DD-8Power Amplifiers

Basic Operation

NOTE: It is possible to have a situation where Signal Sense cannot function if the Power Save feature is also used and has been activated. For example, Signal Sense will deactivate channels without signals after 30 minutes. If all channels are deactivated, Power Save will be enabled after an additional 30 minutes of no signal. During that additional 30 minutes, Signal Sense will continue to function and will activate any channels that receive an incoming audio signal. Once the Power Save standby mode has been enabled, Signal Sense will not be able to function requiring the DD-8 to be turned on again via the front panel standby button.

NOTE: In some cases, audio signals with very low output may not activate the Signal Sense circuitry in a timely manner or in some cases, not at all. This could occur with music or audio that begins with very soft or quiet passages or with abnormally low-voltage source signals. If the Signal Sense circuitry will not reliably activate channels within the DD-8, it is suggested to use either the front panel standby button or trigger input control for proper operation.

10. 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.

To install a trigger cable:

PP Power the controlling source and DD-8 amplifier off.

PP Connect the trigger cable to the controlling source and the DD-8 amplifier.

PP After the connections are made, power on the controlling source and the DD-8 amplifier. After the source unit is fully powered up, the LED power indicator on the front of the DD-8 should be lit BLUE.

PP Verify the trigger is working by putting the source unit into standby mode. The DD-8 amplifier after a short delay will also go into the standby mode and the power indicator will light up RED.

PP Once you have verified that the trigger cable is working, only use the source unit to power on and off your DD-8 amplifier.

WARNING: When installing the trigger cable, never have the controlling source or DD-8 amplifier powered on. Doing so will cause the trigger device to work improperly and could cause damage to both the source and amplifier.
