Hey guys, if you are running a 7.1 setup, what do you have your settings at to make the rears work even if it is only a 5.1 signal? essentially i want all 4 rears working even if it is only a 5.1 signal.

What do i leave, what do i change etc.

Thanks!

Push the audio button twice and scroll to pliix movie. You can also go through the menu and change default to pliix movie for 5.1 sources.

Hi

I've set up an MRX 300 for the first time and wondering whether anyone has any advice on settings, speaker placement etc. In particular I note that the fronts appear to have a large spike below around 100Hz. I was also surprised that the MRX has classified my fronts as small.

I’m using the MRX 300 as a pre-amp to an Arcam A18 driving a pair of Spendor BC1 floorstanders. Centre speaker (Spendor C3) and surrounds (Monitor Audio Radius 45) are driven by the MRX 300. Sub is a BK XLS200 MK1.

Level calibration as follows:
Dolby volume off
DVCO 0
Front left +3dB
Center +1dB
Front right +1dB
Surround right -1dB
Surround left -2dB
Movie sub -2dB
Music sub -2dB

Movie/Music config:
Front small 100Hz
Center small 60Hz
Surround Small 120Hz
Aux None
Sub On

Thanks in advance for any help!

Those Spendors have FR of around 55hz, so yes small is correct. I wouldn't set them any lower than 60hz.

The center wouldn't set lower than 70hz.

Thanks. If I change the crossover do I need to run ARC again? I presume not.

Any other feedback or suggestions?

The reason ARC set your main xover to 100hz
Is that you have a lot of boundary gain/reinforcement.

I would NOT lower the xover.

You need to work on the placement of your L/R speakers.
Try to pull them out from the walls and/or get them
Away from corners. Then redo the ARC program.

If you set yours up as follows in the Listening Mode Presets menu you'll use all four surrounds (except DD-EX and DTS-ES will use 3 or 4 surrounds depending on the mix).

It's very important that you set 5.1 DTS to Last Used and DTS-ES to None. If you have 5.1 DTS set as Last Used and DTS:ES set to Same as DTS 5.1 , your DTS-MSTR 7.1 movies will default to 5.1 and and you'll have to use the audio button to set them to 7.1 for every movie and turning off the receiver will reset to 5.1 for DTS-MSTR 7.1.

2.0 Dolby Digital Surround - PLIIx Movie
Muilti Channel PCM - PLIIx Movie
5.1 Dolby Digital - PLIIx Movie
Dolby Digital Surround EX - None
5.1 DTS - Last Used
DTS-ES- None

Thanks grasshoppers. I will have a play with the L/R placement and remeasure.
