No compromise,ever

Rob Swire, Pendulum

The culmination of PSI Audio stereo development is the Master A25-225 system consistingof a pair of A25-M speakers extended with apair of A225-M subwoofers.
The crossover frequencies between the units
are perfectly aligned and form a flat frequency
response from 24 Hz up to 23 kHz. This systemcomes with all the technology of the single
units (CPR and AOI), but provides an increased
frequency range and SPL. It can also be usedas the basis of the most powerful PSI Audio 5.1
surround sound system.

SUBWOOFERS(LFE)

There is no point emitting low frequencies if
not precise, tight and controlled. Unfortunately
most subwoofers simply emit uncontrolled low
frequency that might be impressive but does
not resemble the input signal in any way.
The development of our subwoofers is based on
the same technology we use in our loudspeakers
so that it acts as a real low frequency extension
and the musical instruments can be clearlyrecognised down to the lowest frequencies.
If you are looking for tight and accurate low
end, which adds an additional voice to yoursetup, you will want to listen to the A125-M
or A225-M and change your mind about
subwoofers.
Most common remarks heard when people
listen to PSI Audio subwoofers: “It sounds sonatural” or “The low end is so precise I canfinally distinguish the bass from the kick”.

Exceptional pieces of acoustic design, the A125-M and A225-M subwoofers/bass extension are equally suited
to use as a mono subwoofer (LFE) in a surround sound application or as a bass extension in a stereo system.
The A125-M and A225-M are designed to work in harmony with the entire range of PSI Audio speakers.
Our monitors all feature a frequency response roll-off function that, when combined with any of the subwoofers,
extends the frequency range down to 24 Hz, whilst maintaining a perfectly flat response.
To provide stability and avoid cabinet resonance, A125-M and A225-M are built with a double-box design,
combining two cabinets into a single beautifully finished unit.

The AVAA absorbs low frequencies like a hole in the wall

THE PAIN• Low frequency is extremely difficult to absorb 		
with passive systems• In most rooms many modes occur below 200 Hz• Room modes resonate far longer than otherfrequencies, clouding the mids and highs• The pressure of room modes differs significantly
from one location to another• The vast majority of rooms are well treated for
medium and high frequencies but have very
disturbing room modes
THE AVAA• Actively absorbs low frequencies from 15 Hz 		
to 150 Hz, 5 to over 20 times more efficiently thana perfect passive absorber of the same size
• Works in any room (recording, control, listening)• No sound emitted• No calibration or settings required• Can be turned ON and OFF to highlight the effect• Small footprint and can easily be moved from 		room to room
• 100% analogue, no DSP, no latency• An acoustic solution to solve acoustic problems

“It’s amazing the precision,
beauty, tightness and controlof the bass in my masteringroom, thanks to PSI Audio”

Revolutionary
activebass trap

Bob Katz

The frontier to your bass problems.
Having a perfect source of sound is paramount but the characteristics of the room the speakers are used inare also very important. Although it is quite easy to control the mid and high frequency response in a room,
the low frequencies are very difficult to absorb and are the most disturbing room modes.
We have been thinking about using the advantages of our unique active technology to control low frequencies
for decades and spared no effort in finally developing the first ever Active Velocity Acoustic Absorber (AVAA).
This revolutionary product is the only efficient and broadband solution to low frequency room modes!

12

The AVAA can be more effective than a perfect absorber of thesame size by affecting the acoustic impedance around it.

www.psiaudio.swiss© Mary Kent

Equivalent absorbing area of one AVAA depending on thefrequency. The AVAA has a surface of 0.2 m 2 so an equivalent
absorption area of 4 m 2 is 20 times more effective than aperfect absorber the size of the device!

YOUR GAIN• Significantly reduces low frequency room modes
reverberation time
• Better defined mid and high frequencies throughreduced masking effect• No alteration of the direct sound• Better defined stereo image with less indirect sound• Smoother frequency response in the entire room
• Room sounds more natural• You can work with better definition and more 		
confidence

DESIGN & TECHNOLOGY
ACCURATE SOUND IS NATURAL SOUND
A monitor’s mission is to transform an electric signal into an acoustic signal.
It should do so as accurately as possible to reproduce in detail all the richness of the original sound.
This is the only way to recreate the original emotions.

CREATE, MEASURE, LISTEN, REPEAT...
Some parameters are easy to measure and very
difficult to hear, while other sound characteristics
are easy to hear and perceive but impossible
to measure.
As professional loudspeaker designers andmanufacturers it is our role to be objective
as can be and use all the tools and informationthat may help.
Laboratory measurement in specific conditions(such as a certified anechoic room) can beconsidered as objective, and should be used
to validate and track progress as well as tocontrol and calibrate production.
Listening sessions are more important but
much less objective. Therefore they need tobe performed by a number of specialists indifferent environments and follow a defined
protocol. We typically use a panel of selected
specialists including sound engineers,
golden ears (Tonmeister), musicians, and othereducated ears, all listening to a wide rangeof sound samples.
All our developments, including the slightestchange in component or design, are rigorously
evaluated by measurements and listening
sessions and more measurements and further
listening in order to ensure the objective
quality of our sound reproduction.
The most satisfying comments we get are frommusicians who live their emotions over again:“I cannot only hear the instrument perfectly,
I can clearly recognize my own instrument in
the room it was recorded in”.
This is what our know-how and technology
achieves.

18

A PERFECTLY INTEGRATED SYSTEM
Cabinet, membrane, amplifier are designed towork as a system
We developed a superbly integrated system
where amplifier, driver, membrane and cabinet
all perfectly work together in space and timewith the laws of physics as the only limit.

100% PURE ANALOGUE TECHNOLOGY
Fast, linear, accurate, reliable, seamless
Ears are analogue. Sound is analogue. A transducer is analogue. Our loudspeaker technology
is also entirely analogue. This requires smart
design as well as the highest degree of quality
control over all components and manufacturingof the loudspeaker. Well-mastered analogue
technology guarantees fast, linear, seamlessand reliable functioning with no latency.

CLASS G/H AMPLIFIER
Most efficient with lowest distortion
All of our amplifiers are 100% designed andassembled in our facilities, ensuring the highest
possible degree of reliability and performance.
This is achieved through our class G/H amplifierthat combines the advantages of class AB
amplifiers with greater efficiency and lower
distortion.

www.psiaudio.swiss

COMPENSATED PHASE RESPONSE
Coherent and accurate phase response
Accurate sound reproduction requires not only
a flat frequency response, but also a linear
phase response. Our CPR system accuratelyaligns the phase response of the monitor toperfectly recreate the transients and space imageof the real sound.

ACOUSTIC LOAD GUIDE
Optimised wave guide
The shape and dimensions of the waveguideused in PSI Audio tweeters is specially designed
to optimise directivity as well as maximisingsound pressure level and extending bandwidth.

ADAPTED OUTPUT IMPEDANCE
Perfect impulse with no coloration
During the movement of the coil, the AOI
circuitry seamlessly adapts the amplifier’s
output impedance to ensure ideal accelerationof the membrane needed to reproduce thedesired impulse with no coloration whatsoever.

PHANTOM STANDBY CONTROL
Remote standby technology
This feature is extremely useful when switching
between monitoring configurations andvisualising if speakers are active or in standby
mode. It is best used with our R&B (router andbass management) footswitch that allows to
seamlessly switch between 3 different monitoring
configurations.

MANUFACTURING
A PERFECT SPEAKER IS THE SUM OF COUNTLESS PERFECT DETAILSPSI Audio products are handmade to ensure necessary attention to each and every detail.

20

CABINET MAKING
Cabinets are manufactured with great care andattention from the choice of the wood all theway through to the paintwork.

COMPONENT MATCHING
In a precision analogue device, it is paramountthat all components achieve the desired result
together. This requires matching of sensitive
components on each board, which is done bymeasuring them each individually.

TWEETER MANUFACTURING
The tweeter of the A25-M is entirely designed
and manufactured in our workshops to ensure
the tightest tolerances in all aspects. Winding,magnetization, gluing and mechanical positioning
using a microscope all need to be done by skilledhands to reach the record high SPL and low distortion required. A world record! The other transducers used are sourced from qualified suppliers
and according to our design and specifications.

INDIVIDUAL CALIBRATION IN LARGEANECHOIC CHAMBERAs the role of a monitor is to transform an electric
signal into an acoustic signal, every single
monitor produced is checked and calibrated
in our large anechoic chamber to ensure its
quality.

INCOMING INSPECTION
The outsourced components are all individuallychecked to ensure they are fit for use in a PSI
Audio monitor. This is necessary as our tolerances
are often far tighter than what the best suppliers
can guarantee.

BOARD ASSEMBLY
The board assembly and soldering is entirely
done by hand to ensure it is perfectly adapted,
and with the adequate temperature, for eachcomponent. It also allows continuous supervision
over the entire manufacturing process.

ASSEMBLY
Assembly is of course also done entirely byhand to ensure continuous quality supervision
over each and every detail of the manufacturing
process.

CALIBRATION CURVE – THE BIRTH CERTIFICATE
Like any respected precision instrument, eachof our monitors is issued with its own calibration
curve that can be considered as a real birthcertificate showing it is ready to leave the factoryand be used for many decades.

Since using my PSI Audio monitors, I havenoticed a significant increase in masters being
approved on the very first version. Decisions
are so easy to make and I don’t second guessthings anymore. In my old room, the A215-M
monitors didn’t require a subwoofer but since
my new room is larger, I decided to add a pairof A125-M subwoofers, in part for some low
frequency extension below 30Hz, but mainly
for the ability to listen louder than I needed tobefore since my new room is bigger. I recently
added some mid-level monitors from anothercompany for my home studio setup and it
was incredible to hear how unclear they arecompared to the PSI Audio sound I am used
to in that room. I will have to add another setof PSI Audio for the home setup now.

The AVAA Active Bass Traps are also amazing.
I know they can easily seem like voodoo or
snake oil but PSI Audio has done their researchand testing, and they are very effective for correcting low end issues in your room. They bring
the low end into focus in ways you didn’t think
were possible until you hear it in person andcompare with them turned on and off. They are
great for people like myself who are not acoustical wizards because you simply plug themin to a power source, try them in a few logicalplaces and pick what works best. No acousticalmeasurements or calibration required, justuse your ears. In my old room I had them on
the front wall but in my new room my listening
position is closer to the rear wall so they are
most effective there.
