摘要： A channel divider that can suitably set a crossover frequency when a biwiring-connectable multiway speaker system including network circuits are used is provided. The channel divider includes a low-pass filter LPF and a high-pass filter HPF for dividing a band of a sound signal into a first output signal and a second output signal so as to output the signals, and a control circuit for controlling the filters. The channel divider has a sound output mode in which the control circuit sets a cutoff frequency fcL of LPF to a value higher than fc0 by about ⅙ to 1 Oct., sets a cutoff frequency fcH of HPF to a value lower than fc0 by about ⅙ to 1 Oct., and outputs the first output signal and the second output signal including frequency bands fcL to fcH when any crossover frequency fc0 for defining the band division is specified.

摘要： When a switching amplifier transitions into a power-off state, a switch is turned off and a power supply controller forcibly discharges a capacitor and forcibly reduces a reference potential with respect to a second power supply voltage. Since a logic power supply voltage reduces by the same amount as the reference potential, the logic power supply voltage from a viewpoint of the reference potential is fixed. A constant current circuit reduces a constant current according to the reduction in the reference potential with respect to the second power supply voltage, and reduces a first electric current and a second electric current. Before the logic power supply voltage from the viewpoint of the reference potential reduces, the first electric current and the second electric current are reduced, and an operation of a pulse generating unit can be ended in a normal state.
摘要翻译：当开关放大器转换到断电状态时，开关断开，电源控制器强制地放电电容器并强制地相对于第二电源电压降低参考电位。由于逻辑电源电压与参考电位相同的量减少，所以从参考电位的角度来看，逻辑电源电压是固定的。根据相对于第二电源电压的参考电位的减小，恒流电路减小恒定电流，并且减小第一电流和第二电流。在从参考电位的角度看，逻辑电源电压降低之前，第一电流和第二电流减小，并且可以在正常状态下结束脉冲发生单元的操作。

摘要： A current mirror circuit converts a positive-side supply voltage of a second power supply with respect to a reference potential into an electric current so as to supply the electric current to a current/voltage converting section. The current/voltage converting section converts the electric current from the current mirror circuit into a voltage with respect to the reference potential of a first power supply so as to supply the voltage to a feedback input terminal of a switching controller. Therefore, although the reference potential of the first power supply supplied to the switching controller is different from the reference potential of the second power supply, the electric current from the current mirror circuit is not influenced by the reference potential.

摘要： There is provided a multichannel audio amplification apparatus including a speaker detection circuit for detecting whether or not a speaker is connected to an arbitrary speaker terminal of speaker terminal groups TA and TB, and an operating circuit and a display circuit connected to a control circuit. Even in a case where one of two speaker groups of A and B types connected to the multichannel audio amplification apparatus cannot be connected with a surround speaker for reproducing only a surround sound, a listener is prevented, by indication, from carrying out on the operating circuit an erroneous operation or setting which otherwise might be liable to occur both in a case where the B-type speaker group including no surround speaker is connected to the multichannel audio amplification apparatus and in a case where the B-type speaker group is not connected thereto.

摘要： When an output voltage from the amplifying circuit includes a positive DC voltage, an electric current continuously flows in a power source voltage, a load, and a reference voltage in this order. As a result, the reference voltage increases so as to be a first threshold voltage or more . The detecting section detects that the reference voltage is the first threshold voltage or more. When the output voltage from the amplifying circuit includes a negative DC voltage, an electric current continuously flows in the reference voltage, the load, a grounding potential in this order. As a result, the reference voltage reduces so as to be a second threshold voltage or less. The detecting section detects that the reference voltage is the second threshold voltage or less.

摘要： When a signal representing a first set value or more is received from a detecting section, a determination is made whether a boost value is a predetermined value or more. When the boost value is the predetermined value or more, a currently set boost value is reduced by a predetermined step, so that a new boost value is set. Further, when the boost value is less than the predetermined value, a currently set volume level is reduced by a predetermined step, and a new volume level is set. Therefore, in a case when the set boost value is gradually reduced and the boost value is finally less than the predetermined value, the audio signal is still the first set value or more, the volume level is further reduced by each predetermined step. Therefore, an audio signal can be securely prevented from being clipped.
摘要翻译：当从检测部接收到表示第一设定值以上的信号时，判定升压值是否为规定值以上。当升压值为预定值或更大时，将当前设定的升压值减小预定的步长，从而设定新的升压值。此外，当升压值小于预定值时，将当前设定的音量降低预定步骤，并设定新音量。因此，在设定升压值逐渐降低且升压值最终小于预定值的情况下，音频信号仍然是第一设定值以上，通过每个预定步骤进一步减小音量。因此，可以可靠地防止音频信号被剪切。
