1068 Bass management question

[InTheRed]

Again, I'm pretty close to getting a 1068/1075, but just wanted to clarify the bass management capabilities for the analog 5.1 inputs.

As far as I understand it, if it is set to small speakers with the sub set to 'on', then everything below 100hz will be sent to the sub (is this frequency adjustable?). If the speakers are set to large with the sub 'on' then you get the double bass issue. Is this correct?

I have Snell large bookshelf speakers, so I'm in the middle ground, and would usually like to have the sub working for me, but usually listen with the large speaker setting. Is the 'large speaker/small speaker' setting a universal one or assignable by input like some of the other bass management features?

The "bass-doubling" was only an issue in the older model, the 1066. The new 1068 does not have this "feature"/issue (as default). All bass management should be done in your player. You can re-create the "bass-doubling" using what Rotel refers to as LFE REDIRECT but it is entirely user selectable.

When the MULTI INPUT source is selected on the INPUT SETUP menu, the available options change to reflect the fact that these inputs are
direct analog inputs and bypass the RSP-1068’s digital processing. The INPUT, CINEMA EQ, and DEFAULT MODE options are not available since these are all digitally implemented features. The VID INPUT, INPUT LABEL, and 12V TRIGGER options are still available and work as
described on the previous menu. One additional option, LFE REDIRECT, provides an alternative bass management configuration. Typically, the eight channels of the MULTI INPUT are configured as pure analog bypass signals, going straight from the inputs to the volume control and the preamp outputs, bypassing all of the digital processing. There are no crossovers and no bass management; therefore, whatever signal goes into the subwoofer channel will be sent to the subwoofer preamp output.
This configuration may not be ideal for multichannel systems configured with high-pass speakers, redirecting bass to a powered subwoofer.
An option, called LFE REDIRECT, sends the seven main channels directly to the outputs as usual. In addition, it takes a duplicate copy of these seven channels, combines them into mono, and routes them through a 100 Hz analog low-pass crossover to the subwoofer preamp output. This creates a summed mono subwoofer signal, derived from the seven main channels of the MULTI INPUT. Use the LFE REDIRECT off for the pure analog bypass configuration. Use the LFE REDIRECT on setting to derive the mono summed subwoofer output.

Thank you so much for providing the info. That clears it all up. The board rocks.

Did you get that info from an online manual or other detailed source? I'd love to see that if you have a link. Sometimes I find Rotel's marketing materials lacking in useful detail.
