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 supply +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.
