TrueMatch RMC Technology

Controls

The TrueMatch RMC is designed as stand-alone unit and hardly requires the user‘s attention in operation.

For the version equipped with microphone-input boards, parameters such as input sensitivity, subsonic filter, phantom power, and phase inversion are set using the digital encoders on the front panel. The line-input sensitivity can be configured using an external control computer; the setting will then be stored to the device itself.

The output levels are displayed via the analog-like LED arcs.
An external signal fed to the wordclock input is immediately recognized and indicated on the front panel. If the sync source fails, the previous sync frequency will be generated internally and thus maintained; the device will directly change to internal synchronisation. The frequency setting will be memorized when the device is turned off and will be recalled immediately after switch-on again.

PC Interface

The configuration options are enhanced when using a standard IBM-PC or compatible. The control program running on the computer can access the parameters of the Reference Mastering A/D via the serial interface. A version including an RS422-interface port for spanning larger distances can be supplied on request.

The following settings can be viewed and changed:

• free I/O routing, storable
• sample rate
• peak-level indication for individual channels
• shared multi-channel meters for all channels
• routing of the internal test-tone generator
• phase inversion for individual channels
• settings of the XMAD board such as gain, subsonic filters, and phantom power
• AES/EBU output format (professional/consumer)
• output parameters for other formats

Technology

TrueMatch RMC has a modular structure and consists of I/O modules for the respective audio formats. System control and operation are performed using additional modules that may also be used for communicating with an optional configuration computer. All modules (including the power-supply unit) are made as slot boards and are mounted in a 19" carrier frame (3 U).
All standard connectors are available on the rear panel of the device, thus avoiding a need for special adaptors.
Input and output boards can be replaced during operation (hot swap). Failure of any board does not affect the remaining boards.
Particular features such as the combo XLR/line connectors or handy operation smooth the user‘s everyday work.
