Audio mixer Mackie 1604VLZ4 — 16-channel mixer, 20–20,000 Hz, 92 dB SNR, 10 kΩ line input

Mackie 1604VLZ4 is a 16-channel analog audio mixer engineered for both live sound and studio environments. The console covers a 20–20,000 Hz frequency range and offers a line signal-to-noise ratio of 92 dB, delivering clear audio with low background noise. Inputs include microphone preamps and line-level inputs with a nominal input impedance of 10 kΩ for line sources and 2.5 kΩ for microphone sources. The mixer features Mackie's Onyx-designed mic preamps and a high-headroom, low-noise analog path housed in a robust chassis. Typical power consumption is 50 W and the unit measures 440 × 443 × 129 mm.

Advantages

The 1604VLZ4 combines high-headroom Onyx-style mic preamps with a low-noise signal path to preserve dynamic range and clarity across channels. Its 16-channel layout provides flexible routing and mixing options for small to medium setups, while the rugged construction ensures durability for regular transport and stage use. Balanced inputs and clear frequency response make it suitable for combining multiple microphones and line sources without introducing excessive noise or distortion.

Suitable for

• Live band front-of-house for small to medium venues
• Rehearsal rooms and project studios
• Podcasting or streaming setups with multiple mic and line sources
• Stage monitoring and small PA systems

How to use

Place the mixer on a stable surface or rack shelf and connect mains power per local electrical requirements. Connect microphones and line-level sources to their respective inputs, observing correct gain staging: set input trim so peaks do not clip while maintaining adequate level for the channel EQ and bus routing. Use the channel EQ and aux sends to tailor tone and create monitor mixes. Route outputs to main PA, monitors or recording interfaces as required, and monitor levels using the mixer's level indicators and meters. Power down the unit before connecting or disconnecting powered speakers to avoid loud transients.

Usage recommendations

For best noise performance and headroom, set mic preamp gain conservatively and use outboard compressors or limiters only when necessary. Keep cable runs balanced where possible and group similar sources on nearby channels to simplify monitoring and equalization during live shows or recording sessions.
