1 [AC IN] Connector
This is the devices three-pronged AC power connector.
Connect to the AC mains using the supplied AC power
cord. See “Preparation” on page 8 for details.
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.
3 [GPI] Connector
This Euroblock connector provides access to the units 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 0V or 5V. See “GPI Connection” on page 32 for
connection details.

NOTE
Use the supplied AC cord clamp to prevent accidental
disconnection of the AC power.
NOTE
When connecting to two-prong type AC mains outlets use the
supplied plug adaptor.
NOTE
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.)
NOTE
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.
