IMPORTANT SAFETY INSTRUCTIONS The lightning fl ash with arrowhead symbol, within an equilateral triangle is intended to alert the user to the presence of uninsulated “dangerous voltage“ within the product’s enclosure that may be of suffi cient magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and “maintenance” (servicing) instructions in the literature accom

DESCRIPTION Congratulations! With buying a DYNACORD CL-SERIES power amplifi er you have chosen an appli- ance that employs most advanced technology. CL-Series power amps combine outstanding audio performance, highest reliability and operational safety. The audio performance of CL power amps are simply extraordinary. Optimised power supply units em- ploying low-leakage toroidal transformers and the consistent use of Class-H technology provide exten- sive sive headroom headroom far far above abo

DESCRIPTION UNPACKING & WARRANTY Carefully open the packaging and take out the power amplifi er. Next to the power amplifi er itself, the package also includes this owner’s manual, a mains cord and the warranty certifi cate. Keep the original invoice, which states the purchase/delivery date together with the warranty certifi cate at a safe place. INSTALLATION NOTES Generally, installing or mounting power amps should be carried out in a way that guarantees continu- ously unopposed front-to-rear

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 maxi

REAR PANEL INPUT A / INPUT B 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

REAR PANEL 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 co

MAINS OPERATION & RESULTING TEMPERATURE MAINS OPERATION & RESULTING TEMPERATURE The following tables allow determining power supply and cabling requirements. The power drawn from the mains network is converted into output power to feed the connected loudspeaker systems and into heat. The difference between power consumption and dispensed power is called power dissipation (Pd). The amount of heat resulting from power dissipation might remain inside of a rack-shelf and needs to be diverted usi
