The Mackie 1604VLZ4 is a professional 16-channel compact mixer renowned for its robust build quality, transparent sound, and versatile routing capabilities, making it a staple in project studios, live sound, broadcast, and mobile production setups. This mixer is built around Mackie's acclaimed VLZ4 (Very Low Noise, Fourth Generation) analog circuitry, featuring the premium XDR2 microphone preamplifiers that deliver exceptionally clean gain with high headroom, ensuring pristine audio capture from a wide range of sources. Despite its compact rack-mountable footprint, the 1604VLZ4 incorporates a sophisticated 4-bus architecture, providing four separate sub-group outputs in addition to the main stereo mix. This allows for efficient mixing by grouping related channels—such as drums, backing vocals, or effects returns—for submixing, independent processing, or routing to multi-track recorders, a feature typically found on larger consoles.

The channel strip is comprehensively equipped, offering 3-band EQ with a sweepable mid-frequency for precise tonal shaping, along with high-pass filtering to eliminate unwanted low-end rumble. Each channel includes two auxiliary sends (one pre-fader, one post-fader) for creating monitor mixes or connecting external effects units. The mixer also features a dedicated stereo auxiliary return section with level and pan controls, allowing external processors to be seamlessly integrated into the main mix. For monitoring and cueing, the 1604VLZ4 provides a dedicated stereo control room/output section with multiple source selections and a powerful headphone amplifier, enabling accurate monitoring of the main mix, subgroups, aux returns, or tape inputs without affecting the main outputs.

Encased in a durable all-steel chassis, the mixer is designed to withstand the rigors of touring and daily use. Its intuitive layout, clear metering via 12-segment LED bargraphs, and comprehensive connectivity—including balanced XLR and 1/4" main outputs, direct outputs on the first eight channels, and RCA tape I/O—make it an incredibly flexible workhorse. The Mackie 1604VLZ4 successfully bridges the gap between compact size and professional functionality, offering musicians, sound engineers, and producers a reliable, high-performance mixing center that delivers the sonic integrity and routing flexibility needed for demanding audio production in a space-efficient package.
