Quad capture - no signal, condenser mic

Welcome tio the forum!

Do you have phantom power on???
(And I think the hi-z switch should be off when using a mic/phantom power, but I'm not sure if it matters).
 
Does the peak light on Quad blink with loud sounds?
How is the tracks in/out routing in SONAR?
 
Try to describe the details of how you have set things.

There should be no difference between your Shure and the condenser mic, the mic doesn't know what driver you're using, nor the drivers or the Quad know what mic you're using. If the Shure works ok, but the Se, using the same input, same cable, does not, it's hard to imagine other cause than something wrong with the Se or the phantom power feed of the Quad. Drivers do what they do no matter what type of mic you're using (USB-mics excluded).

Except for...One thing to try: A powered USB-hub. Maybe your USB-port doesn't give enough power for Quads needs when Phantom Power is used. The fact, that it worked for a while does not fit this scenario, though.

Have you tried pushing/twisting/shaking/toggling the plugs, the mic and the Phantom switch while trying o get the signal in.

Have you tried the same input as the Shure?  If Sonar records with the Shure then unplug it, plug in the se4400a, turn off the high z, turn on the +48 and see what happens.  If it doesn't record you have a problem with the mic or mic cable.  Note +48 must be on.
 
If it records you have a problem with routing it to Sonar.  For instance if you have the Shure plugged into input 1 but the se44004a is in input 2 then the se4400a's track input has to be set to right ....1-2.  Left is input 1 while right is input 2.  This holds true for all of my Octa-Capture inputs.
 
If this is redundant-sorry, but sometimes the problem can be very basic.
 
Good luck.
 
 

The computer, SONAR and Roland are three distinct entities.  SONAR needs to be right with the computer, which seems to work (you can get a signal out of SONAR, right?).  SONar connects to the Roland via drivers, which controls the ins/outs between SONAR and your hardware interface.  With ASIO drivers you get stereo paired connections - channel 1 right, 1 left, channel 3 right, etc.  If you are using ASIO (under Preferences), you have to unclick (highlight) any other drivers (WDM,  etc.) in order to use ASIO drivers or those other drivers will grab back control and your ASIO drivers won't make a sound.
 
If your ASIO stays clicked and at the top under Preferences, you should be good to go.  To record, you have to have the correct ASIO drivers connected to SONAR through its internal mixer.  You'll also have a soft mixer for the Roland hooked up right.  Finally, you have to have the correct hardware connection between the mic and Roland, phantom power turned on for the condenser mic and that hard input correctly assigned.  You might also find a hardware volume knob on the Roland  unit.  That, too, must be set correctly.  It can be confusing with so many spots to check the various connections that are pretty obvious on a  mixing console - tho if you take a look at a pic of an SSL console you probably won't understand it at a glance.  But all that mess of knobs and buttons is replicated by SONAR and your interface soft mixer - thus two places to make mistakes.
 
Hang in there - it is complex but solvable if the store can get the interface/mic to work.

To OP.
 
So is the mic not working outside of sonar. I'd try connecting to the second input (The Hi Z only works annoyingly for Input 1L, so try Input 2R just to pull that out of the equation. Then switch on Phantom power. The know next to the headphone jack, swing that around to right so it give you direct monitoring. May as well press the mono button too, to rule out it being a right channel issue. Tur upo the 2R gain control.
 
Also in the Quad Caputure Control panel, check that the Input 2 knob (not the Sens knob) is turned up. You could also check that turning the gain control (Sens 2R) on the Quad, and check that the software Quad Capture Control Panel's Sens knob is moving at the with it.
