X-CONNECT Adjustable Attenuator

The Harrison Laboratories X-Connect™ Adjustable Attenuator is a rugged, palm-sized solution for audiophiles and installers who need precise control over high-output signals without sacrificing sonic transparency . Engineered as a passive device, it manages audio levels while remaining "invisible" to the signal path, ensuring that your system’s tone remains untainted by electronic noise .

Physical Profile & Build

• Chassis: The unit is housed in a high-impact polycarbonate case designed for durability in demanding environments .
• Dimensions: It features a compact, nearly square footprint of approximately 2” x 2” x 1”, making it easy to tuck away behind head units or within tight amplifier racks .
• Terminals: It is equipped with standard RCA female input and output jacks, ensuring universal compatibility with both consumer and professional audio cables .

Performance Highlights

• Variable Control: Unlike fixed pads, this model allows you to adjust attenuation from 0 dB (no reduction) to infinity (full mute) . This makes it an ideal tool when you are unsure of the exact attenuation needed to stop input stage clipping .
• Dual-Channel Design: It operates as a two-channel device with separate, independent adjustments for each channel, allowing you to fine-tune the balance of your stereo image .
• Integrated Ground Loop Eliminator: Modern versions include a built-in isolator to strip away alternator whine or ground-induced hum that often plagues car audio and vintage tube amp setups .
• Sonic Transparency: Because it is passive, there are no active circuits to add distortion; its noise floor is effectively "too low to measure"

This attenuator is particularly effective for systems where the source unit has a high voltage output (like 8V line drivers) that would otherwise force an amplifier's gain control to stay at its lowest, noisier setting.
