Thanks :-) - Niko Bentroudi Sat, 14 Nov 2009 15:51:11 +0100 http://www.hometheaterhifi.com/receivers/485-a-secrets-receiver-review.html#comment-2327 Help!! I have spent hours trying to set this receiver up. Missed the HDMI problem initially, but not have optical audio set up. Still no audio. Any suggestions? - Bruce West Fri, 30 Oct 2009 08:10:25 +0100 http://www.hometheaterhifi.com/receivers/485-a-secrets-receiver-review.html#comment-1650 Michael- Why not run the optical audio directly from the PS3 to the receiver? That should give you Dolby Digital and DTS out of the PS3. - Gabriel Lowe Sat, 07 Mar 2009 21:02:07 +0100 http://www.hometheaterhifi.com/receivers/485-a-secrets-receiver-review.html#comment-1575 Hi I ran the Audessy EQ autosetup on my denon avr-689 and its hanging at "storing" Kind of scary, quite a bit of money to be simply lost. :| - Joshua Sun, 22 Feb 2009 16:13:00 +0100 http://www.hometheaterhifi.com/receivers/485-a-secrets-receiver-review.html#comment-1574 Unfortunately I did not know about the HDMI audio problem before I bought this at Circuit City close out sale - so I am screwed. For my PS3, I ran the optical audio out of my Sony TV to the reciever. I hear sound out of thh TV, Front right & left speakers, center channel, and subwoofer; but not our of my rear surround sound. Any ideas how I can get it to work out of the rear surround sound speakers?

As for your second question, theoretically, since the bitstream or PCM data passed along the cables are 1's and 0's, there should be zero difference in those transports. Obviously HDMI has more bandwidth, and thus can carry more information, but for the good old Dolby Digital, DTS, and stereo PCM signals, they should all sound the same. - Gabriel Lowe Fri, 30 Jan 2009 18:40:01 +0100 http://www.hometheaterhifi.com/receivers/485-a-secrets-receiver-review.html#comment-1368 In addition to my previous question, I also wanted to find out how much difference is there in sound between optical / digital coax and HDMI. How noticeable is the difference? - IQ Fri, 02 Jan 2009 12:10:45 +0100 http://www.hometheaterhifi.com/receivers/485-a-secrets-receiver-review.html#comment-1347 Could you please suggest on a comparable receiver in the same class & price range that does decode the HDMI audio? Thanks - IQ Tue, 30 Dec 2008 11:18:46 +0100 http://www.hometheaterhifi.com/receivers/485-a-secrets-receiver-review.html#comment-1237 Dillon- that is a fair point about their site. It is not the easiest thing to find. If you go to the specifications for a given receiver, and then look under the "connectivity" section, you can see whether it supports HDMI audio. - Gabriel Lowe Sat, 15 Nov 2008 21:27:03 +0100 http://www.hometheaterhifi.com/receivers/485-a-secrets-receiver-review.html#comment-1234 Can you clarify the terminology that Denon uses for the receivers that do HDMI audio, as the website is very vague. - Dillon Sat, 15 Nov 2008 07:56:14 +0100 http://www.hometheaterhifi.com/receivers/485-a-secrets-receiver-review.html#comment-1219 In the Audyssey menu, with Audyssey enabled and no other options selected, there is a high frequency rolloff to eliminate some of the harshness in movie soundtracks. When you select "Flat" from the Audyssey menu, the high frequency rolloff is eliminated. This is why it is generally recommended that when you play music through a receiver or SSP with Audyssey, you select the Flat option. Frankly, I see the rolloff in the Audyssey as a duplication of Cinema EQ, which also rolls off the harsh sound track high frequencies. - JEJ Mon, 10 Nov 2008 12:19:27 +0100 http://www.hometheaterhifi.com/receivers/485-a-secrets-receiver-review.html#comment-1218 I thought I was clear that you can only use the Audyssey settings (flat, Audyssey, or L/R bypass) if you DO calibrate using the Audyssey system. As for the flat and Audyssey target curves, your assessment of what these are optimized for is not exactly correct. Optimizations are for room correction overall, not the type of media playing. Taken directly from Audyssey's website: What target curves does MultEQ use? Contrary to popular belief, a target curve that is flat from 20 Hz to 20 kHz is not always the one that will produce the correct sound. There are several reasons for this including the fact that loudspeakers are much more directional at high frequencies than they are at low frequencies. This means that the balance of direct and room sound is very different at the high and low ends of the frequency spectrum. The Audyssey target curve setting makes the appropriate correction at high frequencies to alleviate this problem. A slight roll-off is introduced that restores the balance between direct and reflected sound. The Flat setting uses the MultEQ filters in the same way as the Audyssey curve, but it does not apply a high frequency roll-off. This setting is appropriate for very small or highly treated rooms in which the listener is seated quite close to the loudspeakers. It is also recommended for all rooms when the receiver is in THX processing mode. This allows THX re-equalization to operate exactly as it was intended. The Front setting uses the MultEQ filters that were calculated for the entire listening area, but it does not apply any filtering to the front left and right loudspeakers. The average measured response from the front left and right loudspeakers is used as the target curve for the remaining loudspeakers in the system. The subwoofer in this case is equalized to flat as is the case for all the settings described above. In some products, there is a Manual setting. This is a traditional parametric equalizer that does not use the MultEQ filters or measurement process at all. - Gabriel Lowe Mon, 10 Nov 2008 11:24:43 +0100 http://www.hometheaterhifi.com/receivers/485-a-secrets-receiver-review.html#comment-1215 I think you have misrepresented the differences between the "Audyssey" and "Flat" choices - both of these settings use the results of the calibration. The "Audyssey" choice is optimized for movies and the "Flat" choice is optimized for music. - Rick Brown Mon, 10 Nov 2008 08:00:50 +0100
