既然说A1了，，继续说一个KX驱动的问题

A1，，和ZS还有用后置声道的必要吗？

说实在我实在看不出ZS用后置声道的理由，，，
继续请高人指点

上了KX驱动用后置输出，，那只是局限于LIVE！~

A的后置声道跟前声道都是同一解码出来的声音，还有不一样吗？:lol:

A2zs后置声道不是说是Codec＋运放出来的，效果要好些么？

我想知道是谁说的，，
原理是什么

Live4620 就后置的DAC比较强
Audigy，，好像后置都一样的，，
起码我见过的ZS，，是一样的

就运放有区别

后置明显比前置的声音来的好。好像是说在某种程度上可以绕过SRC。

都是经过EMU10K2的，，
有什么确切的证据，，说明EMU10K2的后置声道和前置的输出不一样？？

Timme · 发表于 2006-9-5 00:48

Kx说，前置是Codec+DAC输出，其他是纯DAC输出，所以后置之类要好

amd_alex · 发表于 2006-9-5 08:11

呵呵,没有证据,但前置和后置明显声音会不同,后置的更加通透的感觉!!我想这也是为什么KX是默认后置的原因吧!!1

这个说法适用于所有多声道的CODEC？？

Front and Rear issues

These issues pertain to all Creative cards, but not to the E-mu APS and some Audigy2 Platinum Ex cards. Creative audio cards based on the EMU10kX audio DSP require a DAC (Digital to Analog Converter) in order to produce analog output. In general, this task is typically performed by either AC97 Codecs or I2S Codecs.

The AC97 Codecs used in SBLive! cards are rather noisy devices (when compared to I2S Codecs), and this leads to some quality problems. As a rule, SBLive Rear outputs have much better Signal To Noise Ratio (SNR), Total Harmonic Distortion (THD) and Channel Separation (acs) since they use the I2S Codec. So, if you want to get better sound quality for music playback it is recommended that you plug your speakers into the 'Rear Out' and enable the 'Swap Front and Rear' kX Mixer option (the swap is enabled by default).

The Audigy and Audigy2 cards use both AC97 and I2S Codecs for Front output and this theoretically gives you rather good Front quality. But nevertheless, the AC97 Codec causes some distortion and thus the same procedure is recommended for use with Audigy / Audigy2 cards as well.

E文，，要慢慢看了

按照KX的说法

其他AC97声卡都应该试用，，

而类似于6Fire LT的就不适用，，
邮独立ADC的，，就不用说了

是这样吧

sd-iori · 发表于 2006-9-5 13:09

不过，，Audigy系列声卡的Codec怎么能算AC97呢？？
