| 204 |
207 The
Model 204 is a professional two channel audio
processor, where each channel independently has an Aphex Aural
Exciter® section and an Optical Big Bottom® section.
The unit therefore may be operated on a stereo pair or as completely
separate channels for use in mixdown sessions — or any
other audio use only limited by your imagination.
BENEFITS
Aural Exciter Big Bottom
Increased Presence and Clarity Deeper, More Resonant Bass
Restores Natural Brightness Little or No Increase in Peak Output
Greater Perceived Loudness Tighter Bass Articulation
Improved Detail and Intelligibility Extended Low Frequencies
The Model 204 DRAMATICALLY enhances live, recorded, broadcast
and webcast sound. The patented Aural Exciter enhances detail,
clarity and imaging. It has even been scientifically proven
to increase intelligibility. It pulls a vocal or an instrument
up out of a mix. It punches up an entire mix, even in a noisy
or reverberant environment. The new Optical Big Bottom adds
low-end punch with deeper, more powerful bass. This enhanced
bass can be packed into your tracks without overloading the
recorder and into your PA system without adding more amps or
speakers. You
cannot achieve these improvements with any other processing
regardless of price. There are many "enhancers"
on the market, but none can match the effectiveness and musicality
of the patented processes in the Model 204.

| 250 |
 The
Aphex Aural Exciter Type III 250 utilizes a
patented audio process that will recreate and restore missing
harmonics. These harmonics are musically and dynamically related
to the original sound. When added, they restore natural brightness,
clarity and presence, and can actually extend audio bandwidth.
These harmonics are so low in level however, they add little
power to the signal. Unlike an equalizer or other "brightness
enhancers" which can only boost high frequencies, the Aural
Exciter Type III extends the high frequencies. It is a single-ended
process that can be applied at any point in an audio chain,
and needs no decoding.

The Process
The Aphex Aural Exciter Type III utilizes a patented audio
process that will recreate and restore missing harmonics.
These harmonics are musically and dynamically related to the
original sound. When added, they restore natural brightness,
clarity and presence, and can actually extend audio bandwidth.
These harmonics are so low in level however, they add little
power to the signal. Unlike an equalizer or other "brightness
enhancers" which can only boost high frequencies, the
Aural Exciter Type III extends the high frequencies. It is
a single-ended process that can be applied at any point in
an audio chain, and needs no decoding.
The
Aural Exciter process consists of two audio paths. The main
path and the process sidechain path. The main path transparently
conveys the audio signal directly from the input stage to
the output stage, maintaining unity gain with wide dynamic
range. The sidechain path contains all of the Aural Exciter
processing circuits and receives audio from the input stage.
A
mixing circuit in the main path allows the sidechain output
signal to be mixed with the main signal. The user adjusts
the amount of "MIX" to set the strength of the effect

| 320A |
 The
Aphex Model 320A delivers intelligent compressor
action, leveling and peak limiting simultaneously. This intelligent,
versatile and highly affordable processor can be used to solve
audio level problems and improve audio signals in the broadcast
studio, recording studio, tape duplication house, film dubbing
studio and in live sound applications. Patented control circuits
include analog computers that continuously analyze the input
signal and vary the control characteristics to provide for virtually
undetectable operation, regardless of the dynamics of the program |
|
| 320D |
Aphex 320D Since the introduction of the original
Compellor in 1983, no other audio level controller has met with
such success. Around the world, in broadcasting, recording,
or sound reinforcement, the Compellor is specified more than
any other level controller.
GET THE BEST OF BOTH WORLDS!
DUAL MONO OR STEREO
The 320D converts between acting as two independent mono processors
and one linked stereo processor by front panel selection. This
is true with both analog and digital I/O.
|
|
| 323A |
The Aphex Model 323A represents the most recent
iteration of the popular Compellor / Aural Exciter, a single
channel dynamics processor and program enhancer. The model 323
A permits absolute control over program dynamics, a benefit
made possible by the patented Compellor processor. The Aural
Exciter section enhances and restores program material, resulting
in increased audio presence, intelligibility, and articulation.
OPERATIONAL FEATURES
A significant improvement in this version of the Compellor /
Aural Exciter over its predecessor is the addition of a newly
developed (patents pending) Frequency Discriminate Leveler (FDL)
circuit. Exhaustive research by Aphex engineers led to the discovery
that, under conditions of program leveling, the human ear perceives
the onset of low frequency (bass and percussion) transients
differently than transients at higher frequencies. This perception,
as it turns out, is a direct function of the relative attack
time of the leveler. Without FDL, there is a significantly greater
chance that low frequency transients can create an audible "bass
pull back" effect. In addition to potential loss of bass
and/or low end "punch", mid and high frequency processing
can be negatively impacted. To the listener, the effect can
at times be heard as a perceived loss of bass or even a pumping
effect at the mid and treble frequency ranges.
FDL eliminates
this problem causing low frequency transients to generate
a slower attack time on the initial transient. High frequency
leveling is still controlled within the attack time determined
by the onboard computer. From the listener's standpoint, the
benefits are:
No more bass pullback effect Fast leveling can be used in
more applications
More bass punch for better music mixes Reduced audio distortion
in the leveling mode

| 661 |
 The
Aphex Model 661 is a totally new type of compressor
incorporating vacuum tube technology with the latest innovations
in audio compression. This single-channel compressor/limiter
is loaded with features, consolidating for the first time in
one rack space, three patented Aphex circuits: Tubessence®,
Easyrider®, and High Frequency Expander®.
The UNIQUE 661 CIRCUITRY
Tubessence is a true tube circuitwhich provides that "vintage"
tube sound without high the heat, bulk, short life, fragility,
and sonic variability found in traditional tube designs.
Easyrider
is an Automatic mode that actually works, consisting of the
Wave dependent Compressor™ (WDC) circuit which takes
the guesswork out of compressing individual instruments and
vocals especially in live mixes. WDC automatically adjusts
attack and release times according to the complexity of the
program material. Its No-Knee™ compression curve makes
the transition into compression virtually invisible.
In the
Manual mode, the Model 661 provides the full complement of
compressor adjustments such as Ratio, Attack, and Release,
for maximum flexibility. Express yourself and get those "punch",
"slap", "fat", "pump", and "squeeze"
sounds fast and clean.
The 661
includes the patented High Frequency Expander® (HFX) which
decompresses high frequencies, with user-adjustable ratio
and corner frequency. Add "life" and "air"
to your compressed signals without fear of background noise
pumping.
The Spectral
Phase Refractor™ restores clarity and punch to your
tracks. Bass frequencies are more defined with more apparent
power. Higher frequencies also seem to gain more detail and
presence.
Use the
Model 661 to control dynamics for mixdowns, protect your sound
system's loudspeakers from transients and distortion or shape
the sound of individual instruments and vocals. Compress dynamic
levels without fear of reducing frequency response. Whatever
type of dynamics control you're looking for, it can be done
with the Model 661 Tube Compressor / Limiter Expressor

 1100
Class A Tube Mic Preamp with 24/96 A/D
This superbly crafted new breed of advanced tube microphone
preamp reaches far beyond mere technical excellence to deliver
sound that is uniquely involving, compelling, and real. Our
incredible new 2 channel Model 1100 gives you up to 20 dB more
headroom than conventional preamps, allowing you to record hotter
tracks with the highest possible digital resolution. This unprecedented
amount of headroom, combined with an EIN of -135 dBu, allows
you to take more gain without the pain of overload distortion
or noise.
MORE GAIN - NO PAIN
To achieve this amazing performance, we developed new proprietary
circuitry:

relays |
|
| 1788 |
 The
Model 1788 contains eight preamps in 2RU space.
Since there is a fair amount of heat dissipation, there should
be at least 1RU spacing between every preamp. In that configuration,
they may be stacked to provide 40 channels of high quality preamps
in a standard 16RU road case.
Microphone Output Limiter - All preamps have a maximum input
level. Once that level is exceeded, there is no way to remove
that very unpleasant distortion. In order to avoid that occurrence,
many engineers set the preamp so that the expected peak level
at maximum sound level is still at least 12dB below the clip
point. While this provides some insurance against the preamp
clipping, it causes a loss of noise performance and, in the
case of digital, a loss of resolution. The Model 1788 has a
unique limiter (patent pending) in the front end of the preamp
which limits the output level of the microphone by as much as
20dB, hence the name 'Microphone Output Limiter'. This allows
the engineer to get maximum noise performance and also allows
maximum resolution for an analog to digital converter, all without
worrying about crashing the preamp.
26dB Pad - The Model 1788 has 39dB of adjustable input gain
and fixed gain of 26dB for a total maximum gain of 65dB. There
is a 26dB pad which will allow a preamp to be run as a unity
gain buffer stage. For example, this allows the line level output
of a wireless mic receiver to be fed into the preamp.
Adjustable Maximum Output Level - The maximum output level of
the Model 1788 is +24dBm (loaded into 600 Ohms) balanced. There
are, however, many input stages which have odd maximum input
levels (e.g.-+18dBu). In order to retain the function of the
microphone limiter and maximize noise performance of the entire
audio system, the Model 1788 has output level trim of up to
24dB. Once the maximum input level of the device following the
Model 1788 is defined, the output level of the 1788 can be trimmed
to that exact level. The input gain of the 1788 is then adjusted
to achieve optimum performance. In addition to the 24db of output
adjustment, each output may be muted.
Separate Analog Outputs - Microphones are often passively split
and then fed to two or more locations. The Model 1788 has two
separately trimmable, buffered analog outputs. The main output
on XLR is transformerless servo-balanced and the second output
is tranformerless balanced on a DB25 multipin connector. This
allows two separate inputs to be fed at optimal levels from
an optimized mic preamp.
Digital Option - In addition to the analog outputs, the Model
1788 has three optional digital outputs. The analog to digital
converters are 24 bit with selectable sampling rates. The sampling
rates can be generated from an internal clock or an external
source. The Model 1788 employs a drift stabilized A/D converter
circuit ( patent pending) which eliminates DC from the output
without incorporating a digital high pass filter. The digital
outputs appear on two DB25 connectors, one for AES/EBU and one
for the T/DIF format. There is also a TOSLINK optical output
for the ADAT format. There is an AES/EBU input on an XLR and
a Word Clock on a BNC connector for external clock input. If
the unit is being used as a master there is an AES/EBU output
on an XLR.
Test Tone Generator - There is a 700Hz test tone at two different
levels which can be bussed to any selected preamp channel. The
two levels are at 0dBfs (maximum output level) and -20dBfs.
The test tone at 0dBfs allows easy set up for finding maximum
peak input into following stages. The -20dBfs tone is useful
for digital systems which use a -20dB reference tone for '0Vu'.
Display - The Model 1788 has LED indicators for the status of
each function for each channel. A twelve segment LED meter displays
headroom. Two eight segment LED's show input gain or maximum
output level on either of the two analog outputs. All indicators
and metering can be monitored at the remote location.
Headphone Output - As an additional feature, the Model 1788
has a front panel headphone output. Any channel can be selected
and the output level adjusted.
The Model 1788 Microphone Preamp and Model 1788RC Remote Controller
form a complete Microphone preamp system with both analog and
(optional) digital outputs available simultaneously.
The Problem
Why place the preamp near the Mic? Long mic level lines, mic
splitters, and multiple inputs reduce the sensitivity of the
microphone and change its frequency, phase, and transient response.
This performance degradation is the result of shifts in impedance,
capacitance, and inductance values and is quite audible.
Phantom
power on a mic line causes the line itself to become a microphone.
Jiggling the line will create audible affects. Having the
phantom power source as close as possible to the microphone
also reduces the chance of phantom voltage loss within a very
long cable run.
Most modern
preamplifiers have excellent common mode rejection ratio,
often approaching 110dB. If there is common mode signal (noise)
built up in cable run and the gain of the preamp is 60dB,
the residual common mode noise is only 50dB down. While common
mode signal can be present in a short line as well as a long
line, there is a higher probability that there will be more
common mode signal in the longer line, especially if that
line is crossing power and lighting cables and a high RF field.
The Solution
By placing the 1788 close to the mics and controlling it remotely
the need for long mic level runs is eliminated.
The noise picked up by long cable runs is no longer boosted
at the end of the lines since the preamp gain has already
been taken at the input of the line.
By providing 5 outputs (2 Analog and 3 Digital) that are usable
simultaneously, the need for splitter boxes is eliminated.

Our Press
The Model 2020 was hailed worldwide as the FM processor of
choice for stations where sound quality and loudness are equally
important. Review after review talked about "clarity",
"naturalness", "loudness", "lack
of annoying artifacts", "great value", "deep,
rich bottom end", "clear, unclouded midrange and
highs" — the list of accolades went on and on.
Now with new circuit designs, improved processing algorithms
and new features the reviewers will have to find new superlatives
for the 2020MkIII.
Loudness vs Cleanliness
Competition for loudness impacts audio quality. The 2020MkIII
rewrites that formula through the utilization of 18 exclusive
techniques (patented and patent pending) which increase density
beyond any other processor while retaining naturalness and
musicality.
Increased Coverage
Another advantage of the 2020MkIII is the stability and purity
of the signal, resulting in extended coverage in shadow areas.
Customize Your Own Sound
The 2020MkIII comes with 8 sample presets that many will find
perfect for their station's sound. Others will find these
suitable as the starting point to completely customize a sonic
signature from the vast palette of control over processing
parameters.
Remote Control
The Model 2020MkIII is totally controllable locally via the
front panel controls or remotely via RS232 and modem. The
newly improved Remote Software is Wintows™ 98/2000 compatible.
