IMPED. Ω
This 3-way switch allows you to select between three input impedances for the Mic Input. In general, higher impedances increase levels and emphasize high frequencies, while mids and bass frequenices are dampened. Conversely, a lower impedance causes lower levels and emphasizes bass and mid frequencies.
The Imped. Ω-Wert does not have to be equivalent to the output impedance of the microphone. We recommend the highest impedance setting as starting position (10.000 Ohm). Now it must be evaluated acoustically, if lower settings are delivering better results.
PHANTOM
The GainStation 8 provides 48 Volt phantom power for micro- phones requiring external current (generally condenser micro- phones). Such microphones are dependent upon a clean, consis- tent and noise-free power supply for optimal operation and audio quality. The GainStation 8 continuously delivers precisely 48 V and a maximum of 14 mA, which will power all micro- phones.
IMPORTANT NOTE: All microphones with balanced, ground-free outputs, including tube microphones, can be used with the phantom power activated. First connect the microphone to the GainStation 8, then activate the phantom power. When finished, first deactivate the phantom power and wait at least 30 seconds before disconnecting the microphone to allow residual current to discharge.
Phantom power should only be activated when using micro- phones that require it. Please be sure to deactivate phantom power with all other microphones. Unbalanced microphones may only be used with phantom power deactivated.
The 48V LED illuminates to indicate activated phantom power. When deactivating phantom power, it can take several seconds for the LED to go out, since the 48 V current dissipates rather slowly. When changing microphones, you should wait until the LED is completely dark before re-patching.
