Little Labs IBP Analog Phase Alignment Tool / DI

IBP Analog Phase Alignment Tool

line/instrument selects between the line level xlr input on the rear (unity gain) and when pushed in the instrument in on the front (hi Z 10M with gain) for using as a direct box. Earth lift lifts the ground (pin 1)of the output xlr. Phase adjust bypass does just that, bypassing all phase adjust circuitry and allows you to use the IBP without phase adjust, as an active DI or when using the line input, a transformer isolated line driver. 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. On the rear of the unit you have a re-amp instrument level out. This will, when line level is selected bring the +4dB balanced signal down to instrument level. This output is affected by the phase adjust when selected. When instrument is selected the re-amp out is an instrument level output that is affected by the phase adjust(and can be used in a stomp box type mode). The level trim for the re-amp can be reached with a standard trim tool.

• Real time all analog phase sweep between zero and one hundred and eighty degrees... and everything inbetween.
• 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.
• Internal super quality active transformer isolated line level direct box.
• Reamp capability for bringing +4dB line level signal to guitar level.
• Buffered instrument level output for driving long guitar cable.
• Allows splitting between two instrument amps with transformer isolation and phase sweep.
• Rack mountable 4 IBPs fit in a1U 19' standard rack space.
• Extremely high quality construction. Made in the U.S.A.
