This is gain staging in reverse. I have an MBox2Pro which has a front panel volume control for the monitor output. I use unpowered speakers, so I have a monitor power amplifier with separate volume controls for each channel. The controls on the amp are really input attenuators. The amp is 100 watts a channel running into NS-10M speakers, which are rated at 60 watts, 120 peak. Should I run the amp full tilt at zero attenuation and control volume from the MBox? Or should I run the MBox at full output and control volume at the amp? Is there a happy medium where the amp is set so as not to blow the speakers, and then fine tuned with the MBox? If so, how many db of attenuation would be appropriate?
