands.
(8) The OUTPUT control governs the
PHONES output level within a range
from -∞ to +10 dB. If the control is
turned all the way to the left, there is
no output signal at all. The more the
control is turned to the right, the higher
the output level.
