Low Z Speaker Installation Patch Box

• Many installed sound systems work with 4, 8 or a maximum of 16 speakers, and serve relatively limited areas of up to 300sqm, with the main target of music replay.
• Typical installations of this nature encompass retail shops, restaurants and bars.
• While contractors tend to choose 100V line systems for such applications, such choice increases the cost and decreases the efficiency and specifically the sound quality of a sound system, since expensive transformers with limited audio bandwith and high saturation losses are inserted in the signal path.
