Excellent for component video + stereo audio or 5.1-channel audio switching
on July 26, 2010
I first bought this switcher for its intended purpose, selecting one of four component-video inputs with stereo audio, and have always been quite satisfied with it. I like it especially for the video quality and value. The video quality is good enough to notice the subtle difference among three different DVD players (see below), and to preserve the full and clear superiority of HD (1080i) sources such as BluRay, HD-DVD, and HDTV tuner, with zero perceptible noise or distortion, so I rated it as Excellent. My only quibble is that the selected channel is indicated by red LEDs that are somewhat dim and hard to see at an angle.
Last year, I purchased another Monoprice component-video switcher, but this time for use as a 5.1-channel audio switcher, since I had meanwhile acquired four components with multichannel audio but had only one set of 5.1 inputs on my AV receiver. This second unit also works quite well, although there is an audible high-frequency switching noise when changing inputs. Once switched, however, audio quality seems perfect. The only slight issue is that it seems the jacks may have become a bit loose due to the stress of connecting and disconnecting some very tight, heavy-gauge audio cables. (Darn those high-end Monster Cables! I now much prefer AR, Tendon, or Atlona brands.)
By the way, I am not sure, but I *think* there is no problem using the video switching circuitry for audio signals. If anyone knows if I am losing or risking something, please advise. As I understand it, the main difference between RCA video and audio cables is that video cables & circuits have a much more narrow tolerance for the impedance specification (75 ohms). RCA component video signals may also be more susceptible to interference, since they are usually thicker cores and shielding than standard-grade audio cables.
