Mic output of my pmp3000 is weak,levels must all the way up to get any mic sound louder,Im using balanced xlr's for my mics, Is there any adjustable sensitivity adjustment inside the mixer? like the one in amplifiers.. ACSound

You can use the Line In jack, but you will probably need to use a mic preamp to raise the mic output sufficiently. You can try using an inexpensive mic from an amateur karaoke system or Guitar Hero etc. If that mic has no 1/8 inch mini phone plug, you can look for an adaptor, or have a tech type person set the mic cable up for you. If you want better quality, borrow or buy a professional vocal mic which uses an XLR cable and adapt the cable to plug into the 1/8 inch Line In jack on the keyboard. As I said, if the mic level is not loud enough, you can use a mic preamp, such as the ART Tube Mic Pre, which you can find used, or on a clear-out for maybe $25 to $35. Use a cable with a 1/4 inch connector on one end and a 1/8 inch connector on the other, to connect the mic pre output to the keyboard Line in. Plug the mic into the XLR input of the mic preamp. This will work 100%. Just adjust the mic preamp level controls carefully.

You have NOT told us what speakers you are using or anything to help us help you. That mixer will produce about 250 watts a side into 8 ohm speakers. That should fill a 30 by 50 foot area. You will need at least 15 inch speakers. Proper mixer setup is important. Look at videos on the subject on YouTube for instructions. Many people use too much high frequency EQ setting. Set the EQ flat to start. Use minimum of reverb to start. Use good quality mics with XLR to XLR cables... none of this Radio Shack or Karaoke quality. Minimum mic cost iis around $90 for decent ones... or about $70 when bought in lots of three or more. For your speakers make sure they are elevated on speaker stands. Use the PFL to solo each channel and set the TRIM level for each as the first step.

You should be using Dynamic mics such as a Shure SM58. They go into the first FOUR channels and if there is excessive gain and distortion, push in thee Pad button below the connector for those four channels. Inexpensive consumer microphones used with some Karaoke home systems are not suitable for this unit. You should be using XLR cables on the mics (balanced lines). The Pad buttons reduce the gain by a fixed amount of -20 Db for mics that have too much output to be controlled by the gain controls right above the connector. Ideally those should be no less than 12 o'cloock for good signala to noise ratio. Additional channels beyond the first four do not have as much gain and they do not have the -20 Db pad option.

Make sure you are using BALANCED line to this... XLR connections boyh ends. Make sure ALL interconnected devices are powered from the same receptacle or power conditioner. Test your cables... they do go bad. This unit REQUIRES line level input. Do NOT expect a mic to drive it directely. Make sure your mixer uses the XLR outputs and is powered from the same receptacle, even if you have to run an extension cord to it. This is a bi-amped speaker so there are independent amps for high and lows. With nothing out and known good in there is very little electronics before the signal is split to the separate amps. At line level, your volume control should probably be about 2 o'clock with the EQ's straight up flat.

The XLR are intended for mic and as such they have the gain needed to use mics.
The connectors on the back are LINE LEVEL connectors. To use a mic with these, you will need to have mic preamps to send adequate levels into the jacks on the back of the unit.

There are many models of the Eventide and how to hook them up will vary and depend if you have multiplle mics that are to be serviced. If you have multiple mics, I would be tempted to run the mics into some of the channels of the PMP but tur their faders to zero and send them to MONITOR 1. Come out of the MONITOR 1 jack to go into the Eventide and then run the Eventide into one of the line inout channels like 19/20. You would need to use balanced connections and some adapters from XLR to 1/4 inch to make the connections. There are MANY ways to configure this and depends what you are trying to do. If all audio is to go through the Eventide, then wire it as an "INSERT" for the power amp. This would require a special cables.

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.

Check if the PAN control for that channel is set at 12 o'clock position.

You can "pan" the mic to either L or R speaker or anything between.

On the Main/Mon setting, the level sent to the Mon side is controlled ONLY by the Mon level pot for that channel.

Some mics will require the trim gain to be full on. Check the mic gain by pressing the PFL for each channel and set trim to be below the clipping level with maximum vocal into the mic.

There are some low output mics that may be inadequte as far as output goes. Shure SM58 are industry standard mic... If you don't have one to try, borrow one to test with.

After that, the slider, EQ controls and the MAIN sloder has all the control.

Thiis amp has plenty of gain for mics. Make sure your mic has a good XLR to XLR cable (balanced) and connects to the XLR input connectors. If you have 1/4 inch jack cables that aren't TRS balanced on the mics, get rid of them and get XLR's.

Then push the PFL button down (LED will light red) for a single channel with a mic and adjust the trim (top knob for the channel) so that the level peaks without clipping on the main LED display when highest input to the mic is being generated. You should not get clipping then during operation.

After that you use the slider tio adjust the level for the mic. The MAIN slider should be at least up around -10 to zero during operation. If your main slider is way down, then you haven't balanced your channels properly. Do the same for each channel as the instructions for the mic above. If the gains of the other inputs are too high and the MAIN slider too low, this is what is causing your problem.

Typically the trims for mics like Shure 58 are about 3 o'clock.

High level guitars may have trims anywhere from 9 to 3 o'clock.

Ideally you will want your channel sliders to be between -10 and zero.
