Triton Audio BigAmp Piezo｜Instrument Preamp Optimized for Piezo Pickups
Unleash the True Potential of Your Piezo Pickups
The Triton Audio BigAmp Piezo is a high-quality **instrument preamp** from Triton Audio, featuring a Class A JFET circuit design and offering an ultra-high **Input Impedance** of 5MΩ, optimized specifically for piezo pickups. This compact yet powerful device is directly powered by **Phantom Power**, transforming the weak, unbalanced signals from your acoustic guitar, violin, and other instruments into robust, full-bodied, low-noise balanced signals, making it the ultimate DI solution for studio and stage performances.
Compared to traditional **passive DI boxes** or standard preamps, the BigAmp Piezo specifically addresses issues like thin, brittle, and harsh tones caused by impedance mismatch in piezo pickups. It not only matches impedance but also actively boosts the signal through its built-in Class A amplification circuit, restoring the instrument's true, warm dynamics and details.
Quick Facts Product Overview
Brand: Triton Audio
Model: BigAmp Piezo
Product Type: Instrument Preamp / Active DI
Input Impedance: 5MΩ
Power Source: Phantom Power (+48V)
Applicable Scenarios: Acoustic guitar recording, violin/cello DI, ukulele performance, studio signal processing, any instrument using piezo pickups
適合誰購買
Musicians using acoustic guitars, violins, cellos, ukuleles, or other instruments equipped with piezo pickups, who wish to thoroughly improve their tone.
Studio engineers who need a high-quality, low-noise DI solution to record any acoustic instrument using piezo pickups.
Musicians who frequently perform in different venues, and want to achieve a stable and consistent instrument signal, avoiding thin or harsh live tones.
誰不適合購買
Musicians primarily using passive magnetic pickups (e.g., electric guitar/bass), for whom the standard BigAmp is more suitable.
Your mixer or audio interface does not support +48V Phantom Power.
Musicians looking for a DI box with tone-shaping features (e.g., EQ) (this product focuses on pure amplification).
Triton Audio BigAmp Piezo Core Technologies and Features
Class A JFET Circuit Design: Provides warm, transparent amplification, preserving the instrument's original tone, details, and dynamics, avoiding the sterile feel of traditional DIs.
5MΩ Ultra-High Input Impedance: Designed specifically for the extremely high output impedance of piezo pickups, perfectly solving fundamental issues like thin, brittle, and harsh tones caused by impedance mismatch.
Phantom Power Supply: No batteries or external power adapter required; it operates directly via the +48V Phantom Power from your mixer or audio interface, providing plug-and-play convenience.
Balanced XLR Output: Provides a low-noise, interference-resistant balanced signal, suitable for long-distance transmission to mixers or PA systems, ensuring pristine sound quality on stage and in the studio.
Robust Metal Casing: Designed for touring and frequent use, its compact size and sturdy construction can withstand various harsh environments.
Signal Solution Born for Piezo Pickups
The core value of BigAmp Piezo lies in its minimalist yet highly efficient signal processing capability. It focuses on solving the common problem of 'Impedance Mismatch' that occurs when piezo pickups are directly connected to low-impedance microphone preamps.
When piezo pickups are connected to an unsuitable input, the tone can sound thin, harsh, and lack low-end. BigAmp Piezo's 5MΩ Input Impedance provides the ideal load for the pickup, allowing it to operate optimally and restore a full, warm acoustic tone.
The internal Class A JFET circuit not only buffers the signal, but also provides subtle Gain, amplifying weak instrument signals to a healthy Line Level, while maintaining extremely low Self-noise.

Triton Audio BigAmp FAQ
A：The main difference is the input impedance. The Piezo version is 5MΩ, designed specifically for piezo pickups; the standard version is 1MΩ, more suitable for passive magnetic pickups like electric guitars.
A：Absolutely. Harshness often stems from impedance mismatch, and BigAmp Piezo's 5MΩ high impedance can solve this problem, restoring warmth and fullness to the tone.
A：No. It is powered directly via an XLR cable by the +48V Phantom Power supplied by your mixer or audio interface, which is very convenient.
A：It's very suitable. As long as your violin or cello is equipped with a piezo pickup, BigAmp Piezo can provide optimal impedance matching, delivering studio-grade DI sound quality.
