KINKI   STUDIO

11

The EX-M7 is equipped with EARTH/GND optimization
scheme where you may utilize it to optimize the sonic

performance of the system.

Toggle the LINK/FLOAT switch (3) to engage or dis-engage
the power earth (2) with the chassis (1).

You may connect the EARTH (4) and/or GND (5) to the
upstream equipment to link the amplifier chassis to the

upstream equipment chassis. If the upstream equipment

does not come with a GND terminal, you may attach the
wire to the screw.

You may connect the EARTH/GND terminal to the ground

box too to experiment the differences. Enjoy!
