Allen & Heath CQ-18T Ultra-Compact 18-in/8-out Digital Mixer

Allen & Heath CQ-18T: Ultra-Compact 96kHz Digital Mixing for Fast Shows

System snapshot: The Allen & Heath CQ-18T is an ultra-compact 18-in/8-out digital mixer built for gigging bands, rehearsal spaces, home recording and streaming, speech applications, and corporate AV. It pairs a tactile desktop surface with built-in Wi-Fi control, assistive setup tools, and multiple recording/playback paths so you can go from patch to polished mix without burning soundcheck time.

Mixing workflow that adapts to the operator: CQ lets you choose how deep you want to go on every channel. Use Quick Channels when speed matters and you want application-specific processing that comes together fast, or switch to Complete Channels when you want deeper, parameter-by-parameter control for a more surgical mix.

Processing and effects without the price-and-size penalty: CQ brings high-quality onboard processing and a refined FX suite into a small footprint. The goal is simple: clean gain structure, controlled dynamics, confident vocal clarity, and effects that enhance a performance instead of washing it out.

Integration and capture-ready design: With multitrack options via USB and SD, plus straightforward playback options for walk-in music and intermission content, CQ-18T supports modern gigs where recording, streaming, and corporate deliverables are part of the job, not an afterthought.

Real-World Applications and Sound Roles:

• Gigging bands: 6 monitor mixes plus Main L/R, fast gain setup, and feedback control for tight stages.
• Mobile DJs and event pros: Multi-mic management, reliable playback, and venue-wide control from a phone or tablet over built-in Wi-Fi.
• Corporate AV and speech: Automatic Mic Mixer workflows for panel-style clarity and reduced background wash.
• Streaming and home recording: Multitrack capture for post-production and repeatable show templates.

Where the Allen & Heath CQ-18T Excels

• Fast Channel Build-Out: Quick Channels speed up dial-in for common sources, while Complete Channels let engineers go deep when the room demands precision.
• Smarter Gain Staging: Gain Assistant accelerates multi-channel setup and keeps levels under control through the performance to reduce surprise peaks.
• Feedback Control You Can Trust: Feedback Assistant targets problem frequencies per output so monitors and speech rigs stay stable under real venue conditions.
• Hands-On Touch + Muscle Memory: A 7-inch touchscreen, rotary control, and assignable hardware controls keep the operator moving quickly during transitions and cue-heavy shows.
• Recording That Matches Modern Gigs: Multitrack workflows via USB and SD support capture, virtual soundcheck style prep, and post-mix deliverables.
• Event-Ready Output Count: Main L/R plus 6 monitor outputs keeps small-to-mid stages flexible without extra distribution hardware.
• Playback Options for Real Rooms: Dedicated playback paths help with walk-in, breaks, intros, and corporate stings without hijacking your live channels.
• Built for Chicago Turnovers: Optimized for fast ballroom load-ins, tight stage plots, and mobile rigs that need stable control and repeatable results.

Control Modes for the Allen & Heath CQ-18T

Front-panel workflow (hardware control): CQ-18T is designed for hands-on mixing with rapid navigation between core screens, plus tactile controls that reduce menu diving. The 7-inch capacitive touchscreen supports direct fader moves and parameter control, paired with a touchscreen rotary for fine adjustments. Three assignable Soft Keys can be set for show-critical functions like tap tempo, mutes, scene control, or recording actions, and CQ-18T adds three Smart Rotaries that can follow the active screen to control the most relevant parameters without hunting through layers.

Channel operation modes: Each input channel can be run as a Quick Channel or a Complete Channel. Quick Channels prioritize speed with instrument/application-focused processing, while Complete Channels provide deeper parameter access for detailed shaping when the room, mic choice, or stage volume needs more exact control.

Output processing and stability tools: CQ-18T supports output EQ workflows (GEQ/PEQ options) and includes Feedback Assistant behavior designed to detect feedback and apply narrow filters, helping protect monitor mixes and speech systems in reflective rooms. This is particularly useful when the venue changes night to night and you need a repeatable path to stability.

Group control for busy shows: Use DCAs and Mute Groups to control multiple channels at once, enabling clean transitions (walk-in music to mic, band changeovers, panel to Q&A) without losing your internal balance.

Inside the CQ-18T Workflow: Assist Tools, Capture Paths, and Live Control

Quick Channels vs Complete Channels: Speed When You Need It, Depth When You Want It

CQ-18T is built around the reality that not every operator wants the same workflow at every gig. Quick Channels help you assemble a usable, musical channel fast using application-specific processing, which is ideal for short changeovers, rehearsal rooms, and mobile rigs. When a room is tricky or the stage is loud, switch a channel to Complete to access deeper controls and tune the mix with more precision.

• Use Quick for: rapid soundcheck, basic voice reinforcement, and consistent starting points across venues.
• Use Complete for: surgical EQ decisions, tighter dynamics control, and nuanced FX balance.

Gain Assistant: Faster Setups with More Predictable Headroom

Setting gain across multiple channels is where time disappears in real-world setups. Gain Assistant is designed to get you to an optimal level quickly across one or multiple inputs, and then continue monitoring so performance dynamics do not turn into unpleasant surprises. For bands, this means more time on monitor balance. For corporate and speech, it means more consistent intelligibility from mic to mic.

Field advantage: quicker patch-to-performance, cleaner gain structure, and fewer last-minute fader rescues.

Feedback Assistant on Outputs: Confidence for Monitors and Speech Systems

Feedback is rarely a single-frequency problem, especially in reflective rooms and low-stage-volume corporate environments where mic placement changes constantly. CQ-18T includes Feedback Assistant behavior that detects feedback and applies narrow filters per output so you can keep monitor mixes usable and keep speech reinforcement stable without chasing rings all night.

• Best use: stage monitors, lectern mics, panel mics, and any situation where the room fights back.
• Practical result: fewer emergency EQ sweeps and more repeatable stability across venues.

Pristine 96kHz Audio + Onboard Processing: Small Footprint, Serious Results

CQ-18T draws on Allen & Heath live console technology to deliver high-quality audio at 96kHz with studio-grade processing and an optimized FX suite. The core goal is clarity without harshness: defined vocal presence, controlled low end, and a mix that translates from rehearsal to venue to recording.

Why it matters to DJs and event pros: speech stays articulate, playback stays clean, and you can move between segments (music, mic, program audio) without your mix falling apart.

Built-In FX + FX Assist: Effects That Enhance Instead of Taking Over

CQ introduces a user-friendly suite of reverb, delay, and modulation algorithms with instrument-specific presets designed to speed up setup. FX Assist is intended to shape effects so they support the source instead of swallowing it, which is especially useful when multiple performers share the same space and you need clarity more than wash.

Live payoff: quicker effect decisions, less time tweaking, and more consistent mixes across gigs.

Recording & Playback Options: Capture, Stream, and Deliver

CQ-18T supports multiple ways to record and play back audio so you are not boxed into one workflow. Use the USB audio interface for DAW-based multitrack recording and streaming, record multitrack to SD for reliable on-the-go capture, and handle stereo record/playback via USB key. Bluetooth playback allows quick phone-based program audio when you need walk-in music or break content without rerouting your live channels.

• Bands: multitrack capture for post-mix and rehearsal review.
• Corporate AV: reliable playback and clean capture for deliverables.
• Mobile DJs: fast program playback options plus separate mic workflows.

Integrated Dual-Band Wi-Fi: Venue-Wide Control Without Extra Hardware

CQ-18T includes integrated dual-band Wi-Fi so you can control the mix from anywhere in the venue using the CQ MixPad app. For rooms with changing crowd density, this matters: you can walk the coverage area, adjust vocal presence, tighten monitors, and confirm playback levels without being tethered to FOH.

Deployment note: treating Wi-Fi control as part of the soundcheck plan improves consistency for mobile rigs and fast-turn events.

I/O Built for Real Gigs: 16 Mic/Line + Stereo In, Main L/R + 6 Monitor Outs

CQ-18T provides the connectivity needed for band and event work: 16 mic/line inputs plus a stereo line input, Main L/R outputs, and six monitor outputs for individual mixes. Two assignable headphone outputs allow separate monitoring paths, which is useful for portable production setups and recording checks without interrupting the main mix.

How to Deploy Allen & Heath CQ-18T in the Field

Deploy the CQ-18T like a system hub: start with a clear patch plan, define your outputs (Main L/R plus monitor mixes), then build the mix from gain structure outward. For gigging bands, prioritize monitor stability first, then refine FOH tone. For corporate AV and speech, prioritize clean mic gain, consistent level matching across speakers, and conservative output processing for feedback resilience.

• Stage-first setup: Patch inputs, run Gain Assistant across key sources, then balance monitors before chasing FOH polish.
• Monitor control: Treat the 6 monitor outputs as dedicated mixes; apply Feedback Assistant as needed to stabilize wedges or IEM sends in reflective rooms.
• Group strategy: Assign DCAs for drums/backline/vocals or speech mic groups, and configure Mute Groups for clean transitions (all stage mics, all podium mics, all playback).
• Venue tuning: Use app-based control to walk the room, verify intelligibility, and confirm playback level consistency from front row to back wall.
• Capture workflow: Decide pre-show whether the deliverable is SD multitrack, DAW multitrack over USB, or a simple stereo capture, and set that path before doors.

CQ-18T is built for real-world speed: stable gain, stable monitors, and venue-wide control that keeps changeovers clean.
