Little Labs IBP Junior Analog Phase Alignment Tool

Features

• Real time all analog phase sweep between zero and one hundred and eighty degrees... and everything in-between.
• Allows mics to be placed where they sound best individually, compromising mic placement due to phase problems is not necessary when using the ibp.
• +4dB XLR balanced input and outputs.
• Rack mountable 4 IBPs fit in a 1U 19 standard rack space.
• Extremely high quality construction. Made in the U.S.A.

The IBP Junior is the new, economical, basic version of the Little Labs IBP Analog Phase Alignment Tool. The Little Labs family of IBPs (In-between Phase) easily eliminate the undesirable hollow sound when combining out-of-phase and partially out-of-phase audio signals. Designed as a phase problem solving device, the IBP Analog Phase Alignment Tool has quickly become popular among audio engineers as not only a fix it tool but as a controlling audio phase creative, tonal color tool. Whether combining direct and miked signals, acoustic guitar and vocal mics, drum kit tom-tom mics, or multiple split-guitar amps, audio signals phase can be quickly and easily controlled with the Little Labs IBP Junior Analog Phase Alignment Tool.

IBP functional (From left to right): Phase adjust bypass does just that, bypassing all phase adjust circuitry. Phase invert is a simple polarity reversal as you would find on a mixing console out is 0 degrees, in is 180 degrees. Phase adjust 90 degrees /180 degrees selects between two stages (button out) or one stage of phase adjust. This allows a more extreme phase adjustment with a full swing of as much as 180 degrees or a less extreme 90 degrees of phase adjustment.

Phase center lo/hi selects between a higher bandwidth phase adjust (button out) and a primarily lower frequency phase adjust (button in). This and the phase adjust button create the phase curve. It is important to note phase is frequency dependent and is different than time. For example depending on the two sources you are combining, and whether one source is direct and one is miked- between room reflections distance from the cabinet etc. determines what the curve would need to be. (e.g. you need to get the G note in phase as well the A note).

Phase adjust knob determines the degree of phase adjust. The xlr balanced input is designed for balanced line level sources, the xlr output is impedance balanced and should feed line level pin 2 hot balanced or single ended line level inputs with pin 1 earth and pin 2 hot.
