Engl Fireball 25 on Half power

Testing the Engl Fireball 25 KT77 on half power with master volume at half. Audio capture is an SM57 into an Alan & Heath digital mixer recorded onto an SD card. EQ in the SM 57 channel is flat apart from a high pass filter. Other Audio capture is a shotgun mic on the main video cam. Both blended together to give an accurate account of the sound in the room.
