OPERATION
Pushing the “on-off” switch lights up both the display and the red LED at the “mute” switch. The
“mute” switch is disabled as long as the display shows “Nyquist”. During this time the tubes are hea-
ted to operating temperature.
Approximately one minute after turn-on, the display shows the following (left to right, top to bot-
tom) and Nyquist can be de-muted:
1. Actual Format (PCM, DSD or MQA.)
2. Actual sample frequency
(44/48/88/96/176/192/352/384 for MQA and PCM or 64/128/256 for DSD)
3. Input name
aes, coax, usb, tos or ethn
4. Output Gain (0…10 dB) or Headphone Volume (0…99)
5. Phase (0° or 180°)
Since there are no differences in volume between the different digital inputs, Nyquist’s gain and
phase stay the same when switching from one input to another.
Gain selection changes to headphone volume as soon as the headphone output is activated.
The rotary knob on the left side of the front panel changes gain / headphone volume and the rotary
knob on the right side of the front panel selects the input.
