Also just discovered the digital crossover allows true bi-amping with the onboard crossover able to direct frequencies to specific drivers in a bi-amp configuration... WOW!
My speakers have bi-amp terminals with each drivers crossover on its own dedicated board so it would be really simple to bypass the built in cross overs and run true bi-amp with digital crossover done in the Onkyo.

Has anyone tried this digital cross over feature with bi-amp or bi-wire configurations?
From 818 instructions.
Digital Crossover provides a separate routing system by splitting the audio signal into separate frequency bands optimized for each speaker driver. It provides a fine, three- dimensional sound field that extend each driver's performance to the uppermost.
With its built-in time alignment function, this system also adjusts the sound shifting that occurs when there is a physical offset between sound drivers. At a digital processing level, it corrects this offset by delaying the related audio signal.
Although this function is meant for speakers without crossover network, it can also be used with bi-amped speakers.
In this case, set the crossover network on the AV receiver as the speakers' built-in network frequency is not used.
250Hz, 320Hz, 400Hz, 500Hz, 630Hz, 800Hz, 1000Hz, 1250Hz, 1600Hz, 2000Hz, 2500Hz, 3200Hz, 4000Hz, 5000Hz
Output Band for Test
High + Low, High, Low:
Select the output for the audio signal.
With this setting, a frequency band near the specified crossover frequency is output by both tweeters and woofers. Based on the frequency selected for Crossover, the cutoff frequency of the low-pass filter (LPF) will be set to 1/3 octave up and that of the high-pass filter (HPF) to 1/3 octave down. Example: With a Crossover of 3200Hz, the cutoff frequency of the woofers' LPF will be 4000Hz, and the tweeters' HPF will be 2500Hz.
High Level, Low Level
-6.0dB to 0.0dB to +6.0dB in 0.5 dB steps
With this setting, you can set the volume of tweeters and woofers.
High Phase, Low Phase
With this setting, you can adjust the phase of tweeters and woofers.
High Distance, Low Distance
0inch(0.0cm) to 12inch(30.0cm) in 1 inch(2.5 cm)
With this setting, you can adjust the virtual position of tweeter and woofer units.
Adjusting High Distance virtually shifts woofers behind tweeters. Adjusting Low Distance virtually shifts tweeters behind woofers.
