Question

i'm using a rode nt-1a through a firebox, and logic isn't responding. the preference for both system and for logic show the firebox as the audio input source. any ideas?

+*Lets start with your hardware first. Lets assume all your connections are correct and cables are in good working order:*+
Is there anyway to verify that signal is getting to the Firebox from your mica such as an LED VU/db meter and is the preamp level set appropriately on the firebox? No signal here means no signal into Logic.
Can you hear any playback from Logic and the Firebox? Are there any other working inputs on the firebox such as SPDIF or Line Level 1/4 input? If so, it may be a bad input channel
+*Possible Software Issues:*+
If the Firebox is setup as the default audio device for your MAC, deselect in the OSX System Preferences. The system may be taking priority of this device even though Logic recognizes it. This is usually not a problem on most systems however because most of professional audio devices are full duplex and can be accessed by multiple program at once.
When you create a track to record this microphone signal, are you not seeing or hearing anything with the input monitoring button engaged? Sometime you have to engage the record button first, to engage the the track. It's a strange bug that occurs on my system.
