What made Stetsom be recognized worldwide?

Stetsom won the SPL world record in the United States of America in 2007, becoming the first Brazilian car audio brand to accomplish this achievement.

Bringing innovation and technology to the Automotive Sound market, STETSOM launches the STX2448 Digital Signal 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 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 equalizer settings, it has 5 Parametric Equalizers with gain control, frequency specific setting and equalizer bandwidth. Allowing fine adjustments and detailed equalization control.

The Crossover function enables you to precisely define 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 STX2448 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 STX2448 has an integrated Audio Generator with tone generation and frequency sweep.

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, Portuguese)

Overview

SEQUENCER: It allows sequencial activation of other products through the remote activation (REM) connection.
REM IN: Allows automatic activation of the amplifier when turning on the radio/player.
NEGATIVE POWER CONNECTOR (GND): Connect to the negative terminal of the battery.
POSITIVE CONNECTOR (+BAT): Connect to the positive terminal of the battery. It is recommended to use a fuse for external protection of 1A.
DISPLAY LCD: It allows visualization and interaction with the processor system.
ENCODER: Rotative control that allows interaction with the processor system functions and resources.
HOTKEYS: Shortcut keys for selecting output channels.
LED LIMITER: The LEDs will light when the "LIMITER" of the channel in question is acting, they are also used as indicators of output saturation.
AUDIO INPUT: RCA type connectors with independent actuation (A and B).
AUDIO OUTPUT: RCA connectors, provide the audio processed according to the settings made on the processor.

Main Features


The SEQUENCER feature This feature allows you to activate several products sequentially. The sequencer has three outputs (S1, S2 and S3) that are activated and deactivated sequentially according to the input signal of the remote input (REM IN). The activation time interval between each output can be configured from 0s to 4s. It is possible to turn ON/OFF each sequencer output independently.	Navigation Keys Navigation and control of the STX2448 are made via the ENCODER knob and the HOTKEYS buttons.
