"The" Onkyo TX-SR875 Thread - Page 202

post #6031 of 6042
Hi guys. I need your help about proper settings of frequency of my speakers with Onkyo TX-SR 875 receiver.

My front speakers are JBL ES90 and technical specification of these speakers is:

Power Handling (Recommended) 110W
Power Handling (Peak) 440W
Sensitivity (2.83V@1m) 91dB
Crossover Frequencies 500Hz, 3kHz – 24dB/octave; 12kHz – 18dB/octave
Maximum Recommended Amplifier Power 225W
Frequency Response 36Hz – 40kHz
Nominal Impedance 8 ohms

My central speaker is JBL ES25C and technical specification is :

Power Handling (Recommended) 75W
Maximum Recommended Amplifier Power 150W
Crossover Frequencies 3000Hz – 24dB/octave; 12000Hz – 18dB/octave
Sensitivity (2.83V@1m) 90dB
Frequency Response (-3dB) 80Hz – 40kHz
Power Handling (Peak) 300W
Nominal Impedance 8 ohms

My surround speaker is JBL ES20 and technical specification is :

Power Handling (Recommended) 60W
Nominal Impedance 8 Ohms
Maximum Recommended Amplifier Power 125W
Frequency Response (-3dB) 60Hz – 40kHz
Crossover Frequencies 3300Hz – 24dB/octave 12000Hz – 18dB/octave
Power Handling (Peak) 240W
Sensitivity (2.83V@1m) 86dB

My subwoofer is JAMO E7SUB and his technical specification is:

Impedance (Ohm) 22k
Woofer (mm/in) 254 / 10
Weight (Kg/lb) 21/46,3
Frequency Response (Hz, +/-3dB) 40 - 150
Rated output (W) 675 peak
Overall Dimensions (mm/in, HxWxD) 375x375x375/14,76x14,76x14,76

I would like to know how to adjust adequate frequency for each of these speakers that I mentioned above(front, central, surround and subwoofer) in the Onkyo receiver TX-SR 875?

All suggestions are welcome. Thank You.
And another question, how in onkyo TX-SR 875 change impedance from 4, 6 ohms to 8 ohms as all JBL speakers works at 8 ohms?
I currently have option in onkyo 875 to change the 4 and 6 ohms.Does not offer me the option to switch to 8 ohms.
Sorry for my bad English.
Thank You in advance

I've an Onkyo TX-SR875 for many years - it was a new model when I bought it.
Screen is attached via HDMI only.
I'm using almost only HDMI inputs (all 4 taken), and 1 component input (WII). I've not used the WII in years, but it used to work just fine - not so anymore.

All the component and composite inputs seem to have gone bad somehow.

The input is seemingly lacking the needed synchronisation and the image is shaking sideways all over.
I've tried hooking up the WII to all 3 component inputs and to the composite input of AUX2 as well, all the same result.
I've also tried all 3 output modes of the WII, no joy.

If I hook up the WII directly to the TV I get a perfectly good image (but no sound, my screen has no speakers at all).

So it's not cables nor the WII itself.

I might over the years have changed some setting that is causing this - but I've tried canging many of them and nothig seems to help at all (passthrough or upscaling all seems to make no difference at all).

Any settings I need to double check or any easy repair options for the Onkyo ?

I'm located in Europe should that matter (and the Onkyo is a EU model).

Hi everyone,

can some one please provide me a link or an copy from the "xx5_Onkyo_UpdatesISO.zip" file? As far as I understand, it's handy for fixing the EEPROM error. I tried google and searched this board, but didn't get a working copy.

*edit: I would like to fix the EEPROM Error according to this post: The Onkyo/Integra direct firmware updates. My Problem is, I just can't find any of the needed files. The receiver is a few years old now and forgets it's settings every time the power goes down. It's actual Firmwares are: MAIN: 1.07 and HDMI 1.01

Can anyone tell me, which are the newest firmwares and where to get them and perhaps the old 1.05 main fw?

Thank you very much in advance!

Hi Tspeer, your image includes the TX-SR875 ( 1.09/08Y19A ) firmware?
post #6036 of 6042
I believe the 1.08 is as high as it goes. There is also a DSP update and an HDMI update.

They are all good starting points and solve most problems. I do not know what the 1.09 is suppose to fix over the 1.08.

Have any of you folks used your 875 as a 7 channel amplifier for a newer pre/pro?

Because I have a last gen Panasonic plasma (no 4k) and a 7.1 home theater, I am thinking that an integra 80.2 or onk 5508 will better feature match my components than my 875, but I do not have the resources to get a pre/pro AND a new 7ch amplifier at this time. I got my 875 new in 2007 and particularly since getting some active cooling for it, it has been a titan.

It occurred to me that the 875 might act as a perfectly adequate (and THX Ultra 2 certified) amplifier for the time being.

Does anyone have experience with this? Obviously I want the 7 analog channels coming out of a nice pre/pro to bypass all signal processing in the 875, and I have heard that is possible except for volume control. How would one go about eliminating all signal processing from that source (I am assuming there is a specific sound mode for this, maybe a menu setting?), and if the volume cannot be eliminated, what volume should I set on the unit to interfere as little as possible? Is it plausible to expect a setup that works as well or better than the 875 has worked by itself?

I would really appreciate hearing about people's experiences.

My TX SR875 was in storage for 4 years and today upon hooking it up noticed there was no output from the Center or Surround L/R channel. I cannot get a test tone either. Tried a reset to no avail. Speakers work fine so that not the issue. Front L/R and Surround Back L/R work fine so it is the other two channels were I am having issues. Any ideas what it could be as I went through the speaker setup and settings are all correct?

Surprise, especially me... It is now working.

I ran it last night and got it fairly warm but still had the issues.

This morning I checked for obvious signs and checked the fuses by pulling them out and placing them back as well as testing transistors and looking for blown caps and a smell test but nothing came up. Hit the power button and surprise all speakers worked perfect.

The only solution I came up with was either the heat from the previous night of running made it work (though I doubt this as it was unplugged all night and it ran perfect while dead cold) or the fuses I pulled to test for the channels might have had oxidation between the clips and by moving it to test the connection was re-established (this is what I think was the accidental fix).

Oh well, no longer looking for a new receiver so happy I am.

My 875 currently developing crackling sounds on both left frond and right surround back, after 5 yrs working without any issues.
Cables and speakers are checked and confirmed not the cause.

Anybody encountered this before and what is the possible cause?
post #6042 of 6042
My HDMI port either 1 or 4 worked the other day. My x-box one had video but no audio. I swapped cable around then determined that it was not cables, but the port itself. It lets audio but not sound through. when I used both cables I was testing they worked in the other port. Any suggestions?
