ZVL and DSP Guide

Setting Up a ZVL or DSP with Strapable Non-DD Amplifiers

Properly configuring a ZVL or DSP with half-bridge amplifiers can improve signal consistency and tuning control. Follow this guide to integrate your system efficiently.

Understanding ZVL vs. DSP

ZVL: Active RCA distribution with gain control, useful for keeping multiple amplifiers in sync.

DSP: Full control over crossover points, phase, time alignment, and per-channel tuning.

Wiring a ZVL to Non-DD Amplifiers (Unstrapped)

  • Connect the ZVL power and ground to the same source as the amplifiers.
  • Run RCAs from the head unit to the ZVL input.
  • Run ZVL RCA outputs to each amplifier's RCA input.
  • Ensure all amplifiers have their gain settings matched.

Using Slave Mode for Better Control
More Info

Setting amplifiers to Slave Mode allows the ZVL to bypass the internal input stage of the amps, preventing gain mismatches and ensuring a uniform signal.

Wiring a DSP for Per-Amp Control

  • Connect the DSP to the head unit via RCA.
  • Run each DSP output to its respective amplifier.
  • Assign specific crossovers, gain levels, and time alignment per channel.

Final Calibration Steps
More Info

  • Set gain levels on the ZVL or DSP carefully.
  • Use an oscilloscope or distortion detector to avoid clipping.
  • Match crossover points across all amplifiers.
