1. Киришүү
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)
This is an on-board preamplifier 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 ampкөтөргүч же PA системасы.

The main control dial and surrounding buttons allow for easy adjustment of various parameters:

Figure 4.2: ашыкview чейинкиamp башкаруу элементтери.
- Контроллер: Main rotary dial for adjusting volume and navigating settings.
- Dial LED Lamp / Indicator: Provides visual feedback on settings and battery status.
- Type-C интерфейси: Used for charging the internal battery.
- BT (Bluetooth): Activates Bluetooth 5.0 connectivity for pairing with external devices (e.g., smartphone) to play background music or accompaniment.
- AUX: Likely an auxiliary input or function related to external audio.
- Реверб: Controls the reverb effect, adding spatial depth to the guitar sound.
- Хор: Controls the chorus effect, creating a thicker, modulated sound.
- Кечигүү: Controls the delay effect, producing echoes of the guitar sound.
- Микрофон: 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
чейинкиamp 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. Digital Signal Processing (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.
