  • Page 4: Precautions & Safety Notes

    Precautions & Safety Notes English • To reduce the risk of electric shock, disconnect the AC main power cord before installing audio cable. Reconnect the power cord only after making all signal connections. • Connect the unit only to a three-pole, three-wire grounding mains receptacle.
  • Page 5 Precautions & Safety Notes Deutsch (cont’d) • Um die Gefahr eines elektrischen Schlages auf ein Minimum zu reduzieren, den Lautsprecher Kontroller vom Stromnetz trennen, bevor ein Audiosignalkabel angeschlossen wird. Das Netzkabel erst nach Herstellung aller Signalverbindungen wieder einstecken. • Den Kontroller an eine geerdete dreipolige Schuko-Netzsteckdose anschließen.

  • Page 6: Description

    The DLC24 is intended to be the last device in the signal chain before the power amplifier(s). It is usually fed signal from a mixing console, although the source may be one of a number of devices such as a tape player, CD player, or equalizer.

  • Page 17: System Design, Preplanning, And Layout

    Software System Design, Preplanning, and Layout It is recommended that the system layout be planned in advance so that on-site system setup can be quick and effective. Loudspeakers should be placed into a tree structure consisting of Rooms, Arrays, and Subarrays. The organization of the system at this point will greatly impact how easily the system can be tuned and controlled later.

  • Page 18: System Example

    Software System Example This system example is provided to efficiently outline how to utilize the system structure of ADAM. It is provided in this manual as a teaching tool and does not exist as a tutorial in the software. It includes a center cluster of two speakers in a horizontal array along with one subwoofer and four front fill speakers mounted at the stage lip.
