Switch on-off

A sound system should be switched on
sequentially. Switch on the self-powered unit last in
your sound system. Switch on the sound sources
such as CD players or turntables, then the mixer,
then the processors, and finally the self-powered
unit. If you have several units, it is recommended
that you switch them on sequentially one at a time.

Follow the inverse order when switching off,
turning self-powered units off before any other
element in the sound system.

Mute all signal sources before switching the
unit on or off.

Limit indicators

It is recommended that the red LIMIT LED
indicators are not lit continuously; at most it should
blink only occasionally.

If you wish to have a visual indication at the
mix position of whether the LIMIT LEDs are
lighting, during equipment set-up, closely observe
what mixer VUmeter level corresponds to the level
that lights the enclosure's LIMIT LEDs. That level
that should not be exceeded during the event.

Overheating

Due to their high efficiency, the Stage Monitor
series amplifiers generate very little residual heat
and therefore do not need a fan for cooling. In
normal use, the amplifier panel will be warm to the
touch.

If the unit stops playing (or just the mid-high or
the bass sections), the amplifier's overheating
protection may be activated to protect the
components from thermal damage. Overheating
may be due to insufficient cooling, or to very
aggressive use in extremely hot conditions. Do not
use the unit in proximity to high power lights. Once
the amplifier cools down, it switches back on
automatically. If the unit should shut down again,
try reducing the volume a notch to avoid
overheating.

Equalization

Side changing of the amplifier

The units do not need extreme settings of
equalisation to produce quality sound. Avoid high
levels of gain on the equalisers. Gain values above
+6 dB on a console's EQ are not recommended.

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.

Warning

This manual contains needed information for
flying DAS Audio systems,
description of the elements and safety
precautions. To perform any operations related to
flying the system, read the present document first,
and act on the warnings and advice given. The
goal is to the allow the user to become familiar
with the mechanical elements required to fly the
acoustic system, as well as the safety measures to
be taken during set-up and teardown.

Only experienced installers with adequate
knowledge of the equipment and local safety
regulations should fly speaker boxes. It is the
user's responsibility to ensure that the systems to
be flown (including flying accessories) comply with
state and local regulations.

The working load limits in this manual are the
results of tests by independent laboratories. It is
the user's responsibility to stay within safe limits. It
is the user's responsibility to follow and comply
with safety factors, resistance values, periodical
supervisions and warnings given in this manual.
Product improvement by means of research and
development is ongoing at D.A.S. Specifications
are subject to change without notice.

To this date, there is no international standard
regarding the flying of acoustic systems. However,
it is common practice to apply 5:1 safety factors
for enclosures and static elements. For slings and
elements exposed to material fatigue due to
friction and load variation the following ratios must
be met; 5:1 for steel cable slings, 4:1 for steel
chain slings and 7:1 polyester slings. Thus, an
element with a breaking load limit of 1000 kg may
be statically loaded with 200 kg (5:1 safety factor)
and dynamically loaded with 142 Kg (7:1 safety
factor).

stage monitors

Introduction

are the models in the

SML stage monitors series

that feature the necessary hardware to be flown.
As has been said above, are versatile
multipurpose cabinets which can also be used as
a low profile floor monitor.

cabinets feature 6 “L” shaped internal

SML

metal hardware pieces, each one including 2 M10
nuts, thus providing a total of 12 rigging points.

Rigging with AX-TRUSS

AX-TRUSS

The rigging hardware has been
designed to fly the cabinets from structure trusses
of 50mm diameter (2 in diameter). The
base must be fixed to the upper rear corner of the
box by means of two M10 screws. The screw
needed to attach the base to the upper
side of the box is the same that comes with the
box on that position. The screw to be inserted on
the rear side of the box is a special one that is
provided with the accessory.

the holes in the base.

When flying a system, the working load must
be lower than the resistance of each individual
flying point in the enclosure, as well as each box.
Hanging hardware should be regularly inspected
and suspect units replaced if in doubt. This is
important to avoid injury and absolutely no risks
should be taken in this respect. It is highly
recommended that you implement an inspection
and maintenance program on flying elements,
including reports to be filled out by the personnel
that will carry out the inspections. Local
regulations may exist that, in case of accident,
may require you to present evidence of inspection
reports and corrective actions after defects were
found.

The next step will be to secure the fixing
hardware part to the truss. In order to do so, the
nut and the wing nut must be tightened. Make
sure that the fixing hardware has been secured
tightly to the truss, and that it is not able to swing.
This way both parts of the rigging hardware will be
fixed: one to the truss and the other one to the
box.

Note: Maximum load capacity for is

Rigging with eyebolts (kit )ANL-2

The Allen-head screws must be removed and
replaced by M10 eyebolts on one side of the
enclosure. Each rigging point has 200 Kg (440 lb)
working load limit. Then choose the slings or
chains of required load resistance and length,
bearing in mind that the length difference between
the front and back slings or chains will determine
the vertical orientation. Alternatively, vertical
orientation can be achieved by using the back
bottom eyebolt points on the units that feature
them.

The set is an optional set of eyebolts

ANL-2

and carabiners.

In the following picture an unit can be

seen flown from two fixing points. A chain has
been attached to a rear eyebolt through a
carabiner in order to tilt the box downwards.

ANL-2

Each carabiner has a working load of
330 kg (726 lbs.). If using other hardware, make
sure it is rated to handle the required load.

When using eyebolts it is important to bear in
mind that the rated working load is only true for a
load applied in the plane of the eye, and is
significantly reduced for other angles. The drawing
illustrates the concept. The table shows the
variation of the working load as a function of the
load angle. In the case of the eyebolt, this

ANL-2

means that the 200 kg working load becomes 60

APPENDIX: 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 in side 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.
