Circuit Feature
(1)Able to be applied to CD/DVD and black Lacquer disk phonograph( RIAA ).
(2)Amplifier provided with output of high/low two electric levels,namely ( 0.7V / 0.2V ),
so that it is applicable to pure post-stage amplifier and integrated amplifier.
(3)Black lacquer pickup amplifier adopts negative-negative feedback typed
equalization circuit, in conformity to RIAA characters with good acoustic quality.
(4)The preceding stage amplifier takes a negative pole output circuit, featuring an
advantage of transmission with loa impedance.
回路の特徴
(1) CD/DVDに適用可能で黒ラッカーのディスクフォノグラフ（RIAA）
(2) ハイ／ローの2つのエレクトリックレベル出力付きアンプ（0.7V/0.2V）で、ピュアなポストステージアンプと統合型アンプに適用可能。
(3) 黒のラッカーのピックアップアンプはネガティブ－ネガティブフィードバックタイプのイコライゼーション回路を採用しており、良好なアコースティック品質でRIAAキャラクターに適合。
(4) 先行ステージアンプはネガティブポール出力回路を採用しており、loaインピーダンスのトランスミッションが優れているのが特徴。
(5)Touch typed relay transformation is adopted for signal transformation.
The filament of electron tube refers to DC power supply, so that noise with this
amplifier is minimized.
(6)This amplifier is manufactured by using linked capacitance special for import
audio frequency ( MKP ) as well as filtration electrolyse and quality metal
resistance special for import acoustics.
(7)The power supply transformer is made of oxugen-free enameled copper wire and
silicon steel plate special for import acoustics.
(8)12AX7 Tube and Screening Aliminum Shell
Attention: Screening Aluminum Shell plays the function for shielding tube, and
please remove it during use.
(9)Power Input Receptacle and Protector Tube
The input voltage of this receptacle is AC110V +/-10% ( 50Hz/60Hz ) and that for
protector tube is F1AL250V.
(10)Power Input Socket ( OUTPUT 0.25V )
This signal output socket can be connected in the place of sound source
input ( INPUT ) for integrated amplifier.
(11)Signal Output Socket ( OUTPUT 0.7V )
This signal output socket can be connected in the place of input socket for
preceding stage of pure post-stage amplfire
(12)Power connected and indicator light not on
If power supply plug is well inserted, if power is available with socket, if protector is
disconected, and if power switch key is pushed or not.
(13)Mute entirely
If input signal function switch is correctly selected, if rear plate conection is correct,
if signal plug is reliably connected, and if the power supply for signal source is
turned on or not.
(14)Right main sound box silent
If line for sound box is disconnected, or in short circuit, if signal plug is correctly
connected, or if signal line is in short circuit or open circuit, or not.
(15)Wrong sound image positions
If " + , - " of sound box and " + , - " of PA are inversely connected, if sound box is
wrongly placed, or if piracy audio-visual product is being played, or not.
(16)AC sound or any other sound
If input signal wire or plug is improperly contacted, if non-shielding or
poor-screening signal wire is used, if welding machine, power geberator,
or engine are working and interfering nearby, if noise exists with program source
itself, or tube and tube holder are loosened or in bad contact or not ( can pull our
the tube, clean the pins, and then insert it into the holder again ).
