D 8A

1 Introduction

The DYNACORD D 8A is a powered, biamped, light-weight and extremely robust high-performance professional 8” 2- way 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.

D 8A

4 LIMIT INDICATOR (LIMIT)

10 OUTPUT CONNECTOR (MASTER OUT)

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 ligh-

ting of the LED indicates that the sound is negatively affected. Reducing the output volume is strongly recommended.

5 MASTER LEVEL CONTROL (MASTER)

Level control for adjusting the power amp’s overall amplification.

6 MICROPHONE LEVEL CONTROL (MIC)

Level control for adjusting the amplification of the signal at the MIC IN input.

7 INPUT CONNECTOR FOR MICROPHONE AUDIO SIGNAL (MIC IN)

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.

Audio input for connecting an balanced audio signal with microphone level.

CAUTION: Before making any connections or disconnections, make sure to set the level control to the counterclockwise stop.

8 MODE SELECTION SWITCH (LO-CUT/FULLRANGE)

						If the D 8A is used as a fullrange sys-
LO-CUT						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.

9 INPUT CONNECTOR FOR AUDIO SIGNAL (LINE IN)

Electronically balanced input for the connection of a line level signal sour-

ce 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 disconnections, make sure to set the level control to the counterclockwise stop.

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

D 8A.

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.

D 8A

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.
