所有MEDEA都能升级MEDEA+ ！！！
MEDEA+此次为全新设计，理应取个全新的名字以示区别，但是Dianel weiss是一位非常有
责任心的老先生。他在设计MEDEA+时就下决心一定要能使最早的MEDEA用户都能升级，所
以
我们能为所有MEDEA用户提供更换全新电路板升级至MEDEA+的服务。（寄回瑞士）
MEDEA+ 此次为惊人的全新设计，是28万美金定制DA/AD WEISS MAYA的精华浓缩，使用了
参
考级的32/192芯片，并配上了8片纯甲分立放大模块，音质提升之大，可谓惊人天人！
具体参数如下：A NEW I/V CONVERSION AND OUTPUT STAGE FOR WEISS FLAGSHIP MEDEA+
DIGITAL TO ANALOGUE CONVERTER
Superb noise performance:
1nV/√Hz voltage noise density (1kHz)
30nVpp voltage noise (0.1-10Hz)
0.7pA/√Hz current noise density (1kHz)
80pApp current noise (0.1-10Hz)
no common-mode current noise from bias cancellation
Outstanding distortion specifications:
THD+N -152dB (+20dBu, 1kHz, 22kHz BW, 600Ω)
THD+N -148dB (+20dBu, 10kHz, 80kHz BW, 600Ω)
distortion spectrum consists almost entirely of 2nd and 3rd harmonic
no significant crossover distortion, even with 200Ω load
no significant common mode distortion, even with very high source impedances
Impressive AC performance:
50V/µs slew rte, highly symmetrical
95MHz gain bandwidth product
700kHz power bandwidth (20Vpp into 600Ω)
300kHz power bandwidth (20Vpp into 200Ω)
Superior DC precision:
offset 10µV
input bias current +-60nA
input offset current +-10nA
Excellent load driving capability:
27Vpp(+21.8dBu) in 200Ω (+-15V supply)
20Vpp(+19.2dBu) in 100Ω (+-15V supply)
10Vpp(+13.2dBu) in 50Ω (+-15V supply)
adjustable class A output current, factory trimmed to 30mA
very low output impedance
extensive short-circuit protection
Salient insensitivity to power supply deficiencies:
very high PSRR with little degradtion towards high frequencies
individual RC decoupling of amplifier sub-circuits eliminates the interaction
of the various amplifier stages and makes the amplifier insensitive to power
supply inductance
high performance on-board decoupling capacitors, 2.4µF total
no need for additional external decoupling capacitors
recommended power supply range from +-5V to +-18V
Carefully thermal design:
excellent stability of any bias condition
full thermal isolation of the sensitive input stage from the power output
stage
fast settling of bias conditions after start up
Dimensions:
42 x 28 x 17mm (1.65 x 1.1 x 0.67 inches)
API2520 standard pinout
