Our ears receive vastly more information than we canactually perceive. All senses are filtered this way, andbring conscious awareness of only a tiny fraction of
the data registered by the body. Hearing is our mostprecise sense, timing-wise, involving substantial“pre-processing” in the brainstem and several
reflexes ahead of conscious recognition.
The outer ears are sophisticated entry points that areneeded to identify the direction from which sounds

arrive, but we’re not just carrying around two very
personal, directional microphones. Our ears and brain
work together in a continuous feedback loop with anabundance of nerve impulses going back and forth tofine-tune reception in the middle and inner ear, overa range of 60 dB. We also use head movements toreach out for detail, such as discriminating between
direct sound and reflections in a room, and thebrain’s left/right ear comparisons rely on the mostenergy-consuming nerve synapses of the body.

Therefore, only a trained listener can perceive thefiner nuances of auditory sensation. Musicians andaudio professionals learn to attain a heightenedawareness of imaging, pitch, spectral balance,transients and other qualities. The acuity of a trained
listener cannot be overestimated, and that is the typeof user for which THE ONES have been designed.

The positioning of microphones, where even minute
movements can make a difference, is a critical aspectof recording. Microphone placement, understandably,
is based on listening, which in turn requires an equalamount of accuracy from the studio monitoring
system. Mixing and mastering are other critical phases
where being able to entirely trust what you hear isessential for the outcome – including how well content
translates to other rooms and playback conditions.
Traditional studio monitors utilise displaced drivers
that generate coloured reflections – forcing a criticallistener to sit in one fixed position without moving,
and therefore the point source principle has long been
regarded as the holy grail of monitor design. However,previously attempts came with disadvantages;
including limited frequency range, distortion, unevendispersion or inadequate SPL, to name just a few.
THE ONES are uncompromised three-way point
source monitors whose dispersion is tightly
controlled in both planes, thanks to large, integrated
waveguides. They not only promote faster and moreconsistent production decision making, but also

allow longer listening times than a traditional monitor– because unnatural imaging, a main contributor
to listener fatigue, is minimised. For demanding
applications calling for ultra-nearfield to mediumdistance listening, precision imaging and long,fatigue-free working hours, these three-way
monitors are in an elite league of their own.

The frequency response of all monitors will change
depending on their placement in a room, and therefore
each needs to be aligned and calibrated after
positioning to ensure reliable listening conditions.
Genelec monitors have always featured manual EQ
switches to compensate for placement, but THE ONES
enable even more accurate automated compensation,
allowing reference listening under previously intolerable
conditions.
Using GLM™ (Genelec Loudspeaker Manager)
software, Genelec smart active monitoring systems
such as THE ONES can be easily installed, calibrated
and managed, and the same monitors may even be
used in more than one setup. In the GLM configuration
pictured, you can switch between six calibrated setups:
Mono, stereo, 5.1, 7.1, 7.1.2 and 7.1.4. When working
in stereo, simply switch between multiple nearfield
and main monitors using the same physical twochannel output from a workstation. GLM supports all
reproduction systems, even those witha very high monitor and subwoofer count.
Drawn from decades’ worth of data gathered fromthousands of studios, the GLM application quicklyaligns the level, distance and frequency response of
all monitors on the network; ensuring that setups work
reliably and in compliance with the latest standards,
independently of any external processing.
Moving beyond nearfield listening, a major challenge
in reference monitoring is to obtain a low frequency
response without pronounced peaks and dips,
particularly with systems not built into a studio’s walls.
GLM integrates closely with the new W371 Adaptive
Woofer System to make such concerns a thing of thepast, by creating free-standing monitoring systems
uncompromised by LF colouration.

9THE ONES offer precision monitoring with excellent
translation at all listening distances, from just 50 cm up
to several metres - enabling uncompromised monitoringeven in acoustically challenging studios. From ultranearfield stereo monitoring in small rooms, with head
movements preserved and room sound excluded, to largescale immersive setups, THE ONES family provides a fully
scalable solution for a huge range of room sizes, listening
distances and SPL requirements.
From music recording to mastering to post production, youreally don’t know how good your room can sound until you
have experienced THE ONES’ unique combination of neutral
direct sound and controlled acoustic room reflections;
qualities simply not obtainable from traditional monitors.
The W371 Adaptive Woofer System features two
independent woofers in acoustically different physicallocations within the room, and unlike traditional systems,
both units overlap in their range of operation. THE ONES
monitors can work with the W371 as a single full-range
system, with the W371 offering three different operating
modes to yield a choice of either flat and neutral LF
response avoiding room-induced peaks and notches
plus increased maximum SPL, or continued directivity ofthe main monitor down to the lowest LF frequencies, or
reduction of detrimental reflections by the walls, ceilingor floor. After selecting the monitor locations, each W371
uses GLM’s AutoCal function to pick and tune the signal
processing for the best LF radiation mode, taking into
account the monitor location and listening position.
The horizontal and vertical directivity plots on the next
pages demonstrate that sound radiated into the room isneutral. This is difficult to convey completely by using justa few numbers, and impossible to truly understand without
experiencing it for yourself!

Level

Frequency (Hz)The Complementary Mode can circumvent any reduction in soundlevel at certain frequencies (known as ‘acoustic notching’) at thelistening location, by placing the two independent woofers within
the W371 at different physical locations in the room - and by thenusing the woofer that is best able to radiate audio to the listening
location. In addition, GLM also equalises the W371 with The Onesfor neutral audio, delivering uncoloured low frequency sound withgreat dynamics.

Frequency (Hz)The Continued Directivity Mode uses the two woofers in theW371 simultaneously, to generate constant directivity whichmatches that of The Ones monitor being used with the W371.
This creates a four-way monitoring system that has continued
directivity on the horizontal plane right down to the lowest
audible bass frequencies.

The Anti-reflection Mode uses the two woofers in the W371
simultaneously to generate regions of silence (known as ‘nulls’) in
certain orientations. These nulls reduce the levels of reflectedaudio in the operating frequency range of the W371 caused byvarious surfaces in the listening room. This also reduces theacoustic coupling of low frequency energy into room reverberation,
thus reducing any detrimental effects of the room’s acoustics.
