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 input- vs output- signal by means of superfast audio proces­sors which send –in case 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-stage fan 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 a Ground-Lift switch 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.
