The Mackie 2404VLZ4 is a comprehensive 24-channel professional live sound and recording mixer that combines a robust analog signal path with modern digital connectivity. It builds on the acclaimed VLZ4 platform, featuring Mackie's UltraMic preamps known for their high headroom, low noise, and transparency across all 12 mono input channels. The mixer's intuitive 4-bus architecture provides flexible routing for subgroups, auxiliary sends, and main outputs, making it suitable for complex live mixes, broadcast applications, and multi-track recording sessions. Its steel-reinforced chassis ensures durability for both studio use and mobile applications, while the logical control layout allows engineers to work efficiently under pressure, with critical functions like 3-band EQ with sweepable mids, high-pass filters, and dedicated channel inserts readily accessible.

The channel strip configuration is designed for maximum versatility, comprising 12 mono mic/line channels, 4 stereo line channels, and dedicated stereo tape returns. Each channel features four auxiliary sends—two pre-fader for monitor mixes and two post-fader for effects—along with comprehensive routing options to the four subgroups or directly to the main stereo bus. The mixer includes a dedicated stereo multi-effects processor with 16 editable presets, accessible via dedicated send and return controls, eliminating the need for external effects units in many scenarios. A highlight is the integrated USB audio interface, which provides 2-in/2-out connectivity to a computer at 24-bit/96kHz resolution, enabling straightforward stereo recording of the main mix or playback of digital audio sources directly into the console.

Completing its professional feature set are balanced XLR main outputs, control room and studio monitor outputs, dual headphone amps, and a dedicated talkback section with a front-panel microphone input. The inclusion of a 2-track input for playback and a comprehensive solo system with PFL and AFL functionality ensures this mixer can handle the demands of live sound reinforcement, studio production, and streaming broadcasts. By merging high-quality analog mixing, built-in digital effects, and computer connectivity in a single, reliable package, the Mackie 2404VLZ4 serves as a powerful and adaptable centerpiece for a wide range of professional audio environments.
