1. Giriş
The Double OS1 Resonance Pickup On-Board Preamp is an innovative guitar preamplifier system designed to enhance acoustic guitar sound. It features a unique Same Frequency Trans (SFT) transmission device that drives the guitar body to resonate, producing a more resonant, solid, and dynamic sound even without an external amplifier. This system integrates a dual-pickup setup, combining a piezo pickup and a microphone, to capture every detail of your playing. It also includes built-in reverb, chorus, and delay effects, along with Bluetooth connectivity for accompaniment.

3. Installation (Requires Opening Holes)
Bu, gemi içi bir ön hazırlıktır.amplifier system that requires permanent installation into your guitar. This process involves opening holes in the guitar body to accommodate the pickup unit and end-pin jack. Professional installation by a qualified luthier or guitar technician is highly recommended to prevent damage to your instrument.
The main unit is designed to be mounted on the side of the guitar, providing easy access to controls. The end-pin jack replaces the existing end-pin, serving as both a strap button and an output for connecting to an amplifier veya PA sistemi.

- Mikrofon: Adjusts the level or activates the internal microphone pickup.
4.3. SFT (Same Frequency Trans) Technology
The SFT system utilizes a transmission device to vibrate the guitar body, enhancing its natural resonance. This feature allows the guitar to produce a louder, more vibrant sound without requiring an external amplifier. The system picks up the guitar's sound and uses the transmission device to drive the guitar body, increasing its frequency response and making the sound more resonant, solid, and dynamic.
4.4. Dual-Pickup System
önamp incorporates a dual-pickup system consisting of a piezo pickup and a microphone. This combination ensures that every nuance of your playing is captured, adding richness and dynamics to the guitar's amplified sound. The microphone component requires connection to a speaker system to be effective.
4.5. Dijital Sinyal İşleme (DSP)
The system features advanced scientific circuit design with DSP (Digital Signal Processing) for enhanced acoustic dynamics and digital gain output. This ensures high-quality sound processing for the integrated effects and overall output.
