Product Description
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.

Title: You must read this
Review: For those of you that take the time to read honest reviews. I’m not being paid to say this by any means. No cash no product no promise just me spreading the word if you take your car auto serious and you don’t have one of these sorry to say you must still be listening to 8 track tapes. I’ve tested it on 5 totally different systems from a 250 dollar one to a 2000 dollar one retail that is by the way, it made everyone of them from like a average of on a 1 thru 10 scale a 9 some 10 some 8, 9 and most started at a 4 . The thing makes your bass HIT!!! Like your high end so clear. Down side no instructions in English. I’ve had mine now for 8 months and I’m still learning new things it can do. If your on a budget but you have to have that sound you think you deserve that don’t have the money for the big dollar product buy one of these don’t be dumb by 1 you can’t go wrong

Title: Amazing unit for $115
Review: So you’re asking yourself “it’s $115 and from Brazil. Is it junk?” That’s what I was thinking but for only $115 I figured WTH and got it. This thing is awesome! Yes, I had to go to youtube to figure some of it out but its not that much to learn. I am very happy with the options and everything works great. Sequencer is great to stop that THUMP when your start your system. Routing by channels is great. So much ability to fine tune EQ, gain, a limiter to protect speakers that need absolute cutoff frequencies, crossovers with digital reading for precise crossover points (instead of the endless game turning the AMP dials for voltage changes).I could not be happier with this unit.Have to add a comment on a previous 1 star review on here that said “no left or right”. Ok you have to apply a little common sense using a DSP. There’s 2 input channels on the $119 one. Coming off your RCA leads from an LC2 probably or your radio if you somehow found a head unit with low volt outputs and those will be left and right channel. Now you have 4 channels OUT on the DSP. You also set in the setup system what input goes to what output. So for output you plug left on channel 1, right on channel 2, left on channel 3 and right on channel 4 toward your 4 channel AMP. In the setup screen go to “Routing” and assign outputs matching what I stated here. A DSP is not for newbs with no common sense of signaling in car audio. You have to think through your setup. If yo have no left or right YOU did not set it up correctly.

Title: Great Starter/Weird DSP
Review: Features are great for the price. Anything more than 2way active systems will want sometime different.The system is perfect for:-2-Channel Source (Bluetooth Adapter)-Woofer + Mid/Tweet Systems-Great starter DSP!PRO:# of Features. Price point!Built in tools are rare, useful, and well implemented.2way Active Crossover options are vast. You can setup a band pass output channel, but you run out of channels for a stereo 3way setup.Quick output muting via buttons.All settings via 1 rotary wheel! Navigation generally great.Small size.Save and RecallDocumentation is very well written.Display is beautiful and clear.Cons/Weirdness:2 channels routable to pairs of MONO channels. There is no routing input pair L AND R to Output Pairs. Your only routing options are: both left, both right, or summed L and R to a pair of outputs. The workaround is to route L to a pair and R to another pair leaving an unused RCA in each. I suspect they can call it a 8 channel DSP even though it is only a 2inputx4output unit.I suspect the reason for weird is it shares all the same chassis with the 2×8 device.Spinning the rotary wheel to adjust frequency from 20-20k will drive the user crazy. Soooo slowâ¦. Fortunately we donât need to do this often. UghhhhhTHERE IS NO PINK NOISE tool in the 2×8 unit. Only sweep and sine generator. I was disappointed in that false advertisement.Why so many remote sequence outputs?! 1 is enough.1 band of parametric per output pair is very limited. 1 for the pair of units is also not enough for most.Why EQ presets?!Crossover is high, low, and band pass. Outputs to yield 3 way active setups of hard to see with a single unit. The routing problem could work with a subwoofer on a separate device leaving this unit to provide midbass, mid/tweeter setup.What a weird little DSP gem. New to audio DSP? This is a fun and ultimately useful device. I donât hate it. Buy 2 if you need complexity, or they 2×8 Unit. 😉

Review: It drastically changed my systems sound for the better. If I can now figure out how to fine tune the DSP

Title: Works well.
Review: I have this to control my door speakers (2 -ds18 pro series 6×9 and 2- ds18 6.5 pro series). The dsp helps a lot because I kept my stock head unit.

Title: Amazing
Review: Does 100% what it says. For the cost this is a steal! I only used it for the 100% accurate 100% digital crossovers but it can do way more. My sound system sounds way better with this!
