Inovonics' "TVU" displays stereo audio level metering on the screen of a television video monitor. It is connected in-line with the video signal and inserts an annotated stereo bargraph image into a corner of the picture.
The level display may be positioned anywhere on the screen and is switchable between American "VU" and European "PPM" metering standards.
NTSC as shipped; capacitor change required for optimum CCIR operation
Bridging or 75-ohm-terminating; accepts 1-Volt p-p composite video with negative sync.
75-ohm source, delivers 1 volt p-p into 75-ohm-terminated load.
±0.5dB, 10Hz-10MHz; linear phase response over picture bandwidth.
Active-balanced, bridging; accommodate nominal “0VU” input levels between 0dBu and +15dBu.
Single-ended, bridging;accommodate input levels between-15dBu and 0dBu.
VU CALIBRATE (Input Gain) controls accommodate line level ranges noted above. PPM CAL controls offset PPM “zero” reference from zero-VU by -5dB to -13dB.
