标题: ASR basis exclusive唱放求科普
E文不行，搞不懂ASR basis exclusive唱放主机和电源上各个led的含义，那位老大懂的请不吝指教，谢谢！

表示各個部門還有電，跟維修師傅有關係，跟用戶沒關係！

不是很明白你的意思。如有英文的文献的话，我可帮你看看。

谢谢rock！！
关键是如何设置，还有各个led的含义。

4.2    Monitor Leds
The operation mode is monitored in the Main unit by some leds around the switch ON knob:
Line Operation with a yellow led,in Batt operation an additionally blue Led comes ON,
Input A is shown with a green led,input B is shown with a red led.

In the battery power supply unit during “Batt” operation a blue led Bar is showing “Batt ON”.
In all other positions the display is showing a yellow bar with “Charge”.

Additionally the operation voltage is shown with 4 yellow and 4 blue Leds in front of the main unit:
The 4 yellow led for are shining in,, Line”mode,the blue ones light up additionally in,, Batt” mode.

There is 1 led for the positive and i led for the negative voltage of the both colours at each channel.

LED是发光二极管。机器打开的话,Line的LED发黄光。电池工作的话,BATT的篮LED亮。输入A的话,LED为绿色,输入B的话,其LED是红色。

电源部分的LED是篮的话,说明电池充足可以工作,黄色的话表明在充电。

在面板还有四个黄色的LED和四个蓝色的LED来表明工作时的电压。4个黄的LED亮表明在工作,四个蓝色的LED同时也亮的话,这表明是电池也在工作。(这段英语很烂)

机里?有一LED代表正极,另一个代表负极。

下面这些有关在电源板上LED作用对你是没有用的。
Function explanation and description of the control Leds
       turned Off (Off-mode):the batteries are charged with 20Volt.The yellow“    ”Led
is shining.When full(19,5Volt)the green Leds“Batt+Full”and“Batt-Full”are shining.

       Turned On(Line-mode):the batteries are charged with 20V.The main unit is supplied
With+/-12 Volts out of the charging circuit to preheat the built in circuits.
The red“Standby”and“10V”Leds are shining.

       turned on (Batt-mode):The yellow led“ ”and the blue Led“Line Off”are shining
then the batteries are switched to the buffering capacitors with 2 Power Mos-Fets.

       Then the charging transformer is separated via relay in both phases from the AC power line.
The green Led“Batt On”and two blue Leds“Batt+ON”and“Bat-ON”are shining.

       during,,Batt“-mode the voltage at the batteries is constantly monitored.When the voltage is
Lower than 17 Volts the batteries are empty,and the Batt Full Leds will go out.The Battery PSU
Switches into the charging mode and the main unit is supplied oout of the charging circuitry.
       Also during charging the main unit is working and you can still listen to music.
       When the batteries are fully charged the voltage reaches 19,5 Volts and the green Leds
“Batt+Full”and “Batt-Full”are shining.Then the charging transformer is disconnected,
and the ASR Basis Exclusive is supplied again out of the batteries.

       fully charged,the batteries can supply the ASR basis Exclusive for approximately 60 hours.
To lengthen the lifetime of the batteries please turn the main unit to the,, Line“position after
Approximately 24 hours of playing in “Batt”position,or just over night.In this case the batteries
Are not much discharged.Lower quantity of discharging is good for the battery life expectancy.
One hour of charging is equivalent to about three hours of playing music.

JWAang版，辛苦了。

我就是不知道每次要充多久电池才满，我试过连续充两天充电指示灯还亮着。

还想劳烦J版帮看看，平衡与单端输入的调整、设定。拜托

Definition of a balanced connection:

A balanced tone arm cable must have two conductors and a separate shielding.
This shielding has to connected separately to ground and should never be connected to the plus or
Minus wires- otherwise you will get heavydistortions, cause the shield will work as antenna!
Balanced cables can be connected at both the RCA or the XLR plug.Both inputs sockets are
Internally connected. The RCA inner pin is connected to Plus, the outer ring to Minus.
The pins on the XLR sockets are international standard: 1 =Ground, 2 =Plus 3 =Minus.
The only advantage of using XLR is that the third pin 1 can be used for ground connection of the
Shield. At RCA the shield must be connected separately to the big ground pole plug connector.
A tone arm cable that has already two wires and be converted simply by connecting the shield to
Ground( the black pole plug at the Basis) instead of to the outer ring at RCA what is minus.

厂家强力推荐用平衡的。这机的平衡是1地2正3负。机内的RCA和平衡插座都是联在一起的。也就是说,只要是接地的是单独的,不管RCA的接头还是平衡的接头。这就是厂家定义的平衡线。

At balanced connections the adjustments have to be made at both 12 Pin Dip switches left
And right. The switch Dip No.12 has to be OFF.

要用平衡的话,机里的DIP双列开关上的12必须放在关闭上。

Unbalanced connection:
An unbalanced tone arm cable is normally coaxial with one conductor and a shielding.
Cables with two inner wires can be converted simply by separating the shield from minus.
Unbalanced cables should be connected to the RCA plug. The RCA inner pin is connected to inner
wire, the outer ring to the shielding.
MM cartridges must be connected in the unbalanced mode.
At unbalanced connections the adjustments has to be made at the left 12 pole Dip switch.
The right Dip switch No.12 has to be ON to connect the minus input to ground.

单端接法必须用RCA线。MM的唱头必须用单端的接法。这样,DIP上12必须打开。

In balanced mode both the Dip switches marked with “Unbalanced”and “Balanced”
No. 1 to 9 per input channel must be adjusted in the same way to get the same load resistance for
Both the positive and ngeative input!

在平衡输入时,两个DIP(单端和手衡)上1至9都必须调在同一位置。见下图和表。

[attach]68531[/attach]

[attach]68532[/attach]

MC的唱头推荐的输入阻抗为20到250欧。

We don’t recommend higher values than 9,4 k Ohms in balanced mode, cause
This may cause higher noise and maybe unstable operation of the input stage.

厂家不推荐在平衡输入下输入阻抗为9。4K及以高于9.4K。

In unbalanced mode only the left Dip switches No 1 to 10 per input channel must be adjusted.
At the right Dip switch only the switch No. 12 has to be switched ON.
That shortens the negative input to ground.

单端输入下,只有左边的DIP中的1至10要用。(图中红色的)。右边的DIP(黑色的)中的12要打开。

[attach]68533[/attach]

[attach]68534[/attach]

MM Cartridges can only be used in unbalanced mode!
For MM cartridges we recommend values of 47 k, what means all Dip switches left to OFF.

厂家推荐MM唱头用47k,这样意味着所有开关都在关的位置上。

The input capacity in unbalanced mode can be adjusted on the left DIP switch No. 12:
Position,, Off“=100pF, ,,On“=320pF, Number 11 at theleft dip switches to 570 pF.
[attach]68535[/attach]

首先,你得用唱头厂家推荐的输入容量减去你唱臂线的电容,然后得出你要调节的电容量。在单端输入时,左边的DIP中12在关时,输入容量为100pF,在开时为320pF,11打开为570pF。

For balancedmode you can use the Dip switches Number 11 left

And rightto in increase the input capacity from 100 to 570 pF.

在平衡输入时,同时打开左和右边的DIP中的11为570pF。

调增益,见下图。

低频过滤开关。打开,2Hz以下给滤掉。关上,20Hz以下给滤掉。

[attach]68537[/attach]

厂家推荐的些常用的设定。

[attach]68538[/attach]

MC，低输出,平衡,94欧,+18dB

MC，中等输出,平衡,950欧,+12dB

MC，中等输出,单端,1K,+12dB

MM，高输出,单端,47k,320pF,+4dB

我想知道增益选择是否可以用组合式。还是必须只能单选。谢谢！

作者: 阿七 时间: 2013-4-19 16:07
感谢J版！

已经打印出来，待晚上细细研究一番

作者: Jwang 时间: 2013-4-20 23:01
如把增益的开关全打开可达最大,70dB(32+38)。此机最小的增益是32dB,也就是说,所有的开关都关掉,其增益为32dB。在开关上,每个开关上的增益都要加上32dB。如果两个开关同时打关,比如说3和4,你得到的是22dB,不是30dB。(这里的计算是如何得出的,说明书中没说明)。
