The inputs INPUT A & INPUT B of the CL series are electronically balanced. The voltage gain of all models is set to 32 dB (constant gain). This results however in different input sensitivities for the different models (see table), but the level adjustment of active crossovers or signal processors in multi-way systems is much easier. Power amplifi ers with different output power can be changed without consideration, the crossovers have not to be adjusted due to the constant amplifi cation of the whole unit line. If external voltage limiters are used, they should be set to the used power class with consideration of the connected speaker systems. The XLR-type connectors OUTPUT A & OUTPUT B are prepared for „through-connecting“ input signals to additional external power amps. The input signal is directly routed to these output connectors. There are no repeaters or other electronic components within that signal path. Accordingly, input and output connectors of the corresponding channel are interconnected in parallel, offering permanent electrical connection, without regard to the setting of the Power-ON switch.

Although having XLR-type output connectors, some mixing console models provide unbalanced output connection only. When using mixers with unbalanced outputs, bridging PIN1 and PIN3 of the power amp’s input connectors or leaving PIN3 of the cable’s plugs unconnected is necessary. Otherwise, when feeding in unbalanced audio signals via PIN3 (b, -, „cold“) and PIN2 (a, +, „hot“), strange humming and RF-interference may occur, which very likely will damage the power amplifier and/or the connected speaker cabinets.

NF-CONNECTION CORDS

Choosing high-quality balanced cables (two conductors for the audio signal plus seperate shielding mesh) with XLR-type connectors are recommended for LF-signal connection. Although connecting un- balanced cables to the power amplifi er inputs is possible as well, using balanced cables is always pref- erable. A great number of today’s audio appliances employ balanced outputs. With balanced cabling, the shield connects all metal enclosure parts and therefore effi ciently eliminates the introduction of ex- ternal interference – mostly noise and hum.

PARALLEL

The input connectors of channel A and channel B are electrically connected in parallel when the selector switch is set to PARALLEL. However, individually controlling the volume of both channels is still possible via the corresponding level controls A and B.

DUAL

If the selector switch is set to DUAL, the audio signals of channels A and B are independently amplifi ed.

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.
