摘要： In an audio network system constructed from a main node and a plurality of satellite nodes each having a plurality of ports, the main node generates and transmits a main packet including audio signals of a plurality of channels. Each satellite node selects one of the plurality of ports in turn, and confirms whether the main packet arrives at the selected port every predetermined period or not. When the main packet arrives at the selected port every predetermined period, the main packet is received via the port by continuing selection of the port. In the case where reception of the main packet is lost, one is selected from the plurality of ports in turn, the operation to confirm arrival of the main packet is restarted, and another port at which the main packet arrives at the present stage is automatically found.

摘要： An amplifier controller for controlling a plurality of amplifiers connected therewith is provided. Each of said amplifiers is provided with one or more audio output channels. The amplifier controller operates in two modes of solo mode and normal mode. When the solo mode is initiated, the amplifier controller instructs all of the amplifiers to turn off output of all audio output channels provided in the amplifiers, and only in the solo mode, according to selection of an output channel for which solo output is to be performed, the amplifier controller instructs the amplifier provided with the selected channel to turn on output of the channel, and instructs each of the amplifiers provided with an audio output channel other than the selected channel to turn off output of the audio output channel.

摘要： Disclosed herein is a speaker system unit with a cone type vibration plate, a horn and a diffuser. The horn is disposed such that a small-diameter opening thereof is positioned inward from a front opening of the vibration plate, and an outer surface of the horn is arranged along an inner surface of the vibration plate to form a first acoustic path. The diffuser has a base portion, a front end portion and an outer peripheral surface extending therebetween, and is disposed such that the base portion is positioned inward from a front opening of the horn, opposite the small-diameter opening of the horn. The diffuser has a specific shape such that the outer peripheral surface expands along an inner surface of the horn to form a second acoustic path and then narrows toward the front end portion of the diffuser.

摘要： In some cases, constant directivity of a speaker system is desirably obtained in a wider frequency range. However, a speaker system using a constant directivity horn is frequently used in combination with a box speaker containing a woofer unit. Such a system becomes large in size. Furthermore, constant directivity is desirably obtained in a lower frequency. A speaker system 10 includes an enclosure 20, a first speaker unit 30 for low frequency and a plurality of second speaker units 31, 32, and 33 for high frequency. The enclosure 20 includes a front plate portion 21 which is a baffle plate and a rear plate portion 23. A length of the rear plate portion 22 in a first direction perpendicular to a forward and backward direction is shorter than a length of the front plate portion 21 in the first direction. The first speaker unit 30 and the second speaker units 31, 32, and 33 are mounted to the front plate portion 21. The plurality of second speaker units 31, 32, and 33 are arranged in the first direction. Vibration plates of the plurality of second speaker units 31, 32, and 33 are located in the vicinity of the front plate portions 21 in the forward and backward direction.

摘要： When any one of a plurality of amplifiers has been selected in response to amplifier selecting operation, an amplifier Detail View of the selected amplifier is displayed, where corresponding parameters are displayed via elements of the amplifier Detail View. When any one of a plurality of groups has been selected in response to group selecting operation, a group Detail View of the selected group is displayed, where maximum and minimum values detected from among values of a parameter of individual amplifiers of the selected group are displayed via a band-shaped element of a corresponding fader element. In another example, where a hierarchical group is selected in a tree display section on a control screen, respective state information, including parameter values or states of parameters, of a plurality of amplifiers belonging to the selected hierarchical group is displayed in a state information section.
