GainStation 8
15
POWER
Switches the unit on or off. The switch illuminates with delay,
because it is fed by the 250 V anode power – don’t panic.
If the tube stage is active when the unit is switched on, it can
take several seconds before a signal can be heard—this time is
necessary for the tube to reach operating temperature.
IMPORTANT NOTE: Never disconnect the GainStation 8 from its
external power supply while the unit is switched on. Always turn
it off first and wait at least one minute, so that all current can
dissipate, before disconnecting the multipin connector. Failure
to do so can cause severe damage to components.
LED LEVEL DISPLAY
The level display shows the peak level before output level
control. A special circuit allows the LED‘s to vary in brightness
to display in-between values. The -30 LED illuminates weakly at
-30 dB and reaches full brightness at 0 dB. The 0 dB LED illumi-
nates weakly at 0 dB and reaches full brightness at +9 dB and so
on.
The CLIP LED operates post-CLEAN GAIN stage and displays
clipping at this point in the signal path. It will not react to tube
saturation in the tube stage, since this can be a desired effect.
