Le lecteur SACD multi-sources English description at the end Le MP 2500 R est le plus récent et le plus sophistiqué des lecteurs multi-sources et PCM / DSD DAC série R.  Le MP 2500 R est construit conceptuellement et technologiquement comme le MP 2000 R MKII. Les deux appareils sont spécialement conçus pour la lecture sans compromis de données audio haute résolution. Au lieu d'un lecteur de CD, nous avons équipé le MP 2500 R de notre tout nouveau lecteur SACD du SACD MP 3100 HV haut de gamme. Comme dans le MP 2000 R, nous utilisons notre convertisseur quadruple différentiel double supérieur avec traitement de tous les signaux numériques pour convertir les données PCM. Pour les données DSD, le convertisseur DSD analogique 1 bit T + A True unique est utilisé, qui ne convertit pas les données DSD mais les traite nativement en flux binaire. Cela signifie que même les données DSD jusqu'au DSD 512 provenant de l'entrée USB du tableau de connexion numérique peuvent être reproduites avec la meilleure qualité. En tant que client de streaming, le député a 2 500 R obtenir le T + un conseil en continu de haute résolution, qui permet non seulement la plus haute résolution, mais aussi l'utilisation de différents services de musique, radio Internet et la connexion au réseau domestique via LAN et WLAN, le mode maître USB et streaming HD à partir de serveurs de réseau.L'excellent accordeur sonore est compatible FM, FM-HD et DAB +. Un module de diffusion Bluetooth de haute qualité pour la transmission de musique depuis des appareils mobiles est également installé. Le fonctionnement du PM 2500 R, ou même un système R ensemble, via le FM1000 de commande à distance infrarouge ou au mieux sur l'application de contrôle T + A. Cela a servi, par opposition aux applications de nombreux autres fabricants, notre équipement est complet dans toutes les fonctions et montre non seulement les informations du client de streaming, mais aussi le contenu d'affichage de toutes les sources, telles que le nom de la station et le texte de la radio lors de l'opération FM. En option, la télécommande bidirectionnelle FD 100 peut être utilisée. Il ne représente pas seulement l'affichage de l'appareil, mais couvre également l'art. lecteur SACD drive Précision entraînement linéaire. Système laser double: SACD: 650 nm, CD: 785 nm formats SACD Stéréo, CD / DA, CD-R, CD-RW, SACD / CD Text Réponse en fréquence et dynamique SACD: 2 Hz - 44 kHz / 110 dB, CD: 2 Hz - 20 kHz / 100 dB Streaming client formats MP3, WMA, AAC, OGG Vorbis, FLAC, WAV, AIFF, ALAC débits de données PCM 32... 192 kHz, 16/24 bit; MP3 jusqu'à 320 kbits, débit constant et variable traits Lecture Gapless pour MP3 (Lame), WAV, FLAC T + Une application de contrôle pour iOS et Android normes Contrôle UPnP AV, T + A services: Tidal, Deezer, qobuz (abonnement requis) interfaces LAN: Fast Ethernet 10/100 Base-T, WLAN: 802.11 b / g / n Tableau de connexion numérique Entrées numériques S / P-DIF 1x AES-EBU, 1x coaxial, 2x BNC, 2x TOS-Link USB (mode périphérique) 1x mode périphérique USB asynchrone USB (mode maître) 2 x mode maître USB pour le stockage de masse USB Tuner FM norme de réception: FM, FM-HD gamme de fréquences: 87,5-108 MHz; sensibilité (> 65 dBA S / N) 1 μV Headroom: 103 dB uV THD: 0,1% Signal / bruit distance mono / stéréo 72/62 dB séparation stéréo 50 dB Deemphasis (version Europe / États-Unis) 50/75 nous services de données:RDS / RDBS, nom de la station (PS), type de programme (PTY), texte radio (RT) Tuner DAB norme de réception DAB, DAB + gamme de fréquences 168-240 MHz (Volume III) Sensibilité (BER = 10 - 4) 2,0 μV Headroom 103 dB uV Bluetooth A2DP (audio), AVRCP 1.4 (contrôle) / aptX®, MP3, SBC liens Sorties analogiques haut niveau (RCA):2,5 Vrms / 50 ohms Sortie analogique symétrique (XLR):5.0 Vrms / 50 ohms Sorties numériques:1 x coaxial, IEC 60958 S / P-DIF (LPCM) Convertisseur N / A PCM quad différentiel double convertisseur avec 4 convertisseurs N / A par canal, 32 bits Delta Sigma, 352,8 KSPS / 384 KSPS DSD Convertisseur N / A DSD T + A-True-1Bit jusqu'à DSD 512 (22 MHz) Réponse en fréquence PCM 44,1 kSps 2 Hz - 20 kHz Réponse en fréquence PCM 48 ksps / dsd 64 2 Hz - 22 kHz / 2 Hz - 44 kHz Réponse en fréquence PCM 96 kSps / DSD 128 2 Hz - 40 kHz / 2 Hz - 60 kHz Réponse en fréquence PCM 192 kSps / DSD 256 2 Hz - 80 kHz / 2 Hz - 80 kHz Réponse en fréquence PCM 384 kSps / DSD 512 2 Hz - 100 kHz / 2 Hz - 100 kHz filtre analogique Filtre Bessel linéaire symétrique, phase 3, 100 kHz THD Signal to Noise Ratio 116 dB la séparation des canaux 110 dB Connexion / Accessoires / Dimensions Interface de contrôle R2-Link contrôle à distance FM 1000, T + A Control APP, télécommande d'affichage optionnelle FD 100 raccordement au secteur:100-240 V, 50-60 Hz Consommation électrique max.:40 watts Eco veille:0,3 watts fonction de mise hors tension automatiqueoui (après 90 minutes sans signal audio) Dimensions (H × W × D):16,5 × 46 × 40 cm poids: 11,3 kg T+A MP-2500R Media Player SACD/CD/DAC/Streamer/Radio The Multi Source SACD Player The MP 2500 R is T+A's newest and most sophisticated Multi Source Player and PCM / DSD DAC in the R-Series. The MP 2500 R has the same overall design philosophy and technical facilities like the smaller MP 2000 R MK II player. Both have been developed to reproduce high-res audio files without any trace of compromise. Instead of a CD mechanism T+A have equipped the MP 2500 R with the SACD drive from T+A's High-End SACD player MP 3100 HV which is a completely new development.  As in the MP 2000 R MK II, PCM data is converted using T+A's outstanding double differential quadruple converter with all it‘s sophisticated digital signal processing. DSD data are handled by the unique analogue T+A true 1-bit DSD converter from the PDP 3000 HV, which processes the DSD data in native form as a bitstream rather than converting them. This makes it possible to reproduce DSD data up to DSD 512, as delivered by the USB input of the digital connecting board, to the highest level of quality.  The machine’s streaming client takes the form of the new T+A high-res streaming board, which provides maximum resolution as well as the facility to access various music services, Internet radio, inclusion in the home network via LAN and WLAN, USB Master Mode and HD streaming from network servers. The digital tuner offers FM, FM-HD and DAB+ capability, and delivers excellent sound. The T+A MP 2500 R also includes a high-quality Bluetooth streaming module for transferring music from mobile devices.  The machine is controlled using the FM1000 infra-red remote control handset, or – ideally – the T+A Music Navigator App. In contrast to many manufacturers’ Apps, this is capable of controlling every element of every function of T+A's machines. Not only does it display the information pertaining to the streaming client, but also the screen content of all sources, such as the station name and radio text when used in FM radio mode. As an option the FD 100 bi-directional RF remote control system can be used as well. It displays the full content of the device screen and coverart as well. Technology It is only natural that the SACD and CD continue to lose significance, as they are increasingly superseded by streamed content; a trend reflected very clearly in the huge success of T+A's multi-source players with their extensive streaming facilities. However, it is clear that T+A audiophile customers still wish to be able to play music from CD and SACD, because none of us wants to throw away our old collection, and in any case there is an undeniable charm in owning a tangible data medium. Infact the SACD is currently experiencing what we can only term a renaissance all over the world. Therefore T+A decided to develop a completely new, modern SACD mechanism incorporating the latest decoder technology, offering very short access times and outstanding error correction. It is capable of reading CD (PCM 44.1 kSps) and SACD (DSD 64 2.8 MHz) discs at the highest possible quality. T+A have invested a huge amount of effort in the mechanical design of the drive unit, incorporating a high-quality drive, double laser optics and heavy-duty motors. With the aim of eliminating all traces of interaction between the moving parts of the disc drive and the remainder of the player T+A's disc mechanism features a mechanical isolation. A heavy aluminium plate and a solid case, which act as a mass damping devices, thereby preventing any structural sound from the mounting surface finding its way to the electronics and the disc mechanism. The disc drawer runs on two accurately machined stainless steel pushrods, while the disc rests in a specially coated, high-quality ABS cradle.

Micro testé et marche bien. L'AKG D-109 est un microphone omnidirectionnel de haute qualité qui a été conçu électroacoustiquement pour des performances optimales lorsqu'il est porté monté sur une cravate. Instrument compact et léger, le D-109 associe une reproduction vocale précise à une apparence discrète. Le D-109 est également fortement recommandé pour une utilisation «mains libres» dans les églises, les écoles, les amphithéâtres et les salles de conférence. Contrairement à un microphone conventionnel (qui exagère les basses fréquences et atténue les hautes fréquences lorsqu'il est «adapté» pour une utilisation en cravate). le D-109 a une réponse en fréquence spécialement profilée qui lui permet de fournir une reproduction de la parole naturellement équilibrée lorsqu'il est placé contre la poitrine de l'utilisateur: la réponse est intentionnellement réduite en dessous de 300 Hz pour réduire la coloration tonale causée par la résonance de la cavité thoracique. De plus, avec le clip cravate en forme d'anneau relevé complètement au-dessus du niveau de la grille du microphone, la réponse est amplifiée entre 2 kHz et 6 kHz pour compenser à la fois l'absence de propagation haute fréquence sous le menton et l'effet de filtrage des vêtements qui peut être utilisé pour dissimuler le microphone. (Le pic à 6 k Hz peut être réduit selon les besoins en abaissant le clip cravate, comme indiqué dans les courbes de réponse en fréquence ci-dessous.) La grille en treillis métallique du D-109 et son boîtier en laiton robuste encapsulent efficacement l'élément transducteur contre les particules métalliques et la poussière. Microphone tested and working well. The AKG D-109 is a high-qual ity omnidirectional microphone that has been electroacoustically designed for optimum performance when worn lavalier-mounted. A compact and lightweight instrument, the D-109 combines accurate speech reproduction with unobtrusive appearance. The D-109 is also highly recommended for "hands-free" use in churches, schools, lecture halls, and conference rooms. Unlike a conventional microphone (which exaggerates low frequencies and muffles high frequencies when "adapted" for lavalier use). the D-l09 has a specially contoured frequency response that enables it to provide naturally balanced speech reproduction when placed against the user's chest: Response is intentionalLy rolled off below 300 Hz to reduce tonal coloration caused by chest-cavity resonance. Furthermore, with the ring-shaped lavalier clip raised fully above the level of the microphone grille, response is boosted between 2 kHz and 6 kHz to compensate both for the lack of high-frequency propagation below the chin and for the filtering effect of clothing that may be used to conceal the microphone. (The peak at 6 k Hz may be reduced as required sirnply by lowering the lavalier clip, as shown in the frequency-response curves below.) The D·109's wire-mesh grille and rugged brass case effectively encapsulate the transducer element against metal particles and dust.

SENNHEISER PXC 450 HEADPHONES - REDUCED TO CLEAR The PXC 450 is a circumaural high-end travel headphone set with NoiseGard™ 2.0 technology and TalkThrough function for the best possible attenuation of ambient noise. The PXC 450 enables an unprecedented sound experience for people on the move, thanks to its adaptive baffle damping in combination with the patented Duofol diaphragms, which prevent unwanted partial oscillation and thus guarantee a highly natural, lifelike sound quality. NoiseGard™ is an active noise compensation system which Sennheiser originally developed for use by pilots, who have to rely on good sound quality and efficient protection against ambient noise even in high-noise environments. NoiseGard™ actively compensates the noise, based on the physics principle of sound and counter-sound. NoiseGard™ 2.0 has perfected the NoiseGard™ principle thanks to the use of optimised circuitry design and even more efficient processors. It also uses better quality microphones, which enable more sophisticated pick-up of unwanted noise. Specially developed filter algorithms enable improved active noise compensation of up to 90% (23 dB). It is of course also possible to use these headphones passively, i.e. without NoiseGard™ and without batteries.  Users of a PXC 450 who wish to communicate with their neighbours can do so without taking off the headphones: when the TalkThrough function is activated, professional quality microphones mounted on the outside of the headphones pick up all acoustic signals in the immediate vicinity. Unwanted background noise, such as the sound of the engines on a plane, is filtered out electronically to a great extent, so that only the neighbour’s voice is passed on through the headphones into the user’s ear in top audio quality. The PXC 450 is foldable and is supplied complete with practical transport case, 2 AAA batteries and audio adaptors (double mono and 6.3mm). Volume control integrated in the headphones and a single-sided detachable and replaceable cable ensure maximum convenience for the user. SPECIFICATIONS: Colour: Silver Wearing Style: Headband Impedance: 150/750 ohms Connector: 3.5mm right-angled Frequency Response: 8 - 2800 Hz Sound Pressure Level: 108 dB Total Harmonic Distortion: Ear Coupling: Circumaural Cable Length: 1.4m single-sided, replaceable Transducer Principle: Dynamic Weight: 240g Attenuation: Passive - 32 dB Operating Time: > 21h Battery Specification: 1 x AAA Battery NoiseGard Noise Compensation: Up to 23dB (NG 2.0)
