High-quality Operational Amplifiers

Soncoz has designed the SGA1 amplification circuit with carefully selected operational amplifiers(OPAMPs). It is equipped with multiple units of OPA1611, OPA1641, OPA1622 OPAMPs. Four OPA1661 units are arranged in the RCA and XLR input buffer stage, the pre-output buffer uses four OPA1611 units, Headphone Amplifier buffer uses four OPA1622 units. There are two OPA1641 in the electronic output buffer. These high-quality OPAMPs ensure you get ultra-low noise and distortion in the output.

Precise Volume & Gain Adjustment With Memory Function

Your Soncoz SGA1 will precisely memorize your volume and gain settings on each combination of input and output. You don't have to adjust the volume or gain level every time you switch between the output options. The SGA1 is equipped with a MUSE72320 electronic volume adjustment resistance ladder circuit that allows for precise volume and gain adjustment without introducing noise or distortion in the output.

High-Quality Power Supply

Soncoz has designed a custom toroidal transformer with multiple layers of permalloy shielding for the power supply on the SGA1. It effectively provides clean power to each and every component on the audio circuit ensuring you a high-quality performance.

High-Quality Audio Circuitry

SGA1 is designed with high-quality components on the audio motherboard to ensure high-quality performance. The rectifier circuits of SGA1 use two large capacity(8200uF*2) ELNA audio capacitors to ensure the ultra-low ripple voltage of the main power supply. In the key audio signal path, SGA1 uses WIMA MKS2 series non-polar film coupling capacitors that greatly improve the quality of the audio signal.

Multi-Function Knob Button

Soncoz SGA1 Knob features a multi-function button that can be used to access different features on the device. If you want to mute the output and put the SGA1 into standby mode, simply press the knob button once. It will mute the SGA1 and the “V” or “G” will flash on the screen. After about 40 seconds the screen will gradually dim until it goes out and the device falls into standby mode.
