| Ordering number :ENN6140A Bi-CMOS IC LV1150 Virtual Surround System IC Overview The LV1150 is a virtual surround system Bi-CMOS IC for video soundtracks and audio. The main feature of this IC is the ability to create an audio ambience equivalent to that of a multichannel system by adding a signal to which virtual surround processing has been applied to the left and right channel input signals. It furthermore allows modification of this effect by the use of L+R and L-R passive matrix processing and adjustment of the surround processing level with a level control.

Modes The mode can be set using DIP switches on pins 2 and 3. * Bypass/virtual: switches between bypass and virtual modes. * L+R/L-R: Switches the virtual mode effect. Since this switching is independent of the bypass function, it has no effect in bypass mode. 2. Other notes * The level of the virtual effect can be changed by the values of the external resistors connected to pins 15 and 19. (See the sample application circuit diagram.) Note that the effect is maximum when these pins are open. * There are two options that may be attached to pins 6 and 7 and pins 9 and 10. (See the sample application circuit diagram.) High boost (SAMP1) and low boost (SAMP2) effects can be acquired using external circuits on these pins.
