STATUS
LED indicates the overall system status (Green = OK; Red =
ERROR).

POWER
connection accepts the included IEC power cable.

ULTRANET IN/OUT
connections offer proprietary ULTRANET networking
capabilities through by using CAT5 cables with RJ45 connectors. ULTRANET
allows the user to transmit unidirectionally up to 16 independent channels
of 24-bit audio. Up to 7 devices can be connected in series on a single
ULTRANET cable. DM8008 uses ULTRANET to connect with the main
DM8000 unit.
(4)
OUTPUTS
section offers 8 output channels of balanced analogue audio
using Euroblock connectors.
(5)
MODE
switch determines whether the DM8008 outputs channels 1–8 or
9–16.
Mains power
Each mains inlet should be sourced from its own separate
wall-mounted mains outlet socket. Otherwise, both mains
sources must be suitably distributed so as to meet local
safety regulations.
4. Analogue Audio Connectors
To ensure the correct and reliable operation of the equipment, only high quality
balanced, screened, twisted pair audio cable should be used. XLR connector
shells should be of metal construction so that they provide a screen when
connected and, where appropriate, they should have Pin 1 connected to the
cable screen.
DM8008 uses Euroblock connectors for all analogue audio connections.
The following graphics offer guidance for correctly wiring common audio
connectors (XLR, ¼", RCA) to the Euroblock connections.
