Hi-Performance 2-channel AD/DA-Converter
Please note that the ADI-1 is discontinued! |
|
|
|
The ADI-1 is a compact, 2-channel analog to digital and digital to analog
converter using half the space of a 19" rack. AD- and DA-circuit can
be used completely independently. The latest 20 bit converters with 128
times oversampling result in more than 100 dB dynamic range. A perfect board
layout makes this value no theoretical maximum but a reality in every ADI-1.
Professional features and optimal sound quality turn the space saving ADI-1
into a flexible and universal all-in-one solution. From 'Phantom of the
Opera' through Radio to the homerecording studio, an application for the
ADI-1 can be found virtually anywhere.
Compare for yourself: The ADI-1 offers maximum
performance for the lowest price!

The clear structured front panel is easy to understand. The level meters
are controlled by the digital audio signal. This results in a hi-precision
LED meter with reliable Over detection. We used the experience in meter technology
from our DAM-1 to give you total accuracy even with this cost effective device.
The AD-converter can use 32, 44,1 or 48 kHz as sample rate, and the DA-converter
accepts every frequency between 20 kHz and 55 kHz at its input. An error
LED shows the status of the currently attached signal. 
One of the main issues in using
an AD-converter with its full dynamic range is the use of the best operating
level. Because of this RME's ADI-1 is fitted with a level switch, maintaining
perfect adaptation to the most used levels -10 dBV and +4 dBu. An additional
super low noise amplifier stage provides 20 dB of adjustable gain using
two hi-precision pots on the front panel.
The servo balanced inputs use Neutrik's well known combi jack (XLR / 1/4"
TRS jack.) The servo balanced outputs are fitted with both XLR and 1/4"
TRS jacks separately (the combi jack is available only as female input jack.)
The digital inputs and outputs are both in SPDIF format and use cinch (RCA)
and optical (TOSLINK) connectors. The digital input is compatible to AES/EBU.
The ADI-1 is not only the ideal
partner for the DIGI96 series digital audio cards, but also an ideal replacement,
supplement or addition for any digital device, from sampler to DAT. The
integrated Dither
On Chip achieves a significantly
improved sound quality compared to usual 16 and 18 bit converters, at full
compatibility to the 16 bit standard.
