FD 18 LF
FD 18 L
Protection cover made of steel sheet for DL 18/1 and DL 18/2 with two push-out holes for cables. Four mounted screws to attach terminals and cable clamps. The enlarged volume betters the sound of the inserted speaker.Unsuitable for fire protection ceilings (F30). Fire protection housing systems (FlamoX) are available from KAISER, 58579 Schalksmühle, Germany.
BS 130 - 4 Ohm
Structure-borne sound converter for bass frequencies. The units are attached to a surface which is able to resonate, which causes it to oscillate (e.g. a panel of a car body, the base construction of a settee etc.). No enclosed cabinet is required. Using the BS 130 - 4 Ohm, this enables the lowest bass frequencies, such as those used for effects in films, to be reproduced in such a way that they are felt through the body rather than heard.

AMP 2.2
Stereo amplifier with level controls, e.g. for multimedia applications. Suitable for use with small loudspeakers with impedances of 4 to 8 ohms. Robust metal housing with two fixing lugs. Can be connected directly to the line out or headphones socket of a PC audio card, while the input sensitivity is regulated via the level control. Power supply (12 V) is via a mains adapter (not supplied) or the computer's on-board power supply. Short-circuit proof.
Differences between AMP 2.2 and AMP 2.2 LN:
- Different signal-to-noise ratio
- Different input sensitivity for full conduction
For mobile audio application (mobile phone, MP3 player etc.) we recommend the AMP 2.2, for non-portable products (CD player, computer) we recommend the AMP 2.2 LN.
