Subwoofer Output
The subwoofer output of the MAX5406 combines and
filters the left and right inputs for output to a subwoofer.
Choose the capacitor values to set the bandpass filter
to frequencies between 15Hz and 100Hz.
Figure 12 shows the subwoofer output stage configura-
tion. The subwoofer output is a monophonic signal pro-
duced by adding the left and the right input signals.
The amplifier of the subwoofer output stage produces a
bandpass response. Use the following formulas to
determine the cutoff frequencies for the bandpass filter:
where R
_S
is R
LS
or R
RS
and has the nominal value of
13.8k
Ω
, R
CSUB
has the nominal value of 10.6k
Ω
, and
C
C_S
is C
CLS
or C
CRS.
The external capacitors are as
shown in Figure 12.
Applications Information
Bass Boost
Some simple products may not need a variable bass
tone control. It may be desirable for such products
to have a bass-boost pushbutton. Tie
BASSUP
and
BASSDN
together to provide a bass-boost feature.
When tied together, the bass boost is toggled between
0dB and maximum by pressing
BASSUP
or
BASSDN
.
Unequal Source Levels
Audio sources input to the MAX5406 may not have the
same full-scale voltage swings. Use a resistor in series
with the higher voltage swing input source to reduce
the gain for that input.
For example, to reduce the gain by half, add a 10k
Ω
resistor in series with L1_H and R1_H, and a 20k
Ω
in
series with L1_L and R1_L.
