Presets Although some parameters such as number of units, gain, LPF and HPF can be selected by acting on the switches of the amplifiers, it is more comfortable and more complete, to make the changes of the presets by DASnet , as we can observe in some examples below.

INSTALLATION AND ACCESSORIES In this section we will see how to stack the SF-20A (LT / RT) on the SF-1521A. In addition, with the help of two metal plates, JP-20, included in each SF-20A (LT / RT), we will see how to angle the SF-20A (LT / RT) according to the desired coverage, with examples .
Page 17
Now, we will screw each JP-20 on the corresponding side, considering the angle assigned to the box, but do not tighten completely. Allowing you to place easily the SF-20A (LT/RT) on SF-1521A. Once the SF-20A (LT/RT) is located above of SF-1521A, you should tighten the screws into the appropriate holes at the desired angle.
Page 18
Let's look at some examples of these coverages for the system SF-Monitor (right or left), according to the selected angles. If we had only one SF-20A (LT/RT), we would have the following coverage for the recommended angle: 13º. Note: The red dots in the JP-20 indicate the proper position for the screws in each case. ANG.
ANNEX I : Line connections: unbalanced and balanced There are two basic ways to transport an audio signal with microphone or line level: Unbalanced line: Utilising a two conductor cable, it transports the signal as the voltage between them. Electromagnetic interference can get added to the signal as undesired noise. Connectors that carry unbalanced signals have two pins, such as RCA (Phono) and ¼”...
ANNEX II : DASnet cables With each system, cabling and patch panels are provided. It is very important to use the system with the intended cables to prevent electromagnetic interferences between the analog audio signal, the DASnet data and the power. Be sure to check the specifications provided by the cable manufacturer.
