Description
Quested SM748 Overview
The SM748 from Quested is a four-in, eight-out digital crossover. With high-performance 24-bit digital converters and digital signal processing, the unit is able to capture and output program material with a high degree of accuracy. The converters run at 96kHz, a rate that yields a bandwidth of over 30kHz and a dynamic range in excess of 116dB.
The SM748 features up to nine parametric sections on each band. Parametric sections can be reconfigured to provide alternate filter shapes, including an array of filters inclusive of phase adjustment in two-degree steps. Each output also features a combination of limiters, one that protect against driver over-excursion, and a second look-ahead limiter for additional safety.
Standard AES/EBU interfaces are built-in, allowing the unit to work with both digital inputs and digital output streams. Sample rate converters are included on the inputs, allowing the SM748 to accept digital audio with sample rates anywhere from 32kHz up to 192kHz. Output sample rate is fixed at 96kHz.
