( Brand: Symetrix ), ( Model: 564E ), ( Effect/enhancement: Noise Gating/expansion )
The 564e Symetrix 4-Channel Gate is a versatile and powerful audio processing device designed for professional audio applications. This 1U rack-mountable unit offers four independent channels of audio gating, each equipped with a comprehensive set of features to facilitate precise and effective control over dynamic range.
Each channel features a high-quality analog-to-digital converter (A/D) and digital-to-analog converter (D/A) for crystal-clear audio output, as well as a variable attack time ranging from 10 milliseconds to 2 seconds, adjustable release time from 10 milliseconds to 10 seconds, and threshold level adjustment with a range of -80 dB to 20 dB. The 564e also includes a hold function, which allows the gate to remain open for a specified duration after the audio signal drops below the threshold, and a side-chain high-pass filter to eliminate low-frequency noise from the side-chain.
In addition to its gating capabilities, the 564e also offers a compressor/limiter mode, which allows you to apply dynamic range control using a variety of compression algorithms, including VCA, optical, and FET. This mode includes adjustable attack, release, ratio, threshold, and gain reduction parameters, as well as a bypass function to compare the processed and unprocessed signals.
The 564e Symetrix 4-Channel Gate is equipped with a user-friendly front panel with LED indicators for each channel, as well as a full complement of input and output connectors, including balanced XLR and unbalanced 1/4" TRS jacks. The unit also features a MIDI input and output for remote control and automation, as well as a USB port for firmware updates and configuration backup.
Overall, the 564e Symetrix 4-Channel Gate is a powerful and versatile audio processing device that offers a wide range of dynamic control options for professional audio applications, from music production and live sound to broadcast and post-production. Its high-quality audio processing and extensive feature set make it an ideal choice for any audio engineer looking to achieve precise and effective dynamic control in their work.
