Stetsom STX2448 Digital Automotive Digital Audio Processor

The Stetsom STX2448 is a digital automotive audio processor designed to enhance your audio system with a wide range of high-precision adjustments and configurations. It features a Digital Signal Processor (DSP) that performs real-time equalizations, crossover filters, alignment, gain control, phase inversion, limiter, and digital routing of inputs and outputs.

This processor offers 2 audio inputs (A and B) and 4 independent outputs, allowing you to select the audio source (A, B, or A+B) for each output. It includes an integrated equalization system with a 15-band graphic equalizer, offering manual tuning or 12 preset options (Flat, Loudness, Bass Boost, Mid Bass, Treble Boost, Powerful, Electronic, Rock, Hip Hop, Pop, Vocal, and Pancadão). For professional adjustments, it provides 5 parametric equalizers with gain control, specific frequency settings, and adjustable equalizer bandwidth.

The Crossover function allows precise definition of cut frequencies, attenuation rates, and filter topologies (LowPass and HighPass) using Butterworth and Linkwitz-Riley filters (12/18/24/36/48 dB/8ª). To protect amplifiers and loudspeakers, the STX2448 incorporates a Limiter with a Dynamic Attack-Release system, which dynamically controls attack and release parameters in real-time, ensuring security and sound fidelity. Additional audio treatment capabilities include High Accuracy Delay, Phase Inversion, Independent Gain by Output, and Master Level control.

For accurate measurements and adjustments, the STX2448 has an integrated Audio Generator with tone generation and frequency sweep. It also includes management functions such as saving and loading settings, a security password to block parameter editing, a Marquee/Text Display, and language selection (English, Spanish, Portuguese).
