Introduction

The Russound D850 and D1650 multichannel digital ampliers are ideal for use in adding additional power in distributed audio systems. The D850 provides 8 channels of digital amplication while the D1650 provides 16 channels. The channels of both models are arranged in pairs to provide amplication for stereo zones. Both models provide an array of useful features such as bridge mode operation, global and independent zone triggering, audio sense circuitry with adjustable delays per zone, a Bus Input and independent line inputs per zone to meet a wide variety of applications and congurations.

Both models are rated at 50 watts per channel into 8 ohms and 80 watts per channel into 4 ohms. With the stereo/Bridge Mono switch in the Bridge position, channels are combined for a higher powered mono output of 160 watts into 8 ohms. The use of advanced digital amplication circuitry results in a smaller, lighter chassis, with cooler operation than our previous amplier models.

Thermal Protection

All Russound ampliers are designed with special circuitry to safeguard the amplier under a thermal overload condition. Thermal protection mode can only engage when the unit has been run at high volume for extended periods of time without adequate ventilation and/or when speaker impedances are below the minimum levels for the amplier.

Protection Circuitry

All Russound ampliers are designed with special circuitry to safeguard the amplier under a short-circuit condition. A faulty speaker can also cause a short circuit condition. The Zone LED will blink rapidly between Red and Blue when the Zone is in short circuit protection.

The amplier will auto-correct itself when the trouble condition has been removed. The amplier will then resume normal operation.

Rack Mounting

Both ampliers can be rack mounted using the included rack-mount ears and hardware to attach the ears to the amplier. The amplier will take two rack spaces with the feet removed.

BACK PANEL FEATURES

Power/Standby LED

This LED lights red when any zone is active or the amplier is in standby mode.

Zone LED

When a zone is powered on, the corresponding LED lights blue. When a zone is OFF, the LED is o (standby mode). If a short circuit happens on the speaker outputs, the LED will blink fast red and blue.

Bus 12VDC Trigger In/Out

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.

Bus Input/Output

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 ampliers in the system.

Line Input

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.

Line/Bus Switch

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

Speaker Outputs

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

Gain Controls

Left and Right gain controls independently adjust the sound level for each channel. When used in Bridge Mode only the Left control is used.

Power Switch

Turns the amplier on/o. This switch does not disconnect the main power feed from the amplier; to disconnect the main power, the power cord must be unplugged from the outlet.

Fuse Receptacle

Holds a replaceable fuse for AC power input connection. Refer to the specications on page 10 for the fuse ratings.

AC Input / Voltage Switch

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.

Zone 12VDC Trigger In/Out

The Zone 12V Trigger In is used to activate a specic 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 o.

Standby

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 amplier 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.

This illustration shows the DIP switch congured for a 5 second delay.

Standby Mode

The amplier will go into Standby mode when audio signal or trigger is not present, and after the minimum delay time has timed out. The amplier consumes 0.5 Watt or less current while in standby power mode.

Stereo/Bridge Mono Switch

Sets each zone amplier for stereo or Bridge mono operation.

Compatibility with autoformer-based volume controls

The D850 and D1650 ampliers have been tested to work with all Russound autoformer-based volume controls.

In order to use the D-series ampliers with auto-former based volume controls, please refer to the Tech Tip on the Russound Dealer Portal titled “Using a D-Series amplier with autoformer-based volume controls”.

TYPICAL SYSTEM CONFIGURATION

Both the D850 and the D1650 can be congured as the main amplier for an

audio distribution system or home theater system.

When used with an audio distribution preamp, each zone can independently drive one of several dierent sources by using each zone’s individual line audio inputs, or a pair of zones can be Bridge to create a higher powered zone.

When the D1650 is used as a home theater amplier, up to a 7.1 system can be supported. We recommend bridging the outputs for left, center and right and using stereo mode for both pairs of surround speakers. The remaining zone can be used for powering an additional area such as an outdoor zone.

BRIDGE MODE OPERATION

When the amplier is in Bridge mode operation, a single channel (the left) is used to produce a high power mono output. Use one channel pair to amplify the left channel by connecting the left audio signal to the L input of a channel pair, setting the Stereo/Bridge switch to "Bridge" and connecting the speaker as indicated below. Use a second channel pair for the right channel by connecting the right audio signal to the L input of a second channel pair, setting the Stereo/Bridge switch to "Bridge" and connecting the speaker as indicated below.

Wiring Instructions - Bridge Mode

For Bridged amplier operation, turn o the power to the amplier and connect an 8-ohm minimum load; follow the Bridge mode markings on the back of the amplier: Connect the negative lead (-) of the speaker cable to the R– terminal. Connect the positive lead (+) of the speaker cable to the L+ terminal. Set the Stereo/Bridge Mono switch to Bridge Mono, connect the Line In feed from a source to the Left Line In connection and restore power to the amplier.

USING SIGNAL SENSING

D850 and D1650 ampliers have a signal sensing feature which will allow the amp to turn on automatically when a signal from the source is “sensed”. This is useful if the source used with the D850 or D1650 amplier does not have a 12v trigger option.

There are many factors aecting the signal sensing of the D-series ampliers, and you can see a few recommendations and common scenarios listed below to help set the levels in the system to best optimize the signal sensing feature.

This information is most useful when feeding a variable line level signal into the amplier. If the source being used with the amplier is a xed line level, the amplier should turn on and o consistently. If not, then some of the troubleshooting tips below can help.

Keep in mind that the input signal will vary depending on the connected equipment. For example, in the case of using a D-series amp to add additional power to the zone outputs of an MCA multizone controller, the signal can vary from zone to zone, and even from source to source. In this case, the MCA has trim levels for both zones and source to even out the line level signals between the dierent zones and sources.

Tech Spec: The threshold rating for the signal sensing is 4 millivolts at 1 KHz RMS. This setting means that the sensing is sensitive to low signal levels. As a comparison, an average line-level signal is about 2 volts. (Variable line outputs will vary by nature, so these numbers are approximate.)

Common Practice: The way to get best results from Signal Sensing is to always have a “hot” input signal, or in other words have the Source Input signal turned up as much as possible, and to have the gains of the D-series amplier set to lower levels. There are going to be a wide variety of variables that will determine how “hot” the input signal is, and every install and every scenario will be dierent, however if the common practice is to have a the input signal turned up, and the amp gains set lower, the signal sensing should be reliable for any given situation.

Steps to follow:

1. Set the D-series amp gains all the way down.

2. Turn the Source volume level up. Depending on the Source, it is usually

best to set the source volume level to about 80-90%, to avoid clipping the signal.

3. Increase the gains of the D-series amp zone until the zone is at the loudest level you would safely recommend for the installation, i.e. louder than what the normal listening level would be.

4. Decrease the volume level of the Source down to normal listening level.

5. Turn the source o. The D-series amp will turn o after the set delay time.

6. Turn the Source back on. The D-series amp will turn back on.

7. See the troubleshooting section on page 11 if necessary.

TROUBLESHOOTING

Signal Sensing Problems

The D-series amp zone does not turn on:

• Check the input signal path

• Check the audio cable connections between the source and the amp

• If the source is a variable signal, make sure it is turned up

The D-series amp zone turns on, but not consistently

• Check the input signal level. It may need to be turned up

• Check the amp gain levels. They may be turned up too high

• Try connecting a tablet or smartphone with a headphone-to-RCA cable into

the amp zone input as a test

The D-series amp zone is always on

• Check for voltage issues and/or ground loops that could be aecting the

signal sensing circuit – See Below:

Ground Loops and Voltage Problems

Ground loops in the system with the D-series amp can the reliability of the signal sensing. Voltage introduced into the amplier by way of ground loops, or EMI-RFI noise, or other electrical noise on the power input, could be interpreted by the signal sensing circuit as an input signal. In this case, the amplier may not be able to tell the dierence between the actual signal and the electrical noise in the system, so the sensing ability of the amplier may be erratic or unreliable.

There are products on the market to help reduce electrical noise or ground loops, such as a Ground Loop Isolator, which can be used to block or reduce problems with the input signal path and make signal sensing more reliable.

In addition, there are even more considerations such as the length of RCA cables being used (shorter is better) and making sure the amplier and the sources are on the same power source to reduce ground loops and other electrical issues.

Test Example

A good way to test the amplier zone input and signal sensing is to use a portable device such as a tablet or phone. This type of test source is not plugged in to power therefore should not introduce any ground loop or electrical noise.

1. Remove the original source input cables and replace with a headphone-to-

RCA cable connected to the portable device.

2. Choose some music to play. An Internet Streaming source (e.g. Pandora) is

best because it will play a constant audio stream.

3. Verify that the amplier zone turns on and o reliably when connecting or disconnecting the RCA cable from the portable device according to the delay period timing that is congured for that zone.

4. If the signal sensing is still not reliable:

5. Disconnect all cables, including speaker connections and RCA connections.

6. Set the delay of Zone 1 to the shortest time setting.

7. Reboot the amplier.

8. Make sure music is playing on the portable device.

9. Connect the portable device to Zone 1 Line Input Only.

10. The Zone 1 amp should turn on.

LED Operation

Zone LED is blinking red/blue - This indicates a short-circuit condition on the wiring. Power down the amplier and verify all speaker wiring connections both at the amplier and at the speaker. Make sure no stray strands of wire are touching. When the wiring has been corrected, turn the amplier back on.

Zone LED is red - This indicates an overheating condition. Verify that the amplier is receiving enough ventilation. Separate the amplier from other components to allow more ventilation or add a cooling fan if needed.

Note: Both of these conditions will auto-correct themselves when the trouble condition has been removed. The amplier will then resume normal operation.
