Gainlab Audio Lieutenant – Professional Monitor Controller and Studio Command Center

The Gainlab Audio Lieutenant is a unique analog monitor controller designed for professional recording studios that require full control over monitoring and signal distribution. This premium-class device combines the functions of a source selector, monitor controller, power sequencer, and talkback communication system. With four stereo inputs, three outputs for monitor pairs, and precise relay-based volume control, the Lieutenant becomes the true command center of any music production room.

Product Features

Relay-based volume control ensures exceptional precision in level setting with an accuracy of 0.1 dB, eliminating the noise and wear typical of mechanical potentiometers. The device offers four stereo inputs – two analog balanced, one digital S/PDIF/TOSLINK, and Bluetooth 5.4 – as well as three balanced stereo outputs for studio monitor pairs. Built-in Focus filters allow for the isolation and analysis of selected frequency ranges (low, mid, or high), while Pad, Mute, and automatic level trimming functions ensure smooth switching between speaker pairs without volume differences. An independent Cue loop with headphone output and an integrated talkback system facilitate communication in the studio, while the built-in power sequencer manages power in three independent zones.

Precision and Control – The Foundation of Professional Monitoring

The Gainlab Audio Lieutenant was designed to meet the demands of the most demanding music producers, sound engineers, and recording engineers. Relay-based volume control is a solution used in top-tier studio equipment – each mute step is precisely controlled, guaranteeing setting repeatability and signal purity. With a dynamic range of 118 dB and THD below 0.0007% at 1 kHz, the Lieutenant ensures transparent and faithful sound reproduction that introduces no distortion to the monitored material.

The Focus function is an incredibly useful tool in the mixing and mastering process. It allows for the isolation of low, mid, or high frequency bands, enabling the engineer to carefully analyze individual elements of the mix and make informed decisions regarding sound correction. Automatic output level trimming ensures that switching between different monitor pairs does not cause unpleasant volume jumps, which is particularly important when comparing sound across different speaker systems.

The built-in power sequencer is a feature that sets the Lieutenant apart from other monitor controllers. It allows for the management of the entire studio's power supply in three independent zones – they can be turned on and off manually or automatically, according to a programmed sequence. This protects equipment from power surges and simplifies daily studio work by eliminating the need to manually turn on each device individually.

Applications

• Studio monitor control – switching between three pairs of monitors with precise volume control and automatic level matching.
• Sound source management – selection among four sources (analog, digital, and Bluetooth) without the need to switch cables.
• Power sequencer – intelligent power management in three studio zones, manually or automatically.
• Talkback system and Cue loop – communication with musicians in the studio and independent headphone monitoring.
