BTR 405 LV, black - Bluetooth receiver 12-24 V

The BTR405 LV is a 12-24V Bluetooth receiver, with connections for up to 4 loudspeakers/exciters, which can be concealed in ceilings, furniture, and walls. Enjoy your favorite music from your smartphone, tablet, or laptop via Bluetooth through the connected loudspeakers or resonators/exciters. Additionally, music from a CD player, radio, or stereo system can be listened to via the integrated Line In.

Advantageous Installation Options

Do you want to wirelessly stream music via Bluetooth to loudspeakers/exciters, but due to your room concept - for space or aesthetic reasons - the technology should not be visible? Then our powerful Bluetooth receiver BTR 405 LV from our "Invisible Sound System" category is perfect for you: an audio receiver that can be invisibly installed in cavities such as ceilings, walls, furniture, behind mirrors, cabinets, cabinet doors, and counters. For more details for product manufacturers, see the video.

In public areas, hidden installation can provide protection against vandalism. In areas where climatic conditions play a role, our Bluetooth receiver can be optimally placed and installed so that heat, cold, humidity, dust, and other influences do not pose any difficulties.

Furthermore, the BTR405 LV is even more compact in height and width than our BTR405. This means that this product, considering its dimensions, can additionally be used in even smaller and narrower installation locations.

Streaming Made Easy

Connect an external 12-24 V power supply and easily connect the passive loudspeakers or exciters - our so-called "invisible loudspeakers" - via speaker cable. With simple Bluetooth pairing and handling, you can enjoy the music world of the internet or from the internal and external storage 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 (display logos) 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.

Diverse Music Program Beyond Streaming

By directly connecting an external music source via cinch, music from a CD player, radio, or stereo system can also be heard. The BTR 405 LV is equipped with a LINE IN for this purpose. The music transmission is lossless. This provides excellent audio transmission of your music collection in recorded quality.

Guaranteed Good Range

The Bluetooth receiver BTR405 LV has a range of 10m, which maintains a stable connection between devices and ensures undisturbed sound reproduction. Additionally, speaker cables up to 10 m in length can be connected, which also guarantees perfect signal transmission to the connected speaker boxes.

Ideal Performance for Background Music

Our Bluetooth system is perfectly designed for background music and also has low energy consumption. Either 2x 4Ohm loudspeakers/exciters with an amplifier output of 10 W per loudspeaker or 4x 8 Ohm loudspeakers/exciters with an amplifier output of 5 watts per loudspeaker can be connected. Despite the low amplifier output, 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.

Added Value Through Assignment and Protection Against Access

Thanks to the additional settings via our Android app "BTR Configuration": assigning a Bluetooth name and access PIN, and setting the max. volume, multiple BTR 405 LV units can be used within a single range. This makes this Bluetooth receiver ideal not only for homes and offices but also for public areas such as waiting rooms, receptions, and hotel rooms. Furthermore, our Bluetooth system is suitable for mobile applications such as caravans and boats 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 in the bathroom, sauna area, and kitchen, all devices within range can be recognized by your smartphone, tablet, or laptop. By assigning individual names to the Bluetooth receiver, you get the correct assignment. Listen to music from the bathtub and relax completely. With background music in your sauna, you can clear your mind from everyday life and let your thoughts run free. Also, enjoy music in the kitchen anytime while you fully prepare dinner.

Do you have a guesthouse? Every hotel room with a music interface offers your customers unforgettable moments. To ensure that guests can only access the device available in their hotel room, access PINs are assigned. Additionally, the maximum volume can be defined so that neighbors remain undisturbed. Our simple Bluetooth system creates atmospheric moments in your business premises and invites your customers/guests/patients to relax.

Good Sound - Anytime, Anywhere

The application possibilities for the BTR405 LV are diverse and endless. For certain applications where acoustics are altered by room-related sound, selectable preset sound profiles provide a solution. Thanks to DSP, the digital signal processor, you can choose between 6 sound presets in the "BTR Configuration" app, which optimize sound reproduction according to preference and room situation. Experience a pleasant atmosphere with good background music in every situation and every room, optimized and without loss of sound.

Modern Music Listening Can Be So Simple

Enjoy the wonderful new world of music by simply retrofitting a BTR405 LV in your premises. Connect new or existing loudspeakers via cable, whether they are passive ceiling-mounted loudspeakers, design loudspeakers, 2-way loudspeakers, stereo loudspeakers, surface-mounted loudspeakers, spot loudspeakers, hi-fi loudspeakers or tactile transducers. With simple Bluetooth pairing and handling, you'll be listening to your favorite music in no time.
