Channel One

SPL has a well-earned reputation for designing highly specialized audio processing tools, many of which exploit audiometric principles in order to achieve a more musical sound. Their philosophy is very much "one box for one task", and emphasis is placed upon a straightforward and manageable user interface, while often employing unique processing concepts.
The new SPL Channel One is a complete channel strip based largely on processing elements already developed and proven by SPL within their existing range of separate processors. It is envisaged that the unit will be of particular interest to those operating tape less studios. The target customers are computer based recording studios who are seeking a premium front end, though it is equally applicable to any demanding recording situation, whether digital or analogue.
Channel One incorporates a tube mic/line preamplifier, a de-esser, a compressor/limiter with noise gate, an special EQ-section and a headphone monitoring solution. In accordance with SPLs ease of use philosophy, Channel One features parameter automation in several areas to keep the number of knobs and switches to a minimum.
Channel One's tube mic preamp offers 48V phantom power, both pad and phase reverse switches, and may also be used as instrument tube preamplifier via a high impedance jack connector on the front panel. This is ideal for recording clean guitar, bass and electronic instruments.
The unique "one-knob" de-esser operates in auto-threshold mode and remains effective over an extremely wide range of input signal levels. Unlike conventional de-essers, it does not reduce the level of the entire signal during sibilant events, but instead affects only that part of the frequency spectrum affected by sibilance. This leads to a more transparent, natural sound with minimal side effects.
The compressor/limiter section utilizes SPLs Double-VCA-Drive providing outstanding dynamic performance without artifacts or negative side effects. This is a smooth and very versatile compressor that's simplicity to set up. Also incorporated is a noise gate with ARC-technology for vice-free gating.
Perhaps best known for their unique equalizer designs, SPL has devised a powerful equalizer section specifically for vocals and acoustic instruments: The Sound Performance Optimizer. It incorporates various EQ elements optimized to improve the power, impact, and intimacy of a voice, as well as a distortion control that can either subtly enhance or fully distort a vocal track.
To combat the latency problem of HD recording systems, Channel One is equipped with a headphone monitoring section and a phone plug on the front allowing the user to monitor the signal being recorded without it first having to make a round trip through the computer. This avoids delay or phasing problems.
As an option, Channel One can be equipped with a 24/96 AD-converter and Lundahl transformers are available for the analogue I/O stage offering an even smoother and classier sound.
