Trying to record a mix through a peavey board. I do not get a high pitch hum until I click rec on my Mac. I am connected via usb to the mixer board. Any suggestions on what I might could try to stop this...


First, check your levels on the console. Is anything turned up high, channels, gain settings on channels? Check and see if the noise exists whith the main outputs muted or turned down. If it goes away it is a fader or gain setting on a channel. If it persists, then you have a co nection issue with the USB . Try a different cable. Make sure the Mac is on the same electrical circuit as the mixer, or if it is on battery, try adding it on the electrical circuit with the mixer. See if location of the mixer to the computer makes a difference as well. They may be too close to each other. Hopefully one of these things will fixya.

I need to know how to raise and lower the pitch


In principle, the primary oscillator needs to be adjusted- some keyboards have a pitch or bend control that if not set correctly, it will affect the tone of the entire piano.

6505 +112 has a bad hiss with nothing plugd in


Some hiss at high gain settings is normal. If you get objectionable hiss at 1 o'clock settings of gain, that is too high. Electronics has noise that is "statistical" in nature due to physics that we can't get around in design. Most hiss is created in the preamp area and swapping tubes in the first stage might help. By varying the volume controls and observing the level of the hiss, we may be able to analyze the offending staage of amplification. ALso turning up the treble controls will increase the hiss, as it is mostly in the higher pitches.

I have a Peavey 8600 amplifier. It sounds great but when only operating vocals, in order to get the highs of your voice just right, the speakers put off a large amount of white noise. While singing, you...


There is not enough info here to provide a complete answer, but let me give you some background:

There will always be some hiss. This is due to general amplification where a small amount of noise is amplified along with the general signal. In most cases, the signal is strong enough to overpower any noise that is present (vocals in your example). This noise should not be that noticable in normal cases. If there is an automatic gain control in the line, this could account for it as with "silent" times, the gain will automatically be increased potentially to the degree where the noise is noticable.

Barring that scenerio, if the input signal is too low, the overall gain necessary to produce reasonable volume at the speakers will also be such that the noise is noticable. In order to track this down, please provide details about the current setup including:

1) Microphone make and model being used
2) Input being used on the mixer
3) Gain level being used for the mic channel
4) Gain level being used at the master level.

I plug it in and all it does is make a high


Make sure you either use a fresh, name brand battery or correct AC adapter.

Turn all controls down at first as it is possible this pedal may feedback internally if controls are all up.

High pitched noise from amp


Theonly user serviceable thing for you to check is the batteries OR power supply. If that were low, that could cause the problem.

Lexicon alpha interface is recording a faint high pitched sound


Check for ground loops.

You MIGHT be able to cut the noise by setting the EQ's to clip the highs.
