Tips
• Again in this case, if an overall output power exceeding that of a
500W
amplifier (the largest in the
Paso
range) is required, it is possible to use
more than one amplifier, as described in the tips for section
5.1
.
• It is not necessary to cable the terminals
M.
(
18
) and (
34
) for the slaves with zones in which background music is not envisaged.
• Generally speaking, background music is distributed at a low level, requiring less power than for calls. In these cases, to make the system cheaper,
it is possible to use an amplifier for music with a rated output of half that of the speech amplifier, and to use the 70 V output instead of 100 V for
the speech amplifier.
• If the music amplifier has its own volume control, it is possible to connect the music source directly to the amplifier input rather than to the
MUSIC
IN
input (
25
), saving one cable.
5.3 Systems with dedicated amplification for each zone
This type of system is used to drive high-power zones that require one amplifier each. Switching of the input signal of the amplifiers rather than of the
power output is therefore used. The following diagram also shows the cabling of the signal for background music. As can be seen, the diagram is very
similar to that in section 5.2, with the difference, however, that the inputs of the amplifiers are connected to the single zone outputs, and the lines of
the speaker units are connected to the relevant power outputs of the amplifiers.
Like the configuration of section 5.2, this configuration
enables music to be maintained in the zones not affected by the call
.
For the sizing and settings of the system in Figure 5.3.
