Power AMP Output Connectors, Bridged Mode

POWER AMP OUTPUT CONNECTORS

Power amp output connection for the two channels A (left) and B (right) is provided via SPEAKON-type output connectors.

A plastic cover to prevent inadvertent erroneous connection protects the BRIDGED OUT connector. Make sure to remove the cover only when actually operating the power amplifi er in Bridged-Mode.

CAUTION!

Pins 2+/2- of the CHANNEL A SPEAKON output, which normally are not in use, are also connected to output B to ensure comfortable connection of 2-way speaker cabinets (e.g in Bi-Amping Mode) when using 4-wire Speakon cables.

To prevent short-circuit and/or to protect your speaker systems from being damaged when connecting the cabinets, please make sure to mind the Low- and High channels’ specifi c pin-assignments!

If, for example, the subwoofer audio signal is used to feed a tweeter, it is more than likely that this will instantly destroy the HF-driver’s coil.

WARNING:

The speaker output terminals are marked with a symbol “ ”, which signifies that these terminals are hazardous live and present a risk of electric shock to the user.

BRIDGED MODE

With the BRIDGED-MODE switch being engaged, using the channel A input for audio signal feed is mandatory, since input B provides no function. While the amplifi er of channel A operates as usual, the audio signal is internally inverted and routed to the amplifi er of channel B. Both amps – A and B – now

work in push-pull operation to provide doubled output voltage at the BRIDGED-OUT connector.

The regular output voltage of each amplifi er channel A / B is still present at the corresponding output connector CHANNEL A or CHANNEL B. However, using these signals is not recommendable because of the aforementioned phase inversion. Operating the power amp in Bridged Mode with loads of 2ohms connected is not allowable.

CAUTION: Extremely high voltages might be present at the BRIDGED OUT connector during Bridged-Mode operation. The connected loudspeaker systems have to be capable of handling such high voltages. Please make sure that power handling specifications as stated in the docu- mentation supplied with your speaker systems match the specifications of the power amplifier.

GROUND-LIFT SWITCH

The ground-lift switch allows eliminating noise loops. If the power amplifier is operated together with other equipment in a 19“ rack-shelf, setting the switch to its GROUNDED position is recommended. If the power amplifi er is operated together with appliances with differing ground potentials, set the switch to its UNGROUNDED position.

MAINS INPUT

Under normal circumstances, the mains fuse only blows in case of fault. Replacing the fuse is only permissible when using a new fuse of the same type with identical amperage, voltage and blow characteristics. If the mains fuse blows more often, please contact an authorized service centre.

The high-performance mains cord supplied with your power amplifi er complies to applicable safety regulations, plus that its diameter corresponds to the power

amp’s power output capacity. Make sure to use the supplied mains cord for connecting the power amp to the mains. Using mains cords with smaller diameters results in higher leakage and consequently re- duced maximum power output capacity.

At 100V and 120V units the mains fuse is installed internally. This is fore safety reasons. In case of a blown mains fuse please contact a qualifi ed service personnel for servicing.

CL 1200, CL 2000 specifications

The Dynacord CL 1200 and CL 2000 are robust power amplifiers known for their superior performance and reliability in demanding sound reinforcement applications. These amplifiers are designed with cutting-edge technology, making them suitable for a variety of professional settings including live concerts, installations, and corporate events.

One of the main features of the CL series is their Class D amplification technology. This design not only provides high efficiency but also significantly reduces energy consumption and heat generation compared to traditional Class AB amplifiers. The result is a lightweight and compact unit that delivers powerful audio output without the burden of excessive weight.

Both the CL 1200 and CL 2000 models differ primarily in their output power capabilities. The CL 1200 is capable of delivering up to 1200 watts per channel, while the CL 2000 can reach an impressive 2000 watts per channel. This makes them adaptable to different venue sizes, ensuring that there is ample power for various performance needs.

Another key characteristic of both models is their versatile connectivity options. These amplifiers come equipped with XLR and TRS inputs as well as binding post and speakON outputs, making them compatible with a wide range of sound systems and speaker configurations. This flexibility is crucial for audio professionals who need to adapt their setup quickly in different environments.

Advanced protection features are also integrated into the design of the CL amplifiers. They feature temperature control, short circuit protection, and overload protection, ensuring that the equipment remains safe and operational under various conditions. This reliability is paramount for live sound applications where equipment failure can have serious consequences.

The user-friendly interface allows for easy setup and operation. The built-in LED indicators provide real-time monitoring of the amplifier's status, helping users to quickly identify any issues that may arise. This assists audio engineers in maintaining optimal performance throughout events.

In summary, the Dynacord CL 1200 and CL 2000 amplifiers are characterized by their powerful output, Class D technology, flexible connectivity, and advanced protection features. These amplifiers are engineered to meet the demands of professional audio applications, making them a preferred choice for sound reinforcement solutions. With robust performance and reliability, the CL series stands out as a leading option in today's competitive audio market.
