Bringing innovation and technology to the Automotive Sound market, STETSOM launches the STX2448 Automotive Digital Audio Processor, capable of making various adjustments, from filters, graphic and parametric equalization, alignment, phase inversion, limiter, audio generator, among others. Enhancing your audio system!

Through an LCD display and an intuitive interface, it allows real-time audio adjustments.

The STX2448 features 2 audio inputs (A and B) and 4 independent outputs and allows you to choose the audio source (A, B, or A + B) for each output.

It has an integrated Equalization system, with Graphic Equalizer of 15 bands of manual adjustment or by means of 12 Presets (Flat, Loudness, Bass Boost, Mid Bass, Treble Boost. Powerful, Electronic, Rock, Hip Hop, Pop, Vocal and Pancadão).For professional equalization adjustments, it has 5 Parametric Equalizers with gain control, specific frequency definition, and equalizer bandwidth. Allowing fine adjustments and detailed control of equalization.

The Crossover function makes it possible to precisely define the cutoff frequencies, attenuation rates, and topology of the LowPass and HighPass filters, with Butterworth and Linkwitz-Riley filters (12/18/24/36/48 dB / 8th).

To assist in the protection of amplifiers and speakers, the STX2448 has a Limiter with a “Dynamic Attack-Release” system that dynamically controls the parameters of Attack and Release in real-time, providing security and sound fidelity.

In the audio treatment, it also has Alignment features through High Precision Delay, Phase Inversion, Independent gain per output, and Master Level.

For accurate measurements and adjustments, the STX2448 has an integrated Audio Generator, with tone generation and frequency sweeping.

It also has the functions of management, Saves and Load Settings in memory, Security Password that blocks the editing of parameters, Marquee / Display Text, and Language Selection.
