    2 Setup 2.7 Input Sensitivity Switch A two-position Input Sensitivity switch is located on the back panel near the input connectors (Figure 2.11). Your amplifier is shipped from the factory with this switch set to the 1.4V position. At this setting, a 1.4V input signal will drive the amplifier to full power into an 8-ohm load when the level controls are turned to maximum.
