Omnitronic VC-22 Monitorkiezer/controller

Desktop Monitor Controller with Bluetooth for Compact Studios

The Omnitronic VC-22 is an active desktop monitor controller combining Bluetooth wireless playback, source switching, and monitor A/B comparison in one compact unit. It sits between an audio interface, a computer, and powered studio monitors as a central volume and routing hub for project studios and content creators. Housed in a matt black chassis measuring 138 x 64 x 120 mm and weighing 0.57 kg, it keeps the desk footprint minimal. Power comes from a USB-C port (5 V DC, approx. 500 mA), with a USB-A to USB-C cable included.

Bluetooth, Monitor A/B, and Mix-Check Tools in One Box

The built-in Bluetooth module streams audio wirelessly from phones, tablets, and laptops, appearing as "VC-22" in the device list. A speaker selector switch toggles between two pairs of studio monitors for instant A/B comparison, while dedicated mute, mono sum, and dim controls deliver the classic mix-check workflow without touching the DAW.

Three Input Sources for Any Studio Setup

The VC-22 takes two switchable analog sources (A/B) plus Bluetooth, which plays in parallel with the selected analog source, so a mix session, a reference track and quick phone playback can be heard without re-patching.

• Line Input: 2 x 6.3 mm TRS jack L/R (sources A and B) — balanced connection from an audio interface or mixer
• AUX Input: 3.5 mm stereo jack on source B — for phones and portable players, takes priority over the 6.3 mm jacks
• Bluetooth Input: wireless streaming — cable-free playback from mobile devices

Two Switchable Monitor Pairs for A/B Comparison

The output stage drives two pairs of 6.3 mm TRS jacks, feeding two separate sets of powered studio monitors from a single desktop unit.

• Monitor Outputs: 4 x 6.3 mm TRS jack (2 switchable stereo pairs) — connect two pairs of powered monitors
• Speaker Selector: switch routes the selected source to pair A or pair B — instant A/B comparison
• DI Output / S/PDIF: not included — analog-only signal path

Front-Panel Controls and USB-C Power

Every key function has its own control, so the engineer never has to dive into software mid-session. The rotary knob handles master volume, while dedicated switches cover mute, mono sum, dim, input source selection, monitor pair selection, and Bluetooth pairing. No microphone input, no phantom power, and no DI box — the VC-22 is a dedicated monitor-management device.

• Controls: Volume, Mute, Mono, Dim, Input Source Select, Monitor Select, Bluetooth pairing — full mix-check workflow from the desk
• Power Supply: USB-C, 5 V DC, approx. 500 mA — bus-powered from computer or USB charger
• Dimensions: 138 x 64 x 120 mm — compact desktop footprint
• Weight: 0.57 kg — light enough to reposition or travel with
