Burl Audio B32 Vancouver

The Burl Audio B32 Vancouver is a high-headroom 32 channel analog summing mixer engineered to bring console grade depth, stereo width, and harmonic cohesion to digital mix setups. Featuring discrete Class-A signal path with custom BX5 output transformers and a switchable gain boost circuit, the B32 combines the precise imaging of modern summing with the rich, saturated warmth of a vintage analog desk.

The B32 offers switchable transformer architecture via the BX5 button. Keep it disengaged for pristine, direct-coupled Class-A transparency, or engage the custom BX5 nickel/iron-core output transformers to introduce smooth harmonic saturation, low-end punch, and high-frequency glue.

To handle hot multi-channel stems coming out of D/A converters without clipping, the B32 features a +6 dB Gain Boost switch. Engaging the boost allows you to drive the stereo mix bus harder into the BX5 transformers or downstream processors, saturating transients and enhancing depth without altering your DAW's mix automation.

Key Features

• 32 Analog Inputs via DB25: Accepts 32 discrete balanced inputs across four rear-panel DB25 connectors for seamless routing from multi-channel converters.

• Discrete Class-A Circuitry: Zero-capacitor, direct-coupled transistor topology delivers wide frequency response and transient speed.

• Switchable BX5 Output Transformers: Instantly switch between clean direct output and rich transformer harmonic saturation.

• +6 dB Gain Boost Switch: Pushes the mix bus harder into transformers to add analog glue and weight.

• Stepped Output Attenuators: Independent 0.1 dB stepped rotary attenuators for precise left/right master level trim.

• Dual Stereo Outputs: Two pairs of stereo XLR outputs for simultaneous routing to print converters and monitoring setups.

• 1U Rackmount Chassis: Heavy-duty steel construction built in the USA for continuous commercial studio workflows.
