There is a problem in the way the unit handles high input signal levels on any source.
When tested with a CD with a sine wave recorded at a level higher than -10dB,the unit
has excessive THD.To get the THD below 1.0%,I must use a test disc recorded at -10dB.
The same high THD problem is also found on the AUX and USB inputs.It is virtually
impossible to measure output with THD lower than 1.0%,regardless of the input level
(50 to 200mV) or volume control setting.There is audible distortion when using the Aux
inputs at any level.
The CD and USB sources will measure acceptable THD levels,but only if the track levels
are at -10dB or lower.See graphs below.
On Sample Two,the distortion in the amplified output increases at lower frequencies.
This can be caused by incorrect capacitor values,or other circuitry problems.See the
Amplified Outputs – THD vs Freq graph below.
To measure the power available below 1.0% THD,I had to use a special 1kHz track
recorded at -10dB.This was the only way to avoid excessive THD.

单元（装置）处理任一来源的高输入信号电平的方式有个问题.
当采用在-10dB以上录制的正弦波测试CD时,单位的总谐波失真过量（过度,过多）.
为使总谐波失真低于1.0%,我必须采用-10dB录制的测试盘.
AUX和USB输入存在相同的高总谐波失真问题.无论输入电平（50至200mV）或音量控制设置如何,几乎不可能采用1.0%以下的总谐波失真测量输出.采用Aux输入,任何电平都会有能够听到的失真.
CD和USB源将测量可以接受的总谐波失真电平,但是只有音轨水平为-10dB或更低时才能做到这一点.见下图.
在样本二上,放大的输出失真在更低频率时增加.
这可能是因为电容值不正确,或者其它电路问题.见下图：放大输出 - 总谐波失真与频率.
为了测量总谐波失真1.0%以下的可用功率,我不得不使用-10dB录制的特殊1kHz音轨.这是避免总谐波失真过量的唯一办法.

There is a problem in the way the unit handles high input signal levels on any source.
这个部件在应对不同来源的“高输入信号”方面有问题。
When tested with a CD with a sine wave recorded at a level higher than -10dB,
the unit has excessive THD.
用CD做高出“-10dB”的正弦波测试时，这个部件超过了“THD”。
To get the THD below 1.0%, I must use a test disc recorded at -10dB.
要让THD低于1.0%，我必须用低于-10dB的值。
The same high THD problem is also found on the AUX and USB inputs. It is virtually。
AUX和USB输入方面也有同样问题，真的。
impossible to measure output with THD lower than 1.0%, regardless of the input level (50 to 200mV) or volume control setting.
在THD低于1.0%情况下，是不可能测出输出值的。不论输入值或容量控制的设定是多少。
There is audible distortion when using the Aux inputs at any level.
用AUX输入时声音失真。
The CD and USB sources will measure acceptable THD levels, but only if the track levels are at -10dB or lower. See graphs below.
CD和USB可以测出可接收的THD水平值，但前提是在track lever低于-10dB。
On Sample Two, the distortion in the amplified output increases at lower frequencies.
关于样品2，在低频时声音失真更严重。
This can be caused by incorrect capacitor values, or other circuitry problems.
不适合的电容器会导致这个结果，或别的线路问题。
See the Amplified Outputs – THD vs Freq graph below.
看下面THD扩音输出VS频率的对比图。
To measure the power available below 1.0% THD, I had to use a special 1kHz track recorded at. This was the only way to avoid excessive THD.
要测出低于1.0%THD的可供电源，只能用特殊的-10dB 的1KHZ的track，这是唯一能避免过度的THD的方法.
