Abstract: An AV amplifier contains an input unit to input digital data and an operation unit that receives a reproduction instruction. A switching unit switches whether to output the digital data input to a server interface unit or DSP in response to the reproduction instruction. The DSP processes the digital data output to obtain and output a two-channel signal, which the server interface unit transmits by the switching unit to a server and receives an audio signal from the server. An audio reproduction unit reproduces the server interface unit received audio signal and an audio signal output by the DSP. An output unit outputs the reproduced audio signal to each speaker and a control unit controls the switching unit and the server interface unit in response to the reproduction instruction from the user. The control unit controls the switching unit, when two-channel audio reproduction is instructed from the user.

Abstract: [Problem] To achieve compatibility between push-type and screw-type terminals of mounted printed circuit substrates. [Solution] A speaker terminal attachment base (1) allows both push- and screw-type connectors (2, 3) to be attached thereto. A connector anchoring boss part (111), whereby a terminal part (121) with a through hole (1211) is anchored, is formed upon an attachment base (1), and a through hole (1112), which connects to the through hole (1211) of the terminal part (121), is formed upon the connector anchoring boss part (111). The through hole (1112) comprises a large diameter part (11121), and a small diameter part (11122). When the screw-type connector (3) is attached, a nut (5) which sends a male screw part (312) of the connector (3) in the axial direction is non-rotatably housed in the large diameter part (11121) before a terminal plate (12) is attached. When the push-type connector (2) is attached, a flat face (11123) which is formed in the inner circumference of the small diameter part (11122) makes planar contact with a flat face (2115) of the connector (2), preventing the rotation of the connector (2).

Abstract: To enable listening with a desired number of channels at a lower cost and without wasting resources. According to the present invention, a multi-channel digital audio signal is processed through the cooperation of a plurality of AV amplifier devices. One AV amplifier device 1 serves as a master, and distributes the audio channels to be processed to the other AV amplifier devices 1 including the own device 1, and determines, on the basis of the signal processing time of each AV amplifier device 1, the output delay time of each AV amplifier device 1 such that the output timings of the analog audio signals of all AV amplifier devices 1 match each other. Then, the AV amplifier device 1 decodes the input digital audio signal into an analog audio signal for an audio channel distributed to the own device 1 by the master, and delays and outputs the decoded analog audio signal by the output delay time of the own device 1 determined by the master.
