An apparatus is provided for remotely monitoring a plurality of amplifiers on a display device. The amplifiers are provided to process audio signals and directly or indirectly connected to a network. In the apparatus, a collecting section collects a group code from each of the amplifiers through the network. The group code is allocated to each amplifier according to a grouping system for grouping the plurality of the amplifiers. A display control section displays a tree diagram of the amplifiers according to the collected group codes on the display device as a graphical representation of the grouping system.

Remote audio amplifier monitoring system

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.

Amplifier system

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.

Amplifier controller

Interlocking flag, indicating whether or not an interlocked display should be made, can be set in association with predetermined editing operators. When any of the operators is operated, a displayed screen on a display is switched over to a screen related to the operated operator, if the interlocking flag associated with the operated operator indicates flag-ON; if not, the display device may be used to perform another function. A plurality n of channels may be divided into a plurality of layers each consisting of predetermined number m channels. It is only necessary that a limited number of operators, e.g. faders, be provided to correspond to a single layer, i.e. m channels. Any of the layers is selected, and any of the operators is used for the selected layer. A set of stereo channels can be set across different layers so as to interlock with each other in response to editing operation of the operator.

Audio signal editing apparatus and control method therefor

A plurality of displayable screens are classified into a plurality of screen groups in such a manner that two or more of the screens belong to each individual screen group. Once a desired one of the screen groups is designated by activation of a shift switch, respective tabs of the two or more screens belonging to the designated screen group are visually displayed on a display device. Then, once a desired one of the thus-displayed tabs is designated by activation of a tab switch, the screen corresponding to the thus-designated tab is displayed on the display device. Even when the tab display has been switched by designating another screen group, the screen corresponding to the last designated tab (i.e., main screen), is prevented from being changed unless another tab is designated.

Screen change control apparatus and method using tabs

A mixing console has, for example, eight signal processing channels each for processing audio signals, and indicator units respectively for the signal processing channels. Each indicator unit is to display the channel number or the note name or another short message about the channel. Each channel is provided with a control element for commanding a control such as setting equalizer parameters. When a control element is actuated and held for more than one second, for example, such an actuation causes the designation of a channel about which a long message is displayed by using the indicator units for the eight channels in series.

Device, method and computer program for displaying signal information

There is provided an electronic apparatus that is free of the problems with the prior art and is capable of achieving higher efficiency of cooling the interior of the casing without sacrificing cost reduction and designing compact in size. A casing houses a plurality of circuit boards having electronic parts mounted thereon and at least one high load part that generates heat. The casing has exhaust ports formed therein for heat radiation and exhaust ports for heat radiation. The plurality of circuit boards are comprised of a first circuit board and a second circuit board. The first circuit board is disposed to extend substantially horizontally, and the second circuit board is disposed to extend substantially vertically with a horizontal gap provided between the first circuit board and the second circuit board. The at least one high load part is arranged below the horizontal gap, and the exhaust ports are arranged above the horizontal gap.
