6. PLACEMENT AND MOUNTING
Place the speakers ahead of the microphones. Feedback
(howling) occurs when the microphones pick up the sound
that comes out of the speakers and feeds it back to the
system. Feedback can cause damage to your unit. If space is
limited, direct the speakers towards areas where there are no
microphones to minimise feedback.
When using a turntable, place the speakers far from the
turntables. If the speaker signal is picked up by the stylus and
re-amplified, low frequency howling will occur. The use of a
very heavy base for the turntable is recommended.
Tripod use
The unit is equipped with a built-in tripod socket for use with
standard 35-mm tripods such as the D.A.S. TRD-2. The socket
has a locking screw to fix the orientation of the box; make
sure it is unscrewed enough before mounting the box onto the
tripod, so that the screw is not in the way of the tripod and
does not protrude from the tripod socket. Be careful not to
raise the box too high on the tripod, as it may become
unstable.
Place the speakers as high as possible. For best results, try to
place the high frequency unit above the audience’s heads. If
the loudspeakers are located too low, the listeners at the end
of the room will not hear quality sound.
Stage monitor use
The angle on the back of the speaker allows for floor monitor
use without extra accessories. If several DS-112A/115A are
used on the same stage, the volume control allow for each
box to have its own volume even when using a single monitor
mix.
Flying
Only experienced installers should fly speaker boxes. When
flying enclosures from ceiling support structures, extreme care
should be taken to assure the load bearing capabilities of the
structures, so that the installation is absolutely safe.
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 on this respect. Up to
three DS-112A/115As can be flown vertically from one
another.
The DS-112A/115A provides three M8 threaded flying points
on the top of the box , two on the bottom and four on the
back. The ANL-1 set is a set of four eyebolts and four
carabiners for flying that is available separately. The following
illustration shows the detail of the ANL-1’s components.
The following illustration shows flying of a DS-112A/115A
enclosure. It can be seen that the two front upper points are
used for hanging, using the back upper point for vertical
aiming.
