最近想买red 7,请问问你买可以么？
抱歉，我不负责销售的。但是可以帮你提些建议：
RED7网上报价是$2,199.97 ,
而VoiceMaster Pro, 它与BlueBird的话筒捆机销售才$1,299.97, 并可选配24 bit, 96 kHz 数字输出接口。
....
与原VoiceMaster相比VoiceMaster Pro has...(功能十分强大，在声音处理上能想到的它都有）
Latency-free monitoring section - a separate stereo monitoring circuit that allows the user to monitor vocal + FX loop (e.g. to add reverb) + mix played back from e.g. DAW and control levels of these three sources, removing latency. (VoiceMaster has no monitoring section.)
24/96 digital output option, using the same A/D card as Penta and Trak Master. (VoiceMaster has no digital connectivity.)
Backlit VU output meter (VoiceMaster has no VU meter)
Instrument input in addition to line and mic inputs.
Insert send and return, between mic pre and expander. (VoiceMaster has no insert.)
Vintage Harmonics section. (VoiceMaster has only tape saturation simulator.)
Routing flexibility (Vintage Harmonics and Compressor order can be reversed, and compressor and EQ order can also be reversed, hence 4 combinations of these 3 sections possible. (VoiceMaster has fixed processing block order.)
2U chassis. (VoiceMaster is 1U.)
6-LED input meter. (VoiceMaster has only single LED.)
6-LED expander meter. (VoiceMaster has only 4-LED meter.)
New lower noise opto compressor.
New lower noise opto expander.
New Tube Sound section. (VoiceMaster has none.) VoiceMaster Pro circuit also includes new tone control feature and sexy, 3-colour large LED.
More flexible EQ - now has frequency shift for HF (10k or 14k) and depth of notch filter ("absence") can now be varied. (VoiceMaster has no HF shift and fixed depth of notch.)
New de-esser- now features the ISA 430 de-esser - includes the 'listen' function, so that the sidechain of the de-esser can be isolated, making setting up the frequency to de-ess very easy.
6-LED De-esser meter. (VoiceMaster has only single LED.)
L+R Monitor inputs and outputs. (VoiceMaster has none.)
FX mono send and stereo return. (VoiveMaster has none.)
