Waves Ltd., the international leader in software and hardware based audio DSP, has announced the release of MaxxBCL, a new hardware unit that brings Waves’ unique bass enhancement and dynamics processing to live sound reinforcement for the first time.

MaxxBCL incorporates three of Waves’ well-known audio processors in a sturdy 2U rack-mount configuration: MaxxBass enhancer (which features a second-generation algorithm used in the company’s Renaissance Bass); Renaissance Compressor; and L2 Ultramaximizer limiter. All processing is performed in a 48-bit end-to-end path.

MaxxBass uses psychoacoustic principles to generate harmonics that add bass sound without adding bass frequencies, allowing the audience to hear bass lower than physically present. The dynamics of the original bass are duplicated in these harmonics, resulting in a very natural-sounding bass enhancement. The MaxxBass harmonics and the original bass can be mixed in any proportion at the output. Because MaxxBass can actually reduce low-frequency content while increasing bass sound, the result is improved amplifier efficiency, protection against blown speakers, and a bigger low end, all at the same time. Low-frequency feedback and rumble control are also improved.

The Renaissance Compressor provides the classic sound of analog compression, adding warmth and control to full mixes, vocals and instruments alike. Two compression modes are offered: ‘Opto’, which models a vintage optically driven compression system; and ‘Electro’, a modern-sounding compressor implementation. Full control of threshold, ratio and attack are included, along with Waves’ ARC™ (Automatic Release Control) that tailors the release time to the input signal, reacting in a way similar to the human ear, and dramatically increasing overall RMS level without sacrificing clarity or introducing artifacts.

The L2 Ultramaximizer limiter, heard on countless hit recordings and soundtracks, has a very fast overshoot-free response that puts the sound up-front with astonishing transparency. The brick wall limiting allows the engineer to set the actual peak level output desired and then set the threshold to make limiting and level rescaling a one-shot process. The L2 significantly increases the average signal level — and thus the perceived loudness, without introducing distortion or side effects.

The MaxxBCL’s front panel controls are designed for ease of use in performance conditions. For all processors, the top knob controls the parameter most likely to need riding during a live set: Intensity for MaxxBass, Ratio for Renaissance Compressor, and Out Ceiling for the L2 limiter. The backlit displays, meters and buttons are visible under any lighting, while the tactile-feel knobs offer sensory feedback. Dedicated bypass buttons for each processor are included.

Precision metering with re-settable peak hold options (90 dB range for I/O, 12 dB range for compressor and limiter attenuation) offer reliable readings. The peak holds for all meters can operate as momentary (2 sec) or infinite, and are reset by pressing the Peak button quickly.

MaxxBCL features analog (both balanced and unbalanced) and digital inputs and outputs, the latter including both AES-EBU and S/PDIF capabilities at sample rates up to 96 kHz. Independent input and output level matching is provided in six steps from 9 to 24 dBu, with 12 additional 1 dB steps of level trim per channel available on the front panel. The input trim rotary switch is based on 1% resistor networks. Transformer-coupled analog I/O (with Jensen transformers on the input) is provided and the unit features a dynamic range of 125 dB. Post-requantization processing is supplied by Waves’ IDR (Increased Digital Resolution) dither system, which includes 9th order noise shaping to minimize audible noise while dithering to 16- or 24-bit output.

MaxxBCL is built to stand the rigors of intensive touring, with reinforced construction, sturdy rack mounts, and handles that protect connectors and controls.

Waves MaxxBCL is now available with a U.S. MSRP of $3200.
