Black Lion Auteur Quad 2: Four Channels of Chicago-Style Character

The Black Lion Audio Auteur Quad 2 is a four-channel rackmount microphone preamp, delivering up to 66 dB of gain across four channels with analog VU metering on every channel. It packs four independent preamps into one rack space so you can track a drum kit, a small ensemble, or several sources at once. Each channel blends a fast, transparent input stage with a colorful transformer output, the design Black Lion calls Chicago-style. That combination makes it a flexible front end for almost any session.

How a Microphone Preamp Shapes Your Sound

A microphone preamp boosts the tiny signal from a mic up to a usable level before it reaches your interface or recorder. The quality of that first gain stage sets the tone, noise floor, and detail of everything you capture. The Auteur Quad 2 gives each of its four channels a dedicated gain stage, so no channel shares circuitry with another. Clean, independent gain means four sources stay distinct and quiet even when tracked together.

A Hybrid Input and Output Design

Each channel starts with a solid-state integrated-circuit input stage, an amplifier built on a compact chip rather than a large discrete board, chosen here for its fast and transparent response. The signal then passes through an American-made Cinemag output transformer, a wound component that adds gentle weight and harmonic color as it is driven. Keep the gain modest for a clean, honest capture, or push it for added heft on drums and vocals. This transparent input into a colorful output gives one preamp two distinct voices.

Inputs and Outputs for Every Source

The rear panel carries a balanced XLR input for each of the four channels, ready for your microphone collection. Every channel also has a front 1/4-inch input that accepts both instrument- and line-level signals, so guitars, basses, synths, and stereo mixes all have a home. On the output side you get both XLR and 1/4-inch TRS connections, feeding an interface, mixer, or converter. Balanced connections throughout keep hum and noise low across long studio cable runs.

Per-Channel Controls You Reach For

Independent 48V phantom power on every channel powers condenser microphones without affecting the other inputs. A -10 dB pad tames hot sources so the input stage stays clean, while a polarity reverse switch flips phase to fix cancellation between paired mics. Each control sits on its own channel strip, so adjustments stay fast and obvious during a busy tracking date. Nothing is shared, which keeps four very different sources easy to manage.

Analog Metering and a Road-Ready Build

A backlit analog VU meter on each channel shows how hard you are driving that preamp, helping you set level and gauge transformer color. VU metering reacts the way engineers expect, averaging the signal rather than chasing every peak. The chassis is brushed aluminum, built to survive both the studio and the road. Its rackmount format bolts cleanly into any standard 19-inch rack.

Where the Auteur Quad 2 Fits Your Studio

Project and commercial studios reach for the Auteur Quad 2 when one or two channels are not enough. Its four channels make quick work of a drum kit, a horn section, or a full band tracking live. Because each channel can lean clean or colorful, the same unit covers detailed acoustic work and aggressive rock sources. It serves as a dependable, great-sounding front end for interfaces that need better preamps than their built-in inputs.
