TUBE ULTRAGAIN MIC500USB Controls
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.
(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 fl oor
rumble, from input channel 1/L.
(7) The PHASE REVERSE switch reverses
the input 1/L signal phase by 180°.
It only aff ects 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
specifi c 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.
(9) The PREAMP MODE rotary switch gives
you a wide selection of preamp presets
for input channel 1/L signals. 16 presets
with diff erent sound color from WARM
over LIMITER to NEUTRAL are available.
(10)
The DIRECT MONITOR switch allows you
to monitor in headphones a mono mix
of input channel 1/L and 2/R, merged
with the stereo playback coming from
USB. Set the OUTPUT control to minimum
before putting on the headphones,
27 Quick Start Guide
and then adjust as required. If the switch
is not selected, then the headphones
will play only the audio playback from a
computer, via the USB connection. If no
USB is connected (or no audio application
running), you need to press the DIRECT
MONITOR switch to listen to the analog
inputs (stand alone mode).
(11) Use the POWER SUPPLY CONNECTOR
to hook up the enclosed power
supply unit.
(12)
Connect to the USB port of a computer.
The device is class-compliant and no
drivers are required. However you can
use a 3rd party ASIO driver (ASIO4ALL)
to reduce audio latency while live
recording on your computer. Set your
digital audio workstation (DAW) to
recognize the device as an audio input
and output. Two channels of audio can
be sent to the computer: One channel is
the signal from the MIC or IN 1/L (after all
the controls, gain, modes, and the tube
section). The other channel is the input
signal from IN 2/R (LINE). Two channels
of audio can be received from a computer
and monitored on the PHONES output
(independent of the position of the
DIRECT MONITOR switch).
(13)
The PHONES output allows you to
listen to the stereo signal from a
computer, and (if the DIRECT MONITOR
switch is on) listen to a mono mix of
input channels 1/L and 2/R. Set the
OUTPUT control to minimum before
putting on the headphones, and then
adjust as required.
(14)
The balanced ¼" TRS DIRECT OUTPUT
can be connected to a mixer, recording
system or power amp. This is the
line-level output of the IN 1/L (MIC or
Hi-Z) audio signals after having passed
through the preamplifi er and tube
section. The output contains no audio
from IN 2/R LINE, or from the computer.
(15)
Ideally, the balanced XLR MIC IN should
be used to connect a microphone.
◊ ◊ The MIC500USB's MIC and HI-Z
inputs should never be used
simultaneously!
(16)
The ¼" TRS 1/L HI-Z IN can be used
to connect your electric guitar, for
example. This input is wired parallel to
the XLR input.
(17)
This balanced ¼" TRS 2/R LINE IN can
be used to connect a line-level balanced
audio source. The audio passes directly
to an analog to digital converter and
is then sent to a computer via the USB
port. The source can be monitored
directly in the headphones by pressing
the DIRECT MONITOR switch (adjust the
OUTPUT knob to suit). Any audio coming
into this input is not aff ected by the
other controls, switches, modes, or the
tube section.
