• INTRODUCTION
The STX2848 is a digital audio processor that offers an enormous variety of high accuracy settings and configurations for improving your
audio system's performance. It is composed of two DSP's (Digital Sound Processors) that provide real-time equalizing, filtering, balancing,
gain, phase inversion, limiting, and digital output and input routing among other treatments.
• OVERVIEW:
1 - (+ BAT): For the positive charging source, connect the terminal to the positive pole of the battery (+12 V) using, at minimum, a cable with
a gauge of 2.5 mm² (AWG 13). Use of an external protection fuse (1A) is highly recommended.
2 - GND: The negative (ground) must be connected to the vehicle chassis by a cable with a gauge of at least 2.5 mm².
3 - REM : Automatic activation may be connected to the output of the power antenna for the CD/DVD/MP3 player via 0.5 mm² gauge cable
(AWG 20).
4 - DISPLAY: LCD display.
5 - ENCODER: navigation interface, settings adjustment, "Enter" (quick press), "Return" (hold).
6 - HOTKEYS : Quick press will pull up shortcut keys configuring output channels when changing settings. HOLD will turn specific output
channels on or off. Blue light - channel output on. Red light - channel output off.
7 - LEDS LIMITER: The LEDs will light when the "Limiter" of the channel in question is acting, they are also used as indicators of output
saturation.
8 - INPUTS: Individual A and B inputs.
9 - OUTPUTS: 1 to 8 individual outputs.
10 - MAXIMUM LEDS INPUT SIGNAL: The LEDs will light indicating that the respective input signal has reached the maximum level allowed.
• BEFORE INSTALLING
Read this manual carefully before installing the STX2848 digital audio processor. The instructions for installation and connections must be
followed precisely. If necessary, contact our Customer Service.
All battery connections (power feed), inputs and outputs can be set up easily and safely using the power and RCA connectors.
The STX2848's auto turn on signal should be the same as that of the amplifiers or it should be sequenced as follows:
STX2848 switches on first, then STX2848 switches off after the amplifiers.
1) To avoid damaging the cables, make sure that they are not installed across sharp metal edges.
2) Keep all cables as far as possible from the ignition, ignition cables and electronic fuel injection modules, since they may cause sound
interference.
3) Keep the length of RCA cables as short as possible. It is best to use long power cords and decrease the length of RCA cables.
(We recommend triple-shielded RCA cables STETSOM).
•RESOURCES
The STX2848 has 2 independent inputs and 8 outputs, and the following functions:
• Graphic input equalizer (15 bands and equalization presets);
• Parametric input equalizer (frequency, gain, Q factor);
• Parametric equalizer per output (frequency, gain, Q factor);
• Routing between inputs and outputs;
• High precision crossover with Butterworth and Linkwitz-Riley filters and attenuations up to 48 dB / 8th;
• High precision alignment / delay;
• Phase inversion;
• Limiter with Threshould, Attack and Release adjustment;
• Independent gain and mute per output and master volume;
• Working memory with automatic saving of settings;
• Allows you to save and load the settings made by the user;
• Security password to block parameter modification;
• Frequency generator, frequency sweep and pink noise generator;
• Screen saver with rotating text.
NAVIGATION AND CONTROL
Navigation and control of the STX2848 are made via the "ENCODER" knob and the "HOTKEYS" hotkeys.

• GRAPHIC INPUT EQUALIZER
The input graphic equalizer has 15 bands, allowing a variation of ± 12 dB per band, with a pitch of 0.1 dB, with frequencies equally spaced
in 2/3 octave, in the range of 25 to 16 kHz in accordance with ISO requirements . The graphic equalizer acts on the two inputs simultaneously.
GRAPHIC EQ
f: 63 Hz +2.6 dB
The STX2848 comes with 12 graphic equalizer presets: FLAT, LOUDNESS, BASS BOOST, MID BASS, TREBLE BOOST, POWERFUL, ELECTRONIC,
ROCK, HIP HOP, VOCAL, POP, and PANCADAO (heavy beat). These can be found under the "Graph EQ Presets" menu on the main screen.

• PARAMETRIC EQUALIZER
The parametric equalizer allows you to choose a gain / attenuation at a specific frequency, as well as the bandwidth of that equalizer by means
of the Q factor, the smaller the Q the greater the width of that equalization band, affecting to a greater extent the neighboring frequencies .
The STX2848 has 9 parametric equalizers distributed as follows, 1 for the inputs and 8 for the outputs (1 for output).
