48 V Phantom Power Supply

The Preference Mic Pre provides 48 volt phantom power for micro- phones requiring external current (generally condenser microphones). Such microphones are dependent upon a clean, consistent and noise-free power supply for optimal operation and audio quality. The Preference Mic Pre continuously delivers precisely 48 V and a maxi- mum current of 14 mA, which will power all microphones.

IMPORTANT: All microphones with balanced, ground-free outputs can be used with the phantom power activated. Unbalanced microphones may only be used with phantom power deactivated.

Phantom power should only be activated when using microphones that require it. Please be sure to deactivate phantom power with all other microphones (including tube microphones which are supplied from their own power supply, thus need no extra phantom power supply).

ALWAYS FOLLOW THESE RULES WHEN WORKING WITH PHANTOM POWER – THE INPUT STAGES OF THE PREMIUM MIC PRE CAN BE DAMAGED IF YOU DO NOT ACT ACCORDINGLY:

1)First connect the microphone to the Preference Mic Pre.

2)Then activate phantom power – you can start working now.

3)When you have finished recording, turn the phantom power off first.

4)DO NOT disconnect the microphone from the Preference Mic Pre UNTIL phantom power has been switched off for a minute and all residual current is discharged.

Pad

The Pad function allows you to attenuate the input signal by 20 dB so that you can process even very high levels, i.e. from drums or brass instruments.

If the VU meter shows levels above +3 dB even while Mic Gain is set very low (and the -10 dB button deactivated), the time has come to press the Pad button. It illuminates when it is activated.
