The AUDAC TR266 is a super shielded true isolation audio transformer which is especially designed to be used in highly polluted EMI environments. Hum in audio systems is usually caused by ground loops in the system. A common mode current will flow in a ground loop created by an electrical system that has grounds on different voltage potentials. This results in a 50 Hz hum in the audio signal.The most common method to solve these problems is an audio transformer. The AUDAC TR266 audio isolation transformer with an in- and output impedance of 600 Ohm and a turns ratio of 1 : 1 has a very wide bandwidth and very low distortion which ensures a non distorted bass response and non attenuated high frequencies. Thanks to its MU-metal shielding, it can guarantee the best performance in even the most EMI polluted environments. MU-Metal is a soft ferromagnetic material with a very high magnetic permeability. It consists of an alloy of Nickel, Iron, Copper and Molybdenum. MU-Metal has a magnetic shielding effectiveness going from 100x up to 1000x higher than steel of equivalent thickness. It is especially good in 50/60hz type applications where all other shieldings fail. The TR266 super shielded transformer can be used for applications where the shielding of standard transformers becomes inadequate. A typical example of such an application is the broadcast system in railway stations.

The WP523 is a remote wall mixer which is meant to be used in combination with the LX523 active speaker system. It converts the signal coming from a stereo line-level audio source (such as CD-player, tuner, MP3 player, … ) or balanced microphone to the level corresponding the differential signal input on the LX523 (RJ45) making it possible to transfer high-quality audio over long distances between the wall panel and the loudspeaker, by just using inexpensive twisted pair CAT5 cabling. On the front side of the wall panel, there is a stereo RCA line input available together with a balanced XLR microphone input, both provided with their own knob which allows the signals to be mixed together. A main volume dial allows you to adjust the overall volume of the loudspeaker system. The mixing potentiometers are level with the surface and both equipped with a Push-Lock mechanism. They can be opened and hidden again by pressing it. An internal limiter avoids distortion on the input signal and intervenes when the level of the input signal reaches the clipping level. The ‘Clip’ LED located above the mixing potentiometer will illuminate when it’s recommended to reduce the level. This should be done by turning back the potentiometer. A jumper on the rear side of the panel allows you to enable the 12V phantom power for the microphone input. The connection of the wall panel should be done with twisted pair UTP CAT5 cabling whereby distances up to 500 meters can be reached. It should be connected to the 8-pin Euro-Terminal Block connector on the rear side of the panel. Available in black (/B) and white (/W).

The WMI are flush mountable Wall Microphone Input Units, which can be integrated into several kinds of installation materials for system integration. They are fitted with a Female XLR input connector on the front side and a terminal block connector on the rear side. The signal which is applied to the input connection is converted to a differential signal with increased voltage levels. This way, the signal is made insensitive to interference and noise and can be transferred over a long distance without any loss of quality. This allows reliable signal transmission up to 300 meters over CAT5E (or better) twisted pair cabling. A jumper on the rear side allows enabling of 15 Volts phantom power. It should be used in combination with a matching device on the receiver end.
