In order to achieve the best acoustical performance, the HF3 IP Evo,
ideally has to be positioned near an angle/corner in the room.

Warning :

Check the mains voltage selector (N°1) position (115V/230V) and use the correct voltage for your country before connecting the 
mains plug. Changing the fuse : In the event of complete failure, first disconnect the powers cable from the mains, then check the 
mains fuse. When replacing the fuse, only use a fuse which is absolutely identical to the original one. If this does not solve the 
problem, contact your dealer.
• Only the subwoofer is to be connected to the mains supply. Never plug your speakers directly into the main power supply.
• Before proceeding with any connection, make sure that all your equipment is switched off.
• Before switching it on, please ensure that the "level" button (N°4) is on minimum.
• Your Waterfall Speakers are to be directly connected to the speaker output socket on your amplifier or A/VProcessor.
• Also ensure that the polarities are correct : + ( red ) and - ( black ).
• Do not expose this product to heat and humidity.

A) Functions & Set up of  HF3 IP’s Amplifier

Mains voltage selector (115V/230V)
Fuse
Main power switch (on - off)
Level : Volume adjustment of the integrated amplifier.
Phase : Alows you to adjust phase from 0 to 180°.
Freq : Adjustment of the frequency cut off, from 40 to 150Hz.

ted. When the Sub is activated this standby LED is off and the Logo LED 
lights up. Flashes in case of default.
On – Auto – Off : Recommended Setting should be : "Auto", so when 
not in use for a while, amplifier goes back into standby, if "On" position 
is used, this means the amplifier will continuously be on, and will not go 
into standby.

per octave or 12Db per octave is to be determined through listening 
and personal choice.

1 • Settings of your A/V amplifier :

In  the  Set  up  menu  of  your A/V  amplifer,  the  "small"  mode  on 
speakers should be selected. If your processor gives you a choice 
for the frequency cut off (crossover) in the menu, then choose :

- 80Hz

 for the channels using Iguasçu Evo or Victoria Evo.

- 120Hz

 for the channels using Hurricane Evo or Elora.

- 150Hz

 for the channels using Serio.

If your configuration is a mix of these products and if your Proces-
sor doesn’t allow you to choose variable  frequencies then choose 
120 Hz.

- Freq (N°6) on 150 Hz. The "24-12-LFE" (N°6) switch must be on 
the "LFE" position,
Phase  (N°5)  should  be  on  0°  in  most  of  the  cases. Adjust  the 
volume level (N°4) to your own choice.

The final audio result will be linked to the quality of 
your set up adjustments.

Finalise the complete set up (distance, test tone). Please refer to your A/V’s usuer manual or dealer if you need assistance.
