I can?t even remember how many times we?ve been asked about a self-powered ceiling speaker with technical specifications greater than those 1 or 2 W ceiling speakers (the most common models in the market). We almost always answer people in the trade that the IC 6 Pro A is perfectly indicated, but they usually answer that they do not need remote control, but rather a simple self-powered ceiling speaker.Competitive advantages of the IC 6 Pro A in comparison with 100 V audio systems
We wanted to publish this post because many people in the trade do not really know the IC 6 Pro A ceiling speakers. Actually, they don?t know that it can be used as a simple self-powered speaker, without any kind of control. It is also a cost competitive solution, becoming a very relevant, good value solution for many installations. Furthermore, using IC 6 Pro A provides great advantages in comparison with 100 V conventional audio systems:Independence between ceiling speakers, with the 100 V audio systems, a failure of the amplifier would have serious consequences on the whole installation. This cannot happen with IC 6 Pro A and if one ceiling speaker would fail, it will never affect the other ceiling speakers.Better audio quality. Thanks to the class D amplifier, audio quality is better than what you can expect from a 100 V Line installation.
Steps to follow in order to use IC 6 Pro A in simple self-powered mode.Steps to follow to configure a simple, self-powered mode with IC 6 Pro A
In the first part of this post, we have been dealing with the advantages of IC 6 Pro A for this kind of installation. Now lets take a look at the connections of the speaker and learn how to use it.1. 24 V input
2. Balanced signal input
First of all, there is a 24 V input: we have to connect a 24 V CC power supply. If there is more than a ceiling speaker in the zone/installation, we can perfectly use a power supply with more Watts and connect all the speakers of the zones, taking into account ceiling speakers requirements (2 A).
The balanced signal input (which comes from a mixer or pre-amplifier) is used to connect all the speakers in parallel.
This is a high impedance input, so signal loss is insignificant.3. RS 485/DMX control input
Forget the RS 485/DMX control input.
You don?t have to connect this input because there is no remote control.4. 0-10 V analog control input
The + terminal must be connected through a cable to the + terminal in DC 24V block.
This indicates to the micro-controller that amplifier volume has to be at maximum value.
Regarding the dipswitches, their position doesn?t matter because the 0-10 V input has been previously shortcut.
It doesn?t change anything in the configuration of the speakers.This is the diagram for audio installation:
