IMPORTANT SAFETY INSTRUCTIONS The lightning flash 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 sufficient magnitude to constitute a risk of electric shock to persons.
DESCRIPTION Congratulations! With buying a DYNACORD CL-SERIES power amplifier you have chosen an appliance 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 employing low-leakage toroidal transformers and the consistent use of Class-H technology provide extensive headroom far above the stated nominal output.
DESCRIPTION UNPACKING & WARRANTY Carefully open the packaging and take out the power amplifier. Next to the power amplifier itself, the package also includes this owner’s manual, a mains cord and the warranty certificate. Keep the original invoice, which states the purchase/delivery date together with the warranty certificate at a safe place. INSTALLATION NOTES Generally, installing or mounting power amps should be carried out in a way that guarantees continuously unopposed front-to-rear air circulation.
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 efficiently attenuate eventual power-on noise. The PROTECT LED lights during the delay time and the fans run at maximum speed.
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.
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 amplifier in Bridged-Mode.
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).
MAINS OPERATION & RESULTING TEMPERATURE CL1600 idle (1) Max. Output Power @ 8Ω (1) Max.
