Operating
Standby position :
To reduce power, the dac mother board will be switched “Off” in stand-by mode. Just the front panel is activated to control
the system. Power consumption will be reduced to 0.5 Watts. Any control is possible by using the front buttons or the remote control.
Source selection:
The digital inputs can be selected by pressing the source button at the front . When the Pasithea is turned on, the input
channel that has been used recently is presented again. When pressing this button repeatedly, the next input will be selected. In case of using
the remote control, source selection can be done in two directions.
Volume control:
The volume control is a so called rotary encoder so it has no end stops like a normal potentiometer. By turning the volume
knob, the output level will be changed in steps of + or - 1 dB. After reaching a level of -63 dB the Pasithea will automatically switch to mute
mode. Increasing the volume level will disable the mute setting. In case that the Pasithea is set for “fixed output level” the volume knob has no
function except the “mute function”. The volume level is visible on the front panel display by exact Decibel level and a thermometer scale. In
fixed mode the display tells you the fixed user setting like for instance -10dBF The “F” stands for fixed.
Remark: When using the Pasithea in conjunction with a power amp and without intervention of a pre amplifier the recommended gain
of the used power amp should be between 22 and 26dB! However, the Pasithea has both hardware and software settings to
attenuate the output signal by 10dB or even 20dB when both settings are combined! As a result a wide range of power amps can be
used like for instance very sensitive tube designs. The correct settings will be described later in this document.
Mute function:
By pressing the volume knob the Pasithea will switch into ‘’mute mode’’ Pressing the volume knob again brings back the actual
volume level. The mute status is visible on the front panel display.
Error indication:
When no digital data is coming in, the front panel display will show “NO DATA”
