    Smiler problem,however I have a buzz (low and in the background) on all media,volume up and buzz stays at the same level,vol off and buzz goes!



    Philips claim they have never heard of it,however many blogs online.



    Philips think it is mains hum and was advised to try another socket and if no joy try an other house.



    I did and no joy,philips advised it would be 200 euros to have a look at it.



    This is where I am at the moment.



    Any suggestions?



    PS the WAC 700 has been as good as gold for the two years I have had it,this problem has just occurred,this is my only problem with this device.

SOURCE: Denon AVR-810 going into PROTECTION mode

It sounds like there is a problem with the differential circuit. The bias I am not sure about, as every unit is different. You should get the service manual to be sure or call Denon and see if they can give you an idea. Good Luck

4. Your volume settings are too low or muted. Increase your volume by pressing the + key located on top of the right satellite. You can also check your volume through the volume control located in the taskbar. To mute and unmute the speakers, press the + and - controls at the same time.

SOURCE: On screen display menu

I scratched my head over this for an hour. The manual says you can access the OSD from the unit, but I see no way to do this. From the remote, you have to select the "AMP" setting at the top of the input list. Then hit the OSD button. Assuming your monitor is set up correctly, this will bring up the On Screen Display. Then hit the "Menu" button also on the remote, and you can make your adjustments. Good luck!

SOURCE: Center Speaker Audio Very Distorted

Love your screen name.

You didn't say what, if anything, preceded the appearance of the problem. There might be a clue.

Can you describe the distortion? Is it excessively bassy? If so, is it happening on all sources?

I'm assuming this is a modern digital receiver that is capable of many soundfield simulations as well as native Dolby Digital, DTS, multi-channel. If so we can use a stereo source and through simulation redirect some of it to the center speaker.

Using one of your receiver's many multi-channel simulation modes, put in a CD or tune an FM station and use it to diagnose the problem during later steps.

If it's only a single source and that source uses individual analog channel RCA cables, swap in another one or temporarily move the Center Channel feed to one of the other channels to see if it's before the receiver (in the source).or inside the receiver.

For multiple sources:

Is your Center speaker defined properly as Large or Small in the receiver's setup menu?The size refers mostly to the bass-handling capacities of all your speakers rather than their physical size. Speakers designated as 'Small' will not be sent much in the way of bass because they can't handle it well. The LFE/subwoofer channel(s) will get all the bass that was intended for them instead.

If you have a Small speaker improperly defined as Large it may be getting bass that it can't handle and that might sound like distortion. Having a Large speaker defiend as Small would result in less bass than expected but otherwise 'clean' sound.

Check the speaker setup in the menu for excessive volume level relative to the others. There is usually a calibration procedure the receiver will use to help you adjust the subjective voume of each speaker using white noise or tones.

Hope this helps.

Phillips wac700 says booting up has not been used for a while


Hello
Just unplug the device from AC mains socket and replug it after 3 minutes and see whether it helps you. If not, a firware upgrade will be necessary. The supplied PC installer CD contains Media Manager [DMM] software. it will help you to upgrade for WAC700 center. For details see DMMs' help file. Refer to the manual CONNECT YOUR PC to learn how to install the software. OK.

I have wac700, cd stacked in cd driver. How can i remove side speakers and open the device?


1. Unplug the two audio connectors from the base of the main unit and free the external speaker cables.
2. Press in each of the bottom clips towards the centre of the main unit and lift the speakers up and out of their mounting key-holes.
3. Remove the six recessed T10 screws holding the back of the unit on.
4. Unplug the two ribbon cables between the main unit and front panel.


The CD mechanism should now be accessible and it any trapped CDs can be removed.

Hi with regards to my audio a7x monitor speaker... on the unit it says 2 options 220-240V 50hz 100-120V 60hz IT says use only with a 250v plug.. which i did:/ the speaker just doesnt turn on at all?...


You must switch the voltage option to match the mains voltage in your area.
If you have 220 or 240 AC volts mains voltage in your area and you have set the switch on your monitor speaker to 100-120 volts and then connect it to the mains supply then you have destroyed your speaker.

How can I detach the speakers from my philips wac700


Lay your unit face down on something soft like a towel maybe.
Remove the stand, which had a small tongue that you'll need to depress.
Hold the centre segment firmly at the top and then with the heel of your hand, give the base of whichever speaker a few firm thumps upward. (This takes quite a bit of force!)
The speaker are attached via 'mushroom' pegs into a rubber-lined hole which opens to a slot, so you're trying to push them upward until the pegs are in the hole instead of the slot and they will then just pull out.
WARNING: There is not a great deal of play in the speaker connector wiring so be careful once the speaker is free!

Got new laptop with vista. Can t install wacs700 software.


Hi !

I strongly suggest that you discuss WACS related issues in theStreamium Café (www.streamiumcafe.com). This is where you will find ananswer to your problem (look for the WACHandler" threads where you willfind a link to my application ;)
You can also try the WADM application from Philips. It is made for the newer WACS units but it works with the WAC700 also.

Cheers !
