2. Tone Control
a) Bass: Setting the Cut-off frequency
Bass Filter
M changes by gain setting of Tone.
M
≈
2.65 (±15dB)
M
≈
3.45 (±10dB)
M
≈
8.10 (±5dB)
b) Treble: Setting the Cut-off frequency
N changes by gain setting of Tone.
N
≈
0.76 (±15dB)
N
≈
0.58 (±10dB)
N
≈
0.25 (±5dB)
3. BBE, Surround mode and "OUT" switch settings
The click noise may be generated by changing the BBE, Surround mode setting and “OUT” switch.
Provide the external circuit for avoiding the click noise on above condition.
4. External parts for BBE circuits
The constant of capacitors connected to the terminals No.2, 3, 28 and 29 are designated by BBE Sound Inc.
Do not change the constant of these capacitors without the approval of BBE Sound Inc.
5. AUX1, AUX0 Terminal
AUX1/0 are enable to control external logic circuit is
Source current
: 1mA typ. (Ta=25
C)
Sink current
: 0.5mA typ. (Ta=25
C)
6. Capacitor for Reference Voltage (21pin)
22
μ
F should be recommended for ripple filter connected to Vref terminal (21pin).
Reducing this capacity may cause to reduce the maximum attenuation level and to increase the output
noise.
