Magnat Cinema Ultra AEH 400-ATM Handbuch Seite 7

General remarKS COnCerninG SetUP
The loudspeakers offer several options for wall mounting. Wall-mounting brackets are fitted on the rear.
Alternatively, the speakers can be mounted using a VESA standard wall bracket. Distance between the hole
100x100mm M4.
Four self-adhesive rubber feet are included for the front speaker for setting up on an existing loudspeaker or
shelf. When placing the unit on top of another loudspeaker, please check first whether the top of your exist-
ing front speaker is big enough to accommodate the Magnat AEH 400-ATM. An area of around 280x188mm
is needed. For secure positioning, all four feet of the add-on speaker must be in contact with the top of the
front loudspeaker. Please always make sure that the main axis of the integrated coaxial loudspeaker has a
clear line of sight to the ceiling without any sound-absorbing or reflecting obstacles. Only in this way can the
desired sound reflection via the ceiling function as wished.
POSitiOninG tHe SPeaKerS
the optimum positioning of the speakers depends on their use:
- on-top speakers for Dolby atmos:
One AEH 400-ATM is placed on top of each of the existing front speakers (Fig. 2). If this positioning is not
desirable or the area available is not sufficient, the Atmos speakers are placed in the immediate vicinity of
these locations.
When using four AEH 400-ATM's and direct emission speakers in the surround sound area (no dipoles), the
rear Atmos speakers are placed on top of the surround sound speakers or as close as possible to them (Fig. 2).
If this is not possible, the rear Atmos speakers are placed near the rear wall at the same height and the same
distance from each other as the front pair. The baffles must always be set at an angle to point into the room.
Please ensure for this operating mode that the switch on the connector terminal is in the "Atmos" position
shown on the type plate.
The Magnat AEH 400-ATM has a matching size and look to fit perfectly on top of the Cinema Ultra front
loudspeaker LCR 100-THX.
- Ceiling speakers for Dolby atmos:
Two AEH 400-ATM's are secured to the ceiling of the room using VESA brackets (100x100mm, M4). The
optimum position is slightly in front of the listening position (approx. 80° in relation to the listener) and the
distance between the two ceiling speakers should correspond to the distance between the left and right front
speakers (Fig. 3a/b).
When using four AEH 400-ATM's as ceiling speakers, these are also placed at the same distance from each
other as the front speakers, but further to the front and rear. The optimum location in relation to the listening
position is at an angle of 45° and 135° in relation to the listener (Fig. 4a/b). The baffles must always be set at
an angle towards the listener. Please ensure for this operating mode that the switch on the connector terminal
is in the "Direct" position shown on the type plate.
For acoustic reasons, we would advise against mixed operation of indirect emission (ceiling reflection) and
direct emission.
- Wall or ceiling speakers for other uses:
The AEH 400-ATM is also suitable as an add-on speaker for other audio formats and as a presence or wide
speaker for modern AV amplifiers and receivers. With regard to the optimum positioning for these operating
modes, please see the user guides and manufacturer recommendations for the respective devices.
For the AEH 400-ATM, we generally recommend using the VESA bracket for wall or ceiling mounting in these
operating modes. Please make sure that the baffles of the add-on speakers are always pointing into the room
towards the listener and that the switch on the connector terminal is in the "Direct" position shown on the
type plate.
