The AlphaTheta DJM-A7 is a 4-channel DJ mixer for smaller venues such as clubs, bars, restaurants and hotels. It carries over the layout and sound of the DJM-A9 in a more compact body, and its two USB Type-C ports let two DJs stay connected for back-to-back sets and changeovers.

Software and Devices

The DJM-A7 works with rekordbox and djay Pro for Mac/Windows, Serato DJ Pro and djay for iOS, so DJs can bring a laptop, iPhone or iPad and start mixing right away. rekordbox is unlocked by the mixer with no license needed; djay Pro, djay for iOS and Serato DJ Pro need a subscription.

Sound

The DJM-A7 inherits the clear, neutral sound of the DJM-A9, with 32-bit A/D and D/A converters refined through listening tests at clubs and venues. Two Master Texture knobs adjust the Air (highs) and Low End (lows) of the main output independently, so DJs or venue staff can suit the sound to the room and the music without a sound engineer.

SonicLink Wireless Monitoring

SonicLink is built into the mixer, with 9 ms latency and no separate transmitter to charge or connect. It works with the HDJ-F10 and HDJ-F9 headphones, and the HDJ-F9 pairs by Touch Pairing: touch its left earcup to the headphone touch area on the front of the mixer.

Mixing and Effects

• Soft Mix Curve: gently reduces the high frequencies as you lower a channel fader, for smoother blends
• Sound Color FX: Space, Dub Echo, Filter and the new Split Filter, which shapes mainly the midrange while keeping the highs and lows of the track moving
• Beat FX: Delay, Spiral, Trans, Echo, Reverb and Roll, chosen with 6 illuminated buttons that are easy to read in a dark booth
• Link Cue: with a PRO DJ LINK player, Touch Preview auditions a track before you load it and Touch Cue checks any point of the playing track without affecting the master output
• MULTI I/O: one USB cable connects the RMX-IGNITE, DJM-REC or RMX-1000 for iPad, with audio sent and received digitally
