3.3.2.3J2 — Input Mode Jumper

To force the module amplifier IC to use the HP input regardless of the module control input state, set jumper J2 to ON.

Jumper J2 connects the HP/LINE input mode control pin on the amplifier IC directly to VDD, so that when J2 is ON, the IC is held in the HP input mode

regardless of the state of the HP/LINE module control input. When J2 is OFF, a pulldown resistor on the module holds the IC input control mode input pin low, allowing the IC to use the LINE inputs as the source of an input signal.

3.3.2.4J3 — Input and Output Mode Jumper

To force the module amplifier IC to use the HP input when in SE output mode and to use the LINE input when in BTL output mode, set jumper J3 to ON.

When jumper J3 is ON, the HP/LINE input mode control pin on the amplifier IC and the SE/BTL output mode control pin on the amplifier IC are shorted together so that both the input and output multiplexors switch simultaneously. When J3 is OFF, the input and output modes may be switched independently of each other.

3.3.2.5J4 — Fade Mode Jumper

A fade mode slowly ramps up the amplifier gain when coming out of shutdown mode and conversely ramps the gain down when going into shutdown. This mode provides a smooth transition between the active and shutdown states and virtually eliminates any pops or clicks on the outputs.

Jumper J4 connects the FADE input control pin on the amplifier IC directly to GND, so that when J4 is ON, the IC is held in fade mode and the gain slowly ramps when entering/leaving the shutdown state. When J4 is OFF, a pullup resistor on the module holds the FADE input at VDD and the amplifier switches to non-fade mode.
