Description
Overview
The Morley Hum Eliminator 2 is a professional-grade, 2-channel isolation box designed to instantly remove ground loop hum and cable-related noise from your signal chain. By utilizing high-quality 1:1 isolation transformers, the HE-2 breaks the loop antenna and balances audio lines, ensuring a clean, noise-free signal between offending pieces of equipment.
Built for reliability and versatility, this passive device requires no external power and is housed in a rugged, cold-rolled steel chassis, making it an essential utility for any studio or live stage setup where electrical interference is a concern.
Key Details
- Ground Loop Elimination: Effectively removes hum and buzz by isolating the ground connection between devices.
- 1:1 Isolation Transformers: Uses precision transformers to break loop antennas and balance audio lines without altering the signal level.
- Signal Conversion: Capable of converting balanced signals to unbalanced and vice versa.
- Smart Jack Technology: Equipped with 1/4″ Smart Jacks that automatically accept any combination of mono (TS) or stereo (TRS) plugs.
- Passive Design: No batteries or power adapters are required for operation, ensuring instant deployment.
- Industrial Build: Encased in a durable cold-rolled steel housing for maximum longevity in demanding environments.
Use Cases
- Live Performance: Place the HE-2 between a guitar amplifier and a powered speaker or mixer to eliminate 60-cycle hum caused by different power circuits.
- Studio Integration: Use the unit to isolate outboard gear or synthesizers from an audio interface to prevent ground loops.
- Signal Balancing: Convert unbalanced instrument signals to balanced lines for longer cable runs without signal degradation.
- Multi-Channel Isolation: Utilize the 2-channel configuration to treat stereo pairs or two independent mono sources simultaneously.
Installation
Installation is straightforward and requires no configuration. Simply plug the Hum Eliminator 2 in-line between the two pieces of equipment experiencing the hum. Connect the output of the first device into the input of the HE-2, and the output of the HE-2 into the input of the second device. Because the unit uses Smart Jacks, you can use standard TS instrument cables or TRS balanced cables without needing to switch settings.
Compatibility
- Connector Type: 1/4″ TS (Tip-Sleeve) and TRS (Tip-Ring-Sleeve) plugs.
- Signal Types: Compatible with both balanced and unbalanced audio signals.
