DIP switches interfering with each other?

DIP switches interfering with each other?

Have any one seen that the DIP switches on the back of the monitor interfering with each other?

What I've noticed is that when I set one monitor to playback AES Channel B using the DIP switch, its woofer will be muted as well, but if set to playback Channel A then the woofer works. In both situations the woofer mute switch is set to off and the AES Channel selection is taking effect correctly.

Since the woofer mute switch is right next to Channel B, I'm wondering could there be any interference between them?

btw. If I use GLM instead to select AES channel then channel B does not mute the woofer. This (DIP switch interfering) also does not happen on the other monitor.

Hello,

Thank you for your message. Can you please state the monitor model and serial number?

How about if you turn the woofer mute dip on, does the AES/EBU channel change then?

The model is 8260APM.

It's hard to dig out the SN but GLM reads:
Unique ID 73411
Bar Code H75074H029
from the speaker.

You are right, the channel changes with woofer mute as well, tried 4 combinations of 3 switches (ch a, ch b and mute woofer) and swiping signal on channel b only, I'll table them:

CH A, CH B, Mute Woofer, Behavior
off, on, off, the signal is played but only the upper part (over 400hz)
off, off, off, the signal is played in full range (meaning 20-400hz are also played)
on, off, off, nothing is played
on, off, on, the signal is played but only the upper part (over 400hz)

I think the last situation means the channel does change with woofer mute, because in this case since a is on and b is off, the signal on b should not have been played, but because woofer mute is on, b is also 'on' and thus the summed a+b is played with woofer mute effect.

So it does seem that these 2 switches (ch B and woofer mute) are shorted so one can pull the other down (or up?)?

Correct. If you want this to be fixed, the speaker needs to be serviced.

Thanks for the quick conclusion.

It is quite a disappointment to find such a "simple" defect on a otherwise very fine speaker. Since the issue is there from the moment I bought it as a brand new unit. I guess the service should be under warranty?
