Amperes LS4808 8 ch Speaker Line Surveillance

Product Details:
LS4808 is new speaker line monitoring unit, with the new processor and measurement algorithm, they are now able to perform tasks faster with better accuracy. Additional features included were trigger monitoring, which can be linked to timer for pre-set times activation. Similar to its previous model, they provide reliable speaker circuit monitoring for ground leakage, short and open circuit using impedance measurement method, thus eliminating the use of blocking capacitors and end line resistors.
