ctive Mic Splitter System

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
• Drives long cable runs without level loss
• Compact design, 48 channel System in 13U
• Channel Monitoring facility

Headphone Delay

CAN-D HEADPHONE DELAY £225.00
You’re mixing FOH for a gig. That means the speakers are over there, and you’re over here. Is it any wonder that your headphones sound confusing?

We all know that even short distances cause time delays. As a consequence, listening on headphones when you’re any distance from the stage will leave you with a confused mess of direct and delayed sound.

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.

Loud and clear… sweet. Can-D

*HEALTH WARNING: Your hearing can be permanently damaged when exposed to excessive sound levels, especially when combined with prolonged listening periods. Listen sensibly.

Key Features:
• Stereo delay – up to 678ms
• Powerful headphone amplifier
