REMOTE BASS
Connection for the supplied wire remote con-
trol (5 m).
This gives you the convenience of control-
ling the bass level remotely (see Fig. 10).
If you want to use the remote control, the
device must be operated with the low-
pass filter activated (X-OVER switch set
to position LP).
INPUT
Preamp inputs for the right and left chan-
nels. Please use high-quality Blaupunkt RCA
cables for this connection.
OUTPUT
Outputs for connecting an additional ampli-
fier (formation of chains of amplifiers). Please
also use high-quality Blaupunkt RCA cables
for this connection.
LP / HP / FULL switch
Before installing, adjust the X-OVER switch
on the power amplifier to set the low pass
filter (LP), high pass filter (HP) or full-range
setting (FULL). If you select the FULL posi-
tion, the full frequency response will be used.
Using the integrated crossovers is particu-
larly useful in the case of multi-channel
sound systems with a separate subwoofer.
In order to obtain the best sound when a
subwoofer is connected, the subwoofer must
be separated as far as the frequencies it re-
ceives are concerned, i.e. it must only be
fed with low frequencies (bass).
To ensure that this is the case, select LP and
use the crossover frequency control to ad-
just the upper frequency to between 50 Hz
and 250 Hz. This ensures that every sub-
woofer is optimally separated as far as the
frequencies it receives are concerned.
TSA 280 / TSA 2120
If HP is selected, you can use the associat-
ed crossover frequency control to adjust the
lower cut-off frequency to between 50 Hz and
250 Hz.
If you want to precisely optimise the acous-
tic settings of the crossover, we recommend
you obtain advice from a Blaupunkt dealer.
It is very important that you take into ac-
count the specifications of the loud-
speakers being used whilst you are ad-
justing the crossover.
Crossover frequency control
(LP FREQ + HP FREQ)
If the crossover is activated (LP or HP) by
adjusting the position of the X-OVER switch,
you can then use the corresponding control
to adjust the crossover frequency of the re-
spective filter to anywhere between 50 Hz
and 250 Hz (i.e. continuously variable set-
ting). This control has no function in full-range
mode.
Settings for a subwoofer
In order to obtain the best sound when a
subwoofer is connected, the subwoofer must
be separated as far as the frequencies it re-
ceives are concerned, i.e. it must only be
fed with low frequencies (bass).
1. Firstly, turn down the GAIN control on the
amplifier to minimum and set the LP fre-
quency control to its centre position.
2. Now play some music on your car sound
system that you are very familiar with and
that contains some low bass (e.g. pop
music). Now slowly increase the volume
of the subwoofer by turning the GAIN
control on the amplifier in a clockwise
direction until you feel that the sound of
the music is well balanced, i.e. the bass
is neither too weak nor overpowering.
