The Ultimate Ground-Loop Cure for Complex Guitar Rigs

The Guitar Sanctuary is pleased to present the Mesa Boogie Clearlink Receive Converter—the professional touring standard for eliminating ground-loop hum, signal degradation, and phase issues in multi-amplifier setups. Handcrafted in Petaluma, California, this studio-grade utility device is engineered to receive a balanced, low-impedance signal from a line driver (such as the Mesa Stowaway or Clearlink Send) and convert it back to an unbalanced, high-impedance signal safely optimized for your amplifier's input.

Studio-Grade Isolation Without Tone Degradation

When routing long cable runs across large stages or splitting your signal to run a dual-amplifier stereo rig, completing an electrical loop between two separate power sources almost always introduces a loud, distracting AC ground hum. The Clearlink Receive solves this issue completely by using a premium, custom-wound isolation transformer. It physically separates the electrical grounds between your signal sources while preserving the full dynamic range, punchy low-end response, and sparkling high frequencies of your guitar tone.

Professional Stage Controls: Phase and Ground Defense

Built into a rugged, road-ready aluminum chassis, the Clearlink Receive provides crucial problem-solving features for real-world stages:

• Ground Lift Switch: Safely breaks the ground connection between your pedalboard or line driver and the receiving amplifier, instantly killing stubborn ground-loop buzz.
• Phase Flip Switch: Inverts the audio signal's polarity by 180 degrees. This ensures that when you are running two different amplifiers simultaneously, their speakers push air in perfect synchronization, preventing the thin, hollow sound caused by out-of-phase signals.

Premium Technical Specifications

• Handcrafted in the USA: Built with premium components in Petaluma, California.
• Circuit Type: Passive design utilizing a premium custom-shielded isolation transformer (Requires no external power).
• Inputs: Balanced XLR and 1/4" TRS line-level inputs.
• Outputs: 1/4" Unbalanced high-impedance TS output optimized for instrument preamps.
• Controls: Dedicated Ground Lift switch and 180° Phase Reversal switch.

Product Intelligence & Intent Mapping

• Best For: Multi-Amp Rigs, Stereo Pedalboard Layouts, Long Stage Cable Runs, and Eliminating Ground Hum.
• Tone Profile: 100% Transparent, Phase-Correct, Full Frequency Retention, Noise-Free.
• Compared To: Radial Twin-Iso, Lehle P-Iso, JHS Output Buffer, Ebtech Hum Eliminator.
• Sanctuary Expert Note: "The Clearlink Receive is the secret weapon for anyone building a dual-amp rig. If you connect two amps together and hear a loud hum, don't change your pedals or cables—you have a ground loop. This passive box completely isolates the connection and preserves your tone, while the phase switch keeps your speakers moving together for a massive, focused sound stage."[cite: 5]
