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.

Channel- trip
The uMi hardware architecture permits the use of several audio Algorithms, accelerated in
the D P functionality of the interface itself.

uMi Manual Version 1.0 SEPTEMBER 2016 PAGE 12 / 17
Phantom
The Phantom power can be switched On/Off.
The output level can be set between 0 and 12V.
Low Cut
When activated, the input signal passes a low cut (high-pass) filter. This second order low
cut filter has a cutoff frequency that can be set between 1Hz and 150Hz and has a slope
of 12dB per octave.
Low Cut is used to remove rumble and unwanted low frequencies from the input signal.
Phase
The phase of the incoming signal can be inverted by activating this function.
Phase inversion can help reduce phase cancellations when more than one microphone is
used to record the same source.
Gain
The Gain (amplification) of the incoming microphone signal can be set between 0 and
60dB.
In the most cases the microphone signal will have to be amplified; the Gain function is
specially developed for this.

uMi Manual Version 1.0 SEPTEMBER 2016 PAGE 13 / 17
EQ Low
The incoming signal can be equalized with a LOW filter Equalizer. There are two options
included: helf and Parametric equalization.
helf Equalizer
The Gain can be set between -20 and +20dB.
The cutoff frequency can be set between 50 and 6400 Hz.
Parametric Equalizer
The Gain can be set between -20 and +20dB.
The Q factor can be set between 0.5 and 50.
The cutoff frequency can be set between 50 and 6400 Hz.
The EQ Low can be used to amplify / attenuate the low side of the audio spectrum to get
a better balance between the sound frequencies. The EQ low is often used to bring
brightness to the audio signal by boosting the low frequencies.
EQ High
The incoming signal can be equalized with a HIGH filter Equalizer. There are two options
included: helf and Parametric equalization.
helf Equalizer
The Gain can be set between -20 and +20dB.
The cutoff frequency can be set between 0.5 and 16 kHz.
Parametric Equalizer
The Gain can be set between -20 and +20dB.
The Q factor can be set between 0.5 and 50.
The cutoff frequency can be set between 0.5 and 16 kHz.
The EQ High can be used to amplify/attenuate the high side of the audio spectrum to get
a better balance between the sound frequencies. The EQ High is often used to soften
harsh vocals and reduce noise in the recording / broadcast.
Noise Gate
The Noise Gate can be switched ON/OFF in the channel-strip altering the audio signal.
Imagine standing in front of a fence gate and whispering, “I want to come in.” Nothing
happens. Then you yell, “I WANT TO COME IN” and this time the gate opens. The higher
volume level is what opened the gate.
This functionality is useful in very noisy environments.
Attack: controls the speed of the gate opening. Can be set between 0 and 200ms.
Release: controls the speed of the gate closing. Can be set between 0 and 1000ms.
Range: the amount of decibels reduction to the signal once the gate is closed. Can be set
between 0 and 100dB.
Close: at which audible level the gate closes. Can be set between -60 and 0dB.
Open: at which audible level the gate opens after being closed. Can be set between -60
and 0dB.

uMi Manual Version 1.0 SEPTEMBER 2016 PAGE 14 / 17
Volume
The volume of the outgoing audio signal can be set with this fader.
The volume fader can be set between -70 and +12dB.
If you switch on Lock, the level of your device is locked and cannot be changed by your
O . This is to prevent unwanted level changes when you use the uMi in different
Applications or O ’s
Limiter
The Limiter s always activated and attenuates the audio signal when it exceeds 0dB.
The Limiter is used to prevent digital distortion in the recording / broadcast when the
output level exceeds 0dB.
