The AlphaTheta DJM-A7 is compatible with rekordbox for Mac/Windows, Serato DJ Pro, djay Pro for Mac and Windows, and djay for iOS. A subscription is required for Serato DJ Pro, djay Pro and djay for iOS. rekordbox for Mac/Windows is available through Hardware Unlock.

Adjust the sound to the room

Master Texture provides separate controls for shaping the high and low frequencies from the main speakers. Soft Mix Curve gradually reduces high frequencies as the channel fader is lowered. The mixer also includes four Sound Color FX: Space, Dub Echo, Split Filter and Filter.

Effects and wireless monitoring

Six illuminated buttons select the Beat FX: Delay, Spiral, Trans, Echo, Reverb and Roll. Built-in SonicLink supports wireless monitoring with compatible headphones. Touch Pairing is supported with the AlphaTheta HDJ-F9.

Link Cue and MULTI I/O

When connected to a PRO DJ LINK-compatible multi player, Link Cue lets you monitor a track or playback position through your headphones. Touch Preview and Touch Cue require a compatible multi player.

The MULTI I/O port connects to the AlphaTheta RMX-IGNITE using a USB cable, with digital audio sent between the mixer and effector.

AlphaTheta HDJ-F9

Wireless DJ monitoring with SonicLink

The HDJ-F9 is a professional on-ear DJ headphone featuring AlphaTheta’s SonicLink wireless technology. With latency as low as 9 ms, SonicLink is designed for responsive monitoring while mixing and scratching. Touch the headphones to compatible DJ equipment, such as the DJM-V5, for SonicLink touch pairing. For mixers or devices without SonicLink, the separately sold HP-TX01 transmitter can provide a connection.

Sound designed for the booth

The newly developed 40 mm drivers deliver low frequencies down to the sub-bass range. A bass-reflex chamber helps reproduce the attack of basslines and kicks, while the PEEK-PU-PEEK composite diaphragm suppresses unwanted vibration for balanced mid-to-high frequencies. The optimised internal structure reduces external noise, helping you monitor without needing to push the volume too high.

Flexible fit and durable construction

Swivel-mounted hangers and a flexible silicone headband let you monitor with one or both ears, or rest the headphones on your shoulders. The adjustable slider is made from die-cast aluminium, and the headphones have passed international durability tests.

Bluetooth, app features and wired listening

Multipoint Bluetooth lets you connect to two devices at the same time and switch between them. Google Fast Pair and Windows Swift Pair are also supported. Use the HEADPHONES CONNECT app to adjust the Status LED colour and brightness, rename the headphones, configure auto-power-off and voice assistant settings, and use the Find My Headphones feature to play a sound to help locate them.

For wired monitoring, connect the supplied coiled cable. The package also includes a USB-C charging cable, a 6.3 mm stereo adapter and a carrying pouch.
