Dynacord CL1200 Compact Linear Precision Power Amplifier

Dynacord CL1200 Compact Linear Precision Power Amplifier

The Compact Linear Precision Series power amplifiers combine outstanding audio performance with maximum reliability and operating security as well as being markedly lighter than equivalent power amplifiers.

Through the use of an optimized power supply with low dispersion toroidal transformers as well as of Class H technology (CL 800 Class AB) a large amount of headroom above the specified nominal output has been achieved along with a considerable reduction in weight and thermal leakage.

CL Series power amplifiers satisfy all the criteria for punishing ‘on the road’ use. They are reliably protected against overheating, overload and short‑circuits as well as high frequency and DC at the output. The ‘soft start’ function employs relays to insert a delay between switching on the device and the activation of the power outputs. A further circuit limits the current on power‑up, there‑by protecting the mains fuses. Dynacord amplifiers constantly monitor the input‑ versus the outputsignal by means of super‑fast audio processors which send ‑in case of non‑linear operation‑ control parameters to the limiters. The limiters are thus operating dynamically and do not affect the amplifiers dynamic capabilities as they control the input gain level. Thermal stability is provided by a 3‑stage fan with a very low noise level.

The inputs are electronically balanced and implemented on XLR connectors, whilst Direct Outs for looping the signal are also standard. Input routing permits the choice between Mono and Stereo modes. Mono bridged mode is also easy to realize thanks to the separate Bridged Out connectors and the Bridged Mode switch.
