The SONCOZ SGL7 combines a fully balanced analog signal path, relay-controlled R-2R attenuation and separately powered analog and digital control sections. Whether you are settling in for a late-night vocal album or switching to a large-scale orchestral recording, its gain settings and three analog voicing modes let you tailor your setup without DSP.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e12-bit R-2R relay attenuation with 0.25 dB volume steps.\u003c\/li\u003e\n\u003cli\u003eFive analog inputs: two balanced XLR and three unbalanced RCA.\u003c\/li\u003e\n\u003cli\u003eThree analog outputs: two balanced XLR and one unbalanced RCA.\u003c\/li\u003e\n\u003cli\u003eSelectable 0 dB, +3 dB and +6 dB gain.\u003c\/li\u003e\n\u003cli\u003eNeutral Balanced, Warm Vocal and Dynamic Resolution voicing modes.\u003c\/li\u003e\n\u003cli\u003eIndependent linear power-supply paths for analog and digital circuits.\u003c\/li\u003e\n\u003cli\u003eCNC-machined aluminum chassis and a 3.7-inch IPS display.\u003c\/li\u003e\n\u003cli\u003ePer-input parameter memory and trigger input\/output for compatible systems.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003ePrecision Relay-Controlled Volume\u003c\/h3\u003e\n\u003cp\u003eA 12-bit R-2R resistor network uses sealed relays rather than a sliding potentiometer for attenuation. The specified adjustment range is -54 dB to 0 dB in 0.25 dB steps, with channel tracking error below 0.05 dB. Fine adjustment helps you set a comfortable listening level while maintaining left\/right balance.\u003c\/p\u003e\n\u003ch3\u003eSeparate Analog and Digital Power Paths\u003c\/h3\u003e\n\u003cp\u003eIndependent transformer windings, rectification and regulation serve the audio stages and digital control circuitry. This separation is designed to reduce control-circuit noise entering the analog signal path. The supplied specification lists a 3 µV noise floor.\u003c\/p\u003e\n\u003ch3\u003eControlled Switching for Reduced Transients\u003c\/h3\u003e\n\u003cp\u003eAn MCU manages relay timing during startup, shutdown and input changes.

Two XLR outputs and one RCA output provide options for compatible power amplifiers, active speakers or a powered subwoofer. The RCA output is not specified as a dedicated filtered subwoofer output.\u003c\/p\u003e\n\u003cp\u003eFor vinyl playback, connect the output of a suitable external phono preamplifier. Do not connect a turntable cartridge directly to a line-level input unless the turntable has a built-in phono stage.

Front-panel buttons and a multifunction rotary encoder provide direct operation. Each of the five inputs stores its own volume, gain and voicing settings, retained after power-off.\u003c\/p\u003e\n\u003cp\u003eThe supplied documentation describes standby after a 90-second muted or idle period followed by a 10-second countdown. Front-panel or remote commands wake the unit.
