A multichannel compensating audio system includes first and second compensation channels to psychoacoustically minimize deviations in a target response, to psychoacoustically move the physical position of a speaker and / or to psychoacoustically provide a substantially equal magnitude of sound from a plurality of speakers in a plurality of different listening positions. The first compensation channel may include a series connected delay circuit, a level adjuster circuit and a frequency equalizer circuit that generates a first compensated audio signal from a first audio signal. The second compensation channel may include a series connected delay circuit, a level adjuster circuit and a frequency equalizer circuit that generates a second compensated audio signal from a second audio signal. A first summing circuit is configured to receive at least the first audio signal and the second compensated audio signal and generate a first output signal for provision to a first speaker. A second summing circuit is configured to receive the second audio signal and the first compensated audio signal and generate a second output signal for provision to a second speaker. The first and second output signals may be output by the first and second speakers into a listening space and are acoustically perceived by a listener.

An ink-jet recording apparatus has ink jetting nozzles through each of which a photocurable ink is jetted for recording an image onto a recording material by an ink jetting method. The apparatus includes a color ink recording head for jetting color ink, a clear ink recording head for jetting clear ink; and an ink amount determining section for determining an amount of the clear ink to be jetted from the clear ink recording head, by causing at least one of the color ink recording head and the clear ink recording head to record a predetermined test pattern on the recording material, and on the basis of a glossiness of the recorded test pattern. A glossiness measuring device measures the glossiness, and the ink amount determining device determines the amount of the clear ink based on the measured glossiness.

A keyboard device for an electronic keyboard instrument, including several keys arranged side by side in a left-right direction, a hammer support disposed rearward of the keys, a plurality of hammers pivotally supported by the hammer support to be pivotally moved in accordance with key depression, and a key switch having a plurality of switch bodies provided in association with the respective hammers and a switch board mounted to the hammer support. The hammer support has a hammer supporting part for supporting the hammers and a switch mounting part to which the key switch is mounted, and is formed by an injection molded article of a predetermined kind of synthetic resin.
