Allen & Heath AH-WZ414:4:2 MixWizard WZ4 – 14-Channel Desk/Rack Mixer for Commercial Installation

Product Overview

The Allen & Heath AH-WZ414:4:2 is the MixWizard WZ4 14:4:2—a professional 14-channel, 4-bus, 2-master analog mixing console engineered for permanent commercial AV installation, boardroom audio, government facilities, and fixed-installation sound reinforcement. Featuring 10 mic/line inputs with 48V phantom power, 4-band EQ with two swept midrange bands, six auxiliary sends, and tri-color 12-segment bargraph metering, the WZ4 provides the processing depth of a full-size console in a desk or rack-mountable form factor. The WZ414:4:2 is a direct choice for integrators deploying a fixed mixer in conference rooms, courtrooms, broadcast facilities, or houses of worship where proven Allen & Heath analog audio quality is required in a manageable channel count.

Product Description

The WZ4 14:4:2 provides 10 XLR/TRS mic/line combination inputs, each with Allen & Heath's professional mic preamp, 48V phantom power, 100mm fader, signal and peak LEDs, and 4-band EQ including two swept midrange bands. The semi-parametric mid EQ on each channel allows surgical frequency adjustment without external processing, a practical advantage in fixed installations where post-install room tuning is common.

The output section includes stereo and mono master outputs, four subgroup buses with individual faders, two matrix outputs, stereo control room/monitor outputs, and a stereo tape/record output—providing the routing flexibility required in broadcast, recording, and installed sound applications. Six auxiliary sends support monitor feeds, effects sends, and zone distribution. Ten direct outputs on the mono channels allow individual signal routing to recording systems or additional processing equipment.

Tri-color 12-segment bargraph metering provides accurate visual level indication across the output buses. The balanced XLR/TRS input architecture and professional +4 dBu operating level make the WZ4 compatible with standard commercial AV and broadcast signal chains. The desk or rack-mountable form factor allows installation in either a tabletop operator position or a standard 19-inch equipment rack.

Technical Specifications

Frequently Asked Questions

What does the 14:4:2 designation mean?

The designation describes the console's bus architecture: 14 input channels, 4 subgroup buses, and 2 master outputs (stereo left/right). This is a standard professional analog console configuration for routing flexibility.

Does the WZ414:4:2 have built-in effects or dynamics processing?

No. The WZ4 is a pure analog mixer without built-in effects engines or dynamics processing. External hardware processors can be inserted via the channel insert points on mono channels and the group insert points.

Can the WZ414:4:2 be rack mounted?

Yes. The WZ4 is designed for both desk operation and 19-inch rack installation. Rack mount ears are included or available to convert the console for rack use.

What is the direct output on each channel used for?

Each mono channel's direct output provides an individual feed of that channel's signal—useful for routing to a multi-track recorder, an additional mix system, or external dynamics processing without affecting the main mix.

How many headphone outputs does the WZ4 have?

The WZ4 includes one stereo headphone output for operator monitoring.

Is the WZ414:4:2 suitable for conference room or boardroom installation?

Yes. The WZ4's 14-channel capacity, 4-band EQ, six aux sends, and matrix outputs make it well-suited for fixed conference and boardroom audio systems where multiple microphone sources and multiple output zones are required.

Does phantom power affect all channels simultaneously?

The phantom power configuration depends on the specific channel grouping of the WZ4. Consult the product manual for the phantom power switching arrangement on this model.
