INTRODUCTION
The road series stage monitors have been designed to enhance the artist's performance and consequently
the success of the event. The road series employs a two-way configuration and a reduced enclosure size to
provide a low profile design without sacrificing power handling or sound quality.
The road is a 2-way powered stage monitor
that incorporates a 12R4 cone loudspeaker for
ROAD-12A, or 15R4 for ROAD-15A, for bass
reproduction. High frequencies are handled by an
M-75 compression driver with 1.5” exit, a 3”
titanium diaphragm and EFW voice coil. The 60° x
40° rotatable horn allows for high frequency
coverage options when the situation calls for it.
The versions "-NET" are compatible with DASnet.

The biamp lified system ( Low:550W +
High:220W) uses a 3th generation Class “D”
amplifier. With a 24-bit DSP providing FIR (Finite
Impulse Response) filters, unparalleled control over
critical signal parameters can be accomplished. It
allow two EQ presets: Monitor & Main.
The monitor’s low profile design, side mounted
handles, and strategically located skid plates allow
for ease of use onstage. Hidden connector plugs
and indicator LEDs offer an undistractive reference
for the artist and a clean stage appearance.

ON / OFF
A sound system should be switched on
sequentially. Switch on the self-powered units last
in your sound system (switch on the subwoofer
before the mid-high system). Switch on the sound
sources such as CD players or turntables, then the
mixer, then the processors, and finally the selfpowered unit. If you have several units, it is
recommended that you switch them on
sequentially one at a time.
Low mains voltage
If mains voltage falls below the shutdown
voltage for the unit, it will stop playing. When
acceptable levels are regained, the unit will switch
back on automatically.
The power supply allows the system to
function using two voltage ranges: from 90V to
128V, for 115V AC version, and from 180V to
256V, for 230V AC version.
Follow the inverse order when switching off,
turning self-powered units off before any other
element in the sound system.
Disconnect the device by removing the mains
connector from the mains socket. The mains
connector and mains socket must always be freely
accessible and never covered or blocked in any
way. The mains cable can be detached from the
device by disconnecting the Neutrik PowerCon
connector. Always disconnect the device by
removing the mains connector from the mains
socket before detaching the mains cable at the
Neutrik PowerCon connector.
IMPORTANT: Do not disconnect the unit when
it is playing music.
Ensure that the device is disconnected from
mains by observing that the ON LED is turned off.
Please note that the ON LED can stay on for
several seconds after the mains power has been
disconnected.
Overload indicator
This device has an indicator (LIMIT LED) that
lights when the signal is excessive.
The indicator should not be lit continuously.
This distorts the signal (quickly fatiguing your ears)
and may damage the speakers. Therefore, it is
recommended that you never work with this LED
on; at most it should blink only occasionally.
Therefore the current consumed by the first
range (90 to 128V) is double the second to
achieve the same acoustic power level.

DASnet
DASnet is the monitoring and control software
for DAS Audio powered sound systems and digital
signal processors.
Below you can see an image with the DASnet
control software interface window for an example
of road series device.
This software can only be used with "-NET"
versions, and you can find on our website both
your manual and more information about its use
with other equipment.
Overheating
This equipment does not normally overheat
during normal conditions of use. When overheating
occurs, the unit protects itself. You should then
find out why and if necessary contact an
authorised dealer for Technical Assistance.
Normally it is enough just to let the unit cool
down after you have corrected the problem so that
the system functions properly again.
Equalisation
The unit does not need extreme settings of
equalisation to produce quality sound. Avoid high
levels of gain on the equalisers. Gain values above
+3 dB on a console’s EQ are not recommended.

1- If using a mixer, use the balanced
output if available. Use a professional
mixer with a hotter output.
1- Turn mixer channel gains down.
Check that none of your signal
sources are distorting.
1- Turn down the mixer's output.
Hum or buzz when a mixer
is connected to the unit.
Hum or buzz when using lighting
controls in the same building.
The power on LED indicator(s) do(es)

1- The console probably has
un-balanced outputs. You may
be using an incorrect un-balanced
to balanced cable.
2- The mixer and the powered
speaker are not plugged into
the same mains outlet.
3- The audio signal cable is too
long or too close to an AC cable.
1- The audio signal cable is too
long or too close to the lighting cable.
2- On a sound system with threephase AC, the lighting equipment
and the UNIT are connected to
the same phase.
1 Bad or loose AC connection to
the UNIT or the mains outlet.
2 Faulty AC cable.
3 Blown Fuse.
1- Read the appendix of this manual
to make a correct un-balanced to
balanced cable.
2- Connect the mixer and the unit
to the same mains outlet.
3- Use a cable that is as short as
possible and/or move the audio
signal cable away from mains cables.
1- Move the audio signal cable away
from lighting cables. Try to find out
at what point the noise is leaking
into the system.
2- Connect the sound system to
a different phase than the lights.
You may need the help of an electrician
1- Check you connections.
2- Check the cables, connectors
and AC power with a suitable
mains tester.
3- Replace fuse on fuse holder with
one of the same type. If it blows again,
take the unit to a service centre.

specifications are subject to change without prior notice.
ACCESSORIES
Occasionally, you may need to use the road system in a more generic way, by incorporating a tripod
insert in one of its handles.
This can be combined with subwoofers, with the use of a TRD-6, or use on a standard tripod as the TRD-
2.
Follow the instructions in the Safety Precautions section to prevent system instability or overturning.
Do not hesitate to contact us if there are any
questions, and remember that DAS Audio, only
recommends these configurations by using
accessories TRD-2 and TRD-6.

ANNEX: Line connections: unbalanced and balanced
There are two basic ways to transport an audio signal with microphone or line level:
Unbalanced line: Utilising a two conductor cable, it transports the signal as the voltage between them.
Electromagnetic interference can get added to the signal as undesired noise. Connectors that carry
unbalanced signals have two pins, such as RCA (Phono) and ¼” (6.35mm, often referred to as jack) mono. 3
pin connector such as XLR (Cannon) may also carry unbalanced signals if one of the pins is unused.
Balanced line: Utilising a three conductor cable, one of them acts as a shield against electromagnetic
noise and is the ground conductor. The other two have the same voltage with respect to the ground
conductor but with opposite signs. The noise that cannot be rejected by the shield affects both signal
conductors in the same way. At the device’s input the two signals get summed with opposite sign, so that
noise is cancelled out while the programme signal doubles in level. Most professional audio devices use
balanced inputs and outputs. Connectors that can carry balanced signal have three pins, such as XLR
(Cannon) and ¼” (6.35mm) stereo.
The graphs that follow show the recommended connection with different types of connectors to balanced
processor or amplifier inputs. The connectors on the left-hand side come from a signal source, and the ones
on the right hand side go to the inputs of the processor or amplifier. Note that on the unbalanced connectors
on the left-hand side, two terminals are joined inside the connector. If hum occurs with balanced to balanced
connections, try disconnecting the sleeve (ground) on the input connector. Note that the illustrations show
what should be connected to what, but that pin locations on an actual XLR connector are different. Also, pin
2 hot is assumed on XLR connectors.
