SIUNIMAS RCA&AUX 1/8” Passive Stereo Inline Variable Audio Attenuator for Input&Output Adjustable Audio Attenuation Box for Home Theater and Official Performance Playing (SIM-AT-RCA/AUX)

Why it's a great deal

• 1. Passive design HIFI stereo audio attenuator, no external power required, plug-and-play design for home, office and car playing different using situations. Easy and convenient.

• 2. Independent Dual-Channel Control, two separate knobs for channels A and B allow asymmetric left/right multi-level adjustment, allowing fine-grained volume reduction control.

• 3. Compatible audio interface for 3.5mm AUX and RCA jacks, for easy connection to CD players, amplifiers, and other devices.

• 4. Broad attenuation steps, Channel A offers six steps from 0dB to -15dB; Channel B offers six steps from 0dB to -20dB. When both channels are used in series, a maximum attenuation of -35dB can be achieved. This stepped precision effectively bridges volume gaps between source devices and downstream equipment.

• 5. Wide application scenarios, Hi-Fi home theater systems(solving volume imbalance); Professional recording & live sound(Level Calibration); Car audio upgrades, resolves matching issues when factory head units output high-level signals that are too strong for aftermarket amplifiers; Audio testing & DIY projects, serves as a standard attenuation tool in audio signal chains for testing or pairing with other custom-built equipment.
