Build-Up Bluetooth system

Bluetooth Audio with Cha-Cha surface-mounted speakers for every hotel room

In addition to a Bluetooth system with ceiling speakers, there is also a system with the Cha-Cha surface-mounted speakers within the HRA range. The mounting plate makes it easy to mount the speaker against a wall. A hotel room can be provided with high-quality Bluetooth audio quickly and easily. The small Cha-Cha speakers are only 15 cm high and together with the compact receiver / amplifier can provide the more demanding guest with unprecedented audio. This series is delivered in consultation, personalized (per room/suite). Read below all the possibilities of this series.

Cha-Cha Bluetooth Hotel Audio System

Personalized per room ...

Every Bluetooth audio system is supplied custom-made. This way every suite has a personalized product. And the guest in his own suite can only link to the set of which he knows the code.

The maximum volume is set in advance. A guest can never cause any nuisance in one of the neighbouring rooms, but he can optimally enjoy high quality music... streamed from his own device.

Unique Bluetooth name, for example "Room 301", "Room 302" or "Room 412", but also "Hotel Lakeview / 416". Everything is possible. You provide the names and we ensure that each system has its own unique ID.


A unique 4-digit code ensures that each guest can only link to that system for which the code is found in his / her room. This way you can never accidentally connect to a system in a neighbouring room.

Quickly installed through the mounting plate


The Bluetooth (4.0) technology ensures a stable and interference-free sound transmission of up to 10 meters. Once an iPhone / SmartPhone is connected, your guest can move freely through the entire room / suite and stream the music of his or her choice.

12V power supply

The Mini-Box is characterized by combining the compact design with high power: 50 Watt (20W RMS). This power is supplied by an external power supply of 230V / 12v. The Mini-Box can easily be placed out of sight of the user. Simply connect the Cha Cha speakers to the Mini-box and the system is ready for use.

Or black

Your guest is in control

Your guest always stays 'in control'. The guest simply uses his own APPs or favorite music. The sound is always streamed to the Bluetooth Music Center in the hotel room. That is maximum enjoyment.

Installed quickly

The installation does not have to take longer than 8-10 minutes. A piece of cake for any installer. This keeps installation costs to a minimum.

Plug & Play

Technical knowledge is not required. The Cha-Cha speakers are connected to the Mini-Box using normal speaker cords. This Mini-box in turn is plugged in and the system is immediately ready for use.

Even greater range

The range of the mini-box is already very generous (up to 15 meters in the open field), but sometimes it can be useful to 'stretch' this range within the room walls. Then install the optional 'extension kit'. The white antenna is mounted on the visible side of the ceiling... the mini-box out of sight.
