Operating your Zdac

Front Panel Operation

Power Button
Pushing the Power button turns on the Zdac.
The most recently selected digital input will illuminate green to indicate that the Zdac is on.
There is no separate power on indicator.
Pushing the Power button again turns off the Zdac. The Zdac does not have a standby indicator.
Input Selector Knob
This selects the digital input you wish to hear. The mute circuit employs precision relays so you won't
hear any transient popping or thumping noises when you select the inputs.
Note: Avoid changing Zdac inputs while your system is playing at very high volume.
Input Indicators
The selected input will illuminate green. Available inputs are Opt, Coax and USB.
Headphone Jack
The Zdac headphone jack accepts a standard 1/8" (3.5 mm) stereo mini plug. It is driven by a high
current, low noise operational amplifier running in pure class A. It can drive headphones from 32 ohms
to 600 ohms at substantial undistorted listening levels. If your headphones use a ¼" (6.3mm) plug you
can use a 6.3 mm-to-3.5 mm stereo adaptor for the Zdac headphone jack. Some headphones include
this adapter.
Note: The Zdac's Analog XLR and RCA output jacks will be automatically muted whenever you
insert a headphone plug into the Zdac headphone jack.
Headphone Volume Knob
The headphone volume knob controls a high quality analog potentiometer. It adjusts only the output
level of the headphone jack and it has no effect on the Analog XLR or RCA jack output level.
Note: Headphones can create dangerously high sound pressures levels without audible distortion
you would hear from loudspeakers at comparable volume levels. Please do not listen at high
volumes for an extended time. When you listen with headphones you won't have the benefit of
family (or neighbors) telling you to "turn it down!"
