[10] R – L SPEAKERS
Speaker connection
Always use a cable of a
sufficient diameter for
connecting your speakers to the
M219.
RE
V
OX recommends:
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
2
We recommend not to use
cables longer than 50, due to
the unavoidable loss of HiFi
reproduction.
Each individual speaker must
have an impedance of 4
Ω or
higher. You must ensure that all
cable strands are within the
screwable Phoenix connector
and that none of them come
into contact with any adjacent
connectors or the M219
housing.
You will only be assured of a
perfect stage-quality
reproduction if you ensure
correct polarity when
connecting. A wrong polarity will
not cause any damage to the
speaker or to the M219, but it
can result in imprecise and
diffused reproduction that is
weak in the base ranges.
[11] FUSE
Fuse
Always power the unit down
before replacing the fuse.
When replacing the fuse, always
one of the same type as shown
on the M219 rating label.
Other fuse types with
different power, voltage or
operational characteristics
can endanger your life and
damage the unit.
The fuse holder can be
removed by pushing it in slightly
and then turning it in the
direction of the arrow.
[12] AC-POWER
Power connection
Only use the
RE
V
OX power
cable supplied. You must also
ensure that the power supply
used delivers the voltage as
shown on the M219 rating label
(240V). If required, the M219
can be modified to work with
other voltages. This
modification should only be
carried out by an authorised
specialist.
