Sonifex Passive Packs are a range of simple solutions using high quality transformers to change audio input/output impedances with level compensation and are an ideal, cost effective method of converting balanced to unbalanced and unbalanced to balance audio signals. 

Four models are available- 

1.SFX-CM-LUX1
Balanced to Unbalanced Converter, Passive, XLR to Phono 
2.SFX-CM-LUR1 Balanced to Unbalanced Converter, Passive, RJ45 (Analogue)to Phono

Provides an alternative to having to interface a balanced output to an unbalanced input via specialist cables (either by shorting the non-phase to ground or disconnecting it). Transformer balanced, with a 2:1 ratio, so 6dB of attenuation is added to the input to help interface with the lower signal levels associated with consumer outputs. 


3.SFX-CM-ULX1 Unbalanced to Balanced Converter, Passive, Phono to XLR 
4.SFX-CM-ULR1 Unbalanced to Balanced Converter, Passive, Phono to RJ45 (Analogue) 


Provides an alternative to wiring an unbalanced output directly into a balanced input. By placing this box close to the unbalanced output (before the cable run to the balanced input), the connection will benefit from the input device’s common mode rejection capabilities, reducing noise and interference. Transformer balanced, with a 1:2 ratio, so 6dB of gain is added to the input to help interface with the higher signal levels associated with professional outputs.
