APPLICATIONS:
Microphone Pre Amplifier:
The
USB Dual Pre
can be used as a high quality microphone preamplifier suitable for
all dynamic, condenser, and ribbon microphones. Most conventional mixers utilize budget
minded microphone preamps and while very functional, they do not sound all that great. The
USB Dual Pre
serves as a quality upgrade that will give you more flexibility and a more robust
tone than standard mixer preamps.
Simply plug a microphone into the XLR input. Apply phantom power if using a condens-
er. Then dial up the gain and you are ready to go. Refer to the LEDs on the front for a visual
measure
of input gain, and then route the output to a mixer, workstation, or computer via the
1/4-inch or USB output. The overall analog output level can be adjusted right at the unit.
Since the
USB Dual Pre
can be battery powered or run totally off the USB bus, it is
ideal as a portable microphone preamp for remote performance or laptop recording.
Phantom Power Supply:
Many mixers, workstations, and computer interface boxes will not 48 Volt phan-
tom power on all microphone inputs. This is a critical feature if you plan to use a condenser
microphone. The
USB Dual Pre
is a perfect solution to this problem, letting you connect any
microphones to your existing mixer or computer. Operation is identical to what is covered
above. Once again portable laptop recording with high quality condenser microphones that re-
quire real phantom power is possible.
Instrument DI:
The
USB Dual Pre
will work well as a very functional DI for Bass, Acoustic Guitar and
virtually any other instrument with a 1/4-inch or XLR output. Many people prefer the sound of
ART preamps for responsiveness instead of standard DI’s and preamps. You will also enjoy
more flexibility and control over a standard DI.
Operation is simple, insert the output of the instrument into the input of the
USB Dual
Pre
. Make sure the volume on the bass or guitar is up most of the way. If you are using any ef-
fects, make sure that the overall output is not greatly increased when the effect is on. Adjust
the input gain knob and refer to the LEDs on the front for a visual measure of input gain. Then
route the output to a mixer, workstation or computer via the 1/4-inch, or USB output. The over-
all output can be adjusted at the unit. Both analog outputs and the USB port may be used at
the same time so the 1/4-inch can be routed to an amplifier or monitor system and the USB to
a computer. Using the built-in monitor mixer for monitoring during the record process gives you
the most flexibility.
