PRODUCT OVERVIEW
HELVIA EVOCA 30H is a compact, lightweight and waterproof horn speaker, designed to provide high efficiency and high sound intelligibility with low distortion.
The built-in line transformer allows the horn to be connected to 70V and 100V constant voltage or low-impedance lines, and select the power through the rotary dial on the rear cover.
The horn can be easily mounted to any wall or ceiling by using the stainless- steel mounting bracket.
Thanks to the weatherproof treated plastic housing, the EVOCA 30H has an IP66 Ingress Protection standard, which make it suitable for 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.
Speaker Connection
EVOCA 30H horn speaker is equipped with a built-in line transformer with 5 power taps, to better adapt each speaker to the type of line (constant voltage @ 70V, 100V and low-impedance @ 8Ω), the power of the amplifier, and the number of speakers in the system.
When connect the horn to the line, pay attention to wire colors (red = positive; black = ground) and then adjust rotary selector on speaker back. Please refer to the following table.
| P osition | 70V | Power | 100V | Impedance |
|---|---|---|---|---|
| 1 | 15W | 30W | 3330 | |
| 2 | 7.5W | 15W | 6660 | |
| 3 | 3.75W | 7.5W | 1.3k0 | |
| 4 | 1.88W | 3.75W | 2.60 | |
| 5 | OFF | OFF | OFF | |
| 6 | 30W | 80 |
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 or 70V amplifier. If,for instance, you’re going to install 5pcs of EVOCA 30H speaker horn with 30W power (position 1) on a 100V line, you need an amplifierwith at least 5×30=150W RMS power. A good rule of thumb is to use an amplifier with 20% greater power; in this case, an amplifier with 180W or more.
