Works great, better than expected, good unit does the job at a good price, only drawback it needs an ON/OFF Switch which it doesn't have. Need to unplug it after use or it stays powered on all the time.
Great product - perfect for hooking up a sub where you have to use the LFE input with a full bandwidth line-level signal as when paired with powered monitors. Design is well thought-out making gain and cross-over frequency easily tweakable.
