The Soft Limit LEDs indicate that the signal level is being soft limited. When 
enabled in the E-MU USB 2.0 Audio Control Panel, the analog soft limiters 
begin to gently turn down the gain whenever the signal level goes above -12 
dBFS. The soft limiters allow you to run a hotter signal without fear of 
clipping.

4. Main Outputs
The main outputs are normally connected to your monitoring system. The 
signal is duplicated on a stereo 1/8¨ jack for easy connection to desktop 
stereo speakers.
Use TS unbalanced cables for consumer-level line signals and TRS balanced 
cables for pro-level line signals. Balanced cables provide +6dB more output.

Synchronizing the 0404 with other Digital Devices
When interconnecting two digital audio devices using a digital interface such as 
S/PDIF, the two devices must be properly synchronized. Unsynchronized digital 
audio will result in random clicks, pops and dropouts, or even no audio at all. 
• The digital audio input is UNSYNCED if BOTH Sync Status LEDS are on.
• The internal and external sample rates are mismatched if the “Ext” LED is 
flashing.
