RDL AV INTERFACES - RACK-UP Series

RDL Rack-Up series are 1/3 rack-width, rack-mounting modules, 1U high, offered with a wide range of functionality. Some Rack-Up modules are constructed in solid, encapsulated, durable, industrial, black plastic enclosures; Max Rack-Ups are assembled using heavy-duty, extruded-aluminium and steel panels. The rear panels have 'clear bold white lettering' for the terminal blocks and connectors. Reverse-printed, front-panel, poly-carbonate laminates provide a durable finished appearance for rack-mounted or free-standing use. Certain Rack-Up modules are often used free-standing; all Rack-Ups may be rack mounted by means of a range of mounting options, listed within this group.

RU-MLA2 Dual Mic/Line Preamp

This unit features two microphone or line level input and output preamplifiers which may be used in stereo applications, or as two individual mono preamplifiers. Inputs and outputs are available as front panel XLR and are also available on the rear panel barrier block. Features include input gain adjustment, mic/line selector switches for input and output, input level LED indicators (dual LEDs), mic input high/low gain selection. The outputs are low impedance balanced, designed to drive short or long balanced lines. Inputs and outputs can be wired balanced or unbalanced. 24V phantom power can also be selected for microphone inputs.

Powering

Powering: All units require a 24V DC power supply; each has both screw terminals and coaxial socket for power input. A ‘universal’ supply is available, 57-401, with 24V 3A output, which requires an IEC cord set. See RDL POWER SUPPLIES for more details. Note that all RDL modules with co-axial power input/output sockets use connectors with 2.5mm pins.
