Signal Types
DME64N/24N audio system signals can be broadly categorized as follows.

1 Audio

The DME64N/24N will be required to send and receive audio signals to and from other DME series units as
well as other audio equipment.
Audio signal transmission and reception will occur primarily via the [INPUT] and [OUTPUT] connectors on
the DME24N.

2 Control signals within a device group

Device group control signals control all DME series devices in the group.
There are two types of device group control signals, as follows:
• Control signals between the computer and the group master DME series unit
• Control signals between the group master DME series unit and the other DME series units
You can use the DME Designer application to control the entire device group, such as sending components
to the devices and setting the parameters as required.

3 Control signals between devices outside the device group

These signals provide communication and control between individual devices.
Included in this category are MIDI messages transferred between [USB] connectors, GPI signals trans-
ferred between [GPI] connectors, and remote head amp control signals handled via the [REMOTE] connec-
tor.
