Congratulations and thank you. You are now the proud owner of the Radial PhaseQ™
500, one of the most intriguing products we have ever developed. Why intriguing you ask?
Well, simply stated, messing around with phase is kind of like bending time. Mother Nature
really gets upset when we do these things! And to add even more confusion, we are not
merely messing with the phase between two microphones, the PhaseQ can actually be used
as a whacky equalizer! So hold onto your hat… this ride will be fun.
To get you there as safely as possible, we recommend that you take the time to read this
manual. This will give you some insight on how to use the PhaseQ and what is actually going
on when you move the dials. If by chance you do not fi nd all of the answers you are looking
for, please visit the FAQ page at www.radialeng.com. This is where we post the latest bits
and pieces of information. Then, if you don’t fi nd what your are looking for there send us an
email at info@radialeng.com and we will do our very best to respond to you in short order.
Fasten your seatbelts, set the time-bend constant to year 3022... and then close your eyes.
Listen. Reality just got a whole lot more exciting!

FEATURE SET
1. BLEND – Controls the mix between the
original (dry) signal and the phase altered
(wet) signal.
®
2. PHASE SHIFT – Used to set the phase
relationship between the dry and wet
signals or between two devices when
using a stereo source.
3. INVERT - 180º polarity reverse shifts
the phase shift range from 0º to 180º to
181º to 360º for control over the complete
frequency cycle.
4. ON (phase shift) – Used to bypass the
phase shift section and compare the
original sound with the phase altered
signal.
5. FILTER – Sets the high frequency cut
off range of the low-pass fi lter. This
lets you apply the phase effect to lower
frequencies.
6. SHIFT - Changes the fi lter range from the
high range (3kHz to 38kHz) to the low
range (300Hz to 3.8kHz)
7. ON (fi lter) – Used to bypass the fi lter
section and compare the processed
signal with the original.

8. OMNIPORT - Available when used with
the Radial Workhorse, the Omniport is
assigned as a direct dry signal output for
re-patching to other devices.

OVERVIEW
The PhazeQ can be considered as two different devices in one. Its primary task is to
provide added realism by allowing two sources to be brought together in such a way that
their fundamental frequencies combine in harmony. Analogue phase control should not
be measured… you must listen and decide. The other side of the PhazeQ is destructive
creativity. In other words, we invest all kinds of time and energy trying to ensure the audio
signals are perfectly phase-aligned and then… the PhazeQ lets you completely ruin this by
allowing you to introduce radical sounding EQ curves via phase cancellation. It truly is a case
of good and bad in one box.
Phase Alignment - The good!
When two microphones are placed in a room, depending on where they are positioned with
respect to the source, the sound will inevitably arrive at a different time as it travels through
the air. When the two microphone signals are mixed together they will inevitably be out of
phase. This causes an effect known as comb-fi ltering.

Phase Shift
By altering the phase (or delaying the sound) of the nearest microphone, you can shift the
fundamental frequency so that it will more gracefully combine with the sound being captured
by the second microphone.

What is surprising is that this effect is not merely intended for mics that are broadly spaced,
but the effect is just as astounding on microphones that are close together such as an XY
confi guration. The effect is even more pronounced when combining a direct signal such as
from a direct box with a room microphone. Engineers will often spend hours moving mics to
capture the perfect tone. The PhazeQ lets you quickly do it by turning a dial.
