1. Introduction
One interface to reach them all
TechnicaDelArte’s uMi U B Microphone interface is one of the world’s most flexible
professional Recording and Broadcasting interfaces. Delivering outstanding audio quality,
the uMi represents the centerpiece for recordings and live broadcasting. With the mobile
reporter in mind, our development team has designed a very robust and versatile
microphone amplifier.
The D P processing included within the uMi makes the user interface customizable. With
the help of uMi, your favorite microphone will sound the same, wherever you are.
24+1 bit/192 kHz ound Quality
Designed to play the central role in mobile situations, uMi delivers uncompromising audio
quality for all mobile devices: iO , Android, Mac O and Windows. By carefully selecting
the audio components we have built a device that offers extremely high-resolution sound,
with the lowest THD and high dynamic range.
Realtime D P processing
While the analogue sound is natural and transparent, the uMi can deliver a wide range of
dynamic processing, gain control and equalization via its hardware accelerated D P power.
Years of research and development by our experienced team has resulted in outstanding
audio quality processing algorithms, focused on mobile recording and broadcasting.
By saving presets within the device, sound colour and response can be adjusted simply by
the push of a button. The presets can be adjusted and stored in the device with the help
of the highly intuitive uMi Control user interface, available for Apple O and Windows.
Broadcasting two streams
Due to its flexible architecture, two uMis can be cascaded and used simultaneously in one
system. This feature has been created with the sports commentator in mind who, in most
cases, need separate microphones.
Elegant and robust hardware design
Working with the very best hardware materials and the most advanced manufacturing
processes, we have been able to deliver an outstanding quality device. Due to its
durability, the uMi can be used in the harshest of environments, which makes it the perfect
tool for on-the-road recording and broadcasting.

5. Hardware & block diagram
(1) Microphone connector.
XLR Female connector for connecting any dynamic microphone or a condenser
microphone that supports a phantom power voltage of 12V or lower.
(2) Mogami Neglex quad cable
2m (6,5ft) quad-core microphone cable. Extends the distance between the microphone
and the mobile device. The quad-core is used to improve the noise canceling (10 to 20dB)
of the connection between the microphone and the preamplifier.
(3) Phantom power switch
The phantom power can be activated and controlled via the uMi Control software. The
output voltage can be set between 0 and 12V. This is done to lower the current drain from
the U B port. This feature will increase the live time of the mobile device and makes sure
the power can be supplied by the mobile device.
(4) Preamplifier
The microphone signal is pre-amplified by an ultra-low noise analogue amplifier with a
fixed gain. The preamplifier also provides adequate input impedance, matching most
microphones.
(5) Analog to Digital converter
For converting the analogue microphone signal to the digital domain. The converter used
is a premium quality Cirrus Logic Analogue to Digital converter. The two input channels of
the ADC are used to convert one Mono microphone signal. This improves the noise
response of the conversion.
(6) Digital ignal Processor
This is the main core of the uMi. The D P handles the digitally converted audio signal from
the ADC to the U B port. The D P includes a Channel- trip functionality containing several
hardware accelerated D P effects.

(7) Preset button
Two presets can be stored in the hardware memory of the uMi. The user can switch
between these two presets by pressing this button. A blue LED light will indicate the
currently active preset.
The push button can also be used to update the firmware of the uMi if needed.
(8) U B port connector
U B-A Male connector compatible with any U B-A port and / or a Lighting connector.
6. uMi Control software
The uMi Control software can be downloaded from http://umi-connect.com/
Installing the uMi control software
After downloading the installer, double-click the installer icon and follow the onscreen
instructions until completed.
The User interface
Main feature: uMi is capable of storing two presets in its hardware memory. witching
between the two presets is achieved by pressing the hardware push button.
The selected OFF and ON -presets (9)/(10) are indicated with the LED placed in the
button's cap.
