The MS424 is a 4 channel 1 into 4 Unity Gain Active Microphone
Splitter in a compact 1U self powered case. The MS424 is designed
for applications where multiple feeds are required from one set of
microphones without the signal degradation experienced with most
passive splitting solutions. The Unity Gain design philosophy
allows simple integration into existing systems without the need
for lengthy recalibration.
Each of the MS424 channels has an electronically balanced input,
which may be transformer balanced as an option, and four
independently transformer buffered floating outputs on XLR
connectors. Output one of each channel may be linked directly to
the input via a rear panel switch. The unit may also be
configured, by way of internal links, to feed 8, 12 or 16 outputs
from any one input, allowing the MS424 to be used for press box
applications.
The front panel of the MS424 gives access to outputs 3 and 4 as
well as phantom power switching with phantom presence LED, and Pad
switching for line level signals. The inputs and outputs 1&2 are
grouped on the rear panel together with the output 1 Link

MS1224 12x4
ACTIVE MIC SPLITTER SYSTEM £1,799.00 MS1224PS
POWER SUPPLY & MONITOR UNIT FOR 4 x MS1224
£499.00 MS1224PS-BU
BACK-UP POWER SUPPLY UNIT FOR MS1224 £499.00
The MS1224 is a 12 channel, 1 into 4 Unity Gain Active Microphone
Splitter designed for applications where multiple feeds are
required from one set of microphones without the signal
degradation experienced with passive splitting solutions. The
Unity Gain design principle combined with excellent line driving
ability ensures that unity levels are delivered at the end of each
feed, even over considerable distance, thereby saving time in
recalibrating levels.
Each of the MS1224's channels has four independently buffered,
transformer balanced outputs and a fifth dedicated parallel Link
output. The Link output may be used to provide a direct, non
active feed, for instance to the FOH console, or it can be used to
daisy chain adjacent channels to provide more output feeds from a
single microphone, for instance for Press Box applications. The
inputs are electronically balanced with a Pad switch for
connection of line level signals. Switchable Phantom Power is
provided with a Phantom Presence LED.
The MS1224 incorporates a channel monitoring circuit, which is
accessed on the PSU unit. Each channel has a Listen button that
connects it momentarily both to an LED bargraph and headphone
socket on the PSU front panel. The headphone monitor circuit
incorporates a dynamics enhancement and protection system. This
controls the dynamics of the signal in a way that amplifies very
low background levels whilst limiting high signal levels. This
enables monitoring of microphone function during set up without
the need of a vocalist being present on the mic. It also provides
user protection against sudden loud signals.
A unique design feature of the MS1224 is the option to configure
the way that Input and Output connectors are presented on the
front and rear of the unit. As each customer has their own views
on this we have given the flexibility of presenting the Input and
two Outputs on the front and three Outputs on the rear, or
vice-versa. In addition the Output designated as Link can be
positioned either below the Input connector, or the top connector
of the group of three Outputs. Thereby giving four possible
permutations. The required configuration can be specified ex-works
or simply reconfigured at a later stage.

The C400 is a professional 4 channel compressor that can be
operated as 4 separate processors or linked as two independant
stereo pairs. In Link mode, Channel 1 and 3 provide Master control
and 'rms summing' is used to ensure that signals from both the
linked channels affect compression equally. Each channel has fully
variable controls for Threshold, Ratio, Release and Gain. The
compression slope can be switched between Hard or Soft knee, with
Hard knee providing tight control of compression Ratio and Soft
knee a more progressive style of compression. Two Attack/Release
modes are available; Auto (program dependant) Attack/Release or
Auto Attack with manuallly adjustable Release. A low frequency
Program filter can be switched into the sidechain to reduce the
effects of bass heavy material causing over compression. Each
channel also has a sidechain insert jack. Gain Reduction is
displayed on an 8 segment LED bargraph. The Bypass and Link
switches also have led indicators. All Inputs and Outputs are
electronically balanced and can be switched between +4dBu and
-10dBV operating levels.
MX32B
CONFERENCE MIXER £499.00

microphones and one of three, switch selectable, mono or stereo
A/V sources. Video may be switched together with the audio
programme when fitted with the video I/O option. The MX32B is
designed for operation by non pro-audio users and so keeps
operation as simple as possible whilst retaining full features and
performance specifications.
The microphone preamplifier has a wide dynamic range with very low
noise and distortion. Each of the balanced Mic/Line inputs has a
pre-fade Insert point for additional signal processing such as
equalisation, compression or gating. On the front panel each
channel has Phantom Power switching, switch selectable Mic or Line
input, a Volume control and a Pan control to position the signal.
Priority switching allows one or more channels to take priority
over the remaining channels and the A/V source.
A 2 band EQ, Master level control and dual 10 segment LED output
metering make the MX32B quick to set up and operate. The unit is
