Headphone Switch Configuration:
The DAC2 is configured so that the MAIN analog outputs will mute when a headphone plug is
inserted into the left-hand jack. This is convenient when the user wishes to switch between
headphones and speakers. This feature can be changed or defeated by moving jumpers at P1 on
the back of the front panel. Either headphone switch can be enable or disabled by moving the
jumpers.
Connect the bottom two pins with a jumper to enable the mute switch for the left-hand jack -
Factory Default (see Figure 2).
Connect the top two pins with a jumper to enable the mute switch for the right-hand jack. Add a
second jumper if necessary.
 No Jumpers - Both switched disabled
 Top Jumper Only - Right-hand switch enabled
 Bottom Jumper Only - Left-hand switch enabled - Factory Default
 Top and Bottom Jumpers - Both switches enabled
 Jumper(s) rotated vertically - Storage of unused jumper(s)
Unused jumper(s) may be stored vertically on either pair of pins.
