ULTRAMIC384KEVO
ULTRAMIC192KEVO
High-performance dual-sensor Ultrasonic USB microphone

Overview

Ultramics are USB audio and ultrasonic microphones.
Two versions are available:
– UM384K USB MICROPHONE with 384 kHz sampling rate and 190kHz bandwidth
– UM384K USB MICROPHONE with 192 kHz sampling rate and 95kHz bandwidth
This means that you can record sounds up to about 190 kHz or up to 95 kHz.
The USB 2.0 full speed port allows an easy connection to your PC, iOS, Android smartphone or tablet and to embedded Linux systems.

The microphone is provided (optional) with a magnetic cone that makes the microphone more directional.
The cone can be easily removed by pulling it from the tip making the microphone omnidirectional, moreover, the cone provides protection to the sensor.
The magnets keep the cone close to the sensor.

Features

• A high-performance dual-sensor- omnidirectional audio and ultrasonic microphone
• USB 2.0 full speed connection using a driverless – standard audio class UAC 1.1 interface for an easier communication with host devices
• Hardware amplification gain is settled via four switches

Applications

• BIOACOUSTICS:
  o Detecting and recording of biological ultrasounds for bioacoustics studies on insects, cetaceans, rodents, and bats.
  o Environmental studies to assess the impact of wind farms on bats.
  o Recording and analyzing mice ultrasonic vocalizations for pharmacological studies.
  o Soundtracks and special effects (such as slowing down the recorded ultrasounds).
•  INDUSTRIAL:
  o LEAK detection
  o Predictive motor fault monitoring
  o Detection of high-frequency noises emitted by switching power supplies, LCD screens, or the turbines of car and truck engines, energy-saving lamps.
  The use of a standard USB audio class allows the microphone to be used as a standard Plug & Play device with no driver installation required.
  … WITH YOUR PC
  Insert the USB connector of the microphone to the USB connector of your PC.
  Less than a minute is required for the operating system of your PC to install the required software.

Q&A

Q: How can I connect Ultraimc384K to my own analog recorder?
A: Ultramic384K doesn’t need a separate recorder and cannot be connected to an analog recorder since the only output is digital (USB). Use the integrated recorder instead.
__________________________
Q: Can I record audio and Ultrasound at the same time?
A: Yes, Ultramic384K_EVO has no high pass filter so you can record audio and ultrasound at the same time.
__________________________
Q: I want to listen and view the spectrograms of acoustical signals.
A: Connect your Ultramic384K to your smartphone, tablet or PC and use your preferred app. The list of compatible apps is available on www.dodotronic.com.
__________________________
Q: My software can’t get the audio stream from UM384K.
A: Not all the software allows a so high sampling rate, check if the sampling rate can be set to 384 Khz. Select the right sound source.
__________________________
Q: I’m recording in real-time but from the spectrogram, I see only a valid bandwidth up to 20 Khz.
A: probably you have chosen the wrong sound source, try to change the sound source from the PC microphone to UM384K.
