NVX XPLOC4 4-Channel 600W Adjustable Line Output Converter with Remote Turn On

First I ordered two 2-channel cheaper LOCs for a single digit price. But they weren't the solution. Instead I got more issues. Defect, no power, poor connectors and build quality. Now, with this unit here I have NOTHING to complain so far. It has power, is easily adjustable, the connectors are of good quality and overall the build quality seems to be fine, too. I didn't check the remote power circuit so far, because I use it at home for my receiver to have a wireless surround connection with some wireless audio transceivers. For that I do not need the remote circuit. Though, the LOC channels work just great! Buy!

The perfect sound system trigger. Great for amplifiers with a memory terminal. It allows the amp turn off/on with the system. Easy adjusting. So far very reliable

I did not get to hook up the item because I didn't like all the wires that were required to install it. I am sure it works fine but I was unable to test it out myself. It was a bit too much for me to have to rewire the system to get this product working.

Bought this to add a 4 channel amp while keeping the original head unit. My son and I wired up the NVX box behind the head unit according to the poorly written instructions. We started cutting in the speakers one at a time. Started with front left... no sound. So before we cut any more wires, I contacted NVX customer service and spoke with a technician. He said, “these XPLOC four channels are so new that I don’t know much about them but go ahead and try wiring up the front right speaker also”. So we did just that. Wired up both front speakers and hooked up the battery and poof, faint smell of fried electronics. At this point, the front left speaker is on and sounding great, unfortunately the right front had no sound. After some troubleshooting it was discovered the head unit had lost the right front channel. Ironic, coincidental or was the NVX a factory lemon. Anyway, we now have a nice new head unit and didn’t need the oversized, poorly assembled NVX box.

I purchased this to connect a powered subwoofer to my Sony stereo receiver. The new receiver didn't have a sub out connection but it did have A&B wired speaker connections. I connected the converter to the right and left B speaker connection on my receiver and then connected RCA Y splitter on the converter to run a single wire to the RCA connection on the back of the subwoofer. Abracadabra!!!! It works great!
