SAFETY COMPONENT (HAS TO BE REPLACED WITH ORIGINAL PART ONLY)

Congratulations! In buying a DYNACORD SUB 800A you decided on getting one of today's most advanced active subwooferors 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 comfortable 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.

Quick Start

Caution: Before switching on the power of the SUB800A always set the LEVEL control to its counterclockwise stop. A playing sound source could otherwise lead to extreme output levels.

This Quick Start Manual outlines the set up and operation of a SUB800A used as add-on subwoofer together with a PowerMate (see configuration examples). The operation procedures are equivalent for other mixers.

1. Set up your PowerMate system as usual and connect a signal source to the power mixer (e.g. CD Player or microphone).
2. Place your SUB800A somewhere between your full-range cabinets.
3. Set the SUB800A's LEVEL control to its counterclockwise stop and connect the unit to a wall outlet using the supplied PowerCon mains cord.
4. Use a stereo phone plug cable to connect the PowerMate's MONO OUT to the SUB800A's L/MONO INPUT.
5. Close the PowerMate's MONO OUT fader all the way.
6. Be sure to switch on the PowerMate first and then the SUB800A. Switching on the SUB800A last is recommended. Otherwise, unwanted power-on noise might occur. When switching off your equipment, please proceed in the opposite order, i.e. switch off the SUB800A first.
7. Set the SUB800A's LEVEL control to its center position (0dB) and start the playback of the desired signal audio source.
8. After adjusting the desired acoustic output level of the full-range cabinets using the PowerMate's master fader, establish volume setting for the subwoofer using the MONO OUT fader.

Input L/Mono, Input R

Electronically balanced inputs for the connection of high-level signal sources such as mixers, signal processors, etc. Establishing the connection is possible via phone or XLR-type jacks. Balanced connection is recommended to prevent noise or HF-interference.

Caution: Before connecting or disconnecting any plugs, make sure to set the level control to its counterclockwise stop, which prevents the system, the audience and yourself from being stressed by nasty contact noise.

The input section of the SUB800A also allows mono sub operation. The stereo signal is fed to the L and R inputs and the low-frequency range signals of both channels are summed prior to being processed in the power amplifier section. All other applications use only the (L)/Mono input. Please also refer to the chapter "SETUP EXAMPLES".

Parallel Outputs L/R

Parallel connected to the main inputs these sockets are used for "carrying through" the input signals.

Mid-High Outputs L/R

The input signal is split via the integrated electronic crossover (PowerMax, 100Hz). Low-frequency signals are routed to the internal power amplifier of the SUB800A while high-frequency signals are present at the Mid-High outputs for further distribution to external power amps or active mid-high range cabinets.

LEVEL

This control sets the output volume of the SUB800A in a range between - dB and +10dB . The internal power amplifier provides a nominal input sensitivity of +6dBu .

STATUS INDICATORS

These indicators provide information about the actual operational state of the SUB800A's internal power amplifier.

SIGNAL indicates that an audio signal is present at the input and that it is output.

LIMIT When lit this indicator signals that the internal power amplifier is actually operated at the borders of clipping. Short-term blinking is uncritical, because the amp's audio limiter keeps distortion under control, so that the sound is unaffected. Input overdrive, which results in sound degradation, is a probable cause for a continuously lit indicator. To prevent this from happening, reduce the input level.

TBC lights when the power amplifier's "Thermal Brain Circuit" is activated. During dynamic peaks the integrated power amplifier is capable of producing output levels that clearly exceed its stated nominal output capacity. Therefore, the SUB800A employs a TBC-

circuit (Thermal Brain Circuit), which simulates the thermal behavior of the speaker's voice-coil, automatically reducing the energy fed to the speaker system on the occurrence of thermal overload.

PROTECT Lights when one of the multiple comprehensive protections, e.g. against thermal overload, HF, DC or Back-EMF of the power amplifier is activated. Preventing the woofer from being damaged, it is shutoff via relays in the protect mode. Additionally, the input level is being reduced. During power-on the PROTECT LED lights for approximately 2 seconds, which is normal. This only indicates that all protection circuitry has been activated properly.
