Only on one side

There has to be some sort of conflict between the two units and you may have to use a different mike and/or setup.

on the left side of the unit there is a small switch , , set this switch to MIc , or if using a condenser mic set to phantom-mic this gives the mic power , but I will caution you to watch you units power ind as with that setting you battery will drain down quicker than usuall , you will get best results with balanced mic's as the other types will introduce noise (thumping sound) into the recording also try to keep cord lengths down to less than 15 feet as this will introduce noise into recording as well

From the Micropower PS400 product description it states:

"routes the microphone signal to a mixer or a microphone preamplifier."

• these is just a phantom power supply.


One reason your former setup is OK , is that

tascam m-50 is a mixer preamplifier.

• phantom power supply is just a part of the mic preamp of the mixer

to power up your mxl 990 condenser mic


• What you may need is something like these:

X2u XLR to USB Signal Adapter

Sorry, but the Lexicon Alpha does NOT have Phantom power and you can't use a condenser mic with it without a Phantom power injector or preamp.
If you mean you have a Phantom power injector then it should be working. Do you have seperate mics for the two channels of the stereo? If you have only one mic, then only one side will record unless you set for mono recording and then dump the recording into stereo voa Cubase. I would recommend you get a small mixer... even a 4 channel one to use ahead of the Lexicon so you can mix and PAN your mics the way you want them. The recording and trying to control the panning in Cubase can be frustrating... The Lexicon really doesn't have anything built in to PAN the mic to the center when stereo recording. Small mixers are inexpensive and often you can find them used or in pawn shops for cheap.

Tascam-us100 interface doesn't have phantom power; condensor mics need phantom power to operate

A little testing is required to nail this down.

1) Will a standard mic work in either channel?
2) Will a line level source work in either channel?

It is likely that either the power supply for the phantom power or the supply for the mic pre-amp IC has failed or the IC itself has failed. If a standard mic works, then it is the phantom power supply that is faulty.

I am not aware of any service manual available other than from Yamaha directly (for a price of course...)

If you can update this with the test results, perhaps we can walk through this repair.

Unless you have the FX model, there is no Phantom built in. You will need to get an external Phantom Power Supply, such as this one by Audio Technica http://www.zzounds.com/item--DAVAT8801

Phantom power should only be used with a condenser/ribbon mic. If you're using a dynamic mic (like the one in the photo) you don't need phantom power. Also I run my mics and instruments through a mixer, then into the unit. Also if you're mixing your masters at a low volume, the CD will play at a lower volume. Try mastering at as high a volume as possible, avoid clipping of course. But get it as loud as possible while mastering. Then the master copy should be louder. I have a DP02 and found out it needs decent monitors to mix and master. That's all I've got.

Hi,

You'd plug the XLR connection into any of the first four inputs on the 2488 (labelled a to d). This is a dynamic mic so you don't need phantom power and should make sure your phantom power switch is off (out) on the 2488. You'd then assign the input you've chosen to a track, arm the track for recording, turn up the input level for that input to test the signal level, and record away by pressing record and play together.

Hope this helps.

This set-up is very compatible and you should have no trouble at all.
