No la, we not bashing trinnov. Just stating that an experienced calibrator makes a difference. So even on the same room correction software, calibrator A vs calibrator B can make the same hardware sound very different with one sounding superior over the other .
There is one guy on the Facebook anthem page that does remote calibration services and there were tons of feedback that he is excellent
I just pull out 3 samples…all from different users who have engaged Yves calibration services. I’m not sure what he did there but all are reposting that after engaging his help, the system benefited greatly from his tweaks , vs running the auto ARC process
Yes I knew this chap, myself and him were involved in some of the very first tutorials that we separately dished out about a yr ago. Unfortunately, I kena kicked out from this Anthem Lover’s Group FB because some of my comments were taken out of context and one of the Mods in that group was not happy with the way I retorted in his post. Long story short…this is a very good resource page for Anthem users but make sure not to rile up some of the Mods there. There is another Mod that is very helpful, knowledgeable and humble…forget his moniker. He is an Anthem dealer. He reminds me of Alfie who share useful knowledge of the product he sells.
Hint: Yves and Home Theatre Guru (yes the bald guy from YT) are not seeing to eye to eye simply because this Home Theatre Guru guy do not believe in modifying a .arc file and then charging people money for the remote service without even going down to the client’s place. Hence, indirectly alluding that Yves is not legit. Personally I think Yves has his own ways when it comes to modifying other member’s .arc file.
Ya there is one guy I think Cory. Not bad, he is quite good too. They know the product inside out. I mean as a consumer, I wouldn’t mind buying from someone knowledgeable and who knows their product inside out. Some sellers just sell and say bye bye… no benefits buying, all they are interested is selling and making a profit… but some sellers are different, they go all out make sure you fully benefit from the products they sell u
Another dealer who is good is Sky Audio, he is very knowledgeable on hifi stuff and he goes all out to help customers to maximise the potential on their system…
I don’t normally comment on the Anthem FB page, so I just sit back and relax and observe……
Hi everyone, I wanted to ask all of you if there is a sound difference between the Mrx 540 and the Mrx 740 for 5 channel movie watching. I am looking to add 7 channel amp later on. Please give your experience with either. Many thanks.
Audio wise, the sound signature should be no difference since all using the same DAC. But if you can spend a little more, go for 740 which will provide more juice to your bed layer channel (5 channels in your case) since 540 has 100w per channel. Furthermore, if you plan to go for more speakers next time, 740 provides up to 11 channel pre outs as compared to 7 channels. If you want indeodent subwoofer preout, then go for the higher end model, 1140 for the best of everything.
I am very perplexed in the management of the 2 subs during the arc. In the old model the 2 subs were calibrated together and this allowed me to obtain (through the internal equalization of the SVS subs) a very linear response:
Now in 70 the management is separate and I don’t understand how this takes into consideration the fact that the sound waves emitted by the two subs can cancel or increase.
I tried to equalize each sub separately and then launch the arc but the final result doesn’t have the same punch as the old calibration.
If I use the old EQs (which fortunately are in the subs’ memory) I get graphs further away from the reference but which sound better … the only explanation is that the subs are calibrated to play together.
What do you think about this issue? What is the best way to operate? Why did they switch to a separate sub management and why they doesn’t allow the choice to manage them together as one?
Thanks for the help
Ps: when I try to run the auto phase detector for the subs I get a normal sweep from the front left speakers and a barely perceptible sweep from the sub…is that the way it should work or is there a bug in the procedure?
I am only going to focus on this part of your comments. First and foremost, the previous model (AVM 60) you’ve owned sports 2 pre-outs for LFE channels but they are working in parallel, meaning the sum of the outputs for 2 subwoofers will be combined into one. This explains why in the past, you get a summation of the total output for your subwoofers. AVM 70, on the other hand, comes with 2 independent subwoofer pre-outs that can be measured individually relative to the Main Listening Position (MLP), this is why there is an auto-phase correction feature added to calculate the delay in acoustical distance in the new ARC s/w (from ver 1.6.5 onwards). If you are not using ver 1.6.10, pls do so immediately as this is by far the most stable version and do not let other people tell you otherwise.
To answer your question on why don’t Anthem come up with the feature of combining all the subwoofers into one single array, this is something most of the Anthem fans have been clamoring for all these while since the launch of the Gen-4 MRX and Pre-amps. While it will be good to have this feature, it is NOT the reason why you are unable to get good-quality bass out of your system.
Remember, ARC calibration is different from Audyssey, it is measuring each speaker and subwoofer by taking into account the room acoustics (room modes) you have. Each user has a different room mode which makes it harder to dispense a “one-size-fits-all” solution to every Anthem user. Each room is unique. For starters, I would advise against using any SubEQ on your subwoofers and disabling that. Run ARC as it should be then take a look at the final target curve (black line) and compare it to the pre-measurement curve (red line) if the “shape” for both is pretty close to the one depicted in the post, then you are good. Only enabled/run SubEQ on your subwoofers when the pre-measurement (red line) deviates too much from the SubEQ you’ve used for your subwoofers. If you are not satisfied with the current bass, I suggest you re-do the ARC and if the result is still the same, then you can play with the advanced settings like subwoofer high pass order (flat, 1st order all the way up to 4th order max) and high pass frequency (if you are very certain that your subwoofer supposed to churn out more output in the modal frequency say 20Hz and below but the in-room response curve is showing you a different result, then the best solution is to reposition your subwoofers since ARC probably has determined a null at your MLP which cannot be fixed by room correction at this stage due to your room mode.
Yes, it is normal, remember the wavelength of bass is longer and omni-directional compared to the ones emitted from your normal speaker driver. This is why you cannot rely on your ear alone to determine the overall Sound Pressure Level (SPL) of the speakers and subwoofer output when test tones are played.
Based on the compatibility chart from Anthem website, the gen 3 models can use the latest ARC ver 1.6.10 but I don’t think the more advanced features like auto phase control can be used. Basic calibration measurement should still work.
New beta Anthem Room Correction (ARC) is/w is available for download but you can choose to skip this one as it is targeted at the new Paradigm subwoofers XR-11 and XR-13.
