3.1 Bias Mode Control Pins

The amplifier bias modes can be controlled through shorting jumpers J1 and J2. By default, the jumper shorts are left unconnected, which pulls the input signals low, leaving the device in its full-bias mode. Jumper J1 controls pin BIAS-1 and jumper J2 controls pin BIAS-2. In conjunction the jumpers can be used to place the device in its three bias modes or in shutdown.
