Used Art DUAL MP Pro Sound Effect

ART Dual MP — Two-Channel Tube Microphone Preamp

Take your recordings to the next level with the ART Dual MP, a hybrid tube/solid-state microphone preamp built for clarity, warmth, and flexibility. This rack-mount unit features two independent channels, each with its own input and output controls, +20 dB gain boost switch, phantom power, and phase reversal. A four-stage “sonic character” LED array gives you visual feedback of the tube’s behavior — from clean through warm to gentle saturation — letting you dial in the perfect tone.

On the connectivity side, you get balanced XLR and unbalanced ¼″ inputs and outputs, front-panel instrument/line jacks for quick access, and a robust steel chassis ready for studio or stage. With >100 dB dynamic range, ultra-low noise, and a frequency response spanning 10 Hz to 20 kHz (±1 dB), this unit performs impeccably across vocals, instruments, and DI applications. Whether you want pristine transparency or a touch of tube coloration, the Dual MP delivers professional tone in a compact 1U format.

✅ Item Condition & Testing

All used gear is fully tested when it comes into our shop and again before shipping, so you can buy with confidence. Any included accessories will be shown in the photos, and if there are any functional issues, they’ll always be noted in the listing. Since these are used items, you can expect normal cosmetic wear that doesn’t always show up clearly in pictures. Everything we sell is also available to try in-store, so a little extra demo wear may be present.

? Shipping Info

We ship to the contiguous 48 states with flat-rate pricing that usually covers the maximum cost (including insurance). If the shipping looks high, send us your ZIP and we’ll get you a more accurate estimate. Orders outside the lower 48 may require additional processing and shipping costs — please reach out before ordering.

Some larger or fragile items (like big amps, drum kits, or cabs) may not have a shipping option listed because they’re safest for local pickup. If you’re not sure, just contact us and we’ll confirm if it can be shipped.
