Soncoz SGL7 High End Pre Amplifier

Soncoz SGL7 Highlights & Core Features.

Chassis Structure & EMI Shielding

The unit adopts a CNC-machined multi- chassis structure to effectively isolate electromagnetic interference, delivering a clean hardware environment for
audio- signal transmission.

Dual- Isolated Linear Power Supply

Fully-isolated dual linear power supplies serve analog and digital circuits
separately, eliminating digital-noise crosstalk for a quiet, low-noise listening background.

Digital-Signal-Processing Core

Integrates ROHM flagship DAC chip BD34302EKV, Xmox and AK4118 digital-processing chips, paired with ultra-low-jitter oscillators, together with high-precision op-amp IV-conversion circuitry to form a high-performance digital-decoding path.

Complete Analog-Signal-Path Tuning

Multiple high-precision op-amps handle signal conditioning alongside
custom audio- coupling capacitors, consolidating overall performance and building a solid tonal foundation.

High-Precision Volume & Gain Adjustment

Equipped with JRC72323 analog-ladder volume control with 0.25 dBper step. Continuous 6 dB gain adjustment is available in pre-amplifier mode.

Comprehensive Professional I/O Configuration

Digital Input: USB, Optical, Coaxial, AES, Bluetooth,Digital Coaxial output
Analog Input: 2 × XLR balanced + 3 × RCA single-ended (5-channel total)- Analog Output: 2 × XLR balanced + 1 × RCA single-ended (sub-woofer
compatible), fully suitable for consumer-grade and professional-application scenarios.

MCU Global Soft-Control for Pop-Free Operation

MCU-based global software control eliminates almost all POP noise during power-on, power-off and input-source switching, protecting down stream power amplifiers and loudspeakers.

High-Definition Display & Parameter Memory

Features a high-definition display with independent parameter memory for
each channel. Multiple background- color options and 5-level brightness
adjustment adapt to various operating environments.

 Versatile Convenient Operation

Three control methods are supported: front-panel keys, rotary knob and infrared remote control for quick and intuitive adjustments.

 System Trigger & Auto-Standby

Supports Trigger-in linkage to synchronize with full-home audio-video
systems. Auto-standby function is included for system-integration
requirements and energy- saving purposes.
