The green light is NOT a tempo light and will not be in sync with applied audio. If you need a tempo indicator, turn on a click track in your computer or use a metronome.

Lexicon Alpha... | Answered on Feb 02, 2011

Hi. I think this is a simple fix.

I would uninstall your sound card software and reinstall it, as this sounds like thesoftware has a corruption issue. Reinstalling it should fix the problem.

Also, check your computer to make sure that there aren't any other interface software that is trying to use the same resources...i.e. irq, dma, or memory areas.

These can effect it as well. Also, you may have installed software that is calling on a specific region of memory, and that may be the same memory area as the Lex Lamba.

It may be that it an OS Xissue as well, so I would check to make sue that none of it's software is conflicting.

I know this may seem like a lot of different things, but you may find that after just doing the replacement of the software that the problem goes away.

If not, then at least now you know what areas could be causing it.

One other thing that you can try is to uninstall the sound card form the pc, and reinstall it in another location on the motherboard...i.e. move from one pci slot to another. It could be a slot problem.

Good luck, and I hope my info has been helpful to you.

Sorry, but the Alpha does NOT have Phantom power which IS required for a condenser mic.

You will either have to get a mic preamp that supplies phantom power or go to a dynamic type mic if you stay with the Lexicon Alppha.

First, I could NOT find an MXL99 microphone... IF you have an MXL990 microphone, you can STOP trying to have the Alpha read it because it won't !!! The MXL990 is a condenser mic and requires that Phantom power be supplied to it and the Alpha does NOT have Phantom power.
I have found a common problem on the audio interface inout is having to GO INTO the windows Sounds and Devices and verifying that under the VOICE tab, checking that the inout device is listed AND then checking the volume is turned up in that window... It seems like you have to verify everything and tweek a dozen places to get everything right to work. Having to look under the "VOICE" tab is not a good description of where the Alpha input control should be... so anyway, check that as well as it is not MUTED in that window. With Adobe Audition, make sure you set under the options, the "metering" to monitor the input recording level.

Lexicon Alpha... | Answered on Jan 15, 2011

I suspect the problem is with the software setup in your PC. Verify all the options and also verify that the AUDIO system is assigned as stereo and assigned to the Lexicon for both in and out... Also check any "PAN" control settings. There is a possibilty that the Alpha has a dead channel...

Try putting a stereo signal into the 1/4 inch jacks and see if both record... if NOT then take it for repair under warranty... I had a Lexicon Omega that had a problem myself... warranty repair...

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.

One can burn up equipment if you have powered parts of it from different sources...such as connecting things together that get their power from different receptacles. Ground bounce and fault currents of defective equipment can burn up things. You will probably have to send your unit back to the factory for repair.

Lexicon Omega... | Answered on Jan 08, 2011

Well, did you run the vocals through a mixer and send to BOTH channels of the Lexicon Alpha? If you connect the mic to only one channel you will only get one channel UNLESS you process the .wav file and PAN the vocal channel into both channels when outputing to your MP3.

Lexicon Alpha... | Answered on Jan 08, 2011

The probable cause is a ground loop. You haven't said what you are plugging in. These inputs are BALANCED lines and you MUST use TRS cables driven by TRS outputs of the thing you are driving it with. ALL interconnected equipment MUST be powered by the same receptacle or power source.
IF the thing you are driving it with does not have balanced outputs, then procure a DI (Direct Input) box and use an XLR cablle between the DI and the Alpha and set the DI on ground lift.

Lexicon Alpha... | Answered on Dec 28, 2010

You should be using XLR to XLR cable from the ART to the Alpha. You need to have recording software and the driver for the Alpha correctely loaded. Verify that in the PC when you go to the control panel in Windows and click on the "Sounds and Devices Icon that clicking on the VOICE tab that the Alpha is listed as the default audio for both in and out.

Lexicon Alpha... | Answered on Dec 28, 2010

I assume you're wrestling with the choice of using its onboard amp fed by the MV-5 or driving it from the CX-7's unused channel.

Of course either way will work. I'd go with the preamp-to-REL method as the REL engineers undoubtedly gave some thought to the amp design for the price paid.

Attach it to the Sub1 Preamp out


Lexicon CX-7... | Answered on Dec 26, 2010

Make sure that when opening the control panel and "Sounds and Devices in Windows that both the inpout and output show the Lexicon and NOT the normal audio of the computer. ALso make sure the volume slider in that section is shown as being full up.

Lexicon Alpha... | Answered on Dec 17, 2010

You should be at SP2, but that MAY NOT be the problem. One thing to check is if you are supposed to have the device connected when you install the software... in SOME cases doing it with or without connection will affect the outcome. Also make sure ALL virus/spyware/popup blockers are disabled during install.

Before using this device, make sure that going to the control panel and looking at the "Sounds and Devices" shows that the Lexicon is the inout and output device for all the tabs within that window.

An insidious problem is if the throughput of your computer is being used up by things like anti-virus, anti spyware. Turn OFF ALL of these throughput hogs when doing audio operations. Also turn off wireless communication and ANY other active USB throughput hogs.

These hogs will usually cause sharp noises thaat are essentially discontinuities of the audio waveform.

IF the noise you are getting is a "hiss" type noise, that is different. That is USUALLY caused by the user failing to set the gains and levels properly. Some electronic noise is from the statistical background noise likited by the laws of physics, It is important to record and set the level well above these noise floor points.

Balancing gain is important. Set the amplitude of the line out to be near line level and lower the gain of following amplifiers. This is just good practice.

Anyway, decide which of these two noise sources might be what you are seeing.

The third noise MIGHT be from ground loop noise... for that power ALL, and I do mean all interconnected equipment from teh same power receptacle/source AND used balanced lines such as XLR or TRS wherever possible.

That means that the card was installed on your computer. If so, then follow thw link below to uninstall and then reinstall the drivers.

You can reset your Omega by powering on the unit while holding down the Mic USB button and the Line 3 USB button.
