？？？麻烦问下国都前级开1格音量怎么比上1格大很多呢？？？

麻烦问下玩国都的烧友，我收了一套国都前后级（44+606），有几个疑问：

1.前级开1格音量怎么比上1格大很多呢？前级音量即使关到最小都还是有点儿音乐，44前级我接的1.6V这组接606后级，44前级与CD接的AUX这组，应该没有接错吧？

2.前级开机都是亮第一个灯（RADIO)吗？

3.请问44前级的前面板的“TILT”和：“FILTER SLOPE"(滤波器）怎么调？一般调到哪里？







先谢谢坛子里的国都烧友们，我是第一次玩国都，麻烦大家解答一下！！！

QUAD就是如此。夜深人静时用它听音乐很难找到合适的音量。

音量控制唔线性！

它的步进电位器太次了。

还有就是这个顶盖窗里的小片可以调吗？怎么调？麻烦看图，谢了。

44前级接606后级应该选500mV的这组

因为606后级的输入就是500mV

Quad 606 Power Amplifier

The Quad 606 Power Amplifier is another classic amplifier design from Quad utilising their patented current dumping technology. Essentially a current dumping circuit like the Quad 606 Power Amplifier consists of a very high quality low power class A amplifier feeding a high power low quality amplifier which is used when required.
The Quad 606 Power Amplifier was originally launched in 1987 and essentially was a new improved version of Quad's 405 amplifier with extra oomph and a whopping 140 watts per channel into 8 ohms whose sonic improvement compared to original Quad 405-2 was significant.
The Quad 606 Power Amplifier was also very popular with professional audio people as well as audiophiles possibly because of the sheer power of this amplifier coupled with Quad's reputation for producing solid well built amplifiers.
The Quad 606 Power Amplifier was discontinued in 1997 to make way for the Quad 707 power amplifier which was another current dumping design that improved slightly on the Quad 606 and was one of Hi-Fi World's recommended amplifiers at that time.
If any current owners of the Quad 606 Power Amplifier are interested,
Fidele Audio offer an upgrade service which improves the original sound by replacing the class A circuits op amp (Texas Instruments TLC271) with a much a higher quality one - a Burr Brown OPA627AP and upgrading some capacitors with Black Gate (just about the best you can buy - if you can find someone who stocks them). I can certainly vouch for this upgrade as I use a Net Audio modified Quad 405-2 whose upgrade is very similar.

配个66的前级很好调，我现在把66+606放在一边好久了，用300B好听。

谢谢，44前级这个窗口里面没有500MV啊{:soso_e110:}

是这里

我接后级就是接的44前级500MV的1.6V这组接口

masterworks

500MV和1.6V是不同的2组接口啊，最下面一组才是500MV的接口

yyxxqx

就是接下面那个5针的接口，对吗？

往下借就OK了

yyxxqx

下面这个接口还不是5针的{:soso_e127:}，应该是4针的
