CXL-4160 100v Line TX Module

A range of multipurpose transformers, all with screw terminal connections, housed in plastic enclosures. These can be mounted in the conventional “Stick on” method, or using the MB-1 mounting kit. Dimensions of all units 76 (l)×30 (w)×36 (d) mm.

TX-8A Audio Transformer

Used to add transformer coupling between a single channel, mono 4ohm or 8ohm power amplifier to line-level a mixer or amplifier. Frequency response 20Hz-20kHz ±0.75dB. THD <0.1% (ref. 1kHz). A rotary level controller allows adjustment of -10dBV or +4dBu. Balanced/unbalanced output.

TX-J2 Audio Transformer

Used to mix two unbalanced audio signals on RCA (phono) to single balanced mono output without gain. Frequency response 30Hz-20kHz ±0.5dB. Hum cancelling is add to unbalanced audio inputs. Balanced output.

TX-10B Bridging Input Transformer

Used to add transformer isolation to any line-level RDL product input. Frequency response 20Hz-20kHz ±0.5dB. THD <0.05% (ref. 1kHz). 10k input bridges any audio line. Balanced input and output.

TX-1A Adjustable Line Transformer

Provides transformer isolation between balanced line and unbalanced input. Level trimpot adjusts output 4dB to 24dB below input level. Input may be 10k bridging or 600R terminated. Frequency response 20Hz-20kHz ±0.5dB. THD <0.05% (ref. 1kHz).

TX-70A Speaker Level Transformer

Matches a 100, 70 or 25 volts speaker line to any unbalanced line-level audio input. A trimpot adjusts output level for various input voltage/power levels. Frequency response 20Hz-25kHz ± 0.5dB. THD <0.05% (ref. 1kHz).

TX-LM2 Line Matching Transformer

Matches unbalanced 600R phone or other line into mic or line input. Dual outputs, unbalanced line level or balanced mic level. Frequency response 20Hz-20kHz (±0.5dB. THD <0.05% (ref. 1kHz).

TX-AT1 - 600 ohms, 1:1

This transformer has 600 ohm primary and secondary, though is optimised to be driven from a low-impedance source into a bridging load. The primary and/or secondary may be wired unbalanced, providing conversion between balanced and unbalanced audio lines. The front panel has five screw-terminals, two each for input and output, and one for ground.

Input: +4dBu nominal, +22dBu maximum. Input balance: 85dB CMRR, 50-60Hz. Response: 20Hz - 20kHz +/- 0.1dB. Distortion: 0.035% THD, 50Hz-20kHz, +4dBu input; 0.001%, 1kHz, +4dBu input, 0.09%, 20Hz, +4dBu input. Insertion loss: 0.25dB, 20 ohms source, 10k ohms load; 2dB, 20ohms source, 600 ohms load. Output: As input, less insertion loss. Dimensions: 48 x 41 x 76mm.

TX-AT1S - 600 ohms, 1:1- HF and transient suppression

This is similar to the TX-AT1, with, in addition, 'surface-mount, solid-state, transient suppression technology coupled with ferrite high frequency suppression' intended to reduce the effects of 'harmful impulses' and 'unwanted RF pick-up'.

Connections and technical specifications are as the TX-AT1S except the following. Maximum interference signal: 30Vp, 60 Vp-p. HV switch clamp: 24V actuation; 48V maximum clamp. Transient energy: 0.1 joule.
