...h wireless tablet software or the new, patent-pending, front-panel Portal metering and control interface.

The basic platform offers complete, native-digital signal-processing functionality, with support for up to four-in by twelve-out for loudspeaker applications and eight-in by eight-out for EQ applications. The signal processing can also be changed to provide an EQ four-by-four together with a loudspeaker two-by-six configuration.

The Lake Processor includes several advance technologies for improving sound quality. These include Raised Cosine Equalization (the foundation underlying the revolutionary Ideal Graphic EQ™ and Lake Mesa EQ interfaces), plus linear phase crossovers, LimiterMax™ loudspeaker protection, and Iso-Float Ground Isolation.

Four slots provide additional configurability, for adding analog I/O and other capabilities via expansion cards. We offer the Lake Processor in five preconfigured versions. Converter cards can be easily added at any time, in the shop or in the field, to meet changing needs.

Input and Output Processors

Input/output processors are used for multichannel sound recording in real time. Capable of studio-grade fidelity, these specialized soundcards are used in professional sound engineering and make use of an audio stream input output protocol. These kinds of I/O audio processor soundcards are fitted with multiple input and output connections, usually USB, FireWire or some kind of optical interface so that a larger amount of data can be carried than with a normal sound card. Input/output processors also emphasize higher fidelity and sampling rates, as they are intended for real-time audio mixing and multi-channel recording. Due to their highly specialized nature, input/output processors are not considered practical for home users, as they lack certain features common in consumer soundcards, such as real-time ambience effects, environmental audio extensions and the ability to accelerate hardware in video games, as these are considered to be undesirable. Input/output processors feature a specially designed protocol that is capable of handling numerous inputs and outputs for audio, as consumer soundcards have a sampling latency that is comparatively large, and therefore unsuitable for professional applications. Consumer soundcards simply take too long to convert and transfer a sound sample to the hard drive of a computer, and they are also limited in the amount of bit depths and effective sampling rates they can process. Input/output processors typically have multiple channels, rather than just the two provided on most consumer soundcards, and there connectors are more accessible.
