WHAT DOES LD SYSTEMS DynX® DSP MEAN?
DSP is an acronym that stands for digital signal processing. DynX® includes the Limiter, EQ, Compressor, and Crossover functions. Digital signal processing ensures optimal audio playback with maximum clarity while protecting the PA system from overloading.

WHAT EXACTLY DOES DynX® DSP DO?
The Limiter function protects the speaker and prevents overload-induced distortion. Separate limiters for the bass, mid, and treble regions limit the signal if the level exceeds a value that could have negative effects. Each limiter is optimized for one of the three seamlessly connected frequency ranges (multi-band limiter). This allows the system to be operated at an overall higher sound pressure since extreme signal peaks are automatically limited so that the master volume does not have to be reduced.
The multi-band EQ handles the entire frequency range and optimizes the system’s overall sound.
Depending on the frequency range, the crossovers divide the audio signal into the respective speakers, i.e. the subwoofer, midrange tweeter, and tweeter of the array column. The amplitude and run-time optimization of the crossovers also ensure that all frequencies are evenly emitted and reach listeners at the same time.

STAND ADAPTER

The speakers are equipped with a stand adapter with a stand connection with an angle of 0° (rear position) and a stand connection with a tilt angle of 5° (front position). Examples of use: Use the stand adapter with an angle of 0° for emitting sound to a public audience and the stand adapter with a tilt angle of 5° for emitting sound to a seated audience.

USE AS A FLOOR MONITOR

The speakers can also be used entirely as floor monitors thanks to the monitor DSP preset, the rotatable tweeter, and its all-purpose housing. Nonslip rubber washers ensure secure positioning. The monitor angle is positioned at 55°.

ROTATE TWEETER BY 90°

The tweeter can be rotated 90° when the speaker needs to be used in situations where it is installed horizontally or used as a floor monitor.

IMPORTANT!
Warning: Risk of electric shock! Dangerous voltages are present inside the device! Opening the device and rotating the high-frequency horn requires specialist knowledge and may only be carried out by specially trained personnel! If you are not suitably qualified, do not attempt the procedure yourself. Refer instead to a qualified professional.

Take care when opening the device and rotating the high-frequency horn, in order to avoid damage to the speaker and injury to persons. Follow each step of the instructions exactly. The manufacturer shall not be liable for any damage to devices or injury to persons resulting from improper handling.

1. Fully disconnect the speaker from the mains (pull out the mains plug) and wait for approx. 3 minutes before starting work!
2. Disconnect all cables from the speaker.
3. Place the speaker in its slanted monitoring position, remove the front grille from the housing (5 x 2.5-mm internal hex screws on left and right of the housing).
4. Loosen the 4 screws that secure the high-frequency horn (see figure A).
5. Carefully lift the horn and rotate it through 90°, taking care not to damage the tweeter driver cable.
6. Feed the tweeter driver cable into the retainer nut next to the securing lug and replace the horn in the retainers. Ensure that the cable is not pinched.
7. Carefully secure the horn with the screws and re-install the front grille on the housing.
