      Luna Lure UMP-2 - multipurpose mobile ultrasound device

      Luna Lure UMP-2 – multipurpose mobile ultrasound device

      Luna Lure UMP-2 is an improved and enhanced design of our first  Luna Lure UMP-1 ultrasonic player. It is a complete device for broadband playback or luring bats or other animals thanks to a wide spectrum of reproduced frequencies. Works on the reproduction of audible or ultrasonic sounds from recordings in the form of WAV, MP3, FLAC or APE files, mono or stereo (single or dual channel) recorded on SD / SDHC / SDXC memory cards. Built-in power supply (8 AA / R6 cells – primary or rechargeable batteries) and allows up to several hours of field operation. External power can be also connected if needed. The uniqueness of this design over the competition lies in its reduced weight and external dimensions while having higher output power at the same time and a higher ultrasonic propagation angle (no speaker collar/flange, better speaker protection against animals in the form of an acoustically transparent metal mesh) and the ability to connect an external signal source via the LINE- IN connector (the device works also as an ultrasonic active speaker).
      Greater output power of the internal amplifier is used for boosting the propagation distance and for compensation of frequency response of the transducer, so that the reproduced band is also wider, which allows the reproduction of echolocation eg small horseshoes (Rhinolophus hipposideros) and all other bats. It is also possible to play the social voices of bats and even the singing of most birds by the relatively low frequency limit from about 1 kHz. In addition Luna Lure UMP-2 can be connected to active ultrasonic speakers Luna Speaker UMS-1 with its own independent internal amplifer and power supply via LINE-OUT connector and low-loss signal cable, for example to further expand the beam width (eg, to direct the ultrasound in opposite directions on both sides of the net) or increase the radiated power in a given direction. By using two channel processing of the recordings from the memory card when connecting an additional external speaker Luna Speaker UMS-1 or another Luna Lure device – two independent sources of sound or ultrasound can be obtained. Ultrasonic reproduction from audio recorders or bat detectors and even the recordings from time-expansion detectors is also possible – files for playback need to be converted to a suitable sampling rate in any audio editor, such as Audacity. Additionally, the control panel has added buttons to switch files (PREVIOUS “<<” / NEXT “>>“) But START “>” / PAUSE “||” switch also allows you to switch to USB-DAC mode or to work as an active speaker.
      A separate button is used to switch to loopback on a single current file mode (by default, looping of all files on the memory card is enabled).

      Tripod mount with standard 1/4″ UNC-20tpi thread

      At the bottom of the housing is a reinforced tripod female socket with so-called: “small photo thread” (UNC 1/4” 20tpi) for mounting on a standard photo tripods or UM-1 / UM-2 rails. At the bottom of the housing there are also four flexible feets for stable positioning on flat surfaces, and a stainless steel eyelet for mounting on a branch is mounted on the upper wall.
      Another unique feature is displaying the level of supply voltage on LEDBAR in 3 seconds after powering the device, so the user can quickly determine whether batteries or accumulators have enough energy to work with the device.

       

       

       

       

       

       

      * Planned development:

      There is also a USB-DAC interface built into the device, which can now play non-distorted sampled signals only up to 96kHz of sampling rate. The interface also allows transferring data to a memory card (the memory card slot is visible as an SD card reader). This interface, however, is intended for future broadband ultrasonic reproduction directly from the computer (it works as a one-way 2-channel DAQ card). Up to 96kHz sampling is possible on the software side, although the interface can run up to 384kHz on the hardware side. However, software drivers need to be fine tuned to reproduce the signal correctly at 176.4kHz, 192kHz, 352.8kHz and 384kHz. To switch the operation mode, press the PLAY / PAUSE button twice. When turned on again, the device reports as a mobile player. For ultrasound playback at frequencies higher than 48kHz directly from the computer with the device, you can now use a separate USB interface LunaDAC-1 available in our offer and LunaLure UMP-2 can be used as an active ultrasonic speaker.

      Recent news:

      During recent tests the internal USB-DAC interface can properly work with all sampling frequencies (44.1k, 48k, 88.2k, 96k, 176.4k, 192k, 352.8 and 384kHz) when connected to Apple/Mac laptop or tablet with newer OSX systems without the need to install any additional drivers (Apple OSX has its own built drivers and has native support for USB Audio Class 2.0 devices like internal interface in Luna Lure UMP-2).

      _____________________________________________

      * – for playback from memory card all sampling rates up to 384 kHz are available

      ** – via ASIO driver (can be used with popular Foobar player via foo-ASIO-out plugin). Driver for Windows XP/Vista/7/8/10 is provided on a memory card or in Download section. There is also the possibility to play from a PC via a WDM driver as a regular USB Audio Device – the playback is then limited to a maximum sampling rate of 96 kHz. Future development of drivers will unlock all higher sampling rates.

      *** – SDXC cards should be formatted using the FAT32 file system, eg using the program SD Formatter

      **** – Connectors are under the flap (bolted with two screws) with knurled heads that do not require a wrench (finger tightened)

      The Luna Lure UMP-2 device itself is sufficient for point-and-click lure from one direction.

      The hardware settings looks like this:

      Standard configuration with single channel / single speaker bat luring (player only)

      Configuration with single channel / single speaker bat luring (standalone player only)

      The bat (on the other side of the mist-net and in the axis of the speaker’s radiation of the ultrasound player) hears the familiar voices and curious / lured tho them it flies closer to the signal source, but on the way falls into the mist-net. Because of the direction of ultrasound radiation from the loudspeaker – their intensity rapidly decreases beyond the axis of the speaker’s radiation. In addition, the intensity decreases the faster, the greater is the frequency of the transmitted signal. As a result, a bat outside of the speaker’s axis (or even behind the speaker, on the same side of the net) will not hear the reproduced ultrasound and will not be lured / caught in the net.

      To remedy this problem, connect the active ultrasound speaker Luna Speaker UMS-1 to the LunaLure UMP-2 (using signal cable) and place it on the other side of the net:

      Standard configuration with single or double channel / double speaker bat luring

      Configuration with single or double channel / double speaker bat luring

      Due to the fact that the Luna Lure UMP-2 uses a unique dual channel processing solution and two DACs (Digital-to-Analog Converters) in a single enclosure, two different types of work are possible when connecting an active external speaker:

      • two-channel (stereo)/ two-speaker operation – the player’s loudspeaker reproduces the right channel (channel 1) from the file on the memory card (recorded as the dual channel / stereo WAV, FLAC or APE file), and the connected Luna Speaker UMS-1 plays the left channel signal (channel 2). This makes possible, for example, to play two different signals in different directions, which is closer to the situation in reality, because two bats can not give voices from the same place in space;
      • one-channel (mono)/ two-(or more)-speaker operation all devices: the speaker in the LunaLure UMP-2 player and the speaker(s) in the active speaker(s) Luna Speaker UMS-1 are reproducing the same signal from the recording on the memory card. To get this kind of work – the recordings should be prepared in the editor beforehand. You need to create single channel / mono recordings (you can also use stereo / dual channel recordings, but it should have the same signal in both channels, for example, after mixing them with each other).

      This second mode of operation (mono) can be particularly useful when you need to increase the range of luring by placing the devices side by side at a short distance and pointing them in the same direction (the power of the radiated signals from the individual devices will add up). You can also direct the individual devices in different directions, thus reducing the directional effect of the loudspeakers. In this way, the width of the radiated ultrasound beam can be broadened.

      The implications of using such a solution are many. For example, you can drive off two (or more) remote locations using only one Luna Lure UMP-2 player and one (or more) Luna Speaker UMS-1 connected to it. At the same time, the connection of the active speakers is cascaded – the first connected active speaker is connected to the second active speaker, etc. The total cost of such a solution is considerably lower than that of using separate playback devices for individual locations. And because of the much lower price of active speaker (even with long signal cable) than the separate player this is the more cost effective solution as there are more points in the area where the catches are to be carried out.

      Configuration of connecting three (or more) devices:

      Standard configuration with single or double channel / multi speaker bat luring

      Standard configuration with single or double channel / multi speaker bat luring

      In the above example, the “mixed” configuration is also possible, ie the LunaLure UMP-2 player reproduces channel 1 / right and the Luna Speaker UMS-1 active speakers reproduces channel 2 / left.

      The use of an active ultrasound speaker connected to a line-level source has the advantage (against the passive speakers in competing solutions) that the signal in low-current cable is not degraded (weakened and frequency-limited), as is the case with passive speaker connected via speaker cable. Thanks to this, the distribution of individual signal sources is not limited to a few meters. Losses in connection cables depend on many electrical parameters of the circuit, and most important is the ratio of cable impedance to impedance of the receiver / speaker (with the impedance of both components changing with frequency). For this reason, in the case of passive loudspeakers, already several meters of cable have large power losses, which are to be radiated by a speaker with a relatively low impedance (eg 4 ohm). When using a low-current signal cable, where the receiver has an incomparably higher impedance than the cable impedance, the signal can be transmitted at significant distances practically without loss (losses are imperceptibly small). This fact, as well as independent powering of the active speaker(s), causes longer operation of the whole system, without frequent battery replacement.
