摘要： PROBLEM TO BE SOLVED: To reduce costs by reducing a coefficient size of a phase adjustment filter (FIR filter).SOLUTION: A DSP 220 is an acoustic analysis block when an acoustic device 200 is in an analysis phase, and the DSP 220 is an acoustic adjustment block when the acoustic device 200 is in a reproduction phase. The acoustic analysis block calculates acoustic adjustment parameters of each speaker which perform acoustic adjustment at the time of reproduction. The acoustic adjustment parameters comprise a phase adjustment parameter, amplitude adjustment parameter, delay parameter, and polarity inversion parameter. The acoustic analysis block calculates the polarity inversion parameter using low-pass components of a response signal from a speaker 300 which is picked up by a microphone 400. In adjustment of acoustic characteristics at the time of reproduction, polarity inversion processing of an audio signal can be performed based on the polarity inversion parameter, and low-pass phase adjustment amount can be significantly reduced in phase adjustment processing.

摘要： PROBLEM TO BE SOLVED: To prevent heat generation of a transistor device controlling a source voltage level to be supplied to an amplifier stage from rising over a rated value in a digital amplifier.
SOLUTION: Exoergic temperature in a transistor Q1 as a first gain control means is measured and when the exoergic temperature in the transistor Q1 is over a predetermined value, a control signal for maximizing the source voltage level is supplied to the transistor Q1. Since the exoergic temperature of the transistor Q1 rises by heat loss when the source voltage level is controlled so that it becomes low, it is possible to prevent a heat quantity in the transistor Q1 from rising above a rated temperature if controlled so that the source voltage level is maximized when the exoergic temperature exceeds the predetermined value.

摘要： PURPOSE:To eliminate the disadvantage in the operation suppressing the effect of a noise voltage automatically caused to signal supply source, by providing plural signal input terminals and selecting plural input signals fed respectively from the signal supply devices connecting to the input terminals. CONSTITUTION:One of signals from signal supply sources 77, 80, 83 is fed to a signal amplifier processing section 62 by selecting input terminals 52-54. When each impedance of switches 70, 66, 63 is very low with respect to a voltage VI at a connecting point P3, the impedance between a ground electrode 52E of the terminal 52 and a reference potential point in an amplifier 51 is very low by a switch 63. A ground electrode 52E of the input terminal 52 and a ground electrode 76E at an output terminal 76 of an external signal supply source 75 are connected with a cable 85. A noise voltage equivalent to a product between a noise current flowing to a ground side lead of the cable 85 and an impedance Z4 of the lead gives very less effect onto the signal to a signal electrode 52S of the terminal 52. Thus, the effect of the noise voltage caused to the signal supply source is suppressed.
