Fitting the Feet and Base Plate

Power On Notes

When you have a working Mono Block you will notice that at turn on the mono block will make a humming sound that will
increase in volume for about 10-15 seconds and then completely go away - If the mono block is connected to speakers
but there is no input source then you will hear a hum after this initial period - its only when a low impedance source like a
pre-amp is connected to the mono block that the amplifier should go silent - no hum sound coming from the speakers.

Install the large rubber feet onto the base plate on the side
with the countersunk holes.
Use the fender washer on the bottom of the foot and the M4
16mm screw – on the other side of the base plate use a
serrated M4 washer and a M4 Nut.
Then place the base plate on the amplifier bottom and
secure with M3 6mm screws – stainless steel.
