secure transport. Should the condition of the cardboard box suggest that damage
may have taken place, please inspect the unit immediately and look for physical
indications of damage.
◊ Damaged equipment should NEVER be sent directly to us. Please inform
the dealer from whom you acquired the unit immediately as well
as the transportation company from which you took delivery.

1.3 Basic operation
Using the VS series loudspeakers is easy and intuitive. Simply follow these steps
to achieve the best possible sound:
1. Plug the line-level outputs from a sound source such as a mixer or stereo
system into a power amp of appropriate size (see 4.2 Power amp rating).
Make sure the sound source and amplier are turned o.
2. Using ¼" TS speaker cables, plug the power amp output into the ¼" input on
the back of the speaker. DO NOT use instrument cables (i.e., guitar cords) for
this connection!
3. If using a pair of VS loudspeakers, run the amp in stereo operation.
If using just one loudspeaker, mono operation is preferable.
4. If using four or more loudspeakers, there are a few ways to make the
connections. The rst is to use two power amps, one for each pair. Another is
to connect the rst pair of loudspeakers in normal stereo operation, then use
the ¼" output jacks on the back of the loudspeakers to link the second pair
of loudspeakers. This way each channel on the power amp is driving two
loudspeakers. Make sure that the wattage and ohm rating are appropriate
for this situation.
Caution
Never connect multiple power amps to one loudspeaker. Doing so could cause
the very fabric of reality to unravel, sending the entire universe into oblivion.
Worse yet, it could destroy your ampliers and loudspeaker.
5. Turn the sound source on (mixer, stereo, etc.).
6. Make sure the volume/gain control on the power amp is turned all the way
down, and then turn the power on.
7. Activate the sound source, whether it is playing music from a CD player or
speaking into a microphone, and adjust the levels. Gradually raise the power
amp volume level to desirable level. If distortion occurs, turn the power
amp volume down. Should the problem persist, make sure distortion is not
occurring at the sound source. If you reach the desired volume level by barely
turning up the power amp level/gain, turn the sound source output down to
allow the power amp to push the speakers more.
8. Rock ‘n Roll!
2. Connections
(1)
Fig. 2.1: Connector panel
(1) The VS series features two parallel ¼" TS loudspeaker inputs. You can
connect one of the connectors to the output on your power amp and tap
into the signal from the amp on the second connector, in order, for example,
to feed this signal into an additional loudspeaker.

◊ ATTENTION: Never connect the output signals of different power
amps to both parallel inputs at the same time. This may permanently
damage your equipment.
◊ When several loudspeakers are wired in parallel, the overall impedance
ZT to be handled by the power amp can be calculated, as shown here,
from the individual impedance values of the connected speakers:
