SPL Channel One Channel Strip

SPL is mainly known for the development of highly specialized audio-tools. Our philosophy, ”one product for one task”, is aimed at fast and simple operation in conjunction with high processing quality, to ensure highest musical performance. With Channel One SPL have produced a complete channel strip which for the greater part is based on the processing concepts already successfully realized in other products. The very complex task of a channel strip profits particularly from the innovative techniques that have always allowed the operation of SPL equipment to be efficient and objective. The ususal recording day is to a high degree determined by a series of opposing time limits – the ”highly paid” singer/speaker desires a quick recording; however, if technical preparation takes a long time because of unsuitable equipment, time will be lost, increasing the costs and souring the working environment. The Channel One in all cases however allows fast production without any loss of professional precision and diligence. The Channel One consists of a transistor/tube pre-amplifier with microphone-, line- and instrumental inputs, a de-esser, a compressor/limiter with noise gate, an equalizer (EQ) section and a headphone monitor.

Principles The Channel One has all necessary tools on board to prepare a recording for a digital recording system. It offers many possibilities for sound processing – the total bandwidth of subtle corrections to low-fidelity sounds is available. The versatility and completeness of the unit permits its use in additional areas, over and above the purely ”recording channel” facility, for instance in mixdown, as high quality single outboard EQ or compressor. To maximize user friendliness and for clarity all modules have been reduced to the most important regulating and switching facilities. Fast and effective operation is in no way impeded, quite the opposite – it´s supported. More time remains to work creatively. Great value was placed from the outset on high flexibility. An example of this is the 3 separate inputs for microphone, line-signals or instruments, each of which has been optimized to its function. A twin triode tube is utilized in the process at 2 points – one immediately after the amplifier stage and the other at the end of the chain, so that the processed signal passes once again through the tube stage. This construction combines the advantages of the transistor pre-amplifier stage (high performance with minimal distortions and low noise levels) with the improved musical expression of the tone produced by tubes. The microphone input can be optionally provided with Lundahl input transformers. The input transformers deliver a five times enhanced microphone level to the pre-amplifier, an amplification which reduces the equivalent load to the electronic pre-amplifier. The balanced outputs can also be equipped with Lundahl transformers, which deliver an even warmer and fuller sound.
