You know that from the filter parameters such as topology (Linkwitz-Riley, Butterworth, Bessel, Chebyshev, etc.), order (roll-off), and target corner frequency. It is a transfer function so is always "proper" but no filter instantly changes from 0 dB to whatever dB per octave -- there is always a transition region. The idea is that, in a crossover, the high-pass and low-pass sections with the same corner frequency maintain the same acoustic output through the crossover region. Both sides roll off "together" so the output is constant. Sometimes the crossovers can get rather complicated but for most of us just a simple LR4 (Linkwitz-Riley, fourth-order, 24 dB/octave) will be good enough. For example, look at the diagram here: en.wikipedia.org/wiki/Linkwitz%E2%80%93Riley_filterHTH - Don I just think it is a dangerous business planning to use a Surround Sound Processor as your speaker driver crossover in multi-amping. If a setting gets accidentally changed or if it resets on a firmware update or you accidentally engage a profile like Dirac where the crossover filters you've made are suddenly lost then you can blow your tweeters in an instant if they get the wrong and full range signal. If you do not know what you are doing, sure. And even if you do mistakes can be I(and have been) made. But some of us have been actively bi-amping speakers for decades (for me, since the mid-1970's) so might be able to handle it. And some surround processors do a good job of it, e.g. Trinnov. But that is not really what I was thinking. Providing a full-range signal to both outputs means you gain nothing in (voltage) headroom for the amplifiers. Even though bass power is nil in the treble amp, and treble power nil in the bass amp, the voltage applied to each is exactly the same. That is the thing that bugs me about so-called "passive" bi-amping in AVRs. (Until recently, passive bi-amping to me meant a passive RLC line-level crossover vs. an active line-level crossover using tubes or transistors.) Most of the power is usually in the bass, and if you believe equal-loudness curves, power can be 10x to 100x higher in the bass than in the midrange. To use a very simple hand-waving example, let's say the output is equal and we have a signal that has 1 V at 1 kHz and 1 V at 50 Hz. Assuming they are independent, the peak voltage from the RMC-1 (or anything) will be 2 V for the combined signals. Now let's say the voltage gain of the amps is 20 dB, a factor of ten in voltage. The bass and treble amplifiers must each deliver 20 V to the speaker; 20 V to the low section, and 20 V to the high section. The crossover inside the speaker will separe highs from lows and reject the out-of-band energy, so the woofer sees only 10 V and the tweeter only 10 V, but still both amplifiers had the same input and thus same output. And bear in mind the ratio may be much worse in real life, with the bass having much higher power than the treble. Now consider implementing a crossover in the AVP. Assume I have no idea what I'm doing, but I know from the speaker's manual that the woofer crosses over at 150 Hz, the treble section (probably mid-range and tweeter) handles everything above that. I'll let the passive crossover inside the speaker do its thing and set the AVP crossover to 300 Hz, an octave above, so it doesn't significantly affect the speaker's roll-off. (That depends on other things but this is just an example.) Now, only 1 V is sent to the bass amp, because there is no treble signal, and 1 V to the treble amp, because there is no bass signal. I've gained 6 dB in headroom, a factor of two in voltage and four in power, in each amplifier by not sending it out-of-band signals. Alternatively, I can use a bigger amp for bass and smaller for treble, now that I have "blocked" unused signals before the amps. Without that internal AVP crossover, each amp has to deliver the same voltage (though not the same power) to the speaker, so essentially you need to have the treble amp match the bass amp even though typically only a fraction of the power is needed from the treble amp.

Checked the cables multiple times, but thanks for the suggestion. 👍I don't have the equipment or the skills to make my own cable 😊But I think I will look for a mini jack to micro jack cable in stereo or mono depending on what geebo comes back with. is a cable that I use and it works great. No need for finicky adapters that are prone to loosing contact...  They don't ship to Denmark :-( It's actually not easy to find this type of cable here in Denmark, I found it with the right connections but it was stereo. I will try searching a little more or else I know a guy that should be able to make me one :-) Thanks guys for all the help. 👍 |

Back and after 4 1/2 hours of the RMC not being on, it appears to be working with 1.7/6 firmware. (No, I did not take a 4 1/2 hour nap!) I just now installed 1.10 and this time I unplugged the RMC's power and removed all of the source devices for about 30 seconds. I then plugged power and sources devices back and using the rocker switch powered the RMC back on. After going through its reboot, the RMC came up on the correct input (Cable TV) and the audio is working through the RMC!! I will not know for sure if the issue has been resolved until the RMC has been put into Standby mode for several hours. So I will be going into Video Remains on mode now. If anyone has issues after updating, I strongly suggest that they do as Keith suggested and I should have in the beginning the following: 3) IF YOU ENCOUNTER ANY ODD BEHAVIOR AFTER PERFORMING THE UPDATE... WE SUGGEST THAT YOU RESET ALL OF THE HDMI DEVICES YOU HAVE CONNECTED TO YOUR PROCESSOR. TO DO THIS YOU MUST PHYSICALLY UNPLUG THE AC POWER ON YOUR PROCESSOR, YOUR TV OR PROJECTOR, AND ALL CONNECTED HDMI DEVICES. Everything must be unplugged AT THE SAME TIME for at least ten seconds. This will ensure that all of your devices go through a full reboot. (We DO NOT REQUIRE this but, if you have ANY problems, then you should do it.) Will let all know how it goes latter on tonight. Before I leave this issue, just want to say that the performance of the RMC with this firmware is outstanding! Bring on Dirac!! Regards, Steve So far so good. Everything working as it should. Big test will be in the morning but I have a feeling it will be fine. Tks to all, Steve Well it did not work. Video Remains On mode is working as it should. However, when I turned on the RMC to get the audio through my speakers (not the sound bar or tv's speakers) there was no audio. Once again I could get audio from watching a program on my ATV4K but not the Cable Box. I tried turning the Cable Box and TV off and then back on again but no luck. Once I changed the Standby mode in the RMC to Lowest Power and rebooted, the audio from the Cable Box would come through the RMC. It seems that the only way I can get audio from the Cable Box/TV is to reboot at Lowest Power. The RMC can be turned off for short periods of time and still work with the audio from the cable box. But overnight appears to be too long. My cable box is a Fios TV One and tv is a Sony 65Z9D. No settings have or were changed from when this function was working to when it stopped working. The only changes have been firmware updates. The incoming cable signal goes to the TV One cable box and from there to the RMC HDMI1 input. I also have the tv connected to a sound bar via an optical cable. With this setup, when things are working as they should, I get audio through the sound bar and the RMC at the same time. I therefore have to turn the sound bar volume down to listen to the RMC. Otherwise, there is a slight echo effect since the 2 outputs are not exactly in sync. This last bit provided just for full disclosure. Don't believe it has any effect on what is going on. So I don't take up a lot of space on the board, I am not going to post anymore unless I come up with some sort of info that could shed some light on what is going on. Once again I am going to go back to firmware 1.7/6 (which worked) and then each evening before turning off the tv for the night I am going to load a different firmware. I have 1.8, 1.9, 1.9/9 and of course 1.10. Will see if I can find where this stops working for me. Take care, Steve |

I'll mirror what others are saying. I've sent this in email to the Emotiva team, but I feel the need to say it here as well. I know I can be overly critical at times about certain things, and have had my fair share of rants, but this new firmware is stellar. I applaud the effort the whole team contributed to rewriting and delivering a solid update with many fixes. Outstanding job Emotiva! Thank you very much! I will pass this onto the team. Lonnie |

There are many really good things about the new firmware.
Unfortunately one thing that is still problematic is a loud burst of noise with DSD over HDMI from an Oppo 205. When the stereo SACD disc finished playing and therefore DSD was switched back to PCM from the player, I was rudely shocked by a loud noise out of all speakers.

Lonnie Hi Lonnie, Just a bit more info. One thing I want to point out is that when I am not getting audio from the RMC, if I select the Info button on the RMC remote, it brings up info that appears to me to show that a signal is being received but for some reason is not getting to the amp and connected speakers. The signal is being sent to the tv from the RMC because I am getting a Video and Audio signal on/from the tv. I hope this makes some kind of sense. Appreciate the help, |

If the audio from the Fios box is set to Dolby, please try changing to PCM. I've had issues with Dolby on my TiVo while in Video Remains On (and other devices while the XMC-2 is on), but as soon as it's changed to PCM the problems go away, and the same is true for other devices.

Couple things, take a look at this link forums.verizon.com/t5/Fios-TV-Technical-Assistance/FIOS-TV-One-VMS4100-A-V-Sync-Issues/td-p/877379 and see if this seems like it has some similar issues going on. It also states how to get to the menu area for audio settings. Are you getting the audio from the box via a non-HDMI method, like Optical? If so, then try HDMI only. |

You know that from the filter parameters such as topology (Linkwitz-Riley, Butterworth, Bessel, Chebyshev, etc.), order (roll-off), and target corner frequency. It is a transfer function so is always "proper" but no filter instantly changes from 0 dB to whatever dB per octave -- there is always a transition region. The idea is that, in a crossover, the high-pass and low-pass sections with the same corner frequency maintain the same acoustic output through the crossover region. Both sides roll off "together" so the output is constant. Sometimes the crossovers can get rather complicated but for most of us just a simple LR4 (Linkwitz-Riley, fourth-order, 24 dB/octave) will be good enough. For example, look at the diagram here: en.wikipedia.org/wiki/Linkwitz%E2%80%93Riley_filterHTH - Don I just think it is a dangerous business planning to use a Surround Sound Processor as your speaker driver crossover in multi-amping. If a setting gets accidentally changed or if it resets on a firmware update or you accidentally engage a profile like Dirac where the crossover filters you've made are suddenly lost then you can blow your tweeters in an instant if they get the wrong and full range signal. Agreed, it is dangerous if you rip out the crossovers. However, I will still be passive bi-amping the Salon2’s. Limiting the range still will reduce the voltage amplification to my AHB2 amplifiers. These amps have extensive and accurate clipping indicators and when I push the the clip lights indicate voltage clipping and not current clipping. That said, I want to do this because it’s fun  - Rich |

Tried 1.10.
Switching inputs is quicker BUT the RMC does not switch on any more along with my TV. This is a must have convenience feature that I require. (Yes, I tried unplugging everything from power after the update.)
Went back to 1.9 and that worked again.
So it goes. Have to stick to 1.9 for now I suppose.

If a setting gets accidentally changed or if it resets on a firmware update or you accidentally engage a profile like Dirac where the crossover filters you've made are suddenly lost then you can blow your tweeters in an instant if they get the wrong and full range signal. If you do not know what you are doing, sure. And even if you do mistakes can be I(and have been) made. But some of us have been actively bi-amping speakers for decades (for me, since the mid-1970's) so might be able to handle it. And some surround processors do a good job of it, e.g. Trinnov. But that is not really what I was thinking. Providing a full-range signal to both outputs means you gain nothing in (voltage) headroom for the amplifiers. Even though bass power is nil in the treble amp, and treble power nil in the bass amp, the voltage applied to each is exactly the same. That is the thing that bugs me about so-called "passive" bi-amping in AVRs. (Until recently, passive bi-amping to me meant a passive RLC line-level crossover vs. an active line-level crossover using tubes or transistors.) Most of the power is usually in the bass, and if you believe equal-loudness curves, power can be 10x to 100x higher in the bass than in the midrange. To use a very simple hand-waving example, let's say the output is equal and we have a signal that has 1 V at 1 kHz and 1 V at 50 Hz. Assuming they are independent, the peak voltage from the RMC-1 (or anything) will be 2 V for the combined signals. Now let's say the voltage gain of the amps is 20 dB, a factor of ten in voltage. The bass and treble amplifiers must each deliver 20 V to the speaker; 20 V to the low section, and 20 V to the high section. The crossover inside the speaker will separe highs from lows and reject the out-of-band energy, so the woofer sees only 10 V and the tweeter only 10 V, but still both amplifiers had the same input and thus same output. And bear in mind the ratio may be much worse in real life, with the bass having much higher power than the treble. Now consider implementing a crossover in the AVP. Assume I have no idea what I'm doing, but I know from the speaker's manual that the woofer crosses over at 150 Hz, the treble section (probably mid-range and tweeter) handles everything above that. I'll let the passive crossover inside the speaker do its thing and set the AVP crossover to 300 Hz, an octave above, so it doesn't significantly affect the speaker's roll-off. (That depends on other things but this is just an example.) Now, only 1 V is sent to the bass amp, because there is no treble signal, and 1 V to the treble amp, because there is no bass signal. I've gained 6 dB in headroom, a factor of two in voltage and four in power, in each amplifier by not sending it out-of-band signals. Alternatively, I can use a bigger amp for bass and smaller for treble, now that I have "blocked" unused signals before the amps. Without that internal AVP crossover, each amp has to deliver the same voltage (though not the same power) to the speaker, so essentially you need to have the treble amp match the bass amp even though typically only a fraction of the power is needed from the treble amp. HTH - Don Well said! Trims allow mixing different amps (horizontal bi-amp) which is also not dangerous. - Rich |

Tried 1.10. Switching inputs is quicker BUT the RMC does not switch on any more along with my TV. This is a must have convenience feature that I require. (Yes, I tried unplugging everything from power after the update.) Went back to 1.9 and that worked again. So it goes. Have to stick to 1.9 for now I suppose. Re-try 1.10 and in the menu select HDMI CEC and make sure that it is set to on. This should fix things. |

CEC was on before the update, and I re-checked if it still was after the update, and it was. So that's not the issue. BTW... on 1.10 it turned off along with the TV, also volume control worked via TV remote, just switching on scenario did not work. |

Best I can make out from the Fios TV One menu under Audio Format is a selection between Surround, Stereo, and Mono. Currently set for Surround but will change to Mono and see what that does. Could not find a menu selection that would let me choose PCM or Dolby.. Will take a while to see what effect this has. Could take at least until this afternoon so do not be surprised if I don't have an answer right away. Thanks for the help. Couple things, take a look at this link forums.verizon.com/t5/Fios-TV-Technical-Assistance/FIOS-TV-One-VMS4100-A-V-Sync-Issues/td-p/877379 and see if this seems like it has some similar issues going on. It also states how to get to the menu area for audio settings. Are you getting the audio from the box via a non-HDMI method, like Optical? If so, then try HDMI only. Thanks much for the link. Will give it a look. The audio signal (and video) are being sent to the tv from/through the RMC. When the RMC is in Standby (Video Remains On), the video and audio are gong to the tv as they should. When I turn the RMC on, the video and audio are still going to the tv so I can therefore hear the audio through the soundbar connected to the tv via an optical cable. However, I can no longer hear the audio being played through the signal going from the RMC to my amp. I use to be able to do this on firmware prior to 1.9. I now have 1.8 loaded and hopefully will be able to tell later if this is good or not. The problem with my testing various things is that it can take several hours or more with the RMC off for the issue to come up. It sometimes take overnight for the issue to come up. Thanks for the help, Steve |
