Who it fits

Key specs explained for ZED-24

16 Mic, 16 Line/Inst, 2 Stereo inputs

This mixer offers 16 microphone inputs and 16 line or instrument inputs, plus two stereo channels. You can connect numerous microphones for live vocals or instruments while also handling stereo sources like keyboards or playback devices. This high channel count suits complex live setups where many sources need individual control, unlike smaller DJ controllers that offer limited input options.

DuoPre XLR Microphone preamps with up to 69dB gain

The preamps provide up to 69dB of gain, ensuring quiet microphones are amplified clearly without noise. This high gain range handles demanding microphones effectively. You benefit from clean signal capture across various mic types. This feature is critical for live sound engineers who need reliable amplification, whereas basic DJ gear often lacks dedicated high-gain mic preamps for professional vocal use.

100Hz High Pass Filter on every mono input

Each mono channel includes a high-pass filter that removes low frequencies below 100Hz. This cleans up muddy audio by cutting rumble or unnecessary bass from vocals and instruments. You get clearer mixes by eliminating frequency clashes. This practical tool helps manage stage noise, a feature rarely found on standard DJ controllers which typically focus on mixing rather than detailed input filtering.

Class compliant USB I/O

The USB connection is class compliant, meaning it works with Mac, Windows, and many mobile devices without installing drivers. You can record the main mix or route stereo returns easily. This plug-and-play simplicity reduces setup time and compatibility issues. It offers flexibility for recording or streaming, providing a direct digital interface that many traditional DJ controllers do not match in terms of driver-free operation.

25.4 inches height, 18.3 inches length, 23.1 pounds weight

The unit measures 25.4 inches tall and 18.3 inches long, weighing 23.1 pounds. This size indicates a robust, full-sized rack-mountable or desk-top mixer. You need adequate space for this footprint during transport or setup. The weight suggests durability for touring. Unlike compact DJ controllers, this physical size accommodates more controls and connections, requiring a dedicated space in your gear layout.

Build Quality and Physical Design

According to the listing, the Allen & Heath ZED-24 is a touring-quality mixer. The chassis measures 18.3 inches in length and 25.4 inches in height. The depth is 3.9 inches. The unit weighs 23.1 pounds. It is finished in grey with red accents. This build suggests it is designed for transport and stage use. The weight indicates a sturdy internal construction that can handle frequent movement.

The layout supports 24 channels of input. You have 16 microphone inputs and 16 line or instrument inputs. There are also two stereo inputs. The controls include DuoPre XLR microphone preamps. These provide 48V phantom power and up to 69dB of gain. Each preamp uses two gain stages. This design aims for accurate sound across the entire gain range. It handles gain-hungry microphones well.

The mixer includes a 100Hz high-pass filter on every mono input. This removes unneeded low frequencies. The three-band MusiQ EQ features a swept mid-frequency. You can cut or boost highs and lows with shelving EQ. Insert sockets are available on every mono channel and the main mix. These allow connection of external processors. The USB connection is class compliant. It does not require drivers for Mac, Windows, or mobile devices. This design simplifies setup for recording or streaming.

Setup and Everyday Use

Setting up the Allen & Heath ZED-24 involves connecting your audio sources to its 16 microphone preamps and 16 line or instrument inputs. Each mono channel features DuoPre XLR preamps with 48V phantom power, allowing you to use condenser microphones directly. The preamps provide up to 69dB of gain, which handles high-output microphones without distortion. You can also engage the 100Hz high-pass filter on every mono input to remove low-frequency rumble before it reaches the mix.

For daily use, the 3-band MusiQ EQ lets you sculpt tones with a swept mid-frequency selection. This helps you target specific ranges for vocals or guitars. Two pre-fade auxiliary outputs let you send independent mixes to monitor speakers. Two post-fade auxiliary outputs send signal levels that follow the main mix, which is useful for external effects or recording feeds. Every mono channel and the main mix have insert sockets for external processors like compressors.

The USB connection is class compliant, meaning you do not need to install drivers on Mac, Windows, or mobile devices. You can record the main mix or individual channels and route stereo audio back into the mixer. The unit weighs 23.1 pounds and measures 18.3 by 25.4 by 3.9 inches, making it stable for touring or studio use. The grey and red finish matches standard rack equipment aesthetics.

Before You Buy ZED-24 Mixer

You should verify your venue’s power requirements before purchasing. This unit weighs 23.1 pounds, so ensure your flight case or rack can support the load. The USB connection is class compliant, meaning you likely do not need to install drivers on Mac or Windows systems. However, you must check if your mobile devices support USB audio out, as compatibility varies. You will need XLR cables for microphones and TRS cables for line inputs. Keep the DuoPre preamps clean by using dust covers when not in use. This mixer suits setups requiring extensive analog routing. If you need digital integration or lightweight portability, other options in this 2026 guide may fit better. The ZED-24 is built for touring durability. You should also consider if you need external processing, as insert points are available for compressors. This gear fits best in permanent or semi-permanent installations where channel count matters more than size.

Check before you buy

• Verify USB audio compatibility with your mobile devices.
• Ensure your rack or case supports 23.1 pounds.
• Check if you need external compressors for insert points.
• Confirm venue power outlets match the mixer’s needs.
