Switch Back Plus

Switch Back PLUS
The Switch Back PLUS is an all-in-one Dante audio interface, mixer, and MIDI control surface in a compact device. The PLUS consolidates into a single unique tool what would typically require multiple pieces of hardware. As your studio’s interface and controller or your personal mixer and stage box at a live event, the PLUS’ hybrid functionality provides space-conscious flexibility.

Simply connect the Switch Back PLUS via a Cat6 Ethernet cable to a PoE+ network switch, and you‘re integrated with your Dante-enabled devices. Plug in your headphones or speakers, route your audio channels through Dante, and let the creativity flow.

Multi-channel Mixer
Control volume, panning, and stereo width of up to 32 stereo Dante audio channels. Features zero-latency, master volume control, 4-band parametric master EQ, balanced stereo outputs, two headphone jacks, and sharp OLED screens which display channel names and status.

Audio Interface
The Switch Back PLUS features four local inputs including an XLR microphone input with switchable phantom power, a high-impedance instrument input with adjustable gain, and two balanced line-level inputs. Route these inputs, along with the main stereo mix, to other devices on the Dante network. Additionally, the PLUS presents four more default-muted Dante channels which mirror the four inputs and can be unmuted by pressing the BROADCAST button, allowing any of the inputs to be used as an intercom.

MIDI Control Surface
MIDI shares the same network connection as Dante to send and receive CCs. This allows the knobs to be used for controlling software and external hardware. Get real-time feedback of CC values via the LEDs above each knob.
