Bringing innovation and technology to the automotive sound market, STETSOM launches the STX2848 Automotive digital audio processor, capable of making various adjustments, from filters, graphic and parametric equalization, alignment, phase reversal, limiter, audio generator, among others. Upgrade your audio system!
Through a LCD screen and an intuitive interface, it allows for real-time audio settings.
The STX2848 features 2 audio inputs (A and B) and 8 independent outputs, and allows you to choose the audio source (A, B, or A+B) for each output.
It has a built-in EQ system, with 15-band graphic equalizer, tuning manually or through 12 presets (Flat, Loudness, Bass Boost, Mid Bass, Treble Boost, Powerful, Electronic, Rock, Hip Hop, Pop, Vocal & Pancadão) .
For professional equalization settings, has 1 input parametric equalizer and 1 output parametric equalizer with gain control, specific frequency adjustment and EQ bandwidth. Allows fine tuning and detailed EQ control.
The Cross function allows you to accurately define the cutoff frequencies, attenuation rates, and topology of LowPass and HighPass filters with Butterworth and Linkwitz-Riley filters (12/18/24/36/48 dB / 8th).
To aid in protecting amplifiers and speakers, the STX2848 features a Limiter with dynamic attack release system which dynamically controls attack and release parameters in real time, providing sound security and fidelity.
On the audio processing, also has Alignment capabilities through high-precision delay, Pphase inversion, independent gain per output and master level.
For precise measurements and adjustments, the STX2848 features a built-in audio generator with tone generation and pink frequency and noise scanning.
Configuration copy function between output channels.
It also has the management functions, Save and load settings in memory, Security password that blocks editing parameters, Tent screen / text and Language selection (English, Spanish and Portuguese).
