Description
Compact Mixing Anywhere
Qu-SB’s ultra-portable design allows you to mix from anywhere in the venue without being tied to a fixed console. It provides a smart, flexible solution for performing bands and artists while maintaining professional sound quality. Its compact form factor makes it easy to transport and set up quickly.
AnalogiQ Preamps
Sixteen AnalogiQ digitally controlled preamps deliver ultra-low noise and superb transparency from input to output, using zero-crossing detection and a padless 1 dB-step gain stage. This ensures clean, detailed audio with minimal distortion. The preamps are matched with 24-bit A/D and D/A converters for high-fidelity sound.
USB Recording & Streaming
Qu-SB features Qu-Drive, an integrated multitrack USB recorder for 18-channel 48kHz/24-bit recording and playback directly from USB drives or hard disks. The USB interface streams audio to Mac or PC, supporting all inputs, FX returns, and stereo mixes. It is compatible with major DAWs and enables effortless live streaming.
FX & Automatic Mic Mixing
Four stereo RackFX engines provide high-quality effects including classic reverbs, gated reverbs, delays, and modulators on dedicated return channels. The Automatic Mic Mixer (AMM) balances up to 16 microphones, reducing feedback and background noise. Together, they ensure polished live mixes with minimal manual intervention.
