Connect a line level audio input cable from your source (microphone preamp, EQ, 
guitar or bass preamp / effects box, analog console or analog output from your 
DAW) to the 3 pin XLR / ¼” female connector. The input connector is Balanced 
Transformer Coupled, pin 2 hot.

Connect an audio output cable to the 3 pin XLR male connector and plug it into 
the input of your recording or mixing device. The output XLR is Balanced 
Transformer Coupled, pin 2 hot.

Connect the supplied IEC power cable to the IEC mains socket on the rear panel. 
USE ONLY A 3 PRONG GROUNDED POWER CABLE. For safety reasons do 
not lift the ground on the power plug by using a 3 to 2 ground lift adapter.
