LV1150M
Operating Principles
1. 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. (See the charts.)
