1 [AC IN] Connector
This is the device's three-pronged AC power connector.
Connect to the AC mains using the supplied AC power
cord. See "Setup" on page 18 for details.
NOT E
Use the supplied AC cord clamp to prevent accidental
disconnection of the AC power.
NOT E
When connecting to two-prong type AC mains outlets use the
supplied plug adaptor.
Even when the power switch is turned off, electricity is
still flowing to the product all the minimum level. When
CAUTION
you are not using the product for a long time, make sure
to unplug the power cord from the wall AC outlet.
2 Ground Screw
The supplied power cable has a three-prong plug that will
ground the unit when plugged into an appropriate three-
prong type AC mains outlet. When connecting to a two-
prong type outlet that has a ground screw, use the supplied
AC plug adaptor and connect the adaptor's ground lead to
the ground screw. When connecting to a two-prong type
outlet that does not have a ground screw be sure to connect
the DME64N/24N ground screw to a confirmed ground
point. Proper grounding can significantly reduce hum,
noise, and interference, while stabilizing phase and
imaging.

N OTE
Make sure that the device is securely grounded to a single ground
point (e.g. either via a three-prong AC connection, or via the
ground screw.)
N OTE
Connect the device to only one ground point.
Connecting the device to more than ground point can result in
ground loops that can cause increased hum and noise.
3 [GPI] Connector
This Euroblock connector provides access to the unit's GPI
(General Purpose Interface) interface for transfer of control
signals to and from external equipment. The DME64N
provides 16 channels of GPI input and output, while the
DME24N provides 8 channels. Each input channel has an
IN terminal and a +V terminal. Output channels each have
an OUT terminal and a GND terminal. The open voltage
at the +V terminal is 5V, while the IN terminal detects
voltage changes from 0V ~ 5V. The OUT terminals output
either signal "L" or "H" at a TTL level.
See "GPI Connection ([GPI] Connectors)" on page 33 for
connection details.
