• The Allen & Heath CQ-18T is a compact 18-channel digital mixer designed for live sound, streaming, installations, and portable productions. It combines Allen & Heath’s renowned processing quality with a modern, intuitive interface.
• At its heart is a 96 kHz FPGA engine, delivering ultra-low latency (under 0.7 ms) with pristine audio quality. It’s equipped with 16 mic/line inputs, a stereo line input, plus Bluetooth connectivity, all controlled via a responsive 7” touchscreen and convenient rotary encoders.
• For ease of use, the CQ-18T introduces smart tools like:
  • Gain Assistant, which sets preamp levels automatically and avoids clipping,
  • Feedback Assistant, which quickly identifies and suppresses feedback with dynamic notch filters, and an Automatic Mic Mixer (AMM), perfect for panel discussions and speech-heavy events.
• Its flexible outputs (main XLR plus six configurable monitor outs) make it ideal for performers and engineers alike, while built-in Wi-Fi means you can control everything from your phone or tablet using the CQ MixPad app — no external router needed.
• With multitrack recording to SD card or direct USB streaming, four powerful FX engines, and compact portability (~3 kg), the CQ-18T packs professional-grade mixing into a friendly, versatile format.
