Russound D1650 オーナーマニュアル

This LED lights red when any zone is active or the amplifier is in standby mode.  

When a zone is powered on, the corresponding LED lights blue. When a zone 

is OFF, the LED is off (standby mode). If a short circuit happens on the speaker 
outputs, the LED will blink fast red and blue. 

The Bus 12VDC Trigger In is used to activate all zones that are using the Bus 

Input and disables other zone triggers or signal sensing on those zones when 
it is used. When the Bus 12VDC Trigger is used, all Bus-controlled zone LEDs 
will be blue and active. 

If the Bus Trigger In has 12V applied to it, only the 12V Bus Trigger Out will 

have 12V and the Zone Trigger Outputs will not. 

The bus line input is an optional input that can be used to connect a single 

source to multiple zones. The bus line output is a passive passthrough of the 
Bus Input and can be used to daisy chain the source to other amplifiers in the 
system.

The line audio input for each zone is a dedicated sensing input that will 

activate the zone when an audio signal from a source is present.

Sets the zone input to the Line Input or the Bus Input.

The minimum speaker impedance is 4 ohms for Stereo Mode and 8 ohms for 

Bridge Mode.

Left and Right gain controls independently adjust the sound level for each 

channel. When used in Bridge Mode only the Left control is used.

Turns the amplifier on/off. This switch does not disconnect the main power 

feed from the amplifier; to disconnect the main power, the power cord must 
be unplugged from the outlet.

Holds a replaceable fuse for AC power input connection. Refer to the 

specifications on page 10 for the fuse ratings.

Voltage is set with a selectable switch for 115V or 230V operation. The AC 

voltage input for the North American model is 115VAC at 60Hz (International 
model, 230VAC at 50Hz). This receptacle accepts a 3-prong IEC C14 type 
connector. A detachable 3- terminal power cord is included. The international 
models include power cords for the UK, Europe, and Australia.

The Zone 12V Trigger In is used to activate a specific zone. The Zone Trigger 

Out can be used to trigger other 12V devices. The delay and audio sensing are 
bypassed when the 12V Zone Trigger Input is used. When a Zone Trigger is 
active, the zone LED will be blue. If no voltage is present in the Zone Trigger, the 
Zone LED will be off. 

Standby delay can be adjusted to either 5 seconds, 5 minutes, or 10 minutes 

by using the DIP switches on the rear panel.  This delay is selectable per zone. 
When an audio signal is not present, the amplifier will automatically go into 
standby mode after the preset period of time. 

The default position for the DIP switch is a 5-second delay. The time delay is 

selected by moving the DIP switch to the down position. 

Note: One and only one DIP switch must be in the Down position at any time. 

Activating more than one DIP switch can lead to erratic audio operation.

The amplifier will go into Standby mode when audio signal or trigger is 

not present, and after the minimum delay time has timed out. The amplifier 
consumes 0.5 Watt or less current while in standby power mode.   

Sets each zone amplifier for stereo or Bridge mono operation.  

The D850 and D1650 amplifiers have been tested to work with all Russound 

autoformer-based volume controls.

In order to use the D-series amplifiers with auto-former based volume controls, 

please refer to the Tech Tip on the Russound Dealer Portal titled “Using a D-Series 
amplifier with autoformer-based volume controls”.

DIP switch configured for a  
5 second delay.
