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.
Main Features
• 12 Channel 1 into 4 (12 into 48) Active Mic Splitter
• Unique Input & Output configuration options
• Unity Gain signal path for ease of set-up

the gate. Each channel has fully variable controls for
Filter Frequency, Threshold and Release. Range is switchable
to provide either full muting (-80dBu) or a more subtle
level of signal attenuation (-20dBu). Two Attack modes
are available; Fast or Slow and Release is manually adjustable.
In-built sidechain 'auto-level-sensing' and Hold circuitry
ensure that false triggering and chatter are kept to a
minimum. High and Low pass filters are included and can
be used for wide range of frequency conscious gating applications.
A LISTEN facility allows the filters to be easily tuned
by ear. Each channel also has a sidechain insert with
front panel indication when an External Key jack is plugged
in. LED indicators are provided for Above-Below Threshold,
Bypass and Link. All inputs and outputs are electronically
balanced and can be switched between +4dBu and -10dBV

Enter Can-D. It’s simple really; Can-D delays your
headphones so that they match the sound from the speakers.
With delay times of up to 678ms, you can be 226m from
the stage and still wallow in the sweet sound of time-coherent
cans.
And if you like your cans exceptionally loud, you’ll
be happy to know that with Can-D’s substantial headphone
amplifier, 9 out of 10 engineers found full volume to
be 'unbearably loud'. *
Of course, Can-D is rock-solid and tour-proof; its internal
PSU and solid aluminium case ensure it’s ready for
anything you can throw at it. Or anything you can throw
it at.
