Make use of existing items and make objects, furniture, and surfaces resonate with our technical Bluetooth master solution!
With our BTR405 LV Exciter Set, consisting of a 12-24 V Bluetooth receiver and 2x Exciter X32-4 Ohm, you now get an invisible and exciting sound. Connected to the surface - you can listen to music without traditional speakers via suspended ceilings, walls, and existing furniture. Enjoy your favorite music from your smartphone, tablet, or laptop via Bluetooth without having to see the sound system. In addition, music from a CD player, radio, or stereo system can also be listened to via the integrated Line In.
Do you want to listen to music wirelessly via Bluetooth, but due to your room concept - for space or aesthetic reasons - the Bluetooth system including the speakers should not be visible? Then our powerful Bluetooth receiver BTR 405 LV in combination with the exciters from our "Invisible Sound System" category is perfect for you: Attach the 2 included surface transducers to the desired surface behind ceilings, walls, mirrors, cabinet doors, furniture or even in counters and install the audio receiver in the respective desired cavity.
Whether kitchen fronts, cabinet side panels or baseboards - even glass fronts, mirrors as well as projection surfaces and whiteboards become speakers thanks to WHD exciters. Thanks to the self-adhesive film already applied on delivery, our "invisible speaker" can be horizontally glued to many different surfaces, which then serve as resonators. Vertical placement can also be achieved by screwing. With our positioning aid, you can playfully determine the ideal position for attaching the exciters, so that you get amazing sound quality despite different surfaces such as wood, glass or aluminum.
In public areas, the listed installation options can offer protection against vandalism. In areas where climatic conditions play a role, our Bluetooth system can be optimally placed and concealed so that heat, cold, moisture, dust or other influences do not have to pose any difficulties. Also in rooms where the highest hygienic requirements prevail and conventional sound systems are out of the question, our discreetly installed sound system offers a musical experience for relaxation, motivation and concentration.
Furthermore, the Bluetooth receiver BTR405 LV is more compact in height and width than our BTR405. This means that this product can be used in even smaller and narrower cavities, taking into account the dimensions.
The X 32 structure-borne sound transducer impresses with its very good bass reproduction. The values for sound pressure level, frequency range and radiation angle depend on the material used. Depending on the placement and material, you get an impressive sound reproduction that is sufficient for background music.
Simply connect an external 12-24 V power supply and attach the exciters - our so-called "invisible speakers" - to the desired surface. Thanks to simple Bluetooth pairing and handling, you can hear the music world of the internet or from the internal and external memory of an end device. If desired, stream music from many popular music apps such as Spotify, Deezer, SoundCloud, AppleMusic, YouTube, Amazon Music, TuneIn, Napster, TIDAL or listen to your playlists from your hard drive. Using our free "WHD Multiroom Player" app, over 1000 integrated internet radio stations can be played.
By directly connecting an external music source via RCA, music from a CD player, radio, or stereo system can also be listened to. For this purpose, the BTR 405 LV is equipped with a LINE IN. The music transmission is lossless. This means you get excellent audio transmission of your music collection in recorded quality.
The Bluetooth receiver BTR405 LV has a range of 10m, which maintains a stable connection between the devices and ensures interference-free sound reproduction. Thanks to the speaker cables, which are already connected to the sound bodies and have a length of 2m, perfect signal transmission can be guaranteed.
Our Bluetooth system is perfectly designed for background music and also has a low energy consumption of 36 watts. The two included 4 Ohm exciters are each supplied with an amplifier power of 10 W. Despite the low amplifier power, very good acoustic performance is reproduced, which is completely sufficient for background music and ensures low power consumption. Due to the already integrated stereo amplifier, no further amplifier is required.
Thanks to the additional settings via our Android app "BTR Configuration": assigning a Bluetooth name and access PIN, as well as setting the max. volume, several BTR 405/BTR 405 LV can be used within range. This Bluetooth sound system is therefore not only ideal for homes and offices, but also in public areas such as waiting rooms, receptions, and hotel rooms. In addition, our Bluetooth system is suitable for mobile applications such as caravans and ships and is certainly a great asset in campsites and holiday villages in the respective mobile homes, chalets, and lodges.
If you have a BTR405 LV Exciter Set in the bathroom, sauna area and kitchen, all devices within range can be recognized by your smartphone, tablet or laptop. By individually naming the Bluetooth receiver, you get the correct assignment. Listen to music from the bathtub and relax to the fullest. With background music in your sauna, you can let your thoughts drift away from everyday life and let your imagination run wild. You can also enjoy music in the kitchen at any time while you prepare dinner to the fullest.
