5. Sound quality (low frequencies)
By varying the value of input capacitor, low-frequency characteristic can be improved.
However, it is concerned the shock noise. Please confirm in each set when the capacitance value varies.
6. Pop noise
For pop noise prevention, it is recommended to use the muting function at the same time.
Please turn on the muting function simultaneously with power supply on when the amplifier is turned on. Next, turn
off the muting function after the output DC potential stabilization.
When the amplifier is turn off, turn off the power supply after turning on the muting function.
7. Oscillation stability
Pay due attention on the following points because parasitic oscillation may occur due to effects of the capacity load,
board layout, etc.
(1) Capacity load
When the capacitor is to be inserted between each output pin and GND so as to prevent electric mirror noise, select
the capacitance of maximum 1500pF. (Conditions : Our recommended board, RL = 4Ω)
(2) Board layout
Provide the VCC capacitor of 0.1μF in the position nearest to IC.
PREGND must be independently wired and connected to the GND point that is as stable as possible, such as the
minus pin of the 2200
μF VCC capacitor.
In case of occurrence of parasitic oscillation, any one of following parts may be added as a countermeasure.
Note that the optimum capacitance must be checked for each set in the mounted state.
Series connection of CR (0.1μF and 2.2Ω) between BTL outputs
Series connection of CR(0.1μF and 2.2Ω) between each output pin and GND.
