摘要： Under the control of a controller, a DSP supplies audio signals received from a switch circuit to a main zone DAC, subjects the audio signals received from the aforementioned switch circuit (i.e., audio signals for main zone use) to down-mixing processing so that the number of channels matches the number of output terminals assigned to each zone, and respectively supplies the audio signals subjected to down-mixing processing to the respective switch circuits of each zone. Each of the aforementioned switch circuits supplies the audio signals received from the subzone DAC to the respective volume adjustor of each zone.

摘要： An amplification system of the invention can decrease power consumption in a power amplification section if the power amplification section need not be used. The power consumption in the power amplification section can be decreased by shutting off power feed into a voltage amplification stage by a power control section, and the power feed state into a power amplification stage from a power supply section is not changed. Thus, power feed into the voltage amplification stage of the circuit wherein a large current does not flow needs only to be controlled using limiter means also used for a different application, so that the power consumption of the power amplification section can be decreased without the need for enlarging the circuit scale, with saved space, and simply.
摘要翻译：如果不需要使用功率放大部分，本发明的放大系统可以降低功率放大部分的功耗。功率放大部分的功率消耗可以通过关闭由功率控制部分进入电压放大级的馈电来降低，并且从电源部分进入功率放大级的馈电状态不改变。因此，不需要大电流的电路的电压放大级的馈电仅需要使用也用于不同应用的限幅器装置进行控制，从而可以在不需要的情况下降低功率放大部分的功耗用于扩大电路规模，节省空间，简单。

摘要： An audio-video apparatus, which is connectable to a plurality of external devices (e.g., DVD players, TV monitors, and game devices) so as to process input signals thereof and to thereby control them individually, stores a plurality of packaged information regarding setups and operations, i.e., a plurality of scene templates, which are assigned to a plurality of scene buttons in advance. When the user presses a desired scene button, the corresponding scene template is called and read out so as to automatically realize prescribed setup and operation in connection with a desired external device. The audio-video apparatus allows the user to edit and customize scene templates assigned to the scene buttons in association with messages indicating details of scene templates, which are visually displayed on the screen.
