Description
Product Overview
Fine-tune a multi-amplifier car audio system with the Stetsom STX 2448 DSP, a 2-input, 4-output digital signal processor. Its LCD controls, flexible crossover options, equalizers, limiter, and REM sequencer bring key tuning and system-control functions into one unit.
Use its four independent outputs to shape processed audio for multiple amplifiers or zones. The front-panel encoder and hotkeys let you adjust settings directly on the processor.
Key Features & Benefits
- Flexible equalization: A 15-band graphic EQ and input/output parametric EQs give you broad tonal shaping and frequency-specific adjustments.
- Selectable crossovers: Choose Butterworth or Linkwitz-Riley slopes to set frequency separation for your system.
- Output routing: Assign input A, B, or A+B to each output to suit your signal layout.
- Time alignment: Apply up to 8 ms of alignment to help coordinate speaker timing.
- Signal management: Configure the limiter’s threshold, attack, and release, and adjust master level and output gain.
- System control: The REM sequencer can activate other devices, while saved settings and password protection help manage your configuration.

Why Choose This Product?
The STX 2448 combines signal routing, crossover setup, equalization, time alignment, and limiting in one processor. That range of controls is useful when you want to tailor separate outputs instead of relying on a single shared signal adjustment.
Its 12 graphic EQ presets offer starting curves for different listening targets, while the parametric controls allow more focused tuning. Save and load settings with Autosave and five slots for repeatable configurations.
Installation & Compatibility Notes
Plan for RCA connections from inputs A and B and RCA outputs to the rest of your signal chain. The processor requires a 9 V ~ 16 V DC supply, with GND and +BAT connections and a recommended external 1 A fuse.
REM IN auto-activates amplifiers with the head unit, and the sequencer provides up to 180 mA per output for activating other devices via REM. Confirm that your system’s connections, power supply, and REM requirements match these specifications before installation.
Frequently Asked Questions
How many inputs and outputs does the STX 2448 have?
It has two inputs, A and B, and four outputs. Each output can be routed from A, B, or A+B.
Which crossover types and slopes can I select?
It offers Butterworth and Linkwitz-Riley crossovers, each with 12/18/24/36/48 dB/8ª slopes.
What does the time-alignment range allow?
Alignment is adjustable from 0 ~ 8 ms (275 cm), allowing timing adjustments across the processor’s outputs.
