LA Audio: MS1224
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 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. LA Audio: G400
