Voxnet 219 Safety

Welcome
Voxnet is an Ethernet-based multiuser /
multiroom audio system developed by
Revox with a new, unique operating
philosophy and an impressive audio
quality. This is characterised by
streaming at CD level quality and with
the smallest latency periods, so that
music can be heard in its purest form,
with practically no delay, in each room.
The hardware audiophile core of the
system is represented by the modular
Voxnet 219 stereo amplifier. Its powerful
2 x 50 watt outputs can even provide
enough power to drive column speakers.
The integrated DSP (Digital Signal
Processor) allows adjustments to be
made to handle all Revox speakers. You
just have to select the corresponding
Revox speaker in the Configurator list
and then define the positioning and/or
the installation method. This is all you
need to achieve the optimum in sound
quality for a clean reproduction. In
addition, a professional 8 band equaliser
(parameters: Q, Fc, Gain) allows you to
balance the system to meet your
personal preferences.
Traditional music sources, both
analogue and digital, can be connected
through the optional I/O module.
Needless to say, this is possible in HD
quality with data rates of up to 192
kHz/24 bit. In order to deliver even more
comfort, all inputs are equipped with
freely definable detector switching to
permit automatic switch-on, for example,
as soon as an audio signal is detected on
the corresponding input.
One of the Voxnet system's powerful
tools is the range of trigger options
available, that make it possible to control
the system in many ways externally,
using, for example, the five input
triggers: Infrared (RC5), Audio, Room,
Source and Voltage (IN). In the opposite
direction, other devices can be
controlled and/or addressed through the
output trigger (OUT / 12 VDC).
As well as the triggers, the Voxnet
system also offers proxy servers that can
be used to control devices outside the
Voxnet world, using IP commands.
Revox can supply corresponding 1 U
height shelves to accommodate 2 Voxnet
219s, for quick and secure installation in
a 19" rack (Article no.: 1.563.090.00). A
single bracket (Article no.: 1.563.091.00)
is also available for wall-mounting.
This product innovation from Revox
stands out as a true system for life,
thanks to its legendary robustness and
longevity, which the brand is known for
throughout the world.

Commissioning
Please check the unit and accessories
after unpacking, to ensure that
everything is there and that there are no
signs of transit damage. Read the User
manual through carefully before starting
to use the unit. Keep the manual for later
reference. A unit that shows signs of
mechanical damage or which has had
liquid in it may not be connected to the
mains supply.
Only use the mains cable supplied. If a
different cable has to be used, it must
comply with the values 10A/125V. Any
alternative power cable used must have
corresponding certification
(UL/CSA/VDE).
The unit’s power supply and connections
values (mains voltage, frequency) must
be checked before connecting it to the
mains.
Use of switch-on current limiter
In the case of the installation of more
than
4 Voxnet 219s per secured 16A
circuit, Revox recommends the use of a
switch-on current limiter.
This provides effective protection
against a mains circuit breaker being
tripped during switch-on following a
power outage or an overnight shutdown.

General safety instructions
Please follow the instructions in the
User manual supplied.
Do not position the unit close to strong
heat sources or in direct sunlight.
Please take note of the following, if the
Multiroom amplifier is to be installed in
a cabinet or closed shelves: Allow at
least 5 cm of free space around the
device, so that the air can circulate
freely and so that there is no build up
of heat. Do not cover openings on the
back or front walls of the unit.
It must be ensured that the correction
functioning of the unit's ventilation
openings is not affected by being
covered, e.g. by curtains, newspapers,
table cloths, or similar.
This unit conforms to protection class
2. This means that with this unit, the
ground cable is not connected to the
housing, in order to effectively
eliminate sound-damaging groundloops. With these Multiroom amplifiers
however, Revox uses the ground cable
for the reduction of noise fields. For
this reason, both the supplied cable
and the connection panel are fitted
with a ground cable.
Unplug the unit if you are going to be
absent for a longer period of time.
Unplug the unit from the mains during
storms. Voltage peaks through the
mains power supply caused by
lightning strikes can damage the unit.
There must be easy access to the
power plug so that the unit can be
unplugged at all times.
Lay the power cable such that it
cannot be damaged. The power cable
should not have kinks or by laid over
sharp edges. It should not be walked
on or be exposed to any chemicals.
The last point is valid for the whole
unit. A power cable with damaged
insulation can lead to electric shocks
and represents a fire hazard.
Never pull on the cable when plugging
the unit in or out. Always hold the plug.
Liquids, flammable or other objects
should not be inserted in the unit’s
openings as this can lead to faults, fire
or an electrical shock.
Do not expose the device to splash
water or high levels of humidity. Do
not stand containers filled with liquid,
e.g. flower vases, on the device.
It is only designed for operation in
temperate, non-tropical climates.
Take note of and follow the safety advice
on the following pages.

Rack installation
The Voxnet 219 is designed for
installation in a 19" rack. A shelf / tray
(Revox Article no.: 1.563.090.00) is
available as an accessory, which can
take two Voxnet amplifiers. The height of
the shelf is 1 U.
The tray can be built into the rack with
and without Voxnet amplifiers. Both
options are possible depending on the
installation environment.
The Voxnet 219 has a recess to the left
and right of the front edge which the
metal lugs of the tray (upper picture / )
fit into. Locate the amplifier, lined up
with the right or the left of the tray and
push it backwards until it reaches the
back wall of the tray. The amplifier is
now fixed in place horizontally at the
front and vertically.
Now turn your attention to the rear of the
tray. Two knurled thumb screws are
provided with each amplifier for fixing it
into place (lower picture / ). Screw the
amplifier into place with these until they
are hand-tight.
This completes the installation of the
Voxnet 219.

Environmental conditions in the rack
In the case of a rack installation, you
must ensure that the inside temperature
of the rack does not exceed +40°C /
+104°F. If necessary, the rack must be
actively cooled using a fan.
The Voxnet amplifier itself is fitted with
an active fan control and controls its
own inner temperature. Cool air is
sucked in at the front of the amplifier,
drawn through the unit and blown out of
the slots at the back. For this reason,
cool air must be able to get to the front
of the amplifier to be drawn in, even if
the rack door is closed. Multiple trays
can be mounted underneath each other
in the rack, without having to leave any
gaps between them.
Stack of 8 Voxnet 219s
Use of switch-on current limiter
In the case of the installation of more
than
4 Voxnet 219s per secured 16A
circuit, Revox recommends the use of a
switch-on current limiter.
This provides effective protection
against a mains circuit breaker being
tripped during switch-on following a
power outage or an overnight shutdown.
