Review on PAC LP3-2 L.O.C. PRO Series: High-Quality 2-Channel Line Output Converter by Robert Espinoza

I bought this unit to make it easier to add line out to our LeGrand OnQ digital whole house audio system. The individual keyboard amplifiers for each room do not share a common ground and only have speaker level outputs (no auxiliary outputs or line level outputs). Caution should be exercised when using such devices on non-standard floor amplifiers. Some designs use a very simple resistor circuit that can damage this type of amp. I removed this unit when I received it and was pleased to find that it uses transformer coupled circuitry, which is the correct method for non-standard ground amps. It works great and does exactly what I wanted. I use this unit to drive an extra 4 channel headphone amp in my music room. Now my musician friends and I can put on our headphones and play along with whatever is playing through our home audio system and actually hear ourselves and the music. Perfect for what I wanted to achieve.
