DENON's AVR-2105 Direct Mode

Hi!


It's my first thread in this forum that i know and habitually read at some time... :)


It's just a simply question and i'll be very thankful if somebody could help me...


I bought a DENON 2105 AV Receiver a few weeks ago and now i decided to add a Rel Quake subwoofer to the system…


I’m having the hard task to configure the Sub and i have a question about the Direct Mode of the Receiver… It seems that it’s impossible in any mode to cancel the LFE signal in the respective output, better, there’s no mode that do it…


It's very common in this kind of equipment the Direct Mode do it (for hear a Stereo 2.0 audio source), and i waited that the 2105 also made it… More in this case, that i'm thinking to use the Hi-Level connection available from Quake...

I tried a lot of configurations but the LFE signal is always present…


I just want know if the functioning of 2105 is exactly this (and i must think in another solution), if i'm losting something reading the manual or, in last case, if there's a problem with my 2105…


Thanks a lot…


Sorry the English... :D

I'm sorry I can't help you with the 2105...but I have the Denon 2805. On that model, the Direct Mode removes the tone controls from the output. I also have a "Pure Direct" mode that also turns off all digital enhancements and the video circuits. It doesn't have an effect on the subwoofer.


Have you tried the various settings in the setup menu concerning where the LFE is output (such as subwoofer only vs. subwoofer+main)?


What is it you are hearing in the sound that you want to correct?

Hi... Thanks for your support...


Once i have the possibility to have the two connections simultaneously (Hi-Level and Low-Level), what is advised in REL manual to get the best bass quality, when watching movies there's no problem, but to hear 2.0 Audio Stereo it requires that i don´t have LFE (Low-Level connection) signal, or the SubWoofer receives a redundant bass signal that is perfectly audible ruining the sound...


It's an functioning that some equipment of this kind habitually has implemented in the "Direct", "Pure Direct" or some times also called "Source Direct" modes...


I've tried all in setup menu... Nothing solves the problem (if it is a problem)...


What i must know (for now) is if it's just like this or my equipment has some kind of malfunction...


Thanks again...

Wow, no, you shouldn't have both connected, just the line or the high-level.

Landroval, thanks for your support...


You must realise that the connection that i have to REL Quake is not the point...

Think about a good pair of main speakers, with a good Frequency Range and the possibility of intend that it all works as i said... There's a lot of AV receivers that do it... ;)

But let me tell you that i know some people that uses the configuration as i descrived and it works nice... One of the advantages of REL's subwoofers is exactly that... :cool:

Hi LandRoval ;)


My dear friend AC_DC is right, many people we now have that kind of setup with REL and MJAcoustic subs...


And they sound very good :cool:

Care to explain what's the point of having both high- and line-level? Which is used when and how do you select it (from the sub or receiver)?


If you have the high-level wires connected to the sub there is no way to have 2.0 sound. The sub will be always on and it will cut the low frequencies from the speakers (if it has a high pass output).

For a technical explanation, if you're really interested, i suggest a visit to REL's home page and maybe a download and reading of the REL Quake's manual, for example...


The point is that such as they say, the two connections simultaneously improves the bass in movies... But in 2.0, the Low-Level connection ruins the sound... And they advice to somehow, turn off the Low-Level connection...

This is the point... Many AV Receivers, in "Direct", "Pure Direct" or "Source Direct" modes would cancel the bass processing (LFE), among others things, and the Low-Level signal is naturally cancelled too... I wanted that 2105 do this but, it dont...


When we talk about 2.0 here is about que source... We know that the Sub will always receive the Hi-Level signal but this is what we want...

Think about the main speakers example above...


Thanks again...

I have a Denon 1604. I can't be sure that the 2105 is the same, but on the 1604, "direct" stereo generates a sub signal if your speakers are configured for small. If they are configured for large it does not. This isn't LFE. LFE is a separate channel for sound effects, which exists only for movies and other multi-channel input. In stereo what you're hearing from the sub isn't LFE: It's frequencies below the crossover, which are being allocated to the sub because you've told it your speakers are small.


If you want to use the sub the way Rel recommends, configure your speakers as large, connect the receiver's sub output to the Rel's low-level input, and connect the Rel's high-level cable to the speaker outputs together with the speakers. This will route the LFE through the low-level input, and use the sub to supplement the lowest sounds for everything else (i.e. non-LFE signals). By setting your speakers to large, you let the Rel do the crossover for non-LFE signals, which is what Rel recommends.


After doing half-way measures, I finally ended up setting my system up that way.

It will not cut the speakers because the Hi-level connection (Neutrik connection) of REL and MJ is in parallel with the speaker connection... it's not an output from the Sub...;)

You're right about the used nomenclature (LFE, and so one)... :eek:


Now... As i said, i tried almost everything, and this includes to put even all speakers in Large... The Low-Level signal is always present... :(


You're right about all other things... That is how it must function... But it does not...


My problem... The point... It's just like this... Have i a malfunction here!?


Maybe someone with a 2105 can test this and tell me something... PLEASE... :(

Hi!!!


I just want tell here that i found the solution... :D :D :D


It's necessary to access the Channel Levels while in Direct mode and turn the SW level down to -12db then OFF. The Denon's can store different Channel Levels for each mode....


I don't know about this... :eek: :eek: :eek:


Thanks for all...
