摘要： The channels of a plurality of two-channel amplifiers are grouped into channel groups in response to a grouping operation. When one of the amplifiers is selected, an amplifier detail screen having two elements corresponding to the two channels is displayed. Acquired operation data or level data are displayed via the two elements. In response to a channel selecting operation one channel of an amplifier among a plurality of channels of the amplifiers is selected and a channel detail screen displayed, on which only one of two elements is placed while the other element is vanished or invalidated. In response to a group selecting operation a first group detail screen is displayed, on which two elements are placed. Data is acquired independently for each of the two channels to obtain two visual data for the two channels. If a selected group contains only one of the two channels, a second group detail screen is displayed, on which one element corresponding to the one channel is placed.

摘要： [Object] An audio signal from an audio signal source 2 is amplified in an amplifier 4, and the amplified audio signal is supplied through a loudspeaker line 6 to a plurality of loudspeakers 8 connected in parallel with each other. A test signal from a DSP 10 containing one or both of a frequency near the lowest frequency of the human audio frequency band and a frequency near the highest frequency, is combined with the audio signal in a combiner 13 and supplied to the loudspeaker line 6. Output signals of a current detecting circuit 14 and a voltage detecting circuit 16 disposed in the output of the amplifier 4 are supplied to a DSP 10 to analyze frequency components of the test signal, and a composite impedance of the loudspeakers 8 and the loudspeaker line 6 is computed based on the frequency component analysis. The DSP 10 compares the composite impedance with a threshold value to detect line breakage or decrease in impedance of the loudspeaker line.

摘要： The resonance frequency of a magnified-sound space is determined based on a basic amplitude/frequency characteristic obtained by sound magnifying, from a speaker (13) located in the magnified-sound space (40), a predetermined measurement signal and then receiving the sound by use of a microphone (14) located in the magnified-sound space (40); also based on a first amplitude/frequency characteristic obtained by sound magnifying, from the speaker (13), the measurement signal and a first delayed signal, which is obtained by delaying an output signal from the microphone (14) by a first delay time of zero or more, and then receiving the sound by use of the microphone (14); further based on a second amplitude/frequency characteristic obtained by sound magnifying, from the speaker (13), the measurement signal and a second delayed signal, which is obtained by delaying an output signal from the microphone (14) by a second delay time of zero or more, and then receiving the sound by use of the microphone (14). The second delay time is different in value from the first delay time.

摘要： A howling margin measuring device 20 comprises processing means 28 composed of gain controlling means 21 and a compressor 22 which are connected in series and controlling means 23. The gain controlling means 21 outputs an input sound signal after giving a gain thereto. If the level of a sound signal input to the compressor 22 is equal to or higher than a threshold level, the compressor 22 outputs the sound signal after compressing it with a specified ratio. The controlling means 23 is capable of controlling the gain of the gain controlling means 21 and reading the compression level of the compressor 22. The controlling means 23 reads the compression level of the compressor 22 while gradually increasing the gain of the gain controlling means 21, determines whether or not howling has been generated based on whether the read compression level has a value equal to or higher than a specified value, and calculates a howling margin based on the gain of the gain controlling means 21 when it is determined that howling has been generated.
摘要翻译：啸叫余量测量装置20包括由串联连接的增益控制装置21和压缩器22组成的处理装置28和控制装置23.增益控制装置21在给予增益之后输出输入声音信号。如果输入到压缩机22的声音信号的电平等于或高于阈值电平，则压缩机22以规定的比例对其进行压缩后输出声音信号。控制装置23能够控制增益控制装置21的增益并读取压缩机22的压缩电平。控制装置23在逐渐增加增益控制装置21的增益的同时读取压缩机22的压缩电平，基于读取压缩级别是否具有等于或高于指定值的值来确定是否已经产生啸叫，并且当确定已经发出啸声时，基于增益控制装置21的增益来计算啸叫余量产生。
