Noisy main outputs from T4S when using TRS 1/4" to XLR male to FOH
Hi all. On the T4S whenever I use TRS 1/4" to XLR male cables from the main outputs of the T4S to a mixer/FOH via XLR I can hear background noise , which resembles rumble and hiss. Even when all channels are muted, master volume down and nothing plugged in the inputs, I can still hear the noise. The headphone output does not contain the noise. I've tried different cables (Mogami Gold and Van Damme), and even a noise/hum eliminator in between the T4S and the FOH mixer, but still noise . However, when I use 1/4" TS to 1/4" TS cables the noise doesn't exist. Has anyone else experienced similar issues when using 1/4" TRS to XLR cables? It's important I use XLR connections, because it's easier when I turn up to gigs and connect to the FOH via XLR on the stage. Thank you Note: the firmware is up to date.
