User manual SONY TA-VA8ES

[. . . ] To prevent fire or shock hazard, do not expose the unit to rain or moisture. Do not install the appliance in a confined space, such as a bookcase or build-in cabinet. Should any solid object or liquid fall into the cabinet, unplug the amplifier and have it checked by qualified personnel before operating it any further. If you have any question or problem concerning your amplifier, please consult your nearest Sony dealer. [. . . ] This amplifer uses digital signal processing to reproduce the sound effects of various listening environments, such as a movie theatres and concert halls (etc. By adjusting the surround parameters you can control these sound elements to create a custom listening environment. Before sound reaches our ears, it is reflected many times between the left and right walls, ceiling, and floor. In a large room, sound takes more time to bounce from one surface to another than in a smaller room. The ROOM SIZE parameter lets you control the spacing of the early reflections to simulate a sonically larger (L), or smaller (S) room. You can make the surround sound more effective by delaying the output from the rear speakers (delay time). For example, if you've placed the rear speakers in a large room or apart from your listening position, set the delay time shorter. When sound is reflected off soft material, such as curtain, the high frequency elements are reduced. A hard wall is highly reflective and does not significantly affect the frequency response of the reflected sound. The WALL TYPE parameter lets you control the level of the high frequencies to alter the sonic character of your listening environment by simulating a softer (S), or harder (H) wall. Start playing a programme source encoded with Dolby surround sound. Press DPC MODE until the SURROUND indicator lights up. If you sit in the front of a room, you hear more direct sound from the front speakers. As you move to the rear, the reflected sound increases. Similarly, the reflected sound changes when you move from left to right, and vice versa. The FRONT/REAR and LEFT/RIGHT parameters let you control the balance of direct and reflected sound to simulate your listening position. In the FRONT/REAR parameter, "F" signifies the front of the room and "R" signifies the rear. In the LEFT/RIGHT parameter, "L" signifies the left side of the room and "R" signifies the right side. This parameter adjusts the length of time required for the reverberation (echoes) generated from a given sound to attenuate ­60 dB. You can choose shorter (S) or longer (L) reverberation times. note The EFFECT parameter allows you to adjust the overall presence of the sound field. You can adjust the tone of all sound fields, including Dolby Surround. [. . . ] The acoustics where you hear the sound affect the way these three sound elements are heard. These sound elements are combined in such a way that you can actually feel the size and the type of a concert hall. Select WIDE mode if you have front and rear speakers and a large centre speaker. With the WIDE mode, you can take full advantage of Dolby Surround sound. [. . . ]
