Pegasus DSP-Tuning
Seminar 2025
Hands-on Training · Authorised Dealers
Precision You Can Hear
In 12 October 2025, ASL Car Audio Sdn Bhd hosted the Pegasus DSP-Tuning Seminar — a hands-on workshop dedicated to digital signal processing and in-car sound calibration. Dealers and installers moved between classroom fundamentals and live tuning practice in real vehicles, working directly with Pegasus amplifiers and processors under trainer guidance.
The day was built around one idea: a DSP is only as good as the hands tuning it. Correct gain structure, time alignment, and EQ decisions are what turn a correctly wired system into one that actually sounds right.
Presented alongside Hector Lee of JFF Autoworks — a judge for IASCA, MECA, EMMA, SQC, MACE and CAN, with over 20 years of installation and tuning experience shared with attendees on the day.
Every attendee left with a reference in hand. ASL Car Audio’s own DSP Tuning Handbook was distributed on the day — a printed companion for the tuning sheets and notes participants filled in during hands-on practice.
DSP Fundamentals
Digital crossovers, time alignment, and parametric EQ — taught against real tuning scenarios, not just slides.
Live In-Car Tuning
Trainers ran tuning software live from demo vehicles, adjusting channels and correction curves in real time.
Hands-On Practice
Every participant took the driver’s seat for guided, one-on-one tuning practice with trainer support.
01 · CROSSOVER
Crossover Filters
Setting each speaker’s frequency range so highs, mids, and bass blend cleanly.
02 · TIME ALIGNMENT
Time Alignment
Correcting for speaker distance so sound arrives at the ear together.
03 · PHASE
Phase
Keeping every driver working in harmony instead of cancelling each other out.
04 · EQ
EQ & Q Factor
Fine-tuning tone so the system sounds natural, not harsh or boomy.
05 · CHANNELS
Channel Configuration
Matching 6, 8, or 10-channel DSP setups to each vehicle’s speaker layout.






More Than a Certificate
Every attendee walked away with more than notes — a Certificate of Completion that stands as Pegasus’s formal recognition of hands-on DSP-tuning competency.
