PHAZER™-PHASEADJUSTMENTTOOL
INTRODUCTION
The Radial Phazer is a phase adjustment tool designed to allow the user
to quickly time-align two sources to create fat rich tones or open the audio
landscape to all kinds of new and exciting sounds. Line level connections
are generally done via the insert point of the console or by taking a direct
feed from a line level device such as a mic preamplifier. Power comes
from the 15VDC supply that is provided.
ThePhazerfeaturestwobasiccontrolsections:avariablephaseshiftthat
spans from 0º ~180º and a low-pass (high-cut) filter. Both control sections
feature an on-off switch that lets you monitor the effect when introduced
into the signal path. Usually, one would start by adjusting phase of the
nearestsource(ieclosemicversusroom mic) by turning the knob untilthe
two sources ‘sound’ right. *Note that a polarity reverse switch is used to
togglethephasefromthe0º ~180º to 181º ~360ºrange.This is performed
at the XLR output.
As microphones and/or direct boxes can often be phase reversed, you
should try depressing the polarity reverse (360º) switch to see what range
sounds best. Keep in mind that it is impossible for all frequencies to line
up or be in phase as each frequency has a different wavelength and
the physical distance and/or propagation time will vary. Ultimately, when
using the Phazer you must use your ears to find what sounds best to you.
Because most of the energy is in the low frequency spectrum, you will find
that most of the audible effect will occur in the first half of the control range
between8o’clockand11o’clock.This is normal.Asyoumovebeyondthis
point, the potentiometer will mostly affect higher frequencies.
Once you have found the ‘sweet spot’ try engaging the low-pass filter to
hearitseffect. Thisfilter is designed to roll offhighfrequenciesso that you
can focus the Phazer’s effect on the fundamentals or bass frequencies.
When the knob is fully clockwise, the filter is essentially out. As you rotate
counter-clockwise,thefiltercut-offpoint will begin to take effect.There are
two ranges to choose from.
Afun effect is to combine a direct feed such as coming from a guitar amp
direct box like the Radial JDX with a mic’d feed from the amplifier. By
purposely setting these out of phase you can recreate tones reminiscent
of Tom Schulz’s 1970s Boston that are absolutely stunning! The Phazer
is a fun creative tool for studio and a must have to quicken up live sound
checks. Have fun!

FEATURES AND FUNCTIONS
1. PHAZER ON: Bypasses the Phazer from the signal path to allowA/B
testing of phase effect.
2. SHIFT: Polarity reverse allows you to access the 181° to 360° phase
range and corrects inverted signals.
Out position: 0° to 180°. In position: 180° to 360°.
3. PHASEADJUST: Controlsthephaserotationovera180° range. Used
with SHIFT control to cover full 360° phase rotation.
4. FILTER ON: Bypasses the low-pass filter for quickA/B comparison of
the un-filtered signal.
5. FILTER RANGE: Selects the frequency cut-off range for the FILTER
ADJUST control and allows the phase effect to be applied only to
frequencies below the cut-off point.
In position: 300Hz to 3.8kHz. Out position: 3kHz to 38kHz.
6. FILTERADJUST: Setsthecut-offfrequencyfor the low-passfilterwithin
the range set by the RANGE switch. Frequencies above the cut-off
are rolled-off.
7. GROUND LIFT: Disconnects pin-1 at the XLR outputs to eliminate
hum and buzz caused by ground loops.
8. BOOKENDDESIGN:Outerwrappercreatesa protective zone around
switchesandcontrols.Allsteelconstructionand bakedenamelfinish for
maximum strength, durability and years of trouble free performance.
9. POWER: Turns the Phazer on and off. LED illuminates when the
Phazer is active. It’s recommended the Phazer be turned off before
connecting or disconnecting cables.
10. 15VDC PSU JACK: Connection for the included Radial AC power
adaptor. Do not substitute for another power supply.
11. ¼” PHONE JACKS: +4dB balanced or -10dB unbalanced line-level
input and output.
12. XLRJACKS:+4dBbalancedline-level input and output.AESstandard
pin-2 hot. Male and female connectors.
13. FULLBOTTOMPAD:No-slipbottompad - reduces slipping inuseand
provides mechanical and electrical isolation.

QUICK START OPERATORS INSTRUCTIONS
The Radial Phazer™ is an analogue phase correction device designed
to time-align two signals so that the fundamental frequency of both
signals play at the same time. Before connecting, turn your sound
system OFF. Connect the supplied 15VDC power supply and turn the
Phazer on.
CONNECTING THE PHAZER. There are two ways you can connect
the Phazer, via the console insert points or in-line. This is done by
connecting a ¼” TRS insert cable to the insert points on the mixing
console or by connecting the Phazer in-line using the +4dB XLR
connectors from a mic preamp output to the line level input of your
console or DAW. If you encounter noise, try lifting the ground switch.
USING THE PHAZER.
The concept is simple: when using two microphones on an instrument
the sound will be captured by the nearest microphone first followed by
the more distant mic a few milliseconds later. When the mic signals are
mixed together the minute delay between the signals will cause phase
cancellation and produce a hollow weak sound.
This also happens when using a direct box and a microphone. The direct
box signal arrives instantaneously, while the microphone signal arrives a
fraction of a second later.
By inserting the Phazer into the signal path of the near microphone or
direct box, you can compensate for the time delay and phase-align the
near mic signal with the distant mic.
Start by setting up both microphones in the room. Listen to each mic
separatelyandpositionthem where theysoundbest.Insertthe Phazer into
the signal path of the nearest mic (or the direct box if your using one).
Set the PHASE and FILTER sections to bypass (LED is not illuminated).
Set the PHASE control to 8 o’clock (full counter-clockwise).
Mix both mic signals together and listen to the result. Engage the PHASE
section (LED is illuminated) and slowly turn the control clockwise as you
listentothe mixofbothsignals. Mostoftheaudible effectwill occur between
8 and 11 o’clock due to the energy in the low frequency band. For fun,
try reversing the polarity by hitting the SHIFT switch. This will toggle the
phasing effect from 0º~180º to 181º to 360º.
The FILTER section is a completely independent low pass filter that can
be used alone or with the PHASE section. Before you use the filter, turn
the FILTER control to 5 o’clock (full clockwise) and set the RANGE switch
to its outward position.
TheFILTERsectionisdesignedtoremovehighfrequenciesfromthenear
mic signal so that you can combine the fundamentals of the two sources
in the more audible bass region. Two cut-off ranges are offered. Engage
theFILTERandslowlyturnthecontrolcounter-clockwise while listening to
the effect. Only through experimentation will you begin to fully understand
the possibilities. Use your ears and have fun!
