P 150 system fails when 2 or more inputs are used at once
If two guitars and a mic are plugged in and one line 's volume has a spike in natural volume ie., the singer sings louder or the guitarist hits harder, t.he sound shuts of for a moment coming back on in a second or two

Re: P 150 system fails when 2 or more inputs are used at...
If you have an owners manual make note that channel one has a VIP feature with a control. This feature makes channel one override the other channels and is used for voice over announcements. The manual explains how to use the threshold control to set this. It can be downloaded at Fender.com/support.

If you are using the fx/send port to the mic-in port (I have no idea why you would want to do that) but nevertheless, check the red fx dial and make sure it is at 12 oclock and turn the pan dial to 12 oclock also. remember if you are using mic input 1 or 2 with a mic that requires Phantom power the button needs to be locked in the down position. OK im assuming you have checked and set your gain and volume levels on the 802 prior to plugging in your mic. If not do so now.(unplug all outputs and with mic plugged in speak into the mic while turning up gain until you get distortion which is indicated by a rewd light next to the "pan" button...once you see that light turn the gain dial back slightly and you should be set) have volume at 12 oclock on both l"evel1" and "main mix: dials. Now goto your windows desktop and right click on your volume control "speaker" icon. Click on "Playback device" you should see your mic in the list on enabled devices.If you dont see your mic in list right click the screen and click show disabled devices. Enable your device. If it is already enabled right click it and make sure it is not muted. finally go back to list of playback devices and right click your mic and click "configure speakers" run through the tests. close everything.mic should be working now. If it is not I suggest you plug your mic into either the line in from the fx/send or keep it in the mic-in port and plug the other end into the head phones port.Or better yet, get an rca to mini stereo jack and use the cd/tape out jacks to send your signal to the mic port of your computer......keep playing with it...you'll figure it out.There are so many different ways to hook up your perephrials its mind numbing sometimes.
Talk to your sound man... It is possible he has a compressor on the line. A compressor adjusts the volume dynamically and delays tweeking and releasing as a setting. Your guitar should NOT run through a compressor.
Turn down the VIP knob and try it. This is on channel 1 for announcement voice overs overriding everything. It has a threshhold setting for adjusting that. Here is the manual for it. http://support.fender.com/manuals/pro_audio/Passport_P150_manual.pdf
You need to check the actual signal levels to make sure they are within the specs for the unit. The mic input is low impedance. Your mic should be like a Shure SM58 or equivalent. The output is fairly high... up to +14DB which will require you to turn down the trims on a mixer this runs into or set a -20Db pad at the input. I suspect your distortion is from the device output to the mixer input. It is VERY important that the mic does NOT "hear" the speakers as the feedback loop resulting will be mass distortion. The guitar should also not "hear" the mains.
You will use microphone with balanced XLR connector into the XLR mic input. Note, the ALpha does NOT have phantom power so you cannot use condenser mics.
A guitar can be plugged into the hi-z instrument 1/4 inch jack on the left front of the unit.
To use the line 1/4 inch inputs you will use BALANCED TRS 1/4 inch cables from your source.for these channels. The level on these needs to be line level.
The line outs are for sending audio out to an amp. There appears to be RCA outputs you can use as well.
I am not sure what you mean by making your "amp record"... An amp PLAYS the audio, usually into a speaker.
If you are trying to play a guitar through your amp AND record, then you will connect your guitar to the Alpha, the amp input will have a cable from say Line 1 OUTPUT and when recording wou will have the echo feature on so your guitar is passed through to the amp.
The piezo pickups for violins REQUIRE a high impedance input preamp.
The measured impedance of My wife's violin is on the order of 2 megohms.
It sounds like you are having cable connection problems. If you don't have a preamp right at the vilin, then use a VERY short high impedance instrument cable.
Most of the Focusrite mic preamps I looked at had input impedance around 5K ohms which is unsuitable for the piezo pickups.
Here we use an Autolycus pickup on an acoustical vilin and an X2 wireless system. The transmiter has a very high input impedance and the resulting system sounds like a violin.
Some amps themselves DO have a high input impedance, but many designed for guitars do not. Long cables, especially low impedance ones, load the piezo pickup with capacitance which clobbers the high frequency response.
With everything switched off. I will surmise that you are using the onboard battery with the foot pedal and not a power supply.
1. Plug lead from guitar/instrument into INPUT side of pedal
2. Plug lead from OUTPUT side of pedal into amplifier INPUT.
3. Turn amplifier volume to about 10 o'clock - to stop blowing your ears out.
4. Turn volume up on guitar to acceptable level.
5. press foot switch on pedal and adjust pedal controls to suit your type of distortion.
6. Play like Hendrix.
ps Just as an after thought rechargeable 9volt batteries are the way to go. I've been using them for years as I always get caught up in the power cable.
If you're going to add another pedal like a Phaser, Compressor, Flanger or what just use small connect leads between each pedal but always, always put the compressor pedal last in the line.
guitar amps are all set to a low Z resistance configuration. wich are made for guitar only. make sure you are using the right cables.
you need sheilded guitar cable not unshielded speaker cable in many cases these cables look exactly the same. look at your cable look for the words speaker or instrument. you need the instrument cable. if you still have that problem. then you may just not be satisfied with the quality of the amp it self.
