L
ike its predecessor the ADA-8, the
PrismSound Dream ADA-8XR is a
modular A/D-D/A converter and
processor that can be configured for
eight channels of simultaneous A/D and
D/A conversion or for 16 channels in either
direction. It supports 24-bit/192 kHz opera-
tion and it can also serve as a D/D format
converter. The box is perfectly suited for
studio and location recording, stereo and
surround mixing and mastering.
FEATURES
The 2RU ADA-8XR can be adapted to
virtually any situation. Each of the ADA-
8XR’s paths of eight channels is indepen-
dently configurable and if desired, can have
independent clock references and different
sample rates. And each path can drive ana-
log and digital outputs simultaneously if
desired
The unit features a host of digital inter-
facing options that include: AES3-S/PDIF
(up to 192 kHz); handles and converts two-
wire formats for 96 kHz and 192 kHz;
FireWire (which provides direct connection
to DAW software on PC or Mac); DSD (for
SACD production, with SDIF2/3 and
optional MAC-DSD); also allows sample
rate conversion between any PCM rates, Pro
Tools 24/Mix (direct connection in place of
888 IO), and Pro Tools/HD (192IO/96IOs;
up to 32 channels in and out per Digi
Core/Process card).
The ADA-8XR can act as a high resolu-
tion Pro Tools interface for recording or post
production or, by using the FireWire card, it
can work with a wide range of other popular
digital audio workstations including Digital
Performer, Logic, Cubase, Nuendo, etc.
The DSD I/O module is equipped with
SDIF-2, SDIF-3 and MAC-DSD interfaces.
DSP features include eight-channel PCM-
to-DSD and DSD-to-PCM conversion (any
PCM sample rate), plus eight-channel PCM
sample rate conversion. By fitting the Pro
Tools/HD and the DSD modules, Pro Tools
can record and replay DSD audio, allowing
SACD master recordings to be produced
within Pro Tools.
The ADA-8XR’s analog XLR inputs and
outputs are electronically balanced, trans-
formerless and galvanically isolated to pre-
vent unwanted noise. The analog input and
output sensitivity (and interchannel balance)
are software-adjustable over the entire range
with 0.05 dB resolution. The analog inputs
have a dynamic range of 112 dB (rms
unweighted, measured at –60 dB FS). The
THD+N is –105 dB (0.0004%) typical, rms
unweighted at -1.0 dB FS. The analog out-
puts have a dynamic range of 110 dB (rms
unweighted, measured at –60 dB FS). The
THD+N is –104 dB (0.0004%) typical, rms
unweighted at -1.0 dB FS. Additionally,
there is a TASCAM DA-88/iZ RADAR
compatible DB25 connector option avail-
able for the analog inputs and outputs.
The ADA-8XR’s Ultimate PrismSound
clock-stability and jitter-rejection provide
crystal clear imaging, with independent
multiple PLLs for A/D and D/A paths. The
Over-killer setting provides gentle limiting
for analog inputs and assures no overs. It
can be independently turned on and off on
each channel.
The user interface provides fast access to
all I/O and processing functions while
