kenot la how can AVR 789= AVR 1909
Q. What is the difference between the 789 and the 1909, I was looking at their specs on the Denon website and they look identical?
A: Denon puts out two parallel receiver lineups, with four-digit and three-digit model numbers. The four-digit models are generally sold by high end stereo shops and custom installers, and the three-digit models are the "consumer" version sold in retail outlets like Circuit City and Fry's.
However, there is ZERO difference in terms of power, specs, sound quality, build quality, etc. between the two lines. Denon has been doing this for years, it is exactly analagous to the Yamaha HTR and RX-V parallel receiver lines.
There will usually be one or two minor differences to differentiate the three-digit and four-digit models. There is typically a slight cosmetic difference between the two lines, and different remotes.
In the specific case of the 1909 vs. 789, the only differences (besides the cosmetics) is:
1. the 1909 includes a small, second remote intended for Zone 2 operation, and
2. the 1909 has a plug on the back labeled "RF/RC 2WAY", next to the Sirius plug. The function of this plug is to allow you to hard-wire a two-way RF remote controller (sold separately) to use in a different room. See page 20 of the manual for a detailed explanation.
In all other respects, the 1909 and 789 are IDENTICAL.
AVR 1909 (aka 789) vs AVR 1910 (aka 790)
Comparison of 1909 vs 1910 from Denon website:

http://www.usa.denon.com/AVR1910_Large_Back.jpgStraight to the point:
- 1910 gets an extra HDMI input (4 vs 3), but drops some legacy inputs (only 2 component video, and only 1 s-video which can ONLY be used with Denon ipod dock control as per NOTE on pg 9 of manual)
- 1910 gets new ABT video processor which allows for HDMI > HDMI scaling up to 1080p (pg 34 of manual)... but still no OSD overlay.
- 1910 weighs 1.8 lbs less (23.6 vs 25.4)... but has identical power specs (90W x 7 @ 0.08% THD) so judgement withheld for now as to whether the 1910 has less "real" power.
- 1910 gets Dolby PLIIz with the ability to reassign the SURR.BACK to FRONT HEIGHT for alternative 7.1 setup.
That's about it! They are almost identical in most other respects.
Other relatively minor functional differences:
1. The new video processor apparently also allows the 1910 to handle 1080p component > HDMI conversion (pg 9 of the manual no longer has a footnote specifying this restriction, and even specifically references 1080p component coming out at 1080p). However, the OSD looks basically the same and the overlay restrictions (only on s-vid / composite) are unchanged; apparently you need to step up to 2310/890 level for a real GUI w/ overlay.
2. There are now SEVEN discrete video names to which you can assign inputs: DVD, HDP, TV, CBL/SAT, VCR, DVR, V-AUX (which shares front panel inputs). This means you can hook up more devices with discrete name access (no need to "stack" inputs) and actually use all six hi-def inputs (4 HDMI + 2 component) without needing to borrow the "V-AUX" name from the front panel inputs. Note, however, that there is now only one "audio only" input name (currently "CD" is the only audio only input name).
3. Dynamic EQ gets a "Reference Level Offset" which can be accessed in Surround Parameters; note that, functionally, it is identical to adjusting the "Source Level" for an input, but the easy access in "Surround Parameters" menu means you can make "bass taming" tweaks on the fly more easily.
4. HDMI Control gets a "Standby Source" setting (see pg 28) which allows you to specify which HDMI input is "passed through" to your TV. No need to remember to switch inputs before you power down!
5. The evil two-sided flip-door remote lives on However, there is now a discrete "Source Select" button on the front (the big button under the D-Pad, used to be the "Restorer" button) which cycles through your inputs (so you don't have to go to the hidden flip door to select a source that didn't make the cut for the front panel).
6. Direct mode "purists" rejoice! You no longer have the option to use Audyssey at all with any Direct mode (regular, pure, or multich) according to the chart on pg 58 of the 1910 manual.
7. The "LPF for LFE" setting has moved from the "Crossover Freq" menu and now lives in the "Bass Setting" menu (pg 26 of manual). This should reduce some confusion (e.g. it's not a crossover!) although the wording in the Denon manual makes it sound like it's an HPF for the subwoofer, and not just the LFE channel.
8. MANUAL EQ adjustment has moved into the "Surround Parameter" menu so it can be accessed on-the-fly more easily (pg
9. The Volume Control can now be optionally set to "absolute" or "relative" value (see pg 30 of manual). So anyone who hates the "negative numbers" style of volume, you can set it to go from 0 to 99!
10. There is a "Zone Rename" function (pg 31) so you can rename "Zone 2" to say "Patio" or whatever.
11. They have apparently removed the HDMI options for "Color Space" and "RGB Range". Ostensibly these were just confusing people and it is now essentially stuck in "auto" mode for color space.
12. New, streamlined front panel layout (fewer buttons, menu/d-pad/return button cluster moves to the middle)
