PRODUCT OVERVIEW
HELVIA EVOCA 20P is high efficiency sound projectors designed to provide good
speech intelligibility and background music in a wide variation of
applications, and are perfect suited to be used in large 100V broadcast
systems such as shopping malls, stations, airports, etc.
It is fitted with a 6.5” broadband loudspeaker and the power is adjustable by
the integrated 100V line transformer with power taps for 20Watt, 10Watt and
5Watt at 100 Volt. The speaker can be easily mounted to any wall or ceiling by
using the stainless-steel mounting bracket.
Thanks to the weatherproof treated ABS housing with white weatherproof coated
aluminum grill, the speaker has an IP56 Ingress Protection standard, which
make it suitable for indoor as well as outdoor installations.

PRODUCT APPEARANCE
INSTALLATION
Read these instructions carefully before installing and using the product.
When the speaker is installed on ceilings or walls, check that the structure
is reliable and the speaker is firmly attached.
Do not use nails, adhesives or other unauthorized devices. Long-term use and
vibrations may cause it to fall easily.
Do not listen to sound at a very high level when you are changing the input
source (for example, from FM Tuner to CD player). Please be sure the power
amplifier is turned off or master volume is at lower level.
The installer is responsible of installation. Please pay attention to install
speakers according to local safety regulations.
When manage the speaker, be careful not to touch or load the front of the
speaker net with hard facing, otherwise it will deform the net.
5.1. Speaker Connection
EVOCA 20P sound projector is equipped with a built-in line transformer with 3
power taps, to better adapt each speaker to the type of line (constant voltage
@ 100V), the power of the amplifier, and the number of speakers in the
system.
When connect the speaker to the 100V line, pay attention to wire colors.
Please refer to the following table when connect them to the line.
Wire Color Black | EVOCA 20P |
---|---|
Red | Ground |
Green | 5W |
White | 10W |
20W |
UNDER-POWERING VS OVER-POWERING
Most speaker damages are caused by amplifiers with too little power (wattage).
Overdriven amplifiers clip output waveforms and send distortion to the
speakers.
Clipping is usually audible; it may vary from a harsh sound to a fuzzy or
unclear sound.
If you hear this condition at loud volume levels, turn down the amplifier
volume until the distortion is no longer present. Damages caused by operating
the speakers at distorted volume levels are no covered by warranty.
NOTE: Total number of speakers multiplied by tap value cannot exceed the
output power (in watts) of the 100V amplifier. If, for instance, you’re going
to install 5 EVOCA 20P sound projectors with 20W power (white wire) on a 100V
line, you need an amplifier with at least 5×20=100W RMS power. A good rule of
thumb is to use an amplifier with 20% greater power; in this case, an
amplifier with 120W or more.
