Hi all!
Sorry if this question has an obvious answer :)
I plugged stereo speakers in the jack plug at the back of the monitor of my NeXTcube (leftmost connector, with the "headphone" logo). But, any sound is still played by the monitor speakers. Is there something to set somewhere?
Thanks!

Hi
@tygre , as far as I remember I had my Hifi-system connected to the Megapixel monitor, but I am not sure any more. Anyhow I found this in my Usenet archives, possibly giving some hints...
External speakers may need amplifier:

I'm trying to hook stereo speakers up to my NeXT. I got a pair of
radio shack speakers, and speaker wire with RCA-standard plug.
I ran it into the line-outs on the back of the Megapixel, and hooked
the other end to the speakers. I get only very faint sound in the speakers,
even at max volume. Is there something else I need---an amplifier or
some way to switch the sound out to the line outs?
(The speakers are small, 15 watt with 8 ohm impedance.)
Any help is appreciated.

Simplest remedy is an amplifier. Doesn't have to be very
powerful. I put the line outs from the MegaPixel into the
aux inputs of my boom box, and it works fine.
A hint that you should disable the internal speakers:

Does anyone know how to disable the monitor's speaker? Whenever we plug
in a pair of headphones for private listening, the speaker doesn't turn
off. Any suggestions/explanations?

Hit "mute" <Command> & the small speaker key. This stops output on
the monitor's speaker but still lets you control headphone volume from
keyboard.
And a warning of magnetic disturbance:

What has occurred is that you have inadvertently induced a persistent
magnetic field in the picture tube. This can happen when a constant
(non-randomized) magnetic field induces a magnetic moment in material which
is susceptible to the retention of a magnetic field (i.e., you've magnetized
it).
This can be reversed by applying a strong randomized magnetic field to the
tube: Degauss it! If the automatic degaussing circuit in your Megapixel is no
longer functioning (or is not strong enough to randomize the induced magnetic
field), you can use a TV degaussing coil.
If you choose the latter, here's how to do it without damaging your equipment
(some parts of your equipment MUST NOT be demagnetized):
1. Unplug the Megapixel display.
2. Remove your cube / slab from the room.
3. Plug in (or switch on) the degaussing coil at least 10 feet away
from, and in front of, the FACE of the Megapixel tube.
4. While you slowly rotate the degaussing coil (making a vertical circle),
slowly move closer and closer to the face of the tube.
5. When you are about 2 or 3 inches from the face of the tube, reverse
step 4 by walking away from the tube, still rotating the coil.
6. When about 10 feet away, turn off / unplug the coil.
7. Reconnect your system -- it should be cured. If the effects are
still there, only less so, repeat the procedure, taking more time
in step 5.

Hi Nuss and thank you!
Muting the sound using Command + Small Speaker, I muted the monitor and then speakers took over :)
Cheers!
