Description
RDL TX SERIES BALANCED - UNBALANCED CONVERTERS - Transformer
These modules are intended to interface consumer audio equipment with professional balanced-line circuits, providing galvanic isolation in addition by the use of transformers, to avoid ground-loops and thus reducing hum.
Included accessories: All models are supplied with a data sheet with installation details.
Optional accessories: For hardware to mount TX Series modules on surfaces, to panels, to DIN-rails and a rack-mounting panel, see 'RDL TX Mounting Accessories'.
TX-A2 - Balanced to unbalanced - Terminals, RCA (phono)
This converts a single, balanced, line input into two unbalanced outputs, with a reduction in level to suit the inputs of equipment such as consumer audio and video equipment, using a 'studio-quality' transformer for isolation. The front panel of the aluminium enclosure has a detachable terminal block for the input and two gold-plated RCA (phono) connectors for the outputs. Each output is coupled through an attenuation network that produces a nominal -10dBV level.
Input: +4dBu nominal, +22dBu max, detachable terminal block. Outputs: -10dBV, nominal. Response: 20Hz - 20kHz +/- 0.5dB. Distortion: 0.05%, 20Hz - 20kHz, +4dBu input; 0.01%, 1kHz. Dimensions: 61 x 76 x 40mm.
TX-A2D - Balanced to unbalanced - Terminals, RCA (phono) - dual
Similar to the TX-A2, this converts two balanced line inputs each into a single unbalanced output using two transformers, again with attenuation to suit consumer equipment. The front panel has two detachable terminal blocks for the inputs and two gold-plated RCA (phono) connectors for the outputs.
Technical specifications: As the TX-A2, except the following. Crosstalk: -80dB, 20hz - 20 kHz, referenced to -10dBV; -90 dB, 1kHz.
TX-AFC1F - Balanced to unbalanced - XLR3F, RCA (phono)
This converts a single, balanced, line input into a single unbalanced output, with a reduction in level to suit the inputs of equipment such as consumer audio and video equipment, using a 'studio-quality' transformer for isolation. The front panel has a 3-pole, female XLR connector for the input and a single gold-plated RCA (phono) connector for the output.
Input: +4dBu nominal, +22dBu max, 10k ohms. Output: -10dBV, nominal. Input balance: 85dB CMRR, 50-60Hz. Response: 20Hz - 20kHz +/- 0.1dB. Distortion: 0.06%, 50Hz - 20kHz, +4dBu input; 0.0015%, 1kHz. Dimensions: 61 x 76 x 40mm.
TX-AFC1M - Unbalanced to balanced - RCA (phono) to XLR3F
This converts a single unbalanced circuit, from, for example, the output of consumer audio and video equipment, to a balanced signal for use over longer distances and to avoid hum, since it uses a 'studio quality' transformer to provide galvanic isolation. The front panel has a single RCA (phono) connector for the input from the unbalanced equipment and a 3-pole male XLR for the output.
Input: -10dBV nominal, +22dBu max, 10k ohms. Insertion loss, input to output: 0.25dB, 20 ohms source, 10k ohms load. Response: 20Hz - 20kHz +/- 0.1dB. Distortion: 0.06%, 50Hz - 20kHz, -10dBV input; 0.0015%, 1kHz. Dimensions: 42 x 76 x 40mm.
