Manley DIGITAL TO ANALOGUE CONVERTER DAC 1994 - 1995 - Manual (Page 3)

THANK YOU!...
for choosing the Manley Laboratories REFERENCE 20 BIT DIGITAL TO ANALOGUE
CONVERTER. Please read over this manual carefully as it contains information essential to
proper operation of this unit.
The MANLEY DIGITAL TO ANALOGUE CONVERTER features completely dual-mono
analogue sections and power supplies, the heart of which is the only TRUE 20-BIT, 128x
oversampling converter unit available today, custom made for us by ULTRAANALOG. By
"TRUE 20-BIT" we mean that full 20 bit perfomance IS actually achieved from years of
exhaustive research and engineering on the converter chip itself. While some converters claim
to be 20 bit, or 18 bit, or 16 bit, seldomly is the 18th, 16th, or 14th bit performance ever
reached. The 8x oversamplig rate at which the ULTRAANALOG operates eliminates the need
for steep anti-alias filters, and eliminates differential non-linearity and harmonic distortion for
low amplitude signals. The AES-21 chip effectively removes incoming jitter from the digital
inputs. For maximum fidelity and musical involvement the line amplifier is a low impedance all
vacuum tube design.
GENERAL NOTES
LOCATION & VENTILATION
The MANLEY DIGITAL TO ANALOGUE CONVERTER must be installed in a stable
location with ample ventilation. It is recommended, if this unit is rack mounted, that you allow
enough clearance on the top and bottom of the preamp such that a constant flow of air can flow
through the ventilation slots.
