Page 4: Control Functions
There may be an occasion when certain frequencies must be compressed then added back to the original “dry” signal, similar to using the IPro One as one of the bands of a multi-band compressor. A blend control was added so that this could be done without having to sacrifice an external mixer channel (if one is available) to accomplish this feat. - Page 5 +48 V: Turns on the +48 V phantom power for mics that require it. Do not enable phantom power if an unbalanced low impedance mic is used, since the mic could be damaged. The LED will light if phantom power is present. POLARITY: The polarity of the mic input can be reversed in the event that the signal is out of phase with either the line or other signals.
- Page 6 0 dB average indication on the output meters with the main level control centered and the blend turned fully CW (wet). MAIN LEVEL: The master output level control of the IPro One ™ . The center position is unity gain, with as much as 10 dB gain available.

CW, line and mic gain controls are minimum, and all on/off switches are off.) RECORDING FROM A MIC (COMPLETE SETUP): One of the most common uses for the IPro One is as a pre-amp for recording, either with an analog tape machine or a digital recorder (such as a computer or digital multi-track tape machine). - Page 14 SETTING UP A DE-ESSER: The human voice has a lot of sibilance. The high frequency content of certain consonants can quickly overload a system with harshness. To help reduce this problem, the compressor can be configured as a de-esser, or a compressor that primarily responds to high frequencies.
