CABLING
The mains cord is supplied with your PowerMate. The quality of all other cables is left to your responsibility. Care- fully chosen high quality cables are the best precaution to prevent problems from occurring during the later ope- ration. In the following we would like to provide you with some recommendations for the trouble-free operation of your setup.
SPEAKER CABLES
Our experience as a manufacturer of loudspeaker systems has taught us that flexible cables with a rubber jacket and a diameter of 2.5mm2 per conductor, used in combination with SPEAKON plugs and sockets, are the best choice to guarantee the optimal connection of loudspeaker systems. The connection of the SPEAKON plugs
to the corresponding connectors on the PowerMate’s rear panel has to be in accordance to the corresponding diagram below. We recommend the use 4-wire cables where also the pins 2+ and 2- are connected through. This provides you with the possibility to use these cables in an active 2-way system configuration, as well. DYNACORD speaker cables with SPEAKON connectors and all other cables, plugs, and sockets are available at your professional audio dealer.
LF-CABLES – BALANCED OR UNBALANCED?
For LF-cabling – all the low current wiring – your best choice are balanced cables (2 signal conductors + ground shielding) with XLR-type connectors or stereo phone jacks and plugs. The cables should be step proof, shielded, and never longer than absolutely necessary. Too many too long cables mostly lead to confusion and generate unnecessary problems. Of course, you can also connect unbalanced cables with monaural phone plugs to the PowerMate’s in- and outputs and because of its superb grounding managing system, in most cases no interfe- rence will occur. Still, there is a minimal risk that problems could arise. Generally spoken, if you have the choice, balanced LF-cables are always the better solution and they should be preferred. Today’s modern audio equip- ment – like amplifiers, equalizers, FX units, mixing consoles, and even some keyboards – offers balanced in- and outputs. In a balanced signal path, the cable screen provides a gapless connection of all metal parts, offering efficient shielding against the induction of external noise. The balanced cabling in conjunction with the common- mode rejection of the PowerMate’s input stage effectively eliminates even existing artifacts of interference. All inputs of the PowerMate provide balanced audio connections and high common-mode rejection. The mixing stage outputs – AUX, MAIN, etc. – are laid out in GND-SENSING technology – a special, impedance-balanced pin assi- gnment of the output jacks, offering all advantages of the balanced signal transmission, but lets you also connect monaural phone plugs, without a problem. Nevertheless – as mentioned above – when longer cables are invol- ved, using stereo phone plugs and balanced cables are the better alternative. The diagrams below show the pin assignments of plugs and cables like they can be used with the PowerMate.
