Dynacord CL 1200 User Manual

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.

Pins  2+/2-  of  the  CHANNEL A  SPEAKON  output,  which 

normally are not in use, are also connected to output B to 

ensure comfortable connection of 2-way speaker cabinets 

(e.g  in  Bi-Amping  Mode)  when  using  4-wire  Speakon 

cables.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

  With the BRIDGED-MODE switch being engaged, using the channel A input 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

  for audio signal feed is mandatory, since input B provides no function. While 

 

 

 

 

 

 

 

 

 

 

 

 

  the amplifi er of channel A operates as usual, the audio signal is internally 

 

 

 

 

 

 

 

 

 

 

 

 

  inverted and routed to the amplifi er of channel B. Both amps – A and B – now 

 

 

 

 

 

 

 

 

 

 

 

 

  work in push-pull operation to provide doubled output voltage at the 

 

 

 

  BRIDGED-OUT connector.

The regular output voltage of each amplifi er channel A / B is still present at the corresponding output 

connector CHANNEL A or CHANNEL B. However, using these signals is not recommendable because 

of the aforementioned phase inversion. Operating the power amp in Bridged Mode with loads of 2ohms 

connected is not allowable.

The ground-lift switch allows eliminating noise loops. If the power amplifi er is 

operated together with other equipment in a 19“ rack-shelf, setting the switch 

to its GROUNDED position is recommended. If the power amplifi er is operated

together with appliances with differing ground potentials, set the switch to its

UNGROUNDED position.

Under normal circumstances, the mains fuse only blows in case of fault.            

Replacing the fuse is only permissible when using a new fuse of the same         

type with identical amperage, voltage and blow characteristics. If the mains 

                                         fuse blows more often, please contact an authorized service centre. 

The high-performance mains cord supplied with your power amplifi er complies                                            

to applicable safety regulations, plus that its diameter corresponds to the power 

amp’s power output capacity. Make sure to use the supplied mains cord for connecting the power amp 

amp’s power output capacity. Make sure to use the supplied mains cord for connecting the power amp 

to the mains. Using mains cords with smaller diameters results in higher leakage and consequently re-

to the mains. Using mains cords with smaller diameters results in higher leakage and consequently re-

duced maximum power output capacity.

At 100V and 120V units the mains fuse is installed internally. This is fore safety reasons. In case of a 

blown mains fuse please contact a qualifi ed service personnel for servicing.

To prevent short-circuit and/or to protect your speaker systems from being damaged when connecting 

the cabinets, please make sure to mind the Low- and High channels’ specifi c pin-assignments!

If, for example, the subwoofer audio signal is used to feed a tweeter, it is more than likely that this will 

instantly destroy the HF-driver’s coil.
