Installation Notes, Before The First Operation

Installation Notes

Generally, it is important to install the power amplifier in a way, that ensures unhindered front-to-rear air circulation.

When installing the power amplifier in a closed rack-shelf system, please make sure that adequate air-flow is guaranteed. The space between the rear panel of the amplifier and the inner wall of the rack-case has to be at least 60 mm x 330 mm. A free space of at least 100 mm above the rack-shelf system is needed to provide sufficient air circulation. Since, during operation, the temperature inside the rack system could easily rise up to 40° C, the maximum allowable ambient temperatures of the rest of the incorporated modules and appliances within a specific rack-shelf system have to be taken into careful consideration.

When mounting the power amplifier insi- de of a closed rack system, it is recom- mended to use special rack-rails or optionally available rack-mount ears NRS 90235 (112733) to prevent bending of the appliance’s front panel.

Note For maintained trouble-free operation of the appliance, the maximum admissible ambient temperature of +40°C is not to be exceeded.

The amplifier has to be protected from:

-water drops or splashes

-direct sunlight

-high ambient temperatures and the direct radiation of heat sources

-high humidity and moisture

-heavy dust

-massive vibrations

Moving the amplifier from a cold into a warm environment can result in the occurrence of condensation on inner parts. Operating the appliance is only permissible after it has accommodated to the altered temperature (approximately after one hour).

Should any foreign solid parts or liquids inadvertently intrude the enclosure, immediately unplug the device from the power source and have it checked at a DYNACORD service center, before further use. Cleaning the appliance should not be performed using chemical solvents or sprays, as this might damage the finish and could even cause hazard fire.

Before The First Operation

Before switching the amplifier’s power on, the included mains cord has to be connected to a 230 V - 50/60 Hz wall outlet. On the appliance itself, the cord has to be connected to the 3-pole mains socket.

To remotely start the amplifier, it is necessary to connect an external 24 V power source to the terminal strip POWER REMOTE. Providing correct connection and with an external power supply being present, the POWER ON indicator will light and the power amplifier is ready for operation.

The mains switch POWER on the rear of the appliance is meant for service and maintenance purposes only. Through bridging the mains switching relay this option provides the possibility to operate the amplifier without an external 24 V power supply connected.

Caution The mains switch POWER on the rear of the appliance is only meant for maintenance. Remotely switching off the device is not possible when the POWER switch is engaged.

The DPA-Series power amplifiers employ power-on switching delays of approximately 2 seconds.

DPA 4260, DPA 4245 specifications

Dynacord, a renowned name in professional audio equipment, has established a reputation for delivering high-performance amplifiers that meet the rigorous demands of live sound and installation applications. The DPA 4260 and DPA 4245 models stand out in their lineup, featuring advanced technologies and robust characteristics that set them apart in the competitive audio landscape.

The Dynacord DPA 4260 is a powerful four-channel amplifier that offers an impressive output of up to 2,600 watts, designed to drive a wide range of speakers effortlessly. One of its main features is the implementation of a sophisticated DSP (Digital Signal Processing) technology, which provides comprehensive control over audio parameters such as EQ, crossover, delay, and limiter settings. This allows users to optimize the sound output for various environments, ensuring clarity and fidelity in the audio performance.

In addition to DSP, the DPA 4260 is equipped with an advanced Power Factor Correction (PFC) system. This technology not only enhances the amplifier's efficiency but also ensures stable performance even under varying load conditions. The amplifier's robust build quality and efficient heat dissipation design make it suitable for extended operation in demanding venues.

On the other hand, the Dynacord DPA 4245 is another impressive model offering a slightly lower output of 1,400 watts but packed with its unique set of features. Like the DPA 4260, it benefits from the same DSP capabilities, allowing for detailed sound manipulation and tuning. This is particularly useful for sound engineers looking for precision in their audio setups.

The DPA 4245 also showcases versatility in its operation, featuring a selection of operating modes to accommodate different configurations, including bridge mode for driving larger loads. Its lightweight design makes it easy to transport and install without compromising on power or performance.

Both models come with comprehensive connectivity options, ensuring compatibility with various audio systems and setups, facilitating seamless integration into existing infrastructures. The front panel allows for easy monitoring, featuring LED indicators that display operational status and signal integrity.

In conclusion, Dynacord's DPA 4260 and DPA 4245 amplifiers exemplify cutting-edge technology and robust construction in the world of professional audio. With their powerful outputs, advanced DSP capabilities, and flexible configurations, these amplifiers are designed to meet the demands of professionals seeking reliable and high-quality audio solutions in live sound reinforcement and installation applications. Whether for touring, installations, or events, these amplifiers ensure a professional sound experience.
