My Denon died, I was using it as a pre amp. So as of 90 mins ago, the Oppo 105 is now going straight to the Anthem MCA50 amp.
How can I have my speakers set to large and still get the sub to work?
I am listening to Cds at the moment and unless I go small there is no sub.
My speakers are well big enough to handle full range and I'm sure I read somewhere this was possible.
Also, do you think there may be an upgrade to create a 5ch stereo mode or all channel stereo instead of Neo6?
That's one difference I've found already that sounded better with the Denon.
Thanks in advance.
I'd be surprised if there were additional feature upgrades to the 105 at this point. OPPO has done late in life upgrades in the past, but they are always a surprise.
The normal way to get Sub bass with full range speakers would be to set the speakers to SMALL and set a lower Crossover frequency. Keep in mind that Crossover rolls in over about a factor of 2 in frequency. So if you set Crossover to say 60Hz, that means you are saying your speakers are good for quality bass output, at volume, all the way down to 30Hz. Sub Boost, applied external to the player, should be +15 dB in this configuration, so that the Sub output is matched to the main speakers.
If you really want Double Bass -- bass from BOTH the Left/Right front speakers and the Sub you CAN do that, but it is not really correct sound reproduction:
1) Wire the Dedicated Stereo Analog RCA pair and also the Subwoofer RCA jack from the multi-channel set.
2) Set Stereo Signal to DOWN-MIXED STEREO. This means the Dedicated RCA pair will get a full range signal.
3) Meanwhile set LF/RF SMALL in the multi-channel Analog Speaker Configuration (even though they are not wired). This enables Crossover to the Sub out.
4) Select a Crossover frequency. Steered bass will come out on the Sub jack even as full range is coming out on the Dedicated pair.
5) Adjust the volume knob on your Sub to get the blend you want. Since you are doubling the bass output, there is no "correct" answer for this. It will be a matter of taste.
