Adastra DM Series 100V Mixer Amplifier with Bluetooth

The Adastra DM Series is a compact 100V line mixer-amplifier with a built-in digital amplifier, available in 25W, 40W, and 60W output variants — offering an all-in-one solution for small sound installations where simplicity and a small footprint matter.

An onboard media player handles USB audio playback and FM radio tuning, while Bluetooth connectivity allows a smartphone or tablet to be paired wirelessly for audio streaming. All three sources are managed from the front panel alongside dedicated controls for mic, aux, bass, and treble — keeping operation straightforward for day-to-day users.

Speaker output is switchable between 100V line and 4–16 Ohm low-impedance loads via spring terminals on the rear panel, making it compatible with both 100V line speaker systems and standard speakers. A stereo RCA line input is summed to mono, and a line output is provided for connecting additional amplification if needed.

• Built-in USB Player and FM Tuner: Play audio from a USB drive (FAT32, up to 128 GB) or tune to FM radio stations without any external source equipment.
• Bluetooth Wireless Streaming: Pair a smartphone or tablet to stream audio wirelessly — ideal for venues where flexible source switching is needed.
• 100V or 4–16 Ohm Output: Supports both 100V line speaker systems and standard low-impedance speakers, covering a wide range of installation types.
• Compact Housing: A small physical footprint makes the DM Series easy to install discreetly on a shelf, in a cabinet, or in a compact rack enclosure.
• Front Panel Controls: Separate volume controls for mic, aux, and the media player section, plus bass and treble EQ, keep the system easy to operate without technical knowledge.
• Line Output: Dual RCA line output allows the signal to be passed on to additional amplifiers if the installation needs to be expanded.
