The Weiss A1 is a high-fidelity microphone and line preamplifier designed to provide pristine, natural sound in any recording situation. Featuring Lundahl transformers on both the input and output stages, the A1 ensures exceptionally low noise, minimal distortion, and an extended frequency response, making it ideal for critical studio applications.
At its core, the Weiss A1 employs a discrete Class A preamplifier with a current-feedback architecture, delivering up to 60dB of clean gain while maintaining signal integrity. This design allows for ultra-low distortion and a wide bandwidth, ensuring transparency and accuracy across all microphone types.
A key feature of the A1 is its digitally controlled de-esser, designed to offer smooth and natural sibilance reduction in vocal recordings. Using a multiplying D/A converter operating at a 500kHz sample rate, the de-esser provides highly precise control with significantly lower noise than conventional designs. This functionality can also be applied to line-level signals, making it a valuable tool for taming sibilance in existing recordings.
The Weiss A1 includes a -24dB pad for handling line-level sources, along with a selectable low-cut filter at 40Hz or 80Hz to manage low-frequency build-up. Its 48V phantom power ensures compatibility with condenser microphones, delivering a stable and clean power supply. For stereo applications, two Weiss A1 units can be linked via a side-chain to enable seamless de-essing across both channels.
Designed for seamless integration into professional setups, the A1 is compatible with API’s 500-series rack systems. Built with high-quality components and a robust construction, it upholds Weiss Engineering’s reputation for precision and reliability.
The Weiss A1 is a premium preamplifier that combines exceptional analogue design with innovative digital control, making it an essential tool for capturing recordings with absolute clarity and precision.
