Touring Logitech's Audio HQ 

In searching for an ideal cellular gambling headset, I just expressed my own total dissatisfaction together with available choices. Actually today’s best cellular products continue being significantly flawed by a number troubles which range from sub-par audio faithfulness, an inadequate mike as well as cart firmware.

Shortly after in which distribution, Logitech reached available to people for the tour of their audio headquarters inside Camas, Buenos aires. Possessing discovered the actual scarcity associated with excellent cellular gambling headphones, 
Logitech used a final 1 . 5 years planning just what the idea feels to become the top title of,
 most well-featured headset available, gambling or otherwise. Actually, Logitech is indeed assured inside the Artemis Variety, the idea fearlessly (foolishly? ) used it is design into a modest wrap up associated with hesitant technology journalists assured they will go house pleased. Ballsy.






The particular Artemis Range is actually timetabled to arrive in Q3 2015 in a couple types: G633 (wired) and G933 (wireless). The particular G633 really should basically appear this thirty days. Both equally headsets feature a tailor made audio tracks driver in which provides high-end sound, retractable noise-cancelling microphones, multi-platform service and several great features.

Logitech wishes to write off the idea in which games headsets (wireless especially) cannot likewise gratify critical audiophiles. It really is apparent in which a lot of considered, architectural and style was place into the particular Artemis Range and therefore, it's going to be advertised as being a top quality, high-end merchandise.



"We discovered that no one really was making a set of high quality headsets regarding gamers, thus many of us challenged your sound recording crew to determine whenever they could do it. I’m some sort of game addict and a music performer, well, i really was ecstatic when the crew delivered with a design that shipped. " -- Ujesh Desai, Logitech Grams VP along with GM
Without a doubt, this Artemis Spectrum can be driven.

 Does the inventors along with ladies with Logitech actually supply? Your original judgement: encouraging. We are going to end up in additional information about the Artemis Spectrum in a very touch, although primary... in with all the tour!


Logitech G Vice President and General Manager Ujesh Desai

The Tour Begins

We arrived in Camas, Washington bright and early. Cutting the ribbon in 2010, Logitech’s audio headquarters in Camas is 40,000 square feet and houses roughly 100 employees. This is the facility where Logitech and subsidiary Ultimate Ears research, engineer and design many of its audio products.


Immediately after showing up inside Camas, Logitech G VP and Standard Administrator Ujesh Desai gave us the engaging presentation about the essential position audio tracks represents inside online games. Until finally this kind of minute, the actual concentration of our own go to (i. electronic. Artemis Spectrum) had been held within tight wraps. Incidentally, our dissatisfaction along with instant headsets seemed to speak out loud along with Ujesh. Some quotes have been lent coming from our instant headset roundup to be able to focus on the actual unfortunate express associated with instant gaming headsets writ significant.





Details of the Artemis Spectrum finally emerge! The G633 will be wired and the G933 will be wireless. Some noteworthy features include fully customizable RGB LED lighting, extremely versatile multi-platform support, programmable macro buttons, DTS Headphone X 7.1 surround and Logitech's custom Pro-G audio driver designed to please even audiophiles.





Acoustical Systems Engineering Lab


Right after becoming presented on the Artemis Spectrum, most of us were separate right into a handful of little organizations as well as brought about in the various labs which will make the service.
Ahead of time, Mature Acoustical Programs Professional Tracy Wick exhibited people benchmark side by side somparisons connected with Logitech’s brand new Pro-G sound drivers vs their opposition. His / her enjoyment had been palpable. Surely, if there were one thing to consider home from your expedition, it turned out in which everybody in Logitech is exceedingly like to show off the actual Artemis Spectrum.

The perfect loudspeaker operates being a piston: properly even. Logitech states their Pro-G transitions for you to substantial frequencies far more efficiently compared to contending drivers showing off typical materials diaphragms. This can be owing partially to your decide on mixture of mesh-woven diaphragm products. Despite the fact that these products aren’t little-known for you to Logitech, the organization states that Artemis Spectrum would be the primary headset for you to carry out such an sound drivers. The results will be high-end sound fit pertaining to audiophiles as well as players likewise.

Laser scanners, high-prescision osciliscopes and polarity testers are just some of many tools you'll find in Logitech's audio engineering department. Some of the tools here cost north of several thousand dollars.



The Anechoic Chamber

In order to effectively test it is sound recording items with out coloring through echo/reverb, Logitech created precisely what is called the anechoic chamber. Probably the most amazing halt with our visit, this specific specially-designed space posseses an impressive background noises bottom involving “approximately 0 dB”. To put it differently, it's actually a higher level of silent you could have very likely certainly not encountered. Actually, this absence of noise can be so serious in which a number of people obtain the combined noiselessness along with springy bottom nauseating.







This anechoic appropriate slot is totally ornamented by means of noise supressing wedges testing 4 feet deeply. This “floor” is really insert fine mesh dangling previously mentioned far more wedges. This target is to supply CAPS with all the purest possible noise possibly be eliminating most demonstrates and also vibrations that may colour noise.

 The exterior walls on this bedroom usually do not hint surrounding creating making it properly its creating. Logitech spent roughly $1, 000, 000 about a couple semis really worth connected with materials to develop that bedroom.

From the Materials and Executive lab, Merchandise and Style Boss Doug Sharpened explained the majority of the issues throughout choosing the best products while in unison achieving yourwants connected with fitters. The good news is, equally fitters and makers have been in the identical center aiding facilitate the dialogues over form as opposed to functionality.






Doug shows off the Artemis Spectrum’s RGB lighting on a transparent prototype. The Artemis features removable, magnetic side panels which can be replaced with customized ones. Logitech plans to release schematics so owners with 3D printers can print their own decorative panels at home.

EE Testing and Compliance Lab & Semi-Anechoic Immunity Chamber

While the anechoic chamber deals with sound waves, the semi-anechoic immunity chamber focuses on higher radio frequencies. The primary function of this room is validating for FCC compliance. The chamber is lined with wave-dampening absorbers. Unlike the anechoic chamber however, foamy spike-looking dampeners are narrower in shape and can be reconfigured for different wavelengths.

An adjacent lab tests the effects of ESD (electrostatic discharge) on each device being designed. All aspects of design are important, but ESD compliance is non-negotiable. Interestingly, designing for ESD robustness often impacts the look, shape and features of a device during even its earliest stages.

RF Performance Testing

Your next stop had been a lab which usually exams the particular RF/wireless functionality involving products much like the Artemis Variety G933. One particular important objective would be to guarantee instant headsets broadcast RF impulses since symmetrically as well as evenly as you possibly can. For the reason that position in the consumer pertaining to the particular transmitter is actually adjustable, insurance must be both equally powerful in all directions.

Microwave kitchen appliances are classified as the scourge involving two. 4GHz. One particular professional recounted a scenario where they will discovered a number of microwaves expected a certain volume of drinking water to get existing just before they might achieve their own maximum result. One amongst a lot of specifics to take into account whenever tests RF.

Interestingly (and perhaps surprisingly) the G933 will operate exclusively within the 2.4GHz band. Although 5GHz is often considered cleaner, Logitech is firm in its choice. The company said its channel hopping techniques and antenna sensitivity have been significantly improved since the the G930 appeared. Additionally, their updated 2.4GHz Avnera chipset consumes less power, offers lower latency and provides better range than the 5GHz implementations they’ve tried. Logitech also argued that 5GHz offers zero benefits -- they simply don’t need it because 2.4GHz already provides everything the G933 needs.

LGS Software and Logitech Signature Studio

Next, we took a trip back to the demo room. Logitech’s software lead was eager to show off some upcoming LGS (Logitech Gaming Software) features. Artemis Spectrum will be highly configurable through LGS with macros, customizable lighting (e.g. breathing, coloring, enabling/disabling certain LEDs) and loading your favorite settings into firmware so you can enjoy them without LGS. Uniformly setting LED colors/styles across all of your Logitech devices in a couple clicks is just one of the cool things owners can expect.
As a side note, the gaming demo stations were Origin PCs armed with Logitech G910 keyboards and G300s mice. By the way, I really liked the Romer-G switches on the G910. I actually enjoyed typing on it more than the Cherry MX Browns I typically use.
A number of demo stations were set up to showcase the various features of the Artemis Spectrum: LGS, surround capabilities, multi-source audio playback were just a few.
The last stop on our tour, the Logitech Signature Studio, is what your home theater might sound like if you had lots of disposable income. It's built to be both comfortable and sound as neutral as possible. The sound setup here was amazing and this is actually where we had our DTS Headphone X demo.
DTS Headphone X is a potentially significant component to the Artemis Spectrum experience. As I will describe later, it was by far the most convincing surround experience I've had on a headset.
Next up, our first look at the Artemis Spectrum G633 and G933 headsets.
