Avoid setting the top cut-off frequency above 130 Hz. Otherwise
the location of the subwoofer in the room will be clearly audible
because its performance in this range is perfect. Human ear
cannot locate lower frequencies.

OLTAGE
– Mains Voltage Switch (7)
The veto subwoofer
can be operated in all countries and is good
both for 110/115 and 220/230 V. Before the first operation, please
make sure that voltage setting is correct for your electricity mains.
BEWARE: Switching can be performed only when the power cable
is disconnected.
If the switch is in "115 V" position and the device is connected to
230 V, irreparable damages will occur!

NPUT
– Mains Connection (6)
Insert the supplied power cable into this connector.
Never use other power cables – it is possible that they do not
carry enough current. This can cause malfunctions leading to fire.
Before connecting the cable, please make sure that the voltage
switch is in the correct position (see also AC

Main Fuse (2)
In the mains socket there is a main fuse as well as a spare fuse.
They may only be replaced with identical fuses! Use of different
fuses voids warranty.

ERALINK
– 7-pole Amplifier Connection (for
Bang&Olufsen equipment) (3)
If you have Bang&Olufsen equipment, it can be connected to the
veto subwoofer with the Ceralink cable. Ceralink carries musical
signal and switching on/off operation commands.

HASE
– Phase Switch (8)
For most natural bass reproduction all speakers in the system
should oscillate in the same phase. This can be heard with a great
distinction especially in low frequency range because it is low
frequency that originates from fewer cone excursions
(specification measured in Hertz (Hz) shows the amount of
oscillations per second).
Low frequencies are reproduced mainly by the veto subwoofer.
However, the other speakers also play some sounds of this range.
If cones oscillate in different phases, these frequencies may not be
audible anymore.
For optimum syntonizing
of the veto subwoofer and the other
speakers, it is also necessary to adjust the direction of cone
oscillations. First, leave the switch in its normal position and test
the system with music tracks containing powerful low-frequency
impulses. Move the switch to another position and check, which
case provides the best performance.
If the switch is set correctly, reproduction will be homogeneous
and rounded. If the sounding is high or inharmonious, you can
change either place or volume. This adjustment should be made
once before the first operation. However, after veto is moved to a
new place, you may need to readjust.

NPUTS
– Amplifier Connection with a Cinch Cable (4)
Connect the veto subwoofer to the subwoofer output of your
amplifier with a cinch cable. This line transfers the signal, as well
as veto automatic switch on/off commands.
If you have a Bang & Olufsen amplifier, we recommend
connecting it through the CERALINK line (see above: CERALINK).
Troubleshooting
Ceratec has laid the foundation for disturbance-free and
maintenance-free operation in both construction and
choice of materials. However under certain circumstances
the following disturbances that are not caused by the
speaker can occur
.
•
Humming noise. This is usually caused by electricity
mains, and in most cases it can be easily repaired.
Wait till veto switches on, and then unplug all
devices of the stereo or home cinema system from
the net. If one of these devices is responsible for the
interference, please insert its power cable plug into
the socket in the opposite direction. If necessary, do
the same with the veto power cable.
•
The subwoofer can switch on automatically when
there is no musical signal. The reason is parasitic
interferences of the acoustic cable (Cinch or
C
ERALINK
).
Therefore use high-quality cables only.
