MTX TL-88DSP 8-Channel Car Audio Digital Signal Processor Bluetooth Enabled DSP

The TL-88DSP is an 8-channel digital signal processor built around the ADAU1452 chip, giving you detailed control over equalization, crossovers, and time alignment in one compact unit. Tuning happens through Windows PC software, with day-to-day control from iOS and Android apps over Bluetooth, so you can set the system once on a laptop and switch presets later from your phone. Two EQ modes cover different skill levels. Basic mode gives 13 bands with fixed frequency and Q for quick adjustments, while Advanced mode opens 31 bands of parametric EQ with adjustable gain, frequency, and Q for precise correction of cabin acoustics. Crossover options include Butterworth, Linkwitz-Riley, and Bessel filter types with slopes of 12, 18, 24, or 48dB per octave, and time alignment adjusts up to 20ms to correct for unequal speaker distances. Six onboard preset slots store finished tunes, and presets save and load through the software, so a tune can move to another processor or serve as a starting point on a similar vehicle. Inputs accept high or low level signal up to 16V, and the 102mm by 98mm chassis mounts under a seat or behind a panel.
