Product details

Overview

The Timpano TPT-SP4BT is a compact digital signal processor that connects via Bluetooth to your phone or tablet. It is designed to improve both aftermarket systems and factory radios, offering a tuned, cleaner sound without a full head-unit swap.

Smart, remote control at your fingertips

Control and fine‑tune performance through the TIMPANO app on Android or iOS. Make real‑time adjustments to EQ, crossover filters, routing, and gain as you listen to different tracks or drive environments. A built‑in voltmeter helps you monitor the electrical health of your system while you’re on the road, and a remote relay enables straightforward integration with other components.

The DSP also includes practical testing tools such as a frequency generator, frequency sweep, and pink noise to help you verify response and behavior across the audible spectrum.

Sequencer for effortless multi‑component management

The exclusive SEQUENCER feature lets you configure startup and shutdown sequences for up to three connected devices (S1, S2, and S3) from remote connections. This can simplify wiring and help ensure a smoother power‑up routine for your upgraded audio setup.

What you can expect from the DSP toolset

  • Real‑time equalization, time alignment, and phase control for precise imaging
  • Adaptive crossover filters and per‑channel gain for balanced sound
  • Phase inversion, limiter, and flexible input/output routing for clean signal flow
  • Diagnostic and test tools including a battery voltmeter, frequency generator, frequency sweep, and pink noise

Real‑world use cases

  • Dial in clarity and imaging for daily commutes and longer drives
  • Tailor tonal balance to your car’s acoustics and seating position
  • Coordinate power and signal flow when upgrading to multiple amplifiers or subwoofers

Designed for flexibility and ease of use, the TPT-SP4BT is a practical tool for enthusiasts who want to explore tuning options. Individual results vary with vehicle, equipment, and listening preferences, so the app gives you a path to explore possibilities rather than a guaranteed outcome.
