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.
In keeping with our policy of continuous improvement LA Audio reserves the right to alter specifications without prior notice.
