The VCM-88 is intended for installations that include church, boardroom, nightclub, or
anywhere remote control of individual levels is required. Control is accomplished by
Ashly?s RD-8 and RW-8 remote controllers, RS-232 control using Ashly?s Protea System
Software, Crestron or AMX touchscreen controllers, MIDI or DC control using external
potentiometers.
The VCM-88 is housed in an all-steel, 1RU chassis, and contains eight fully independent
VCA channels capable of limiting, remote level control and mixing. By itself, the VCM-88
functions as precise eight-channel limiter with recessed threshold adjustments on each
channel. In this configuration the VCM-88 is an indispensable tool for limiting signal level
presented to 8-Track digital recording applications.
When connected to a PC running Ashly Protea System Software, RD-8 or other controller,
the VCM-88 can control individual channel and master levels with a range of +20dB to -75dB.
The VCM-88 also has a master output jack providing a summed output of all channels,
allowing the unit to function as a fully-contained eight-channel remote controlled line level mixer.
Internal switching allows you to patch channels for signal routing and matrixing and select
channel pass through for cascading multiple units in parallel. Each channel may also be selected
to have separate input and output jacks or a single TRS insert jack.
Features include:
Eight Channels of Remote Level Control,
RS-232 Interface Connector,
MIDI In and Thru,
PC Control Using Protea System Software,
Internal Channel Patching for Flexible Signal
Routing and Matrixing,
Internal Selection of Crestron,
AMX, MIDI or RS-232 Protocol,
Internal Channel Pass Through for Cascading Multiple Units in Parallel,
Signal Present LED?s On Each Channel,
and RD-8, RW-8 Compatible.
Connections on the rear panel include: separate 1/4? TRS balanced
input and output jacks, 1/4? master output jack, 9-pin D-sub RS-232,
DB-15 pin female for DC control,
MIDI In/Thru, and XLR remote control data input.
The VCM-88 is the result of incorporating user feedback of Ashly?s popular VCX-80 into a
processor that can be easily configured to perform a multitude of audio matrixing, limiting or
remote level control applications.

Description
The alphaton Feedback-Controller FC-100 is a revolutionary product for every microphone application including wireless types. It can provide effective feedback control to any sound reinforcement situation. It can also eliminated string feedback in guitars and bass instruments which are equipped with piezo or condenser pickups. The FC-100 provides 6 to 10 dB of feedback protection by analysing the incoming signal, detecting the presence of feedback and then notching out the feedback frequency. The FC-100 relieves the sound engineer automatically. It works dynamically and eliminates a feedback signal before it can grow into a peak. Internally a discriminator circuit detects the presence of regenerative feedback and triggers the automatic equaliser to insert a notch where the feedback peak is coming up. This normally prevents other peaks from developing but if they do, the process is repeated at high speed, thus keeping feedback under control.

Psychoacoustic Bass Enhancement Unit with Renaissance Compressor, MaxxBass, and L2
Bass Boost for Live Sound, Broadcast, Mastering & Post Production
They say that in electronics there's no new technology - the only changes
will be in size and applications. Things will simply keep getting smaller
while doing more. This is certainly true in music (just think about what an
iPod can do), but as we design smaller playback systems with small speakers,
there are also some tradeoffs, particularly in music. Clever cabinet designs and
high-excursion drivers can get you only so far. Any audio engineer trying to extract
bass from real-world components must eventually face the laws of physics:
All things being equal, small boxes and speaker cones can't move enough air
to produce a room-shaking low end. When working with systems tiny enough to
toss in a shoulder bag, the challenge is even more formidable. Interestingly enough,
Waves MaxxBCL has a new solution to this problem using a very old concept.
Waves MaxxBCL at a Glance:
MaxxBass? Bass Enhancement adds deep bass sound without adding bass frequencies
Waves Renaissance Compressor
L2 Ultramaximizer Peak Limiter
24-bit/96kHz resolution with 48-bit, double-precision processing
Supports optical, coaxial S/PDIF, AES/EBU, balanced and unbalanced line-level analog signals
MaxxBass Bass Enhancement
Waves' patented algorithm adds stunning bass sound without adding bass frequencies,
delivering a bigger bottom end. MaxxBass? allows your audience to hear bass frequencies
lower than physically present by applying psychoacoustic principles: Even though we
can hear a bass guitar from a small speaker, we don't actually hear the fundamental
frequency because the speaker can't produce a pitch that low. Instead, we hear the
harmonics that the speaker can produce, and this causes the brain to create the "missing
fundamental." MaxxBass? takes this well-known psychoacoustic phenomenon to the
maximum, giving you the ability to extend the perceived frequency response of a system
about two octaves below its physical limitation.
To accomplish this, the signal is split: high frequencies are passed to the output (to be
added back to the bass). The bass signal is analyzed and a specific series of upper
harmonics are created. Because the dynamics of the original bass are duplicated in these
harmonics, the result is the most natural sounding bass enhancement available. The
MaxxBass? harmonics and the original bass can be mixed in any proportion at the output.
To provide more control, a high-pass filter can be switched in, allowing the harmonics only to
be passed along as an "image" of the original bass frequencies, which is useful when working
with a system with known low-frequency limitations to avoid over-excursion of the speaker drivers.
Renaissance Compressor
Designed to provide the classic warm sound of analog compressors, the legendary
Renaissance Compressor controls dynamics with studio-style warmth that flatters
full mixes, vocals, or instruments. Controls include selection of vintage-style Opto
or modern Electro compression, and threshold, ratio, and attack controls. Waves
ARC? (Automatic Release Control) algorithm dynamically optimizes the compressor's
release value for a wide-ranging input. ARC? reacts much the way a human ear
expects, and can produce increased RMS level with greater clarity.
In general, the release is faster for peak transients and slower for the overall RMS
level. The ARC? system varies the release time to fit the ear's expectations while
increasing RMS, and without creating distracting artifacts. In this way, the
Renaissance Compressor can serve as a leveler plus a fast compressor simultaneously.
L2 Ultramaximizer Peak Limiter
Heard on countless hit records and soundtracks, the L2 Ultramaximizer puts sound
up-front with breathtaking transparency. The L2 is capable of a very fast, overshoot-free
response. Once the limiter threshold has been set, you can define the actual peak level
that the processed signal will reach. Once set, limiting and level re-scaling becomes a
one-shot process. The L2 can significantly increase the average signal level without
introducing any audible side effects. Yet there is plenty of range to recreate "vintage"
effects such as level pumping or severely limited dynamic range if you like.
Pristine Sound Quality
The MaxxBCL offers 96kHz, 24-bit resolution with a 48-bit, double precision internal
processing path and a dynamic range of ~125dB. The totally passive analog input
path to the ADC uses Jensen transformers, while the output path also features Jensen
analog output transformers. The unit is galvanic-isolated, which prevents ground loops
and allows it to operate in electrically unstable environments. Waves MaxxBCL combines
the highest quality converters available with unequalled processing algorithms to offer you
astonishing new power in bass enhancement, dynamics processing, and format conversion
(analog-to-digital, digital-to-analog, and digital re-quantization).
Versatile Connections
The MaxxBCL supports optical, coaxial S/PDIF, AES/EBU, balanced and unbalanced
line-level analog signals. MaxxBCL features a unique set of input and output trim settings:
analog input headroom can be set from 9dB above 0dBu to 24dB in six precise steps
(using the rear-panel selectors). Analog output level is similarly set with a separate
rear-panel trim pot offering you the ability to connect between devices with a wide range
of input and output levels.
