Jumpers

The following functions are jumper

configured:

• Headphone Gain Range Adjustment

(DAC2 HGC and DAC2 D model only)

• Headphone Switch Disable (DAC2 HGC

and DAC2 D model only)

• XLR Output Pads

• Digital Pass Through Enable

XLR Output Pad Selection (P8, P9,

P10, and 11):

Four 6-pin headers (P8, P9, P10, and P11)

allow selection of the output level at the XLR

jacks.

One pair of 6-pin headers controls the output

level at each XLR jack as follows:

• 0 dB - (Attenuator disabled) – (Jumper

plug between pins 1 and 2 of each

header)

• -10 dB – *** (Jumper plug between pins

3 and 4 of each header) – Factory Default

• -20 dB – (Jumper plug between pins 5 and

6 of each header)

Figure 1 - 10 dB (Factory Default)

Headphone Switch Disable (JP1 and JP2)

(DAC2 HGC and DAC2 D model only):

The DAC2 is configured so that the 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 defeated by adding jumpers at

JP1 and JP2.

JP1 and JP2 should be configured as follows:

• Headphone Switch enabled*** (Jumpers

Removed)

• Headphone Switch disabled (Jumpers

Inserted)

Figure 2 *** - Factory Default

Figure 3 - Disable Heaphone Switch
