Installation preparation
Cable lengths and profile
Once you have decided on where
the speakers are going to be
located, the first thing to do is to
lay the cabling from the amplifier
to the speaker.
Cable lengths and diameters
Revox speakers show a balanced
electrical impedance and phase
response, which means that they
represent an uncritical load for the
output amplifier and the speaker
cable. In order to keep the cabling
and high frequency losses to a
minimum, we recommend that
you use cables with the following
diameter and always to use 2-
core cables.
Up to 15 m:
Ø 1.50 mm
2
Up to 30 m: Ø 2.50 mm
2
Over 30 m: Ø 4.00 mm

Cable exit point
At least 150 mm should protrude
beyond the point where the cable
exits, to allow for the connections
.
Protecting the cable ends
The stripped ends of the cable will
be subject to attacks from the
weather and/or they are at risk of
oxidisation through contact with
the air. This is particularly the
case if the speakers are exposed
to salty air.
You can protect the stripped ends
with a silicon sealing material,
obtainable from any good,
specialist electronics retailer. If
your are going to apply sealing
material, you should only do this
once you have connected the
cable and the connecting strips
are firmly screwed into place.
Check the connections annually.
