The QU‑32’s 32 AnalogiQ mic preamps deliver studio‑grade performance․ Each channel has 48‑V phantom power, a 60‑dB gain knob with 1‑dB resolution, a 1/4‑inch pad for 20‑dB attenuation, and a 3‑band EQ (low, mid, high)․ The preamps offer low noise, high input impedance, and a 20‑dB pad for loud sources․ Channel strips include dedicated gain, frequency, and Q controls․ Routing is flexible: channels can be sent to any of the 32 main outputs, group buses, or the matrix mix․ The console stores all channel settings, allowing instant recall of 32 channel configurations․ The preamps support automatic phantom‑power‑sensitive mode, disabling phantom when a dynamic mic is detected․ All parameters are saved in internal memory, preserving gain, pad, EQ, and routing across power cycles․ The QU‑32 combines high‑quality analog preamps, flexible routing, and comprehensive recall, making it a powerful tool for live sound reinforcement and studio recording․ The console’s 32‑channel recall system allows operators to instantly switch between different mic setups, making it ideal for events with multiple performers․ Additionally, the QU‑32’s USB 32×32 interface records all channels directly to a computer, providing high‑resolution multitrack files for post‑production․ Its rugged chassis and intuitive layout make it suitable for touring rigs, while the built‑in AMM handles up to 16 microphones without additional gear․ With its recall, flexible routing, and analog preamps, the QU‑32 remains a staple for studio and live use !!
Routing and Matrix
The QU‑32 offers flexible routing with 32 inputs to 32 outputs, 8 group buses, and a 32‑channel matrix․ Each channel can be sent to any mix bus or matrix slot․ Matrix mixes are adjustable via faders, and the console supports bypassing for routing ․ All settings are recallable!․
Group, Matrix Mixes, and Bypass Options
The QU‑32 provides eight group buses that can receive any of the 32 input channels․ Each group has its own fader, pan, and EQ, and the routing matrix allows independent level control․ The 32×32 matrix section expands flexibility by routing any input to any output․ This is ideal for complex live or studio setups, enabling sub‑mixes, monitor mixes, or feeding external processors․ Each matrix channel has a dedicated fader, pan, and mute control, and the routing can be saved and recalled with the console’s memory system․
Bypass options are available for both group and matrix mixes․ The bypass switch on each group bus allows the user to route the input signals directly to the main mix, effectively disabling the group mix․ Similarly, each matrix channel can be bypassed, sending the original input signal to the output instead of the matrix mix․ The console also supports a global bypass that disables all group and matrix routing, sending all channel signals straight to the main mix․
When using bypass, remember the console’s internal processing applies channel‑level effects like compression or EQ, even when a group or matrix is bypassed․ This keeps the signal path consistent and avoids unexpected changes․ The bypass switches are on the front panel and show status on the LCD․ Operators can program bypass behavior into preset memory for switching during a live event․ The combination of group, matrix, and bypass makes the QU‑32 a powerful tool for live sound reinforcement and studio recording, offering flexibility without compromising ease of use․ —all set․ Done
