Setting Up The Pioneer DEH-80PRS Head Unit with 3-way Crossover Network and Time Alignment Delay

In this detailed walkthrough, Chris Adams explains how to manually set up the Pioneer DEH-80PRS in three-way network mode with full time alignment, crossover tuning, and EQ adjustment. He demonstrates how to measure speaker distances, align mids and tweeters using phase cancellation, tune subwoofers (including stereo subs), and use crossover slope and EQ to shape staging and tonal balance. The focus is on setting everything by ear using mono reference material, sweep tones, and careful incremental adjustments to achieve a centered image and a windshield-height soundstage. ⸻ TABLE OF CONTENTS 00:00 – Introduction: Why the DEH-80PRS Is Still Special in 2026 00:52 – Overview of Features: 3-Way Network, 6-Channel Time Alignment, 15-Band EQ 01:45 – Manual vs Auto Setup: Why Tune by Ear 02:41 – Switching to Network Mode (Rear/Front/Sub → 3-Way Active) 04:13 – Understanding Time Alignment: Distance vs Delay Explained 05:27 – How Small Delay Changes Affect Phase and Imaging 06:33 – Baseline Setup: Start Flat, Disable Loudness & Processing 07:20 – System Overview: Focal 3-Way, Eminence Woofers, Stereo Subs 10:39 – Tools Needed: Measuring Tape, Mono Music, Tone Generator 12:21 – Music Selection Strategy for Accurate Tuning 15:22 – Measure Speaker Distances & Set Initial Values 16:07 – Step 1: Time Align Midrange to Center Using Mono Source 19:44 – Choosing Your Center Image Position (Windshield Staging) 20:33 – Muting Bands to Isolate Midrange 22:54 – Step 2: Align Tweeters to Midrange Using Phase Cancellation 24:04 – Reversing Phase & Maximizing Crossover Overlap 27:49 – Finding the “Thinnest” Sound to Identify Perfect Alignment 30:56 – Repeat for Opposite Side Tweeter 31:07 – Fine-Tuning Image Height & Eliminating Smear 33:36 – Rechecking Mono Center After High Alignment 35:03 – Step 3: Time Aligning the Subwoofer 37:06 – Tradeoffs of Stereo vs Mono Subwoofers 39:43 – Hidden Subwoofer Menu (Network 4 Settings) 42:49 – Using Long Delays to “Pull” Bass Forward 44:02 – Setting Proper Sub Level (Turn Down Until It Disappears) 46:24 – Crossover Fundamentals: LPF, HPF, Bandpass Explained 48:07 – Recommended Starting Points (80 Hz / 2.5 kHz) 49:54 – How Crossover Slope Affects Phase & Stage Height 51:38 – Adjusting Crossovers in Network Menu 53:41 – Using Crossover Overlap to Raise Soundstage 55:42 – Step 4: EQ – Corrective First, Taste Second 57:49 – Using Sweep Tones to Find Frequency Problems 59:44 – Left/Right Independent EQ Adjustments 01:01:03 – Cutting Frequencies to Reduce Smear 01:02:30 – Final Tonal Adjustments (Bass/Mid/Treble Levels) 01:04:07 – Final Thoughts: Time Investment & Long-Term Tweaking 01:05:28 – Why This Head Unit Is Still Worth Buying Used
