CL 1600 CL 1200CL 800

Compact Linear Precision Power Amplifiers

The new CL Series amplifiers combine outstanding audio performance with maximum reliability and operating safety, as well as being noticeably lighter than equivalent power amplifiers.

As is tradition with the Dynacord amplifier heritage, a large amount of headroom above the specified nominal output has been achieved through the use of optimized power supplies with low dispersion torroidal transformers and class H technology (CL 800 class AB). Considerable weight reduction and energy conservation due to less heat dissipation are also a few of the advantages to the new CL Series.

As expected from a Dynacord design, the CL Series amplifiers can handle the toughest on the road abuse. Dynacord’s protection package in every amplifier is matched by no other manufacturer, and the CL Series is no exception. They are reliably protected for thermal capacity, output overload and short cicuit, as well as high frequency osciliation and DC voltage in the output stage. A ´soft start´ relay circuit is employed to prevent annoying ´pops´ at start up and an additional circuit is used to limit current draw at start up, protecting breakers and fuses.

Dynacord amplifiers constantly monitor inputvs outputsignal by means of superfast audio processors which send –incase of non linear operation – control parameters to the limiters. In order not to affect the dynamic range of music signal this circuit functions as an RMS limiter by affecting the input gain, reserving the full dynamic headroom of the amplifier.

Thermal stability is provided by a 3-stagefan with the lowest possible noise level. The inputs are electronically balanced and implemented on XLR connectors, and Direct Outs for looping the signal are also standard. Input routing permits a choice between Mono and Stereo modes. Mono bridged mode is also easily configured thanks to the separate Bridged Out

connector and the Bridged Mode switch.

Highly precise, yet rugged potentiometers are recessed in the

front panel to prevent physical damage and offer level control scaled in single decibel increments. The clearly laid out LED display shows the operating conditions of the power amplifiers by means of Power, Protect, Signal and Limit indicators.

The electronically balanced XLR input and output connectors are designed for direct operation with professional mixing consoles and signal processors. The complete CL Series power amplifier are designed for `Constant-Gain´structure of 32dB. The power outputs for Channels A and B as well as the Bridged Out are available on reliable Speakon connectors. There is aGround-Liftswitch on the rear panel to separate the signal ground from the chassis ground to eliminate ground loops.

All CL power amplifiers can normally be operated with loads as low as 2 ohms and in bridged mode down to a minimum of 4 ohms with complete operational security.

For rackmount of the CL Series amplifiers there are differnt long ´Rear-Rackmount´rails as accessories available.
