DD-8+ Power
Owner’s Manual

5. Speaker Outputs
Provides connection for up to four pair of stereo speakers (eight speakers total) to the DD-8+. Connection
is provided via phoenix-type connectors that accept bare wire terminations. The connectors are grouped in
pairs with one connector each for output pair 1-2, 3-4, 5-6 and 7-8. Each pair consists of four wire terminations:
positive (+) and negative (–) for the Left channel and positive (+) and negative (–) for the Right channel. To
attach speaker cables to the phoenix connector, strip approximately ¼” (13mm) of insulation off of the end of
the positive and negative leads of the cable and insert the bare ends into the corresponding position of the
phoenix connector, tightening the screw terminals on top to secure the termination. Repeat this procedure for
each speaker.
NOTE: Use 16-gauge or larger speaker wire in order to ensure low-impedance connections between the
amplifier and speakers. Be sure to observe correct polarity when making connections to speakers: Positive
(+) leads to the Positive (+) terminals and Negative (–) leads to the Negative (–) terminals.
CAUTION: The speaker outputs on the DD-8+ are balanced (differential) and should
not be connected to any equipment that grounds the Negative (–) terminals.
6. Ethernet Port
Provides access to the Configuration Dashboard for system set-up including channel volume trim, input
assignment, equalization and other functions. See
Configuration Dashboard
instructions on page 14. After initial
set-up it provides connection to IP control/automation systems from Crestron, Control 4, Savant and AMX. See
Third Party IP Control Systems
instructions on page 26.
7. Trigger In/Out
Provides connectivity for remote 5-15VDC trigger signals used to activate and deactivate the standby mode of
the DD-8+.
The Trigger In and Out connections can be used to activate and deactivate the standby mode of the DD-8+
from devices such as remote control systems, preamplifiers or other external devices. The Trigger In and Out
connections are duplicated for both 1/8” (3.5mm) mono mini-plug and phoenix- style connectors. Use the
Trigger In for making connections to external control devices that will activate and deactivate the DD-8+
standby mode. The Trigger Out does not provide DC power on its own, but can be used for making Trigger In
daisy-chain connections to additional DD-8+ amplifiers or other components that need to mimic the DD-8+
power state.
NOTE: When a remote trigger is connected it will override the front panel standby button operation.
NOTE: Trigger connections are required if you plan to use the Green Mode feature with a third party IP
control system. When Green Mode is engaged, instructions from IP control systems will not restore the
amplifier to ON. Only a trigger signal will return the amplifier to ON status.
