Bring your analog sources together with precise volume control and flexible system matching. 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.
A 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.
Independent 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.
An MCU manages relay timing during startup, shutdown and input changes. Muting and sequencing are designed to reduce switching transients, helping provide smoother operation when changing sources.
Select 0 dB, +3 dB or +6 dB gain to match your source output level and downstream equipment. Set gain conservatively to avoid overloading the next component.
The voicing modes adjust analog-stage operating parameters rather than applying digital equalization. Perceived differences will depend on your source, amplifier, speakers and recordings.
Connect up to two balanced XLR sources and three RCA line-level sources. 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.
For 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. Digital sources need an analog output or a separate DAC.
The 3.7-inch IPS LCD has a 240 × 960 resolution, five brightness levels and four seasonal interface themes. 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.
The 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. Infrared remote operation is available with the remote-equipped variants.
A CNC-machined aluminum enclosure uses separate internal compartments for power, amplification and control circuitry. The 430 mm-wide chassis weighs 8 kg. Trigger input/output uses 3.5 mm mono connections with a specified 5–12 V DC range for compatible equipment.

Confirm the mains voltage selector matches your local supply before connecting power. The internal op-amps are socketed, but replacements must be electrically compatible with the specific socket and circuit. Disconnect power before servicing; op-amp replacement should be performed by a qualified technician if you are unfamiliar with the procedure.
A new tariff system will take effect across all 27 EU member states starting 1 July 2026. The EU is abolishing the duty exemption for low-value parcels — all goods entering the EU will now be subject to customs duties, including a fixed duty of €3 per HS tariff code category for IOSS-declared goods under €150.
A handling surcharge of USD $5 has been applied to all standard shipments to EU countries on orders under $100. Orders over 100 qualify for free expedited shipping.
