Bluetooth Antenna
(Optional)
Attaching the external Bluetooth antenna in the
function cable kit can be helpful when the KABD is
installed in situations where more range is needed, or
if the Bluetooth signal is restricted, such as in a metal
case.
10.
Line Output (2 Channels)
(Optional)
Because the ADAU1701 has 4 DAC (analog) outputs,
and only 2 of them are used for the powered outputs
via J10, the other 2 are available via J7. These can be
wired to 3.5mm jacks, RCA jacks, or even connected
directly to another amplifier, and you can even apply
full DSP algorithms to these outputs via SigmaStudio.
For example, you could wire an RCA jack to this output
and use it as a line level
DSP’d
“sub out” and connect
your project to a powered subwoofer. You could also
use the KABD-250/230 to power tweeters in a 2-way
system, and then use this output jack to connect a
more powerful external amplifier that powers the
woofers.
11.
Programmer Connection
(Optional, but highly recommended)
Connecting a compatible programmer (Dayton Audio
ICP1 or KPX) will allow you to connect the KABD’s DSP
chip to your PC, allowing you to create advanced DSP
programs. This connection is temporary, and the
programmer can be removed when finished. See the
“SigmaStudio Connection” section of
this document
for more details.
