Digital Signal Processor – 2 Input Channels – 8 Output Channels

Bringing innovation and technology to the Automotive Sound market, STETSOM launches the STX2848 Digital 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 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 an integrated equalization system, with 15-band graphic equalizer, manual tuning or through 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 1 INPUT Parametric Equalizer and 1 OUTPUT Parametric Equalizer with gain control, frequency specific setting and equalizer bandwidth. Allowing fine adjustments and detailed equalization control.

The Crossover function allows you to precisely define the cut frequencies, attenuation rates and topology of the LowPass and HighPass filters with Butterworth and Linkwitz-Riley filters (12/18/24/36/48 dB / 8ª).

To aid in the protection of amplifiers and loudspeakers, the STX2848 features a Limiter with Dynamic Attack-Release system that dynamically controls the Attack and Release parameters in real time, providing security and sound fidelity.

In the audio treatment, it also has Alignment capabilities through High Accuracy Delay, Phase Inversion, Independent Gain by Output and Master Level.

For accurate measurements and adjustments, the STX2848 features an integrated Audio Generator with tone generation and frequency sweep and Pink Noise.

Configuration Copy function between output channels.

It also has the functions of management, Save and Load Settings in memory, Security Password that blocks the editing of the parameters, Marquee / Text Display and Language Selection (English, Spanish and Portuguese).

  1. SEQUENCER: It allows sequencial activation of other products through the remote activation (REM) connection.
  2. REM IN: Allows automatic activation of the amplifier when turning on the radio/player.
  3. NEGATIVE POWER CONNECTOR (GND): Connect to the negative terminal of the battery.
  4. POSITIVE POWER CONNECTOR (+BAT): Connect to the positive terminal of the battery.
  5. DISPLAY LCD: It allows visualization and interaction with the processor system.
  6. ENCODER: Rotative control that allows interaction with the processor system functions and resources.
  7. HOTKEYS: Shortcut keys for selecting output channels.
  8. LED LIMITER: Indicates when the "LIMITER" of the channel in question is acting, and also to indicate output saturation. 
  9. LED MAX: Indicates that the respective input signal has reached the maximum level.
  10. AUDIO INPUT: RCA type connectors with independent actuation (A and B).
  11. AUDIO OUTPUT: RCA connectors, provide the audio processed.
