7.1. Audio input

Connector for attaching an external audio signal is located in the bottom part of front panel. When applying signal to this input program announcement is activated.

Through + and – buttons can be controlled the output volume, while concurrent pressing of both buttons mutes the output completely.

The five green LEDs located above buttons acts as indicator of adjusted sound volume.

7.2. Power audio outputs

The power amplifier has two independent channels A and B with common input. The nominal power output is valid for 4-Ω load impedance. The outputs together with power supply and RS485 interface are wired in X1 connector (see chapter 4, Fig.4).

7.2.1 Rules for connecting loudspeakers

The amplifier outputs can be connected to a different number of loudspeakers.

Rules for connecting: Ensure the total minimum impedance 4 Ω for each channel by combination

of serial and parallel wiring of loudspeakers. Overall power of combination of speakers must be equal or greater than

amplifier maximum output power. When needed, whichever loudspeaker from combination can be substituted

by resistor with the same impedance (resistance) and wattage. Keep the loudspeaker polarity (to avoid playing in the antiphase).

7.2.2 Wiring examples

Number of speakers and layout of them must be determined by project designer. In next wiring examples, with accordance to need of spatial arrangement, any speaker can be substituted by resistor with the same impedance and wattage.

8.2. Factory setting

Factory setting can be restored through RESTORE button. To press the button use a tool with diameter max. 1.5 mm (e.g. match, or ballpoint refill). To restore the factory setting press and hold the RESTORE button while unit start-up. The PON LED first lights ON and after about 5 sec starts to blink. Release the button after beginning of PON LED blinking.

After restoring of factory setting unit goes to operation and the PON LED starts to light permanently. Unit factory setting

9.2. Installation rules

PE terminal of power supply connector must be connected with local installation earthing terminal.

Minimum cross-section of supplying conductors must be at least 0.5 mm2.

Communication line wires must be shielded. Shielding must be connected either to metal connector caps or to PE terminal.

It is very important to ensure that ambient temperature does not exceed the allowed limits. Together with it must be ensured that heat-radiating equipment located nearby does not cause exceeding of these maximum temperatures.
