Congratulations! In buying a DYNACORD SUB 800A you decided on getting one of today’s most advanced active subwoofers incorporating most sophisticated technology.
The active 15" subwoofer SUB 800A with integrated 800 watts power amplifier has been specially designed to provide fundamental bass support for professional full-range and multi-channel cabinets. Through the integrated electronic frequency crossover of the SUB 800A setting up an active stereo multi-channel system is truly simple. The stereo audio signals for the mid-high range cabinets are provided via the MID-HIGH outputs on the SUB 800A. Additionally provided are all connection facilities for using the SUB800A as active mono subwoofer in active 2-way or “add-on operation”. Manufactured from Mediapan and housing a high-performance Electro-Voice DL15Y woofer, the SUB800A withstands even the hardest strain during transport and operation. While input connection is also possible via phone type jacks, all input and output signals are output via professional XLR-type connectors.
The integrated High-Efficiency 800W power amplifier optimally matches the DL15Y woofer offering highest dynamic and audio performance and ensures at the same time that the DL15Y woofer is always operated in its optimum operation range. Extensive protection circuitry like TBC, DC/HF-protection, audio limiter, Back-EMF protection and thermal protection are employed to securely monitor the compliance to these operation limits guaranteeing that the SUB 800A provides outstanding performance even under most demanding and most unfavorable conditions. The SUB 800A is also especially suitable for numerous applications in the rental business. When compared to usual Class-AB-operated amps and because of utilizing Class-H High-Efficiency technology the power amplifier produces significantly less power loss, which additionally reduces thermal stress of all components. Employing fans to ensure thermal stability is not necessary because of the consequent realization in Class-H technology and use of comprehensively dimensioned cooling profiles. The enclosure is sealed with extremely hardwearing black structure lacquer finish, while a robust powder-coated steel grille provides protection for the Electro-Voice DL15Y woofer against mechanical damage. All controls and the cooling profiles of the power amp module are recessed to provide optimum protection for the sensitive parts of the SUB 800A even during transportation. Two stable carrying handles, four castors and an integrated threaded pole-mount stand flange allow comfor- table transportation and optimum, space saving installation. Because of its versatility, the SUB 800A can be easily integrated into any existing sound reinforcement installation.
Unpacking and Warranty
Open the packing and carefully take out the SUB 800A. Remove the protective foil from the carrying handles. A mains cord and the warranty card are supplied in addition to this owner’s manual. Please make sure that all details are filled in on the warranty card. Only a completely filled in warranty certificate entitles you to stake any warranty claims. The SUB800A comes with a warranty of 36 months, starting from the date when receiving the good from your dealer. Therefore, keep the original invoice together with the warranty certificate at a safe place.
Set up and Connections
Place the SUB 800A on an even ground if possibly by using the supplied rubber feet to ensure safe operation. Make sure to check the stability of the system when using pole-mount stands. Do not cover the heat sink on the subwoofer’s rear during operation. Otherwise, the SUB 800A will enter protection mode because of thermal overload. Although this provides reliable protection for the subwoofer, sound reproduction is muted until the normal operation mode is regained. Mains power is supplied via the Neutrik’s professional PowerCon connector system and by use of an extreme long (5m) mains cord. This ensures an absolute secure and reliable power supply connection. However, with large installations consisting of several active cabinets, the use of high-quality mains distributors that allow high power consumption and offer reliable protection throughout the entire system is strongly recommended.
Before establishing the mains connection for the first time, make sure that the SUB800A’s operation voltage setting, which can be found on a label next to the mains switch, corresponds to your local mains network.
