aschmidt21 posted a topic in Spider IV / Spider OnlineI have the Spider IV 30 -- the old model, with just four presets. When I change from one preset channel to another, on some channels I get hum/buzz/static, which disappears when I fiddle with the channel volume/drive knobs. Is this just one of those things that everyone experiences or can I adjust something to eliminate/minimize that? I also noticed that the volume differs from preset channel to channel -- goes way up or down as I switch. Any way to standardize the volume so that it remains the same as I change channels?
I helped a school to purchase 6 XD-V55L units. Five of them check out great, with good, clear sound. The 6th unit sends a hum, along with the signal from the mic. I tried it with different mics and different receivers. Any ideas? Thanks, Roy
I had an odd issue last weekend with one of my V70 belt-pack systems. I was running three of them plus my new V75 hand-held which I'd just used to update the firmware in all the V70 systems. All in RF1 mode. This particular system had the L6 lav mic attached (I normally use headsets but this particular performer insisted on a tieclip). The system was used on someone else earlier in the show and performed perfectly, but once fitted to this performer, the problem hit. I PFL'ed him just before he went out on stage and all I heard was a loud mains-type hum with some harmonics and a slightly digital quality to it. No wanted audio at all; just this unvarying buzzing. I think the level was lighting up just the bottom segment of the receiver meter. It was far too late at this point to swap anything out but as he projected well, he made it through his act without the mic. As it was a somewhat hectic show followed by a rapid get-out, I didn't have the time to go through any useful troubleshooting to narrow down what the problem might have been; unhelpful I know. I set up the equipment again back at base and couldn't make it misbehave in any way no matter what I did. My best guess was a dodgy connection between mic & belt-pack but no amount of cable flexing and connector wiggling and loosening would produce any issues. The venue was at the bottom of a cliff on the seafront where even mobile phone signals barely made an appearance; with no venue WiFi either, it was the quietest RF environment I've ever worked in. The other systems all worked perfectly throughout; this one was also fine up until that one act. My question therefore (and I know it's a bit of a stab in the dark) has anyone experienced anything like this or can anyone suggest a possible cause?
Q: How can I reduce hum/noise/feedback when playing? -Single coils pickups used with higher gain settings will often cause noise. Try combining two pickups via the pick-up selector or trying a different guitar to see if the situation is the same. Make sure all the input and output jacks are tight. Check the instrument with different pickup settings to make sure it is not a bad pickup connection. -Higher gain settings tend to be the cause of many noise and feedback issues, try to dial the gain back on your amp a bit. Remember that heavy-rock bands often triple track (or more) when recording to create a thicker sound. -Turn your volume knob off when you are not playing (even during stops in a song when possible). -Turn off other volume controls not being used (i.e. volume trim pots) -Use the highest quality cables you can afford, and the shortest distance you can live with. RF can create many noises that can be eliminated with well shielded cables. -Experiment with distance and position between your guitar and amplifier/recording rig. - Avoid florescent lighting when possible. - Make sure that your instrument/rig is plugged into the same power source as the rest of your gear/band/PA system (to avoid ground loops). - User a power conditioner/regulator to filter RF and keep the voltage constant. - Experiment with the noise gate feature on your Line 6 unit or use an external noise gate. Q: I hear a "popping" sound when I turn my amp on, is this normal? How do I reduce the popping sound I hear when I turn my amp on? A: The popping sound is normal as it is a ramp of up the switch mode power supply. You can lessen the effect by: i) not having the input plugged in (disengaging the preamp section). ii) having the master volume turned all the way down (lowering the power amp output).
