7. Do not connect this product to any equipment or accessories not foreseen.
For suspended installation, only use the dedicated anchoring points and do not try to hang
this product by using elements that are unsuitable or not specific for this purpose.
Also check the suitability of the support surface to which the product is anchored (wall,
ceiling, structure, etc.), and the components used for attachment (screw anchors, screws,
brackets not supplied by RCF etc.), which must guarantee the security of the system /
installation over time, also considering, for example, the mechanical vibrations normally
generated by transducers.
To prevent the risk of falling equipment, do not stack multiple units of this product unless
this possibility is specified in the user manual.
8. RCF S.p.A. strongly recommends this product is only installed by professional
qualified installers (or specialised firms) who can ensure correct installation
and certify it according to the regulations in force.
The entire audio system must comply with the current standards and
regulations regarding electrical systems.
9. Supports and trolleys
The equipment should be only used on trolleys or supports, where necessary, that are
recommended by the manufacturer. The equipment / support / trolley assembly must be
moved with extreme caution. Sudden stops, excessive pushing force and uneven floors may
cause the assembly to overturn.
10. Mechanical and electrical factors need to be considered when installing a professional
audio system (in addition to those which are strictly acoustic, such as sound pressure,
angles of coverage, frequency response, etc.).
11. Hearing loss
Exposure to high sound levels can cause permanent hearing loss. The acoustic pressure
level that leads to hearing loss is different from person to person and depends on the
duration of exposure. To prevent potentially dangerous exposure to high levels of acoustic
pressure, anyone who is exposed to these levels should use adequate protection devices.
When a transducer capable of producing high sound levels is being used, it is therefore
necessary to wear ear plugs or protective earphones.
See the technical specifications in loudspeaker instruction manuals to know their maximum
sound pressure levels.
12. To prevent the occurrence of noise, use screened cables only and avoid putting them
close to:
-Equipment that produces high-intensity electromagnetic fields
(for example, high power transformers)
-Mains cables
-Loudspeaker lines.
13. Situate this product far from any heat sources.
14. Never force the control elements (keys, knobs, etc. ).
15. Do not use solvents, alcohol, benzene or other volatile substances for cleaning the
external parts of this product. Use a dry cloth.

RCF S.P.A. THANKS YOU FOR PURCHASING THIS PRODUCT, WHICH HAS BEEN
DESIGNED TO GUARANTEE RELIABILITY AND HIGH PERFORMANCES.
DESCRIPTION
This device can be installed into a 19” rack cabinet (1 unit) with 4 screws, thanks to its
rack ears.
RDNET is a proprietary protocol of a network that allows to connect up to 256
compatible audio devices (i.e. professional RCF loudspeakers mod.TTL55-A, TTL33-A,
TTL31-A, etc.) to a computer (PC with Microsoft Windows® o. s.) to check and remote
control them.
RDNET CONTROL 8 unit routes all data between the PC and audio devices.
The RDNET system allows to monitor every device, checking voltages and currents,
temperatures, audio signal RMS values, cooling fans, etc. .
The PC cyclically requires the RDNET CONTROL 8 unit the operating state of audio
devices that make up the communication network. All data are collected by the central
unit that performs a sequential scan of all audio devices.
Digital address allocation is automatic.
Information relating to the functioning of all audio devices is acquired in real-time,
feature that allows a network global view.
It is possible to check each single audio device and edit its parameters (e.g. output level,
mute, equalization, delay, etc.) by using the PC software.
The audio device overall configuration can be saved as file in the PC and later reloaded.
It is possible to synchronize all parameter values of the RDNET CONTROL 8 unit to the
ones of the PC software preset.
The link between the PC and the RDNET CONTROL 8 unit can be made through either
the USB port or ETHERNET, the latter is useful when the PC is far or it is necessary to link
the RDNET CONTROL 8 unit to an ETHERNET net already wired.
USB link shall be at least version 1.1 (2.0 is OK) and
can be used when the PC is close to the central unit (a
few metres).
The RDNET CONTROL 8 unit can manage up to 8
subnets. Up to 32 audio devices can be connected
to each subnet (8 subnets x 32 = total 256 audio
devices).

Delay: audio signal delay setting.
USE EXAMPLE
It is possible to get common settings for two front line-arrays (made of loudspeakers) of a
stage, by using MASTER algorithms, for instance:
MASTER: common settings for all loudspeakers (both left and right channels)
LEFT: common settings for all left loudspeakers only
RIGHT: common settings for all right loudspeakers only
FAR: common settings for all far-field loudspeakers only
NEAR: common settings for all near-field loudspeakers only.
Click View of a CURVE algorithm to see its respective setting window:
The CURVE algorithm can be useful when using subwoofers (loudspeakers designed for
very low frequencies), placed on the ground at the centre under the stage, to improve
their efficiency by creating a ‘virtual curve’ of subwoofer positions.

20
ENGLISH
The 3 parameters (to be set) in the window on the right:
Group: quantity of subwoofers grouped at the same position
Distance: distance (in metres) between a subwoofer group axis and those adjacent
Radius: curve radius (in metres).
In each line (corresponding to an object):
Loc.Delay: audio signal delay value (indicated in the equivalent distance in metres, max.
20 metres) that depends on the 3 parameter settings
Inc.Delay: audio signal total delay (the sum of all delays, considering also all algorithms
upstream of the selected one).
About the buttons up, dw, del, send, obj select, please refer to the previous MASTER
algorithm.
Click View of a TILT algorithm to see its respective setting window:
The TILT algorithm can be useful when using subwoofers in a suspended cluster to get a
better near-field coverage, by creating a sort of virtual vertical tilt of subwoofers.
The 2 parameters (to be set) in the window on the right:
Angle: vertical tilt angle (degrees)
Distance: distance (in metres) between a subwoofer axis and those adjacent.
In each line (corresponding to an object):
Loc.Delay: audio signal delay value (indicated in the equivalent distance in metres, max.
20 metres) that depends on the 2 parameter settings
Inc.Delay: audio signal total delay (the sum of all delays, considering also all algorithms
upstream of the selected one).
About the buttons up, dw, del, send, obj select, please refer to the previous MASTER
algorithm.
