or are you saying we need to determine the preamp setting is correctly activated before solving this issue?

Hi Ralf,

I have a similar setup with yours and I am thinking to moved to Pioneer LX73 amp. For the past few years, have you encounter problem using 12v trigger from the amp directly to keep the beolabs on?

The thread for my situation just in case

/forum/general-discussion-and-questions/crackling-noise-from-bampo-speaker-with-non-bampo-amp

Many thanks for your input.

Thanks for you reply. I actually jump the boat and got my LX83 and all hooked up fine, would eventually like to move to Beosystem 4 if not for its price. :)

Great detail on your setup - love the pictures and the SIMPLE explanations of how/why you setup your system!

My current setup is a Marantz AVR, pair of BL8000 for FL/FR, Penta MkIII for RL/RR, Velodyn SW, and a single BL4000 as a center channel speaker.   I have another BL4000 that I'd like to pair with the center channel to have two BL4000 center channel speakers.  

How did you link the two BL4000?  Did you daisy chain with a powerlink cable or did you use a splitter via the RCA cable to the two speakers?  

Also, any thoughts on the best way to mount the speakers?  I'd like to mount them horizontally underneath the TV (approx 3 feet off the ground).  Should they be angled (i.e. slightly upward) so that the speaker faces straight out?  If feels like this setup forces sound to go down.  

The next step is figuring out the trigger output.  Currently using pretty ordinary shielded RCA cables.  It looks like using the trigger output would entail buying to cables.  May be a good excuse to upgrade!

Can this thread be pinned?

I was thinking of suggesting if we can pin a few threads to assist new users to the Forum.

Things like where people ask the same questions such as:

- how do i use an Amp from another brand with Beolabs

- how do i use Beolabs with a TV from another brand 

- how do i use a record player with Beolabs 

etc 

I've been using a Marantz amp for years with Beolabs.  have some passive speakers mixed in as well as I have a 9.2 setup with ceiling speakers, etc. .  No issues at all.  There's the initial click when they first come on but a proper surround movie you will never see the surrounds go off and on at least in my experience.  Plus the non-B&O setup gives you the flexibility to use the passive speakers.  Never had a need to use triggers.  

Hi everyone,

Superb thread, sorry I missed this previously.  The following summary may help:-

• All Beolab speakers can be used with a non-B&O AV system, although Beolab 2000 and 3500 should be avoided as these don't behave well as part of a surround sound setup.
• Beolabs 2, 7-1, 7-2, 7-4, 7-6, 10 and 2500 don't have Line input modes, so these will need a trigger signal to activate them when used with a non-B&O AV system.  Other Beolab speakers not mentioned below can optionally use these trigger cables, but they aren't essential.
• Beolabs 5, 2000 and 3500 need a B&O remote control to activate them when used with a non-B&O system
• Beolabs 50 and 90 require the B&O app to set them to Line mode when used with a non-B&O system

All other Beolab speakers can be used in Line mode with an AV receiver that has RCA pre-out sockets fitted.  (They can also be used with the speaker terminals of a receiver or amplifier via an extra converter box).  Don't connect Beolab speakers directly to the speaker terminals of a receiver, as this will cause damage to the speakers.

Speakers with Line input modes can be set to trigger on and off automatically when the music plays - we find that in over 90% of setups this works well.  In a few cases where users tend to listen at lower volume levels, the speakers can turn off from time to time when in use, so in these cases it can be helpful to use trigger signals to manually activate these speakers while the receive is powered on.

The USB output of a TV should not be connected to Beolab speakers, as most TVs have electrically noisy voltage rails, which can cause unwanted noises through the speakers.  The 12v trigger on an AV receiver should also not be connected directly to Beolab speakers (several receiver manufacturers have told us that doing this could damage the receiver and would void their warranty).  for this reason, I don't offer cables that use the 12v trigger on the receiver.....if you decide to use these, please check with the seller to ensure that the 12v trigger is electrically isolated from the audio connections of the speaker to avoid any risk.

The safest option where a trigger signal is needed is to provide this via a mains power adapter, you can then either control this manually or use a remote control to power this on and off when required.

I am always happy to help with any enquiries, as we are setting up systems like this on a daily basis.  Please feel free to get in touch via my sponsor link below if you have any questions about using Beolab speakers in a non-B&O AV system and I can help you to get the best results.

Kind regards, Steve.
