英文电子说明书
[1] POWER                   Switches the unit on or off. The unit is ready to operate with the factory
                                 default settings. The subsequent settings remain stored in a Flash EPROM
                                 after switching the unit off (unit contains no battery).
[2] Input dBu FS          Rotary switch for coarse input sensitivity setting in 10 dB steps. OFF position
                                 between microphone and line sensitivity setting ranges.
                           Mic: Range –40...+20 dBu
                           Line: Range +14 dBu, +24 dBu
[3] Fine Gain                Potentiometer for fine input sensitivity setting.
                                    Range of additional gain: 0...+15 dB.
                  Headroom: The input sensitivity setting is calibrated in dBu per full-scale. It represents
                                    the dBu value of an analog input signal which causes a full-scale output of
                                    the A/D converter.
                     Example: A studio works with +4 dBu nominal analog level and uses 12 dB headroom;
                                    the peak level is therefore +16 dBu. The “Input dBu FS” rotary
                                    switch [2] is set to +24 dBu (i.e. gain setting short by 8 dB), and the “Fine
                                    Gain” potentiometer [3] increases the gain by 8 dB.
[4]...[6] Valve Dignifier    Operative only if the function VALVE [8] is active.
[4] Bass Warmth             The sound of low frequencies becomes rounder; bass has more depth; vocals
                                    have more body; percussive instruments are less aggressive.
                                    The group delay behaviour due to AC coupling of the stages is different in
                                    tube amplifiers.
                                    The “Bass Warmth” control allows to select the frequency range
                                    (10...200 Hz) within which the effect is active.
[5] Angel Zoom                Adds transparency and clarity to vocals; emphasizes the solo instruments.
                                    Valve amps have a characteristic response, mid-frequency harmonic content
                                    is emphasized.
[6] Valve Drive Gain/Clip Tight, full sound; the sound will be harder/softer.
                                    The harmonics spectrum of a delicately overloaded valve amplifier is completely
                                    different from an overloaded transistor stage.
                                    The “Gain” control adjusts a gentle overload while the odd-harmonics content
                                    can be adjusted with the “Clip” control.
[7] Line Out                   Output level setting, calibrated in dBu per full scale (dBu FS). Range: 4...24
                                    dBu FS.
[8] VALVE                      Toggle key for inserting the Valve Dignifier stage into the audio path of the
                                    desired channel.
                                    The “VALVE” LED is on when the Valve Dignifier stage is active.
[9] INSERT                      INSERT function.
                                    First key pressure: INSERT POST VALVE, the Insert Send is tapped after
                                    the valve stage (display: “INS”); the Insert Return is directly fed to the Line
                                    and AES/EBU outputs.
                                    Second key pressure: INSERT PRE VALVE, the Insert Send is tapped before
                                    the valve stage (display: “INS” and “PRE”); the Insert Return is fed via
                                    the valve dignifier stage to the Line and AES/EBU outputs.
                                    Third pressure: INSERT OFF, the input signal is fed via the valve dignifier
                                    stage (if active) to the Line and AES/EBU outputs (also the Insert Send output
                                    receives this signal; display: none).
                                    Insert Send and Insert Return are electronically balanced and equipped with
                                    XLR connectors.
[10] ROUTING                Selector for the channel routing when using one of the (optional) TDIF or
                                    ADAT digital interfaces. Each input channel can be switched to one of the
                                    channels 1...8 of the multichannel interface. If desired, also a mono mix is
                                    possible by selecting the same output channel for both input channels.
[11] 48 V                      Toggle key to activate the 48 V phantom power supply for the desired microphone
                                    channel.
                                    Can be operated only if the input gain selector is in Mic position. The
                                    setting remains stored when switching over to a line gain setting.
[12]                               Activates the high pass filter on the microphone inputs of the desired channel.
                                    Cut-off frequency (–3 dB point) 75 Hz, slope 12 dB/octave.
                                    Can be operated only if the input gain selector is in Mic position. The
                                    setting remains stored when switching over to a line gain setting.
[13] Ø                Toggle key to activate the phase reverse switch of the desired channel.
[14] MODE                      Toggle key to select the word length of the DIGITAL OUTput. 20 bit (display:
                                    “20BIT”), 16 bit with dithering (display: “16DI”), or 16 bit with
                                    Noise Shaping (display: “16NS”) can be selected.
[15] SYNC                      Selects the synchronization source for the unit. Possible selections are:
                                    INT 48 Internal quartz reference, 48 kHz
                                    INT 44 Internal quartz reference, 44.1 kHz
                                    WCLK Selects external Word Clock Sync (flashes if no valid input signal is recognized)
                                    AES Selects external AES/EBU Sync (flashes if no valid input signal is recognized)
                                    AUTO Selects sources automatically in the sequence AES-WCLK-INT
                                    VAR Indication only, active if the external source frequency deviates from 48 or
                                    44.1 kHz for more than approx. ±3 %.
[16] PEAK HOLD             Toggle key to select the PEAK HOLD function for the PPM level meters –
                                    either permanently (display: “HOLD”), or with automatic reset after approx.  2 s.
[17] SOFT CLIP             Toggle key to activate the SOFT CLIP function in the analog paths to reduce
                                    the danger of overloading the A/D converter with short signal peaks (if
                                    active, the display indicates “SOFT”). Threshold at 3 dB below full-scale,
                                    allowing for approx. 6 dB reserve before hard clipping occurs

已开声，对比STUDER A779调音台，声音更宽松、清晰度更好。按MODE键分别点亮16ＤＩ、16ＮＳ、20ＢＩＴ这几个灯，都有声音出来。
卢老师方便时帮我大概翻译一下上面的英文说明书，谢谢{:4_226:}

[16] PEAK HOLD    拨动键选择PPM米的峰值保持功能 - 无论是永久（显示：“HOLD”字样），或约后自动复位。 2秒。
[17]soft clip             软夹切换键激活软CLIP功能，在模拟路径，以减少（如果超载短信号峰A / D转换的危险活跃，显示屏显示 “软”）。阈值低于满刻度的3分贝，允许约。 6分贝储备硬剪裁发生前
请教：按上面16、17这两个键显示屏分别会显示：“HOLD” “soft”字样,是否表示点亮这两指示灯就会保持信号不会过载。

[13]&    切换键激活所需通道的相位反转开关这是按键什么意思？

fine gain 、 valve drive gain这两个旋钮大概是增益电位器的意思？

[8]VALVE    阀切换键插入的音频路径阀门Dignifier阶段所需的通道。 “阀门”LED是当阀门Dignifier阶段是积极的。这个按键点亮后马上感觉声音活生感好了，是否这时的信号经过电子管电路？

[4]Bass Warmth 、[5]Angel Zoom  、[6]Valve Drive Clip  这3个旋钮转动时感觉声音变化不大，是麦克风用的？

功能已基本明了个大概了，谢谢卢老师和上面的兄弟{:4_226:}

这东东的声音和STUDER A779调音台比较，主要在声音的细节、透明度、乐感方面有改善，
但用它，前级或后级必须要有音量调整。

4支电子管有两支估计老化了，灯丝不是很亮，和另两个比，管帽顶发黑，另两支是不同牌子的，不知道对音质影响有几大？
