Built-in RGB backlighting and configurable real-time effects add visual and sonic flexibility for streaming environments.

How to use

Connect the Solocaster to a computer, tablet, smartphone or console via the supplied USB-C cable; the unit will appear as a USB audio interface. Plug a microphone into the XLR input (enable 48V phantom power if using a condenser mic), or connect instruments and line-level devices to the 3.5 mm inputs and pair a mobile device via Bluetooth if needed. Adjust the three main channel levels with the faders, set monitoring volume on the headphone output, and use the effect pads or voice-change buttons to add or trigger sounds in real time. For direct recording, enable internal recording/loopback to send the mixed signal to your streaming or recording software.

Usage recommendations

For best results, use a high-quality XLR microphone with phantom power for vocal recording, monitor levels via headphones to avoid clipping, and enable Intelligent Noise Reduction when streaming from noisy environments. When using backing tracks, activate Smart Ducking to keep dialogue clear and set effect pad levels in a short pre-check to ensure smooth playback during live streams.
