CONNECTOR CABLE
The following diagrams illustrate the wiring of the various types of sockets that can be
used with the DSP power amplifiers.
To connect the amplifier to the mixer, always make certain to use only signal cables
(screened cables made up of two wires plus a braid screen ), not power cables (speaker
cables, normally made up of two wires, usually with a greater cross-section): the use of
unscreened cables could in fact cause annoying buzzes and background noise. We
therefore always suggest the use of balanced cables for microphones and line units
whenever possible.
To connect the amplifier to the loudspeaker enclosures, always use only power
cables, not signal cables, as in the latter case in fact, the power from the amplifiers would
be partially dispersed because of the cable's smaller cross-section.
Take care of the connector cables. Always hold them by the connectors, avoiding
pulling the wire and avoid knots and twists when coiling them: this gives the advantage of
increasing their life and reliability. Check your cables periodically, making certain that they
are in good condition, that the connectors are correctly wired and contacts perfectly
efficient: in fact, many problems and setbacks (faulty contacts, ground hum, disturbance,
etc.) are due to the use of unsuitable of faulty cables.
