FRONT PANEL

Use the POWER switch, located on the front panel’s, right side to switch the appliance’s power on. The soft-start function limits against current inrush peaks on the mains, which in addition prevents the mains line protection switch from activating during power-on. The loudspeaker outputs are activated via relay switching with a delay of approximately 2 seconds to effi ciently attenuate eventual power-on noise. The PROTECT LED lights during the delay time and the fans run at maximum speed. This is normal, con- fi rming the correct operation of the protection circuitry.

POWER-indicator not lighting are: the appliance is not connected to the mains or the primary fuse is defective.

The PROTECT LED indicating that one of the internal protection circuits against thermal overload, short-circuit, Back-EMF, RF-occurrence at the output, etc., has been activated. The output relays interrupt the connected loads from

the power amps while input signals are interrupted as well, preventing the connected loudspeaker systems and the power amplifi ers themselves from being damaged. Whatever caused the fault – e.g. a short-circuited speaker cable – needs to be reme- died. In case of thermal overload you have to wait until the power amplifier automati- cally regains normal operation.

he SIGNAL LED lights as soon as an audio signal of approximately 30dB below full odulation is present at the output. The LED is dimmed when speaker cables are hort-circuited or a protection circuit has been activated.

he 0dB LED lights whenever the power amplifi er is driven at its maximum. Higher put voltage does not result in higher peak output voltage. In addition, the 0dB dicator comes in handy when adjusting external limiters.

his indicator lights as soon as the integrated dynamic audio signal limiter is ctivated and the power amplifi er is driven at the clipping limit or generally at its aximum capacity. Short-term blinking is not a problem, because the internal limiter controlls input levels of up to +21dBu down to a THD of approximately 1%. If, on the other hand, this LED lights constantly, reducing the volume is recommended to prevent the loudspeaker systems connected from being damaged by probable overload.

Detent potentiometers scaled in dB (steps of 1dB) for adjusting the power amp’s overall volume. To prevent distortion in mixing consoles connected to your CL-Series amp, setting these controls to a value between 0dB and -6dB is generally recommended. The dB-scale provides direct indication of the control attenuation applied to the fi xed internal amplifi cation.

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.
