Audient sets the price/performance standard for multichannel preamps.
Amongst audio professionals
Audient equipment is renowned for its ability to provide high performance transparent sound and intelligent ergonomic design
in a cost-effective package. The ASP008 is a compact 1U rack mount unit featuring eight ultra-high-quality mic preamplifiers
developed from the outstanding mic pre design used in the acclaimed ASP8024 recording console. (The ASP8024 rivals the sound
of many "A" room consoles at a fraction of the cost.) If you're looking to add eight great preamps to your studio or portable
rig for a remarkably reasonable price we recommend a close look at the ASP008-ADAT with Audient's ADAT digital option card
pre-installed. The ADAT lightpipe interface makes it the perfect companion for Pro Tools LE MOTU and other systems with ADAT
lightpipe inputs.
Audient ASP008 8 Channel Variable Input Impedance Mic Preamp First Take:
- 8
channels of ultra-high-quality preamps
- ADAT digital interface
- Transparent audio with variable impedance
for tone shaping
- Electronically balanced XLR I/O and two instrument DIs
Ultra-high-quality preamps
The design uses an 8 transistor discrete Class A front end with extended bandwidth and a noise floor close to the theoretical
Johnson limit. (Johnson noise is random white noise generated by thermal agitation of electrons and is the limiting minimum
noise any circuit can attain at a given temperature.) Carefully chosen close tolerance components are used to achieve high
Common Mode Rejection at all gain settings (eliminates unwanted RF and electromagnet field-generated noise allowing long cable
runs) and distortion is minimized to less than 0.001% at 20dB gain and +10dBu output. This outstanding technical performance
delivers a mic amp with incredible transparency and detail without coloration or other unwanted artifacts.
ADAT
digital output
The ADAT digital interface card provides ADAT digital outputs at either 44.1 or 48kHz sample
rates (selectable on the front panel) for all 8 channels on a single lightpipe output connector. The outputs can be set to
16- 20- or 24- bit depth using the front panel controls. A BNC along with an INT/EXT function select switch is also provided
on the digital output card. With the switch released the ASP008 will run off its internal clock generator. Depressing the
switch allows a master word clock to be connected via the BNC connector enabling the ASP008 converters to be sync'd to an
external source. The front-panel-mounted Lock LED will illuminate when the unit is locked.
Transparent audio
with variable impedance
Audient's design philosophy as far as sound quality is concerned is to make the
most transparent sounding preamps possible. According to founder and designer Dave Dearden colored preamps tend to become
one-trick-ponies since that color may not be appropriate for every recording application. However with transparent preamps
you have the option of adding color later on. To achieve this the ASP008's preamps boast an ultra-wide frequency response
of -0.3dB @10Hz to -3dB @300kHz at unity gain and a Total Harmonic Distortion rating of better than 0.007% at 1kHz any gain
setting. If you know your specs you know that this is pretty incredible especially when you realize that you only find specs
such as this on single-channel preamps costing twice as much as the Audient 8-channel ASP008. Each microphone amp on the ASP008
also features switchable input impedance which allows you to explore subtle variations in microphone character and achieve
the best performance for your mics.
Electronically balanced XLR I/O
The ASP008 has been
designed and developed to provide highly robust system integration interfaces allowing worry-free system hook-up under the
most demanding situations. Inputs and outputs are implemented using advanced electronically balanced topologies and are fitted
with extensive RFI rejection networks. Additionally Channels 1 and 2 have front panel mounted unbalanced high impedance jack
inputs to allow instruments to be directly connected to the ASP008. Electronically balanced microphone inputs are provided
on 3pin XLR female connectors with Pin 2 Hot and Pin 3 Cold. Pin 1 is permanently connected to the ASP008 chassis and thereby
to the safety earth. Line level inputs and outputs are provided on 25 pin D Sub female type connectors with 4-40 screw thread
jack posts. Wiring is in accordance with the TASCAMTM DA88 convention.
All channels feature 'soft start' 48V phantom
power switchable input impedance 25-250Hz hi-pass filter line input selection and phase reverse. Channels 1 and 2 also feature
a -20dB attenuator and a high-impedance Instrument/DI input on a front panel mounted jack. LEDs provide indication of signal
present and overload.
Who is Audient and what makes them so cool
While British-based Audient
is fairly new on the scene (1998) the company's founders have quite a long and respectable pedigree. Co-founder David Dearden
has worked with David Manley (original owner of Manley Laboratories) Eddie Offord (Emerson Lake and Palmer Yes) and was involved
in building a custom console and private studio for John Lennon for his Imagine sessions followed by studios for
George Harrison Ringo Starr Gus Dudgeon (producer Elton John David Bowie) and Chris Squire of Yes. After three years with
MCI and two years with Soundcraft David Dearden and Gareth Davies (also from Soundcraft) formed DDA (Dearden Davies Associates)
a maker of high-quality analog consoles. When DDA became part of the Klark Teknik Group he also designed the Midas XL200 live
sound console and did the initial concept and design of the Midas H1000 console. Midas consoles are generally acknowledged
by FOH professions to be one of the if not the best live sound consoles in existence. In 1997 Dearden rejoined with Gareth
Davies to form Audient whose products are typified by high performance intelligent ergonomics and transparent sound quality.
Notable users of Audient gear include Abbey Road Studios Pete Townshend's Eel Pie Recording and England's Royal Academy of
Music.
