EDIROL UA-25 purchase and initial failer

EDIROL UA-25
EDIROL UA-25 was purchased as a one for sound recording of narration.

Whether the sound recording playback with 24bit/192KHz which does not change price that much it makes FA-66 which corresponds to multi input being to be troubled rather, it does, but DAW (Desktop Audio Workstation) it is not the case that it has been advocated, if just I use, as AD converter whose supply of Phantom power source is possible being something that due to sufficiently judgement with this it does.

In order that the audio booth and the like you desire, under the environment which is not, clearing narration is drawn up, the quiet sound conversion of PC becomes first problem.

Presently, most quiet sound PC File is Server/FTP Server, but also, considerably the deviation stripe sushi, the necessary time, are one of the reasons which with USB Cable 1 choose UA-25 even from the connected possible point which install Audio Card of treble quality from original purpose.

I use, as DAW a little there is a difficulty, e.g., you cannot use 24bit/192KHz, but in case of me, if you can use with 24bit/48KHz monaural, there is no problem you think that and, from the fact that also Peak Limiter is operational effectively, it is Tool which it is easy to use extremely.

Furthermore, you can use as for MIC where you have used, it is Rode BroadCaster but, without especially problem.

However, perhaps, individual difference, but when with Sound Forge 8.0 Recording circumstance is verified, as in the left figure considerable noise is riding in the right channel even in a state where it is finished to squeeze MIC Gain. (High impedance switch OFF)

When the high impedance switch is turned to ON, furthermore becoming bad, it becomes -67.0dB.

When MIC Gain is done maximum (high impedance switch OFF), when the left channel becomes -50.4dB, and the right channel becomes -28.4 dB, tries looking at the ripple mark really and it understands clearly that suitable noise is riding.

As expected this just a little.... 。(UA-25 Noise.mp3 as for PC which is connected this)

With being the case that it is said, I would like to try inquiring in COMPMOTO ahead purchasing.

When there is the below-mentioned reply from COMPMOTO ahead purchasing, it exchanges concerning the initial failer, is. Until I use in earnest, already time may be required a little, is.

To inquire it is the case which it receives but at our company making the manufacturer verify, when it receives, being the initial failer way, when sending we would like you to be able to point to the exchange commodity, I know.

If at cash on arrival you can send the commodity which to labor assistant is to our company.

Sending being able to point from this day our company Tokyo warehouse concerning the exchange commodity, being to receive, if now you can wait for a while to arrival.

This time we multiplying the number of hands, there is no excuse truly.
No soldier/finishing we ask may.

The exchange commodity reached with air mail. You were surprised to the speed of exchange correspondence of COMPMOTO. Well, it is state of the exchange item, but when it is finished to squeeze MIC Gain also both channels -80dB are below, there is no problem are. (High impedance switch OFF)

When MIC Gain is done maximum (high impedance switch OFF), this time, noise rides in the left channel, but it is the level which completely does not have problem. (UA-25 Noise2.mp3 )

To the last, it is private opinion, but as for the one where it think of DAW with UA-25, that I think whether from the one which the superior type is selected, is not there is no being regretful. (Most is constructed as for the one which I think real DAW with UA-25 that excessively you are not, but...)

Being to be thought, that it solved, it does, noise problem, but the exchange item noise influencing reversing sound recording midway, it understood that it returns to the state before the exchanging. As for the noise grade of UA-25 the never good way you think. Furthermore,the circumstances where noise influences reverses with UA-25 Noise2.mp3 understand.

Because also the affinity of PC which you connect it is thought,you connected to another PC and Note PC, but the result was the same. It seems like the problem of UA-25 itself.

Price.com with the thread of UA-25, being to exchange this noise problem, it does, but among those cause was ascertained.

Condenser MIC for business is used, +48V Phantom power source is necessary, but when SW of Phantom power source of UA-25 is turned to OFF, present trouble like lie it is gone.

+5V the occasion where it boosts in +48, it seems that the noise remains from USB. Among the person who uses UA-25 class the people where +48V needs Phantom power source are few, excessively are thought as the thing which has not become problem.

It probably means that the one whose +48V Phantom power source is necessary from has no other choice but to select the superior type.

There was reply from Rolland.

To inform on the basis of the circumstance which it receives, at the product charge post investigation when it does, when when the condenser microphone of Phantom power source correspondence is not connected the Phantom power source of UA-25 is turned to ON, because it becomes state of no load, when it becomes easy to pick up noise, it was thing.

Fear it needs, but turning Phantom power source to a OFF without being able to use with a state where the microphone is not connected, it does?
This is similar even with FA-66 not only UA-25.

UA -25 and FA -66 the fact that Phantom power source noise rides seems like specification. It seems that for the time being Rode Broad Caster => Mackie 1402VLZ Pro => DBX266XL => UA-25.

Size becomes large, but BEHRINGER B-CONTROL AUDIO BCA2000 of the same price range, a little price becomes high, but after looking at the appraisal around TASCAM FW-1082, it is the intention of purchasing anew.

BEHRINGER B-CONTROL AUDIO BCA2000 although being the same price range as UA-25, correspondence of the correspondence of 24bit/96KHz is possible, there is a good bargain impression.
