Control elements

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.
