VI1x6
Six room speaker-stereo interface
Installation instructions
Warning
: To be installed and/or used in accordance with appropriate local electrical
codes and regulations.
Description:
The Knöll VI1x6 six-channel speaker-stereo interfaces can safely
power two to six rooms of stereo speakers from one stereo amplifier or receiver.
Speakers can be similar or dissimilar and each will sound their best.
The VI1x6 stereo interface is also used to set individual volumes in each room.
Parallel or series speaker wiring is acceptable. Maximum power input is 150 watts
per channel. The VI1x6 features an incredible "ultra" music quality frequency
response of DC to 500,000 Hz +/-0.1dB at all power levels up to 200 watts due to
its transformer-free
topology.
Depending on the quantity and type of speakers chosen, the VI1x6 may offer the
amplifier impedance as low as 4 ohms,
so we suggest that your amplifier (or receiver) be rated for
4-ohm (or lower) operation. The VI1x6 is usually but does not have to be stacked
with the stereo equipment and does not need a power supply.
Basic System Layout and Pre-Wiring
: The VI1x6 is usually stacked with the
stereo equipment. It may get warm or a bit hot, so it needs ventilation for maximum
power and longest life. Don’t cover or block the vent holes. Take care to mount it
away from anything that can be damaged by heat.
From each speaker run a
fire rated
two-conductor speaker wire, ideally 16 gauge or
larger for runs up to 33’ (10m) and 14 gauge or larger for longer runs to the VI1x6
stereo interface (or volume control then to the interface). To save time and money,
many installers run a four-conductor speaker wire from the volume control to the
stereo interface. If there is more than one pair of speakers connected to a single
VI1x6 room connection, wire the speakers in series or parallel whichever makes the
impedance closest to 4 or 8 ohms.
Do not attempt
to make the final combined
speaker impedance less than 4 ohms.
