AlphaTheta OMNIS-DUO - portable all-in-one DJ system
The OMNIS-DUO is a genuinely portable DJ system built to play anywhere, powered by a built-in battery good for up to 5 hours without mains power. Compact and lightweight enough to slide into a backpack, it pairs a familiar 2-deck-plus-mixer layout with Wi-Fi, Bluetooth audio input and output, and professional XLR and RCA outputs - the first all-in-one DJ system to offer Bluetooth audio output, opening up genuinely spontaneous sets anywhere from a beach to a back garden.
Staff take: the expert verdict
The OMNIS-DUO is the unit we recommend to DJs who want to actually take their setup somewhere, not just describe it as portable. The 5-hour battery is real-world usable, not a marketing number, and Bluetooth audio output means you can genuinely pair it with a portable speaker and play a set with zero cables involved. It’s not trying to be a club-standard flagship - it’s solving a completely different problem, and it solves it well.
Why choose the AlphaTheta OMNIS-DUO?
-
Built-in battery - up to 5 hours of continuous playtime on a single charge, rechargeable via the included AC adapter or a compatible power bank (45W or more), with an Eco Mode to extend playtime further.
-
First all-in-one system with Bluetooth audio output - play wirelessly to Bluetooth-enabled speakers or headphones, ideal for beaches, campsites, or anywhere without a proper PA.
-
Bluetooth audio input - let guests connect their own devices and play tracks wirelessly, with all the unit’s effects available on the Bluetooth input too.
-
Versatile music sources - play from USB drives, SD cards, or connect a PC/Mac via USB-C for full rekordbox and Serato DJ Lite control; Wi-Fi also enables cloud and streaming access.
-
StreamingDirectPlay - stream directly from Beatport Streaming and TIDAL (subscriptions required) without needing to carry a USB library.
-
Familiar 2-deck + mixer layout - an interface that’s instantly usable for DJs of any level, with switchable Light and Dark touchscreen modes for visibility in any environment.

Professional outputs - XLR master output for connecting to professional sound systems, plus RCA output for home stereos and monitors.
-
Compact, lightweight design - rounded corners and a genuinely backpack-friendly footprint, in a distinctive indigo finish.
Who is the AlphaTheta OMNIS-DUO for?
The OMNIS-DUO is built for mobile DJs, casual performers, and anyone who wants a genuine DJ setup for spontaneous sessions - house parties, outdoor gatherings, beaches, campsites, or small bars - without hauling a full club rig. It also suits DJs who want a lightweight secondary system for practice or travel, and anyone who values the novelty of true wireless output to a Bluetooth speaker.
OMNIS-DUO vs XDJ-AN - what’s the difference?
Both are 2-channel AlphaTheta all-in-one systems, but they’re built for different situations. The XDJ-AN is designed around a club-standard CDJ/DJM layout to help DJs transition into playing real venues, with mains power and a fuller feature set aimed at that progression. The OMNIS-DUO trades some of that club-standard depth for genuine portability - a built-in battery, Bluetooth audio input and output, and a footprint built to travel. If your priority is building club-ready skills on a familiar professional layout, the XDJ-AN is the better fit. If your priority is taking a real DJ setup somewhere without mains power or cables, the OMNIS-DUO is built specifically for that.
Getting started with the OMNIS-DUO
- Charge the built-in battery via the included AC adapter, or connect a compatible power bank (45W or more) to the dedicated USB-C power input.

- Connect to Wi-Fi to access StreamingDirectPlay (Beatport Streaming, TIDAL) or your rekordbox cloud library.
- Pair a Bluetooth speaker or headphones for wireless output, or let a guest pair their phone via Bluetooth input to add tracks to your set.
- Route your main system via the XLR output for professional venues, or RCA for home stereo systems.
