You have decided to use a tool of high performance which sets you in the position to have faster success and a better sound quality in your music productions and pre-masterings. As a typical SPL unit the SPECTRALIZER combines exemplary specifications and high manufacturing standard with excellent sound quality to provide you a precious component for studio and mastering purposes. Please read this manual carefully to ensure you have all the information you need to use the SPECTRALIZER. We wish you every success with the SPECTRALIZER. Your SOUND PERFORMANCE LAB-Team I would like to start with my thanks to all our staff, who created what is to be described here. Special thanks go to Jorg Houpert, Klaus-Peter Webersinke and Andreas Skabe from Spectral Design, as well as Harald Obenland from Octum electronics. The importance of their exceptional qualification and talents cannot be overestimated. Our products are often tested and compared in many publications and by our customers themselfs and constantly valued with best results. I would like to pass on this broad appreciation to those, who deserve it – my excellent colleagues. Hermann Gier Contents Foreword Thanks Spectralizer Introduction Re-synthesizing second and third harmonics separately Improving clarity, intelligibility and depth without introducing harshness Warm and smooth sounding harmonic re-synthesis Easy and intuitive operation SPL digital audio processors are designed in cooperation with Spectral Design of Bremen, Germany, who are responsible for the DSP programming. Concept: The SPECTRALIZER is the first digital harmonics processor employing a new process which allows you to re-synthesize second and third harmonics separately, and with full control over their amplitude. The SPECTRALIZER benefits from SPL's expertise in psycho-acoustic principles and is the ideal tool to improve the clarity, transparency and intelligibility of any signal in the digital domain. A single instrument or vocal gains better penetration within a mix, while complete mixes benefit from improved subjective loudness without a measurable change in levels. While developing the DSP-program, a strong emphasis was placed on achieving warm and smooth sounding harmonic resynthesis. The digital domain tends to be susceptible to “sharpness” at the HF end of the spectrum, which made the design of the SPECTRALIZER all the more demanding. The result is a tool able to increase brightness and detail without adding harshness or sounding fatiguing. In comparison to ostensibly similar analogue systems, the SPECTRALIZER does not produce any phase deterioration, nor introduce unmusical intermodulation products. Operation: The SPECTRALIZER is fitted with six encoder controls, and the actual parameters values are shown in the LCD window. INPUT GAIN sets the overall input level with gain adjustment available from -20dB to +6dB, while the starting frequency for the re-synthesis of the harmonics is set using the FREQUENCY control. This functions as a high-pass filter adjustable over the range 1kHz to 7kHz in 500Hz steps; signals with a frequency lower than that selected using the FREQUENCY control remain unaffected. The DENSITY control offers a choice of six settings to determine the amplitude envelope of the added harmonics and works rather like a digital compressor to increase the density of the re-synthesized harmonics – which makes them more prominent. The 2ND and 3RD HARMONIC controls set the relative levels of the re-synthesized harmonics while the MIX control defines the balance between the new harmonics and the original signal. The SPECTRALIZER has three switch fu...
