Input / Link 1 - 2
. Audio signal inputs and links through speakON® NL4 connectors.
They are connected in parallel between them and with the two front connectors.
With the NL4 topology of these two
Input / Link
connections, it is possible to handle two
signals over the 1+/1- and 2+/2- poles. Depending on the application, it can be the same signal
traveling over both.

Output Ch. 2
. Audio signal output through speakON
®
NL4 connector to pass the signal present in
the 2+/2- poles of the
Input / Link
1 and 2, and the front connectors. This signal outputs through
the 1+/1- poles.
In example, this output can be used to deliver full-range signal to the top units in the system,
simplifying the wiring between the amplifier and the speakers. Find more about this in the
Applications
section.
B 15A SELF-POWERED SUBWOOFER
The
B 15A
is the self-powered version of the
B 15
subwoofer. It consists in a single 15" driver in a vented
box, powered by an updated 800 W Class-D amplifier. Same as B-Line passive models, its improved port
design smooths the airflow and maximises system capability.
Integrated DSP-presets allow to load different system setups to be used with different SE AUDIOTECHNIK
®
products. In addition, the Directivity function enables end-fire or cardioid setups and thus, control the
sound radiation in the low frequencies.
Finally, its efficient design and compact size guarantees safe and versatile placement even in outdoor
environments, where an additional rain-protection cover can be used to protect the amplifier panel
from light rainfall.

High SPL with deep bass and reduced enclosure size
-
DSP-Presets for easy subwoofer arrays setup
-
Built-in DSP and 800 W of class-D amplification

®
connectors
on the back, these passive models include two additional located on the front. This guarantees wiring
flexibility and ease of use, reducing setup time even in large configurations.
