供应销售edwards audio全线产品! 立体声话筒放大器!
the edwards audio research le-10 stereo preamp brings your
studio the warmth of vacuum tubes with a frequency response that
goes beyond the spectrum of digital audio.
edwards audio consulted the rca tube manual, the bible of tube
technology, when developing the le-10. they found they needed about
280v dc to ensure the tubes worked under optimal conditions. to
make this happen, they designed their own power supply with this
heightened voltage allowance. many of today's preamps use only a
fraction of this voltage.
the le-10 uses high components such as neutrik or
amphenol xlrs, jensen transformers, hand selected tubes, quiet
potentiometers by bournes, quiet film type resistors, high
capacitors and well designed printed circuit boards.
specifications:
•frequency response: 20hz - 20,000 hz ( -.8db at 20 hz / -1.75 db
at 20,000 hz)
•total harmonic distortion (thd): .05% (ref. 1k tone at 0 vu)
•microphone input impedance: 250 ohm balanced
•xlrgain - high / low: 64 db / 58 db (ref. 0 vu - 1k tone 1.2v
output)
•signal to noise ratio: -80 db (ref. 0 vu - 1k tone 1.2v
output)
•phantom power: 48v dc switchable
•bass cut: 6db per octave (-6db at 50 hz)
•output impedance: 600 ohm balanced xlr
•headroom: +21 db above 0 db level
•driving impedance = 150 ohm into input / 100k ohm load at the
output
