Cooling; Quick Start - Dynacord D 11A Mode D'emploi

DYNACORD

2.3 Cooling

This is a powered speaker with a very high efficient amp-
lifier module and as a result does not get really hot. The
temperature of the amplifier module is monitored. In the
rare event it does get too hot it will automatically shut
down to protect itself. Once its temperature has returned
to within its operating range the amp will turn back on.

2.4 Quick Start

CAUTION: After installing the system, first switch on the mixing console and position the mixer's master faders to
their minimum settings. That followed, switch on the D 11A and use the master faders to adjust the
desired volume setting. Otherwise, high sound levels caused by unintentional playback of a program
source could be the result, which might cause hearing damage.
This Quick Start Manual outlines setup and operation of
the D 11A connected to a DYNACORD CMS mixer.
1. Place the D 11A, mounted on pole-mount stands to
the left and to the right. The lower edges of the
speaker systems should be approximately 1,8 meters
above the audience to provide sufficient coverage
and to prevent that listeners nearby are subject to
extreme sound levels.
2. Using suitable XLR-type cables connect the Master
Outputs of your mixing console, e.g. DYNACORD
CMS 1000, to LINE IN of the D 11A. Position the mas-
ter faders on the mixer to their minimum setting.
Now, switch on the mixer.
3. Connect the D 11A to the mains outlet using the sup-
plied mains cord. Plug the connector into the MAINS
IN socket. Use the Mains switch to power-up the
D 11A.
4. Set the level controls VOLUME and LINE TRIM of the
D 11A to 0dB.
5. Connect an audio source, e.g. CD player, to a line

This may happen when the speaker is operated in very high
ambient temperatures and the enclosure is exposed to di-
rect sunlight. Always ensure adequate cooling and appro-
priate shade to keep the ambient temperature around the
product within the specified operating temperature range.
level input of the mixer, e.g. CMS 1000. Set all rotary
controls of the mixing console input channel to their
center position. Adjust the input channel's 'Gain'
control so that the Peak LED should not light at all or
blink only once in a while.
6. Slowly raise channel fader and master faders on the
mixing console to the desired positions – i.e. volume
settings.
7. Your system is now ready for operation. Individual
sound adjustments necessary can be made using the
controls of the mixer's corresponding input chan-
nels.
8. Now, have fun with your D 11A system!
9. After use, first switch off the D 11A and then the mix-
ing console, so that distracting power-off noise will
not occur. When using a DYNACORD CMS mixer, no
power-off noise will be output from the 'Master Out-
puts'. This allows switching off the mixer first with-
out a problem.
