Functional Description
5.
R
S
Summing resistor that combines the right and left line level outputs into the mono input of the bridged
amplifier. The two summing resistors in parallel determine the value of the input resistance of the bridged
amplifier.
6.
R
LFE
Resistor for the bridged power amplifier in series with R
F at high frequencies. Used in conjunction with
C
LFE to increase closed-loop gain at low frequencies.
7.
R
F
Feedback resistor which sets the closed-loop gain in conjunction with the equivalent R
S for the bridged
power amplifier.
8.
R
M1
Resistor in series with Microphone supply pin and the microphone for biasing differential input
microphones.
9.
R
M2
Resistor in series with reference ground and the microphone used for biasing differential input
microphones.
