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.

Frequency response: 10–35000kHz ±0.01dB
THD: <0.0025%
Headroom: >20dB above +4dBu input/output
Noise: <92dB below +4dBu output
Crosstalk: <-90 dB (20 Hz to 5 kHz); <-80 dB (5 kHz to 20 kHz)
CMRR: >90dB at 100Hz
Indicators: 2 LED per channel for audio present and peak
Power: 24–33V DC, 120mA

RU-ADA8D Distribution Amplifier

As per RU-ADA4D however capable of 2 x 8 stereo or 1 x 16 mono.


RU-MLD4 Mic/Line DA

For applications where connectorised, 4-channel, balanced mic or line level audio distribution is needed. The input and output connections are provided on the front panel as XLR and the rear panel as full-sized detachable barrier blocks and can wired balanced or unbalanced. The outputs are 150 ohms balanced, designed to drive short or long balanced lines, with each output switchable between mic and line level. Both the front panel input XLR connector and the rear panel input terminals are active at all times and are switchable between mic (high and low gain) and line level. Gain trim is provided on a front panel control, along with dual-LED metering, thus accommodating a wide variety of dynamic or condenser microphones as well as line level setup. 24V phantom power can also be selected for the microphone mode input.

Technical Specification:
Input connectors: XLR 3 pin female, detachable rear barrier block
Input level: Switchable on rear;
Mic: -48dBu to -3dBu (Low), -65dBu to -20 dBu (High)
Line: -15dBu to +28 dBu
Input impedance: Mic: 2k ohm balanced
Line: 10k ohm balanced
Output connectors: XLR 3 pin male, detachable rear barrier block
Output level: Switchable on rear; Mic -46dBu or Line +4dBu
Output impedance: 150 ohms balanced to drive high or low impedance lines
Gain trim: Mic (Low gain): Off to 52dB
Mic (High gain): Off to 69dB
Line: Off to 20 dB
Frequency response: Mic: 80Hz to 50kHz (±0.75dB); @ 20Hz (integral high pass filter)
Line: 15Hz to 50kHz (±0.1dB)
THD+N: Mic: <0.1%; Line: <0.005%
CMRR: Mic: >60dB; Line: >50dB
Noise: Mic: –79dB below -45dBu output (ref. 40dB gain)
Mic: –70dB below -45dBu output (ref. 60dB gain)
Line: –85dB below +4dBu output
Headroom: >20dB (above +4dBu Line output)
Supply input: 24–33V DC 80mA

RU-MLD4T

As per RU-MLD4 however includes transformer.


RU-UDA4 Unbalanced DA

This unit features two separate, isolated channels. The RU-UDA4 may be used in stereo applications, or as two individual mono distribution amplifiers. The input signals are buffered through output line drivers, providing 4 separate line-level unbalanced outputs for each of the two inputs. The RU-UDA4 performance is tailored around industry standard –10dBV input/output levels.

Technical Specification:
Input connectors: RCA (phono)
Input impedance 10k ohm unbalanced
Output connectors: RCA (phono), 4 per channel
Output impedance: 100 ohms unbalanced
Channels: 2 (left & right; may be used independently as 2 separate mono amplifiers)
Frequency response: 5Hz–50kHz (±0.5dB)
THD: <0.020%
Noise: <–90dB below –10dBV
Crosstalk: <–90dB @1kHz, <–80dB @10kHz, <–75dB @20kHz
Supply input: 24–33V DC 25mA

RU-VDA4B Video Distribution Amplifier

RU-VDA4B contains a 4 way distribution amplifier, each output capable of 1V peak to peak video signal into a terminated load. An indicator is provided to show the presence of such a signal. The input is a bridging type, with associated loop through output. Input gain is adjustable by means of a preset front panel control. All video connections are made using front panel BNC jacks, whilst the rear panel has barrier strip terminals for the necessary power input: 24V DC, 60mA nominal, (36V DC max). For suitable power supplies see RDL POWER SUPPLIES. This unit is part of a range of modules, mostly concerned with audio, which may be mounted up to 3 modules wide in a standard 19inch rack. See mounting options, listed within this group.

Input: 1 kohm (to bridge 75 ohm line). Gain: –1dB to +7dB. Load impedance: 75 ohms. Frequency response: 10Hz–10MHz ±0.2dB. Noise: <70dB below 1V p-p. Output isolation: >40dB. Differential gain: 0.1%. Differential phase: 0.1 degree. Video connections: BNC, unbalanced, ground referenced. Dimensions (WxHxD): 150×43×77mm.

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.
