<br>
Have you experienced such breakage with dbx gear, or are you talking in general?<br>
<br>
The dbx output board has a bunch of passives on both input (probably<br>
for providing phantom) and output (and I wonder if this is for<br>
protection against phantom).<br>
<br>
Can someone make out what's happening on the board?<br>
<br>
The connectors are:<br>
<br>
J1 - XLR input<br>
J2 - TRS balanced input<br>
J3 - TRS insert send/return<br>
J4 - TRS balanced output<br>
<br>
