GAIN CONTROL
Located in the preamp section on the side panel of the amplifier is the gain control (marked level). This control allows you to match the input level of the amplifier to the output level of your source unit or signal processor. Matching the input can be accomplished in three simple steps:
1.Turn gain control all the way down.
2.Turn on the source unit and adjust to 2/3 of max volume.
3.Adjust the gain control until desired volume is achieved without audible distortion
Remember that the gain control is not a volume knob. Ignoring the three steps above may leave you with damaged speakers and possibly a damaged amplifier.

Gain
Control
If you are bridging the two BMF600D or BMF1000D's together, only the gain control on the "Master" amplifier is adjustable. Use the same three steps to adjust the gain.
POWER AND PROTECTION
On the power and speaker panel of the amplifier are two LED's. These LED's indicate either power "on" or protection modes.
Green LED: This LED illuminates when the amplifier is powered up indicating normal operation.
Red LED: This LED illuminates when the amplifier goes into protection. This indicates a problem with the system in relation to the amplifier connected to it.
