D 8A
1 Introduction
The DYNACORD D 8A is a powered, biamped, light-weight
and extremely robust high-performance professional 8” 2way plastic cabinet for use in professional sound
reinforcement applications. With a variety of suspension
accessories and conservative cosmetics, the D 8A is also
ideally suited to be used in demanding fixed installations.
The cabinet is manufactured from ABS and therefore is extremely resistant against abuse on the road. For low frequencies a DYNACORD DND8200-8 is used. The ElectroVoice DH 3 driver is used for the projection of mid and high
frequencies. The Constant-Directivity HF horn has been integrated into the baffle by CAD methods. Nominal coverage angle of the cabinet is 90° * 90°, horizontal * vertical
respectively.
The built-in digital power amplifiers are working in biamped operation and are controlled by an electronic x-over
circuit that has been designed to optimally match the
transducers’ acoustic characteristics. The D 8A is ideally
suited for applications as full-range cabinet or as Mid-Hi
cabinet in high-performance satellite systems. EASE and
ULYSSES data allow fast and precise simulations.
The line-level input signal can be connected to the cabinet
by means of an XLR plug or a standard phone plug. Additionally an microphone level input signal can be connected
by means of an XLR plug and adjusted using the microphone level control MIC. The master signal can be daisychained to a second D 8A cabinet via a regular XLR microphone cable. The built-in level control MASTER allows easy
adjustment of the required sound pressure level.
The D 8A is connected to the mains via a locked IEC inlet
that guarantees a hassle-free operation. Extremely durable
acoustic foam mounted to a strong powder-coated steel
grille protects the loudspeaker components against any
mechanical damage. A protective cover is available as an
option.
Packing the cabinet like it was packed by the manufacturer
guarantees optimum protection from transport damage.
1.2 Warranty

4 LIMIT INDICATOR (LIMIT)
Brief blinking of the LIMIT LED indicates that the
power amplifier of the D 8A is operated at its limits.
Short-term blinking is uncritical, because the integrated limiter compensates minor distortion. Constant lighting of the LED indicates that the sound is negatively
affected. Reducing the output volume is strongly recommended.
ASTER LEVEL CONTROL (MASTER)
5 M
Level control for adjusting the
power amp’s overall amplification.
ICROPHONE LEVEL CONTROL (MIC)
6 M
Level control for adjusting the amplification of the signal at the MIC IN input.

If the D 8A is used as a fullrange sys-
tem, select FULLRANGE (button not
pressed).
If a subwoofer without a low-cut signal output is used, i.e.
the identical audio signal is used for the D 8A and the
subwoofer, select LO-CUT (button pressed) for activating
the internal low-cut filter of the D 8A. If the D 8A is connected to the HI OUT output of a subwoofer with integrated low-cut filter, select FULLRANGE to avoid having the
two low-cut filters of the subwoofer and D 8A in series.
The setting LO-CUT can also be used for monitor or delay
applications, when a high bass level is not necessary.
NPUT CONNECTOR FOR AUDIO SIGNAL (LINE IN)
9 I
Electronically balanced input for the
connection of a line level signal source such as mixer, signal processor,
etc. Establishing a connection is possible via phone or XLR-type plugs.
Whenever possible, balanced signal
feed is always preferable to guard against potential noise
or HF-interference.
CAUTION: Before making any connections or discon-
nections, make sure to set the level control
to the counterclockwise stop.
UTPUT CONNECTOR (MASTER OUT)
10 O
The output connector provides the
Master Signal (Line+Mic) for ”carrying through“ the input signal. The
level of the output signal is independent of the setting of the Master level control (”Pre Fader”).
2.2 Cooling
This is a powered speaker 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 direct sunlight. Always ensure adequate cooling and appropriate shade to keep the ambient temperature around the
product within the specified operating temperature range.
2.3 System Setup
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 8A and use
the MASTER 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 8A connected to a DYNACORD CMS mixer.
1. Place the D 8A, 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 8A. Position the master faders on the mixer to their minimum setting.
Now, switch on the mixer.
3. Connect the D 8A to the mains outlet using the supplied mains cord. Plug the connector into the MAINS
IN socket. Use the Mains switch to power-up the
D8A.
4. Set the level control MASTER of the D 8A to 0dB.
5. Connect a audio source, e.g. CD player, to a line 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
channels.
8. Now, have fun with your D 8A system!
9. After use, first switch off the D 8A 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.
2.4 Rigging
CAUTION: We expressly point out that the relevant safety regulations must be observed for “flying“ loudspeaker
systems. It is imperative that qualified expert advice is sought.
CAUTION: Suspending any object is potentially dangerous and should only be attempted by individuals who have
a thorough knowledge of the techniques and regulations of rigging objects overhead. Dynacord
strongly recommends that D 8A speakers be suspended taking into account all current national, federal, state and local regulations. It is the responsibility of the installer to ensure that D 8A speakers are
safely installed in accordance with all such regulations. If D 8A speakers are suspended, Dynacord
strongly recommends that the system be inspected at least once a year. If any sign of weakness or damage is detected, remedial action should be taken immediately.
