Mixing

The main reason for having "Source number of channels" is because that setting must be used for output to most receivers if you want the receiver to do the upmixing. If you are sending PCM over HDMI then I think you need to use 5.1 or 7.1, but the receiver can still upmix the actual channels being used.

Here is what you need to ask? Channels Is JRiver or the receiver going to handle upmixing, speaker setup, and bass managment? If the answer is "receiver," then you use "Source number of channels." Otherwise, you usually need to select the number of physical channels you have for output.

Mixing Do I want upmixing and if so, do I want JRiver or the receiver to upmix? If you don't want upmixing or want it done by the receiver, then you select "No upmixing or downmixing." Otherwise, you select "JRSS."

There are primarily five options for users:

• 1. Don't upmix, but let JRiver handle speaker setup and bass managment
• 2. Let JRiver upmix and handle speaker setup and bass management
• 3. Let JRiver upmix and let the receiver handle speaker setup and bass management
• 4. Let the receiver upmix (or not) and handle speaker setup and bass management
• 5. Let JRiver upmix and handle bass managment and some speaker setup and then let the receiver handle more speaker setup and more upmixing (this is used for height channels)

Speaker setup Setting the proper distance and gain for each speaker Bass Management Setting whether speakers are large/small and setting the crossover frequency. Frequencies below the crossover are sent to the subwoofer and the channel is created if it doesn't already exist. If it does exist, then bass from other speakers is routed to the subwoofer channel.

1. If you don't want to upmix, but want JRiver to handle speaker setup and bass management, then . . .

• You set Channels to the number of physical channels you have available
• You set Mixing to "No upmixing or downmixing."
• You use Room Correction to handle speaker setup and bass managment (this method is easy and is more intuitive than how a receiver does it). You can even add a subwoofer channel for a stereo source.

2. If you want JRiver to upmix and handle speaker setup and bass management, then . . .

• You set Channels to the number of physical channels you have available
• You set Mixing to "JRSS"
• You use JRSS to mix a bass channel for stereo sources using the Subwoofer setting in Output Format (mains are still fullrange) and use Room Correction for speaker setup for all sources and bass managent for sources that already include a subwoofer
• You set the Subwoofer to "Silent (use Room Correction to redirect bass to subwoofer) and then you use Room Correction to handle speaker setup and bass management for music and movies

3. If you want JRiver to upmix and let the receiver handle speaker setup and bass management, then . . .

• You set Channels to the the number of physical channels you have available
• You set Mixing to "JRSS"
• You use the receiver for speaker setup and bass management

4. If you want the receiver to upmix (or not) and handle speaker setup and bass management, then . . .

• You set Channels to "Source number of Channels"
• You set Mixing to "No upmixing or downmixing"
• You use the receiver to upmix and handle bass management
• You set Mixing to "JRSS"

5. If you want to let JRiver upmix and handle bass managment and some speaker setup and then let the receiver handle more speaker setup and more upmixing

• You set Channels to the number of physical channels you have available
• You set the Subwoofer to "Silent (use Room Correction to redirect bass to subwoofer) and then you use Room Correction to handle speaker setup and bass management for music and movies
• You set the receiver to 9 or 11 channel mode for heights and it will upmix the height channels.
