DBX131SV vs DBXDI1 — Compare
dbx 131s Single 31-Band Graphic Equalizer vs dbx Di1 Active Direct Box
The dbx 131s is a 31-band graphic equalizer for surgical frequency shaping across the entire spectrum, while the dbx Di1 is an active direct box for instrument-to-console signal conditioning. Choose the 131s if you need to sculpt room acoustics or mix multiple sources; choose the Di1 if you need transparent, transparent impedance matching and tone shaping for a single instrument.
No sales tax on orders shipped outside California — total cost beats national retailers that charge sales tax in nearly every state.

Frequently asked questions
Can the Di1 replace the 131s in a live sound setup?
No. The Di1 is a direct box for one instrument; the 131s is a graphic EQ for the main mix or group bus. They serve different purposes—the Di1 patches between an instrument and console, while the 131s processes an entire audio signal chain.
Which one shapes tone?
Both do, but differently. The Di1 applies transparent, subtle tone shaping and impedance matching to a single instrument. The 131s offers surgical, band-by-band equalization across the full frequency spectrum for mixing, correction, and reinforcement.
Is the 131s overkill for home recording?
Not necessarily. If you record multiple instruments or need to correct room acoustics, the 31 bands offer precision. For simple instrument-to-interface connections, the Di1 is more practical and affordable.
Do I need both?
In a typical live or studio chain, yes. Use the Di1 at the source (instrument to console input) and the 131s on the main output or venue system (to shape the complete mix and correct room response).
