Keywords: 5.1 surround sound equipment design
Note: the Straightforward People's Give a buzz routine Concert Antechamber by the ambition of 2004 ongoing the recording control opportunity of the restitution project like Stereo Recording control opportunity transformed into surround sound audio control room, presently the opportunity has been deposit into use. Was consistent pro Organization Implementation of the rebuilding project author surround sound recordings on the control opportunity pro process design, equipment selection, etc. were summarized consolidation is probable to implicate surround sound equipment to provide reference counterparts.
A Inhabitant Car phone arrangement Antechamber recording control opportunity is overall used to confirmation the leading stereo programs to happen versus the needs of surround sound recording program, and Taiwan inside the transformation of decision to Dig up on to Surround sound the foremost program, while brainwashing the recording compatible stereo control room.
Indication considerations Current 5.1 surround sound control opportunity inside lone of the few, very hardly a few can heap from indication data.
Our foremost consideration inside the indication of several areas:
1. Dexterity to ITU-R BS.775-1 standard pro the thought basis.
2. Acoustic sound control opportunity acoustic to approach con technical requirements, such equally reverberation compute RT60 = 0.3? .1 S (63Hz
3. Functions to: a generous orchestra pickup surround sound, multi-track recording, surround sound mixdown and mastering the production; recording a generous pipe organ work surround sound; inside the totality recording process pro all digital indicate storeroom break and processing; surround sound and stereo compatible, and the same curriculum and stereo surround sound things real-time comparison; real-time Watch The circumstances inside the Concert Hall, with well-located domestic interaction and interaction functions; recording control room, sound reinforcement room, master notebook place to stay and audio catalog to chat data linking the (analog and digital); by lifting the microphone, saloon floor microphone stomach and high-quality micro-capacitor microphone and stage large-scale symphony orchestra performances, recording results inside ensuring the premise of guaranteed performance visual effects; befall the engine opportunity of the file and audio signals sent to neighboring place to stay surround sound pre-trial examination conducted monitoring; to the engine opportunity of the file and audio indicate sent to watch the pitch and the concert antechamber monitor; multi-party teleconferencing; receiver Cable television Signal, and so on.
Based on the advanced than considerations, we like befall on bad provisos into the control room, the detailed logic inside and outside the control opportunity (the Hall-house) inside two parts.
Domestic Process Clue And how about the Multi-Pattern Condenser Microphone ?.
Antechamber Control opportunity outside of equipment idea process is on bad terms into two parts, thrilling box and microphone.
Electrical box idea process Concert Antechamber stage inside the front, midpoint and rear missing and right, all fit 3 to box, on bad terms into the dexterity supply box, back box and the microphone box to hurl a whole of 6 groups. All assemble has five microphone jacks, two power outlets and two-way box to hurl back output. A further apron with lone feature furthermore the AV outlet box to provide outdoor playback and square Box signals Studio Studio monitor, so you can replay the concert antechamber to the sound source and the remote television arrangement meeting.
Microphone idea top Concert Antechamber stage and lynching domestic microphone into two parts, you can furthermore add a wireless microphone equally needed.
(1) lynching microphone part of the
Taking into tab the lengthy distance transmission lynching microphone indicate by the venue Easy , A better power supply and other factors, it want befall lynching ceiling microphone to the microphone trail metal tube closed, and befall well grounded, to lessen the interference. The same time, the microphone Amplifiers Approximately stirred to the roof, the microphone want choose up the weak indicate inside situ amplification and encoded into a digital multi-channel series morsel spill (ie MADI signal), by two 75 inside Coaxial cable Return the control room.
MADI coaxial cable indicate opinion of transmission distance 50m, 40m part of the line in fact thrown around, ensure the lynching microphone indicate transmission quality. The microphone box MADI cable can befall the continue of its 56-channel mixer on a microphone channel to transmit control signals to realize the level of the microphone, remote control interface and phantom power. Lifting the microphone top performance according to the present symphony orchestra seats spots. To come across the matter-of-fact needs of the uncommon microphone pickup, the belt lynching inside front of a row of cardioid directional microphone, equally the standard of the foremost microphone pickup AB; Inside addition, the popular conductor DECCA tree lynching behind the microphone arrays; furthermore prepared a ATMOS5.1 surround sound microphone, surround sound equally a single top of pickup to add.
Map 1 stage and the location of microphone holders lynching layout
Standard microphone using the idea AB, primarily taking into tab the standard AB stereo recording inside a significance of degree of respect and integration advantages of relatively prominent.
Keep the idea of AB system, microphone, on the lone furnish you can take up again to keep up the advantages of tape recording of AB system; the other hand, a types of recording formats inside the fabric, you can befall added equally the foremost and supporting microphone. DECCA DECCA Tree microphone array is the company's proven, were all highly popular recordings pickup standard, has been Expert They focus of the study, inside its primitive organize of T-derived types of recording formats, selected according to the real situation. The lynching of the foremost microphone while still using T-rack receiver rack, but is uncommon inside with the intention of rack installed six microphones: the forefront of MS logic is a duo of stereo microphone, visage the stage panoramic pick; from two 0.5m feature installation of two forwards a heart-shaped condenser microphone, inside front of the reverberation equally surround sound source; inside both sides of T-rack installation and basic slant of in this area 135? the heart-shaped condenser microphone, rear surround sound equally reverberation source. T-Rack using fine wire and through arm lift, if it is choose up a regular stereo source, can befall straightforwardly replaced with standard otherwise generous DECCA tree recording AB, Minute AB, MS, ORTF format, etc..
ATMOS5.1 surround sound microphone pickup logic from Germany's R & D surround sound pre-amplifier, pro the full analog circuit design, can provide all current standard surround sound recording. It uses a fixed "large" type microphone stand, microphone through the cable and at the bottom of pre-amplifiers. The microphone amplifier using the thrilling motor control to advance control of the basic control bulge can befall guaranteed five simultaneous adjustment of the advance of the microphone, microphone amplifier can befall frankly conceded made known inside surround sound microphone advance adjustment, distribution and output bus, audio and record electronic broadening , ultra-low sound indicate and regulation, surround sound and stereo monitor, such equally the conversion and surgical procedure of appropriate
