ASHLY VCM-88 8-CHANNEL MATRIXING LEVEL CONTROLLER

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.

The S com 4 is a compact and versatile single-rack space device that provides
four channels of high quality dynamics processing with an Expander/Gate and
Compressor/Limiter on each channel.
The four channels operate independently or in stereo pairs. Its multi-segment LED
metering displays input/output level as well as gain reduction. The Expander/Gate
section features a continuously variable Threshold control as well as a switch for
fast or slow release times.
The Compressor/Limiter section includes variable Threshold, Ratio and Output levels.
S com 4's Enhancer switch restores high frequencies that are sometimes diminished
by heavy compression. This wide-ranging combination of features makes the S com
4 an efficient and versatile audio tool for a wide variety of applications. Its clean and
quiet audio characteristics make it ideal where high sonic integrity is imperative.
