Public known the A725 stub B225 differences, mainly in 塊 balance on circuit board. Both ten years future this 塊 Board has been brought with a kind of God secret of color, 傳 said is for because this 塊 balance die team let A725 of Sheng sound than up B225 high Shang ten both coating/f, most non-balance type of players also are choose liquid put A725 of balance input out threes, into veneered end input out, and deny 棄 A725 itself of veneered end input out, this 塊 balance board what has what so secret? It was curious.
Promote original facility TV road Seattle miles, can clear see this 塊 die team is received in D/A threes, views 後 by half 顆 NE5532 team into of OPAMP unity gain buffer input out, this 顆 OPAMP except through over 100uF of TV capacity 負 Ze push begins to veneered end input out, still 負 Ze put input out 訊 Hao sent to volume can change zoom TV road and balance input out die team. 順 談 A725 to change volume on, for Prada to the digital volume control, A725 is his XI 訊 Hao quality, Hao to the digital 訊 顆 Analog Device AD7528 Tri-Vocal tract 8bits digital Analogy for ETA conversion, this 顆 D/A can be controlled over the CPU on the volume. Web road was said this team input out Sheng sound is good, also was said with this team input out future Zambia whole volume, than through over Qian class volume control Sheng sound still better and so, only said the method into the eye has, I real people is said what so are not Club Med with this team 8bits input out of, to 後 I still wants to put this team D/A FA has, so as not to shadow 響 TV source.
Due to the Vocal tract is completely around Symmetry, this analysis only the left Vocal tract. Balancing on a circuit board, 訊 Hao is the first class of over 顆 22uF Capacitance electronic solutions entered IC11,IC11 NE5534 veneered OPAMP, make a class unity gain buffer amplifer, NE5532 suriel is two 顆 NE5534 integral. IC11 on over 顆 2.2k of electric resistance of stub 顆 100uF Capacitance electronic solutions, entered IC12 positive input of OPAMP foot IC12 on termination of the two I'm SOT: small outline transistor Q101 stub Q102, this set of two crystal Stadium base 極 顆 stub 極 short-circuit, so JI 極-launched orbiting 極 導 pass, Two-side pressure drop 0.3V, strung up Q103 stub Q104 which I'm SOT: small outline transistor base 極 partial pressure, Q103 stub Q104 posted by common-emitter 極 push-pull on, just like the AB class amplifier model courses, push begins 負 download (anform). This stadium does not provide any gains four 顆 ceramic, pure vegetable essence is lower the OPAMP voltage output only, on directly back to the OPAMP in 負 ends input, if one circuit as a whole 顆 OPAMP, basic non-inverting this is unity gain buffer.
Addition half 顆 NE5532 and Q105~Q108 team into of TV road than 較 interesting, OPAMP of are end input into directly grounding, and 負 end input into entering into is received in two 顆 1.5kOhms points pressure TV resistance of in the between, by in this two 顆 TV resistance is across received in input out change pressure device early class 繞 resistance two end, so if TV road is full balance of said this real place Ying this having when keep in 0 TV bit. Fake design put this whole team TV road including four 顆 TV Crystal Stadium also like above a model courses as a real big OPAMP, this 顆 OPAMP having when put change pressure device in the little TV bit Club Med and to TV bit than 較, if has any poor replacement, on Club Med through over input out end 驅 begins to input out change pressure device of early class 繞 resistance future design method put input out in the little pulled back zero TV bit, using this real principle, this real TV road not only complexity manufacture has Shang half Department TV road of waveform (phase 180 degrees), also prevent DC flow over input out change device early class.
A725 are studied all of the circuit for some Userboxes/Time, istm it seems to me Studer good Club Med Sheng does not have any secret, that is, step by step, without stealing workers reduce the materials. He we of design total also no has what so release 燒 sound 響 of concept, a heap TV solutions TV capacity in 訊 Hao road 徑 Shang, large using CIS row plug for 訊 Hao links received, yes Studer of engineering Normal University future said, TV road 穩 set durable stub easy in Tel Aviv repair is 優 first test 慮, after all had this some equipment is 專 operating DVD sound room stub TV Taiwan using.
With veneered end input out than 較, except input out change pressure device yiwai, balance input out TV road of letter Hao road 徑 Shang more has two 顆 TV solutions TV capacity and a heap TV Crystal Stadium, supposed said more support incense 爐 more support ghost, Sheng sound not Ying this than veneered end input out good is, not over right international Shang Ting up future balance input out of true than veneered end praised. I guess there are two reasons, first is to balance on the true gain much higher, the second is to balance on low on impedance comparison. If you can remove the balancing electronic 訊 徑 Hao road two 顆 Capacitance electronic solutions, Ying this'll praise it, do you? Next article'll answer.
