Henry Engineering tells Radio World that it will debut its new Stereo Audio Monitor, or SAM, at NAB.
This is a digital audio level and phase meter. The SAM uses Single Stereo Display technology, for which a patent application is pending, to display both channels of a stereo signal using only one LED meter.
“The SSD meter utilizes tri-color LEDs, showing the Left channel in green, the Right channel in Red, and both (L+R) channels displayed in yellow,” Henry states. “By watching the Single Stereo Display, an observer can easily read the levels of both audio channels, see the balance between the channels, and instantly see if a channel is missing.”
It also uses a second Single Stereo Display to show the Sum (L+R) and Difference (L-R) components of a stereo signal. “An observer can see if excessive L-R levels could indicate phase error or a polarity reversal in the audio chain.”
SAM accepts either an AES/EBU digital input or analog inputs. It accurately indicates system levels over a range of –25 to +3 VU. A headphone jack is provided for aural monitoring.
