Guidelines and operation of this device
The connection panels on the Artis 10 MKII, 12 MKII and 15 MKII are almost identical.

The following information applies to these
connectors:
- The speakers have an impedance of 8
ohms. Always choose an amplifier that can
provide at least the full RMS capacity of the
speaker with this impedance to ensure a
good balance between the two. The more
powerful the amplifier, the less hard it
needs to work to deliver the power. Be
aware that with a high-power amplifier
however, it's also easier to provide a
speaker with too much power. Always listen
carefully to the speaker and reduce the
volume if there is any distortion or crackles
in the sound.
- The lockable speaker connectors need to be turned by 90 degrees upon insertion in order to create a
secure connection. You'll hear a 'click' when they're connected properly. They can only be unlocked by
pulling the tab towards you and then turning them by 90 degrees in the opposite direction. This functionality
ensures a secure connection when the speakers are being used.
- Bear in mind that the impedance of a connection is halved if a speaker is connected in parallel. For
example: by connecting two 8 ohm speakers, the joint impedance will be 4 ohms. The capacity is the sum of
the two speakers together and will be divided equally so long as the speakers are the same.
Most PA amplifiers can handle a load of 4 ohms per channel, so it's usually possible to connect 2 speakers in
parallel to a PA amplifier. Always consult you amplifier's manual beforehand however, to find out its limits and
make sure that it can handle this type of setup.
- The speaker connector terminals are always wired to +1/-1 which is standard for most speakers and
amplifiers.
The information in this user manual is subject to change at any time without notice.
