SONCOZ SGA1 is a High-Fidelity fully balanced headphone amplifier and design for the High end series,pre-amplifier that is designed with high-quality components to ensure high-quality performance. It features a fully balanced architecture with XLR input/pre-out and 4-pin XLR+4.4mm headphone output ports. Soncoz has planned the SGA1 matching the shape, and style of their leader DAC SGD1.

Carefully Selected 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 For Clean Power Delivery:

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.

Available in Two Different Color Options:

SONCOZ SGA1 is released in two different color options, Deep Black and Deep Silver. The Deep Silver matches the design and aesthetics of the flagship SGD1 Balanced DAC by Soncoz. The SGA1 is designed to be a companion to the SGD1, completing a fully balanced headphone and pre-amp stack.


 

What's in the Box?

Q1: Are the PRE and HPA outputs at the same time?
A1: No. PRE and HPA have separate signal paths.
Q2: Are the HPA 4-Pin and 4.4mm balanced output at the same time?
A2: Yes. But they can not be used at the same time.
Q3: Does SGA1 has a memory function?
A3:Yes. The state of each input and output as well as the corresponding volume and gain values can be memorized.
Q4: How to adjust the volume quickly?
A4: When the SGA1 detection knob is turned rapidly, it will automatically enter the mode of rapid volume adjustment, and when it is detected that the knob is turned slowly, it will enter the mode of fine adjustment.
Q5: Is the gain continuously adjustable?
A5: Yes. Gain is adjusted by 0.5dB/step.
