Adastra Warehouse Music Sound System with Suspended Pendant Speakers, Bluetooth & DAB Radio
This Adastra RM Series background music system is designed for warehouses, retail units, supermarkets, and large open spaces with high or suspended ceilings.
Designed For Large Open Commercial Spaces
This professionally configured background music system is ideal for commercial environments where traditional ceiling speakers are not practical. Built around Adastra’s reliable RM-series mixer amplifiers and suspended pendant speakers, it delivers clear, evenly distributed audio across large open areas such as warehouses, DIY stores, supermarkets, and garden centres.
Pendant speakers are particularly effective in buildings with high or suspended ceilings, providing focused downward sound coverage where it is needed most, without the loss of clarity often experienced with wall-mounted or standard ceiling speakers.
Flexible Speaker Quantities & Finishes
The system is available with a choice of 4, 6, or 8 Adastra pendant speakers, finished in black or white, allowing the system to be tailored to both the size of the space and the interior design. This flexibility makes it suitable for a wide range of commercial installations, from smaller retail units to larger warehouse-style premises.
As a 100V line system, speaker power tappings can be adjusted to balance volume levels across the space or allow for future expansion if additional speakers are required.
Choose The Right Speaker Size For Your Space
You can select between two pendant speaker driver sizes depending on your application and sound requirements.
The PS50 5" pendant speakers are ideal for speech, paging, and light background music in quieter environments or smaller areas, offering clear and intelligible audio.
The PS65 6.5" pendant speakers provide increased low-frequency response and higher output, making them better suited to larger spaces or environments where fuller background music is required.
This clear choice ensures the system is matched correctly to the size and acoustic demands of your venue.
Matched Amplification For Reliable Performance
To ensure optimal performance and sufficient system headroom, the amplifier is matched to the selected speaker quantity.
The Adastra RM120D 120W mixer amplifier is supplied with the 4 and 6 speaker systems, while the Adastra RM240D 240W mixer amplifier is included with the 8 speaker system. Both amplifiers offer stable 100V line operation, dependable performance, and flexibility for future system growth.
Multiple Playback & Control Options
Each amplifier includes a comprehensive range of playback options, making it easy to integrate into any commercial environment.
Bluetooth wireless streaming allows music playback directly from smartphones, tablets, or laptops. A built-in DAB+ digital radio tuner provides access to a wide range of stations, while the USB/SD MP3 player enables stored audio playback without external devices.
Microphone inputs with priority override make the system suitable for announcements, paging, and safety messages, ensuring important audio is clearly heard when required.
Wide Coverage & Easy System Balancing
The pendant speakers feature a wide 140° dispersion angle, allowing them to be strategically positioned for consistent sound coverage across large open areas. Rear-mounted rotary switches enable individual power tappings to be selected, making it easy to balance volume levels between different zones or areas within the same space.
Simple Installation & Complete Package
The system includes 100 metres of heavy-duty 2-core speaker cable, ensuring reliable signal transmission and straightforward installation.
The mixer amplifier is housed in a 2U 19" rack-mountable chassis with rack ears supplied, allowing it to be securely installed in a rack cabinet or positioned discreetly on a shelf away from public access.
