- Messenger L, a 18-way digital controlled steerable array, length 237 cm.
- Messenger XL, a 24 way digital controlled steerable array, length 304 cm.
- Messenger Two-L, a 36 way digital controlled steerable array, length 454 cm.
- Messenger Two-XL, a 48 way digital controlled steerable array, length 608 cm.
5. System considerations:
Mounting height of the Messenger XL is NOT critical. The Asymmetrical unit can be
positioned between 1.85 metre and 4 metre from the floor, measuring from floor level
to the centre of the first driver, acoustical mounting point, at the bottom of the array.
The symmetrical array is located at 1.2 metre from the floor measuring from floor level
to the centre of the first driver, acoustical mounting point, at the bottom of the array.
The acoustical centre of the Messenger can be moved over the array from bottom to
the middle and from the middle to the top in 9-stepsd. Special pre-constructed lobes
are available as well as lobes with variable opening angles.
The bottom of the array is indicated by the part that carries the service hatch behind
which the input connection board is located. The mains and the 24 VDC connectors
are located in this position. The battery for emergency purposes should be located as
close as possible to the array to avoid power loses over the cable. The built-in charger
is able to maintain the battery. It is NOT meant for quick or for normal charging!
The position of the acoustical centre of the Messenger can be chosen from a library of
lobes available from our download site at:
www.ateis-international.com
The lobes can offer you system solutions in cases where there are special
requirements on mounting position or where there are height variations in the listening
plane.
When connecting the Messenger to the mains supply, be aware that the signal earth
of the Messenger is the same as the mains earth. It is recommended that the mains is
checked and connected to a proper ground. The mains should also be uninterrupted!
If this is not the case a backup power supply can be applied to maintain operation in
case of a power failures. Check the technical details in case of a battery back-up
source and its capacity.
The audio input to the Messenger should be according to one of the following
electrical standards:
Primary input:
Transformer balanced line level signal of 0 dBu ≡ 775 mV.
Level can be electronically adjusted
Maximum recommended distance: 300 metre.
Secondary input: (Used for Ambient Noise Microphone or optional inputboard SD-1)
→♪ Un-balanced line level signal of 0 dBu or 6 dBu.
Level can be electronically adjusted
Audio output :
←♪
This output follows the signal input 1
Level can be set in M-Control
