Should I Use Equalizer, Crossover or Both?

🎛️ Boschmann Equalizer (EQX-75PRO)

Use when you need to fine‑tune sound quality.

• Adjusts tone balance across 7 frequency bands (bass, mids, treble).
• Ideal for car audio or small PA setups where you want clarity and control.
• Best for shaping sound after the source (radio, Bluetooth, mixer) but before amplification.
• Example: Matatu with 4 door speakers + subwoofer → EQ helps balance vocals vs bass.

🎚️ Audiobank Crossover (AAB-5DXi)

Use when you need to split frequencies to different speakers.

• Divides audio into subwoofer, mid‑woofer, bass mid‑high, treble, super tweeter.
• Prevents overlap and protects speakers from playing frequencies they can’t handle.
• Best for multi-driver setups (systems with subs, mids, tweeters all separate).
• Example: Mobile sound rig with subs, mids, tweeters → crossover ensures each driver gets the right signal.

🔗 Using Both Together

Use both when you want maximum control and protection.

• Signal flow:
  Source → Boschmann Equalizer → Audiobank Crossover → Amplifiers → Speakers/Subs
• EQ shapes the overall sound balance (tone control).
• Crossover ensures each speaker only plays its correct range.
• Perfect for professional setups (matatus, event rigs, mobile sound) where you need both clarity and speaker safety.
• Example: Event sound system → EQ for tuning to venue acoustics, crossover for routing subs/mids/highs.

⚡ Quick Decision Guide

• Small system (2–4 speakers, 1 sub) → Boschmann EQ only.
• Multi-driver system (subs, mids, tweeters) → Audiobank crossover only.
• Large or pro system (matatu, event rig, PA) → Use both EQ + crossover for best results.

🔗 Signal Flow: EQ + Crossover Setup

1. Source (Radio / CD / Bluetooth / Mixer)
   → Sends raw audio signal.
2. Boschmann EQX-75PRO Equalizer
   → Shapes the overall tone (bass, mids, treble).
   → Adjusts clarity and balance before splitting.
3. Audiobank AAB-5DXi Crossover
   → Splits the shaped signal into 5 bands:
   • Subwoofer (deep bass)
   • Mid-woofer (low mids)
   • Bass mid-high (upper bass)
   • Treble (highs)
   • Super tweeter (sparkle)
4. Amplifiers
   → Each band routed to its dedicated amplifier channel.
   → Example: mono amp for sub, 2-channel for mids, 4-channel for highs.
5. Speakers/Subs
   → Each driver receives only the frequencies it’s designed for.
   → Result: clean, powerful, distortion-free sound.

⚡ Why This Combo Works

• EQ = fine-tunes the character of the sound.
• Crossover = protects speakers and ensures accuracy.
• Together = professional-grade clarity + safety.
