L2 Ultramaximizer

Classic look-ahead brickwall peak limiter and level maximizer

Maximize Levels with Immaculate Impact

With its legendary combination of look-ahead brickwall peak limiting, level maximization, and ultra-high resolution, the L2 has become a mainstay in mastering and mixing chains in studios everywhere. And for delivering mastered audio, the advanced output dithering algorithms and noise shaping make it easier than ever to convert audio to lower bit depths.

Engineered for mastering, with a stereo-only format, the L2’s ease of use, sonic clarity, optimized release times, effective peak limiting, and streamlined user interface are in a class by themselves.

Stereo-only format optimized for bus applications
Look-ahead gives overshoot-free response and fast attack
48-bit, double-precision math for superior noise-shaping accuracy
Fast workflow, with simplified control set and dithering options
ARC (Auto-Release Control) responds sensitively to dynamics
Choose between Manual and ARC™ Automatic Release Control
Low latency for live sound and for tracking
IDR™ Increased Digital Resolution with double precision bit re-quantization and dithering

Achieve Maximum Mastering Levels
With Clarity, Accuracy, and Transparency

Effortless Workflow
Optimization for bus applications simplifies the control set to Threshold, Output Ceiling, Release, and dither settings. Control the peaks with Ceiling, and raise the output level with Threshold. Simple—and it gets the job done.
The Secret of Shaping
The L2’s superior noise shaping comes from 48-bit, double-precision, ninth-order noise-shaping algorithms. Choose Moderate, Normal, or Ultra to suit program material from delicate acoustic sounds to hard rock.
High-Resolution Ready
With more studios using 32-bit and higher file resolutions, conversion to standard 24-bit files is now as important as 16-bit conversion was to CDs. For older digital formats, the L2 also converts to 20- and 22-bit files.
