Q: I don't have an HDMI capable AVR and I plan to use the 5.1 analog outputs on the player. How do I set this up?
A: It's very similar to what you've probably done before. You will need 6 RCA cables coming out of the player to a 6 channel analog input on your AVR. Preferrably, and to take full advantage of the higher resolution HD audio in the A1, your receiver should process in the analog domain only. This may, however, mean that you'll have fewer options for adjustment on the AVR. Typically, you will have independent level adjustment for all 6 channels but no bass management capability. The bass management will have to be done in the A1.
You need an SPL meter. Go to the A1 setup menu under audio, then 5.1 audio to access the 5.1 audio setup menu. Set your speaker sizes and distances accordingly. Set the desired crossover frequency. I would reccommend using an alternate source for test tones such as those found on THX optimizer tracks. The A1 test tones are harder to use and may not be as accurate. Start out with all levels at zero on the A1. Set the SPL meter to 70 db. slow response, C-Weighted and try to balance all channels to the 0db mark. Ideally, keep the overall levels as high as possible on the A1 and use the AVR channel level adjustments to balance everything. You may have to consider raising the gain on your sub to get adequate levels from the LFE or .1 channel. This may take some patience and experimentation but it's worth it.
You may need to then go back and readjust your prior levels on the AVR for digital inputs if necessary. If you had to change the gain on the subwoofer itself, leave it alone at this point and compensate by adjusting the levels on the AVR (for digital inputs only).
At the time of this writing, there are at least two known problems with the bass management on the 5.1 analog outputs:
#1)It seems the overall LFE level is about 10 db lower than the other channels.
Tip: To maximize the overall LFE output level, set all speakers to Large.
#2)The LFE will not re-route to the speakers designated Large if you disable the sub output in the A1 setup menu.
There is a workaround for #2 that can be found here:LFE routing workaround

#2 should only be an issue if you don't use a subwoofer in the traditional fashion. #1 will make balancing the LFE to the other channels a little more difficult but it should still be possible with most standard 5.1 configurations.Tips for boosting analog LFE

It's probable that these issues will be corrected or improved upon by firmware upgrade from Toshiba soon.
Correctly setup, the 5.1 analog outputs should provide the best the player has to offer but may take a little more effort than if using HDMI for audio.
