I have a new setup with a Heil PR40 mic, Mackie 1202-VLZ3 mixer and MULTICOM PRO-XL MDX4600.
If I don't use the send/receive on the mixer, everything sounds great. If I don't use the gate on the compressor/limiter, everything sounds great.
As soon as I get the gate going (which works great) - I get a hum which is picked up when I'm not talking.
Any thoughts? Is this normal? I'm new to this.
