Two versions are available: - UM384K USB MICROPHONE with 384 kHz sampling rate and 190kHz bandwidth - UM192K 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 pulling it from the tip making the microphone omnidirectional, moreover the cone provides a protection to the sensor. The magnets keep the cone close to the sensor. 2 ULTRAMIC384K EVO USER GUIDE DODOTRONIC Features A high performance dual sensor- omnidirectional audio and ultrasonic microphone USB 2.0 full speed connection using a driverless - audio class UAC 1.1 interface for an easier com- munication with host devices Hardware amplification gain is settled via four level switch USB connection Connect your Ultramic384K to your smartphone with a USB OTG adaptor 3 ULTRAMIC384K EVO USER GUIDE Planar plot DODOTRONIC ULTRAMIC384k_EVO with cone mounted ULTRAMIC384k_EVO with cone unmounted 4 ULTRAMIC384K EVO USER GUIDE DODOTRONIC Frequency response Attenuation dB Frequency response Ultramic384K_EVO 0 10 20 30 40 50 60 70 80 90 100 110 120 130 140 150 160 170 180 190 -20 -40 -60 -80 -100 -120 KHz 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 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. Install your preferred audio software. The list of compatible software can be found on: www.dodotronic.com ... WITH YOUR SMARTPHONE OR TABLET Use a USB OTG adapter and connect the Ultramic to your Android smartphone. Download the BAT RECORDER app and open it. Connect your headphones to listen the ultrasound translated in audio range. The online user guide will lead you to understand the many available features. 5 ULTRAMIC384K EVO USER GUIDE DODOTRONIC How to setup Audacity with Ultramic384K_EVO 6 ULTRAMIC384K EVO USER GUIDE DODOTRONIC 7 ULTRAMIC384K EVO USER GUIDE DODOTRONIC 8 ULTRAMIC384K EVO USER GUIDE DODOTRONIC 9 ULTRAMIC384K EVO USER GUIDE DODOTRONIC Technical Specifications Recording format USB B connector External dimensions Weight Switch gain settings referred to 1 kHz 94 dB SPL = 0 dB Sampling frequency Resolution Amplification CPU Power Microphone sensor Linear PCM (Pulse Code Modulation) format USB 2.0 Full Speed USB audio class 1.1 Ultramic = 80 W x 30 L x 16 H mm Cone = 37 W x 25 L x 18 H mm 24 g 1 -33 dB 2 -10dB 3 0dB 4 10dB 384 kHz/second or 192kHz/second 16 bit High quality, and low noise, amplification with low pass filter with cutting frequency of 190 kHz or 95kHz 32 bit integrated ARM Cortex M4 microcontroller 15 mA power requirement when connected to a USB host Dual MEMS sensor Test devices: SENSOR = BRÜEL & KJÆR 4138 PREAMPLI= BRÜEL & KJÆR 2669 AMPLI= BRÜEL & KJÆR NEXUS 2690; software version Boot: 1.10, application 2.50.

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 high sampling rates used by Ultramic, check if the sampling rate of your software can be set to 384 kHz. Select the correct 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 selected the wrong sound source, try to change the sound source from the PC microphone to UM384K. _________________________ Technical assistance and support Send request to: info@dodotronic.com 11 ULTRAMIC384K EVO USER GUIDE DODOTRONIC Safety Precautions Before using this device, read this manual carefully to ensure that you know how to operate the Ultramic384K safely and correctly.
