Let you become ace understanding and use cinema projector

Most now projector does not contain camera lens translation (LENS SHIFT) function, when choosing hoisting projector accordingly, because notice the camera lens of projector and projector boom center above all whether coincide, if have deviation, so when determining hoisting position, be about to consider deflection is measured. Present most projector designs fixed angle of elevation projectile means, if use hoisting, the height of hoisting also has exquisite, for instance abstruse graph code, 3 water chestnut, when projectile and fixed height and same picture dimension, hoisting height is taller, easy and clingy ceiling, hoisting effect is more good-looking, if say to choose bright base projector is unsuited hoisting, project because of it slant horn is 0 degrees, projector hoisting will be very accordingly low, destroy effect of sitting room environment easily. The hanger of hoisting projector is to use common all-purpose hanger commonly, of white, agile, cabinet, secure easily, but in order to fluctuate adjustable adjustment the position. Also have dynamoelectric hanger, can conceal projector completely inside condole top, of course space of top of this need condole wants a few bigger, suit a layer tall taller sitting room hoisting.

Additionally the power source of projector also is very important, because the picture is bigger, if the picture appears petty ripple, very can easy see, because this suggests to pass a power supply cord to give projector power supply from distribution box directly, in the meantime, need provides control switch, involve projector power supply so with respect to what need not mount climb down every time, what need an attention nevertheless is, the power source of projector cannot be put together with general switch, appear so easily to close the case of power source directly, it is very big to the influence of umbriferous bulb life (general need shuts projector with soft switch first, after waiting for refrigeration again dump) .

What want an attention next is, at the back of projector the choice of video line. Should notice you want the function of implementation finally in wiring, if the function of implementation is different, so capable person of wiring place wiring is different also! For instance: What you choose is now the popular projector that takes digital HDMI interface, so line of HDMI number video wants cloth necessarily, because HDMI can carry digital signal, the picture times line arrives high resolution (720P, 1080P) , promote the definition of umbriferous picture apparently, also can show high-definition signal cause (signal source itself is 720P or 1080P) ; If want to receive TV signal with projector, so most now TV box is interface of electrified head VGA, can make the resolution of the picture achieves 1024 × 768, the result that the TV appearance definition that such coming out and stability want to come out than using video line is good, the laid of VGA line should consider when wiring so; If the function should be received outside implementation game, so off color line (also call heft the line, 3 coaxial lines side by side video line) also be to need of cloth, off color line also can be used see DVD, if have,receive table computer to be able to consider laid DVI or HDMI line, if the projector of your choice has DVI interface, so laid line of a DVI also is advisability lift, because the interface of projector is numerous, so when realizing more function, avoided to make a round trip often insert unplug. Notice even in decorating a process, the HDMI in video line, DVI and VGA had better be the clue that gives in normal factory, and do not go casually the head wears a canal, these connect are the factory solders, if solder by hand,80% meetings affect picture quality, recommend perhaps defeat pipe with thick canal, square chamfer, come to the way that the line sets telescope to go wiring. Above concerns wiring respect, worker master worker can be accomplished. The circular arc that when taking a line, should notice curved horn wants to do as far as possible is a few bigger, lest hurt the screen result to wire. Strong report and weakness endeavor to assure certain distance, prevent magnetism interference.
