Headphone Gain Reduction (JP3

and JP4) (DAC2 HGC and DAC2 D

model only):

The gain range of the HPA2™ can be set

using jumpers JP3 and JP4. When jumpers

are installed at position “A” the headphone

amplifier gain is decreased by 20 dB. When

jumpers are installed at position “B” the

headphone amplifier gain is decreased by 10

dB.

The ideal gain setting permits the user to set

the front-panel Volume Control above 40%

(10 o’clock) without the headphone volume

being too loud.

JP3 and JP4 are factory installed for a

headphone attenuation of 10 dB. This setting

is best for most applications as shown in

Figure 4 - 10 dB (Factory default). Move

the jumpers according to example in Figure

5 - 0 dB for more gain or move the jumpers

according to example in Figure 6 - 20 dB for

less gain.
