Description
Two Morley hum fixes and the cables to try them, packed together for chasing down buzz at a gig or in the studio.
Hum tends to come in one of two ways: through the mains earth, or through the audio cables between pieces of gear. This kit covers both. The Humno fits between a standard IEC power cable and your equipment's power inlet and filters the earth line without lifting the earth. An LED shows it is working, and Morley recommends no more than 8 A per Humno.
The MHE Hum Eliminator is a passive 2 channel box with custom 1:1 isolation transformers and XLR and 1/4 inch jacks, for breaking ground loops on line level connections. The kit adds an XLR cable, a 1/4 inch TS cable, a dual RCA cable, four RCA to 1/4 inch TS adaptors and two 3.5 mm TRS female to 1/4 inch TS adaptors. Morley puts it at 90% of the hum and buzz problems you are likely to run into.
Who it's for: Sound engineers, AV installers, band techs and studio owners who want a hum toolkit ready to go.
Who it isn't for: Noise generated inside a faulty piece of gear, mic or instrument level lines, or powered speaker lines. It is also no substitute for an electrician where building wiring is at fault.
