2.3 Power amplifer and cooling
This is a powered subwoofer with a very high efficient
amplifier 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.
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
PSD within the specified operating temperature range.
CAUTION: The rear panel of the PSD serves as a heat
sink for the power amplifier. Certain body
parts may be hot during operation.
2.4 Quickstart
This quickstart explains installation and operation of two
PSD 215 + TS 400 subwoofer satellite systems used to-
gether with a DYNACORD CMS mixer.
CAUTION: After system installation is complete, make
sure to first power on the mixing console
and to position the master faders at their
lowest setting before switching the power
of the PSDs to ON. Use the output faders to
establish the desired volume setting. Other-
wise, switching and power-on noise or the
high level audio signal of an inadvertently
playing audio source could result in high
acoustic outputs, that in some cases might
even lead to hearing damage.
1. Set up your satellite cabinets on the left and right
hand side on pole-mount stands (using the M20
thread on top of the enclosure) with the lower edges
of the speaker systems being approx. 1 meter above
the heads of the audience. In this way you will gain
longer throw and the listeners in the front rows are
safe from high acoustic level peaks.
2. On each side connect the satellite speaker to the
TOP SPEAKER OUTPUT on the rear of the PSD 215
using suitable Speakon speaker cables.
3. Connect the Master Outputs of your mixer to the
INPUT on the left or right PSD 215 using appropriate
XLR type cables. Position the mixer‘s master faders
at their lowest setting and afterwards power on the
mixer.
4. Connect the PSD 215 to the mains outlet using the
supplied mains cord. Plug the connector into the
MAINS IN socket. Use the Mains switch to power ON
the PSD, the ON LED lights green.
5. After the first power on of the PSD 215 the Preset
Select dialog automatically appears in the display (to
open the dialog manually, press the PRESET function
key).
6. Select the TS 400 preset from the preset list by
turning the MENU/ENTER rotary encoder.
7. Press the MENU/ENTER rotary encoder to load the
preset.
8. Press the BACK function key to exit the Preset Select
dialog.
9. Repeat steps 5 to 8 at the second PSD 215.
10. Connect an audio source, e.g. CD player, to a line
level input of the mixer. 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.
11. Slowly raise channel fader and master faders on the
mixing console to the desired positions – i.e. volume
settings.
12. The tonal balance between bass and mid-high range
can be adjusted using the SUB Level parameter (see
page 8) or the System Alignment dialog (see page 9)
of the PSD 215.
13. Your system is now ready for operation. Individual
sound adjustments necessary can be made using the
System Equalizer dialog (see page 9) of the PSD.
14. Now, have fun with your PSD system!
15. After use, first switch off both PSD 215 and then the
mixing 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
Outputs‘. This allows switching off the mixer first
without a problem.
