Connection
The DME64N/24N must be connected to other DME64N/24N units as well as other audio equipment, according to the
audio system design.

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 DME64N/24N units as
well as other audio equipment. Audio signal transmission and reception will occur primarily via I/O cards installed in
the unit's I/O card slot(s). The DME24N has 8 channels of built-in audio I/O that can be used without installing
any extra cards.
2. Zone Control
Zone control signals control all DME64N/24N units and ICP1 control panels within the zone. There are two types
of zone control signals, as follows:
• Signals for communication between the computer or mixer that controls the entire area and the zone master
DME64N/24N.
• Signals for communication between the zone master DME64N/24N and other DME64N/24N within the zone.
The DME Designer application running on the area-control computer is used to send components and set
parameters as required.
3. Device Control
These signals provide communication and control between individual devices. Included in this category are MIDI
messages transferred between [USB] and [MIDI] connectors, GPI signals transferred between [GPI] connectors, and
remote head amp control signals handle via the [REMOTE] connector.
4. Word Clock
Individual devices that handle the same digital audio signals must be synchronized to a single word clock of the same
frequency. The DME64N/24N transmits and receives word clock via the [CASCADE IN] and [CASCADE OUT]
connectors, the [WORD CLOCK IN] and [WORD CLOCK OUT] connectors, and via I/O cards plugged into the
I/O card slots.
