Processor Crossover Stx2448 Floating Wire and RCA Input This product has been carefully developed by a team passionate about audio and technology, aiming to deliver an experience of excellence and quality. Explore all the adjustment and audio equalization features so that you can fully enjoy your music with high fidelity sound. Features The processor has 2 input channels (A and B) and 4 independent output channels (1, 2, 3, and 4), as follows: Inputs: Main In: RCA Connection (A and B) High In: Wire Connection (A and B) Outputs: Out 1: RCA (L + R) Out 2: RCA (L + R) Out 3: RCA (L + R) Out 4: RCA (L + R) Input Connections: High Connection (Wire): Common in vehicle's original radios and players. RCA Connection (LINE): Common in aftermarket radios and sound equipment. The digital processing features allow precise audio adjustments through various integrated functions and features: DSP FLOAT MODE, provides different flows and resources; INPUT GAIN; GRAPHIC INPUT EQUALIZER; SUBHARMONIC bass; OUTPUT MODE, allows flexibility of features in each output; PARAMETRIC OUTPUT EQUALIZERS; ROUTING between inputs and outputs; High precision CROSSOVER (with Butterworth, Linkwitz-Riley, and Bessel filters); High precision DELAY; PHASE INVERSION; RMS and PEAK LIMITER with adjustable Threshold, Attack, Hold, and Release; MASTER VOLUME, GAIN, and MUTE for each output; AUTOMATIC SAVE and LOAD to save and load audio parameters; SECURITY PASSWORD to lock parameter modifications; FREQUENCY GENERATOR and sweep; Integrated SEQUENCER for remote activation with configurable time. DSP FLOAT MODE The DSP Floating feature allows the processor to be loaded with different audio flows and resources, increasing the range of possibilities for configuring various systems. Available modes are: STD: Input Gain, 15-band Graphic EQ, Graphic Equalizer Presets, Parametric Output Equalizers, Routing, Crossover, Delay/Alignment, Phase Inversion, RMS Limiter, Output Gain, and Mute. PRO: Input Gain, Sub Harmonic Bass, Parametric Output Equalizers, Routing, Crossover, Delay/Alignment, Phase Inversion, Peak Limiter, RMS Limiter, Output Gain, and Mute. Some other Functions: OUTPUT MODE This feature allows for flexible distribution of processing resources as needed for each audio output. This feature allows selecting the operating mode for each output, varying the number of parametric equalizers and the maximum attenuations of the crossover filters. ALIGNMENT (DELAY) Align the transducers (speakers) digitally through time correction in the DSP, ensuring that sounds from all speakers reach the listener simultaneously, avoiding frequency cancellation and improving sound fidelity. OUTPUT GAIN Adjust the individual gains on the outputs within the range of -45dB to +15dB, with 1dB steps and a general volume range of 0 to 100dB. Technical Specifications: Number of input channels: 2 Number of output channels: 4 Input gain: IN A: 120dB / IN B: 212dB Graphic equalizer: 15 Bands: Gain 12dB, customizable and 12 presets Subharmonic BASS: Frequency: 20Hz - 120Hz and adjustable gain 24 Frequency: 10Hz - 22KHz Output parametric equalizer: Gain 12dB and Q Factor = 0.4 to 10.0 Routing of inputs to outputs: A, B, or A+B HPF LPE Crossover: Butterworth: 12/18/24/30/36/42/48 dB/octave Linkwitz-Riley: 12/18/24/30/36/42/48 dB/octave Bessel: 12/18/24/30/36/42/48 dB/octave Alignment/Delay: 0 ms to 8 ms (275 cm) Phase inversion: 0º - 180º Peak Limiter: Threshold, Hold, and Release RMS Limiter: Threshold, Attack, Hold, and Release Output gain: Master Level: 0% to 100% and gain: -45dB to +15dB Memory: Automatic save + 3 memory positions Security: 4-digit security password Frequency generator / sweep: 10Hz - 22KHz and adjustable gain Screen protection: Editable text (up to 15 characters) Languages: Portuguese, English, and Spanish Latency: 1.08ms Input impedance: 10K Ohms Output impedance: 47 Ohms Max. input voltage: 2V RMS / 5.6 Vpp / +8.2 dBu Max. output voltage: 2V RMS / 5.6 Vpp / +8.2 dBu Max.
