Connectronics digital audio patchbays, loaded with Neutrik digital converters provide an excellent impedance transformer at a reasonable cost for meeting the needs between analog and digital applications. Their use also allows for longer cable runs via unbalanced coaxial lines rather than twisted pair cables that present high attenuation values at the relevant frequencies.
The criteria for these patchbays are:
Impedance matching between 75 Ohm and 110 Ohm
Transition of balanced/unbalanced circuit (balun)
Electrical isolation (optional, not necessary)
Reduction of hum and noise
