MOTU is a well-known professional audio hardware manufacturing company in the United States. It used to develop and produce 1394 and USB interface external professional audio equipment. V3HD is the first 1394 interface external high-definition video and audio interface box launched by MOTU, which supports high-definition 108050i/59.94i/24p/25p/29.97p, 72024p/25p/29.97p/50p/60p and standard definition PAL/NTSC, etc. Format, with HDSDI input/output, high definition component input/output, SDSDI input/output, standard definition component input/output, Y/C input/output, composite input/output and HDMI high/standard definition digital output and other video interfaces, as well as 8 channels Analog balanced audio input/output, 8-channel AES/EBU digital audio input/output, 8-channel optical digital audio input/output, etc. This interface box can not only be connected to Apple or WindowsPC through the 1394 interface, and be used with FinalCutPro5.1 or later or Adobe PremiereProCS3 for high-definition program editing, but also can be used as a video and audio signal converter to achieve real-time up-down conversion and conversion of high-definition/standard-definition signals. Real-time conversion of video/audio signals between different interfaces. At present, V3HD has been introduced to the country by LTECH as an agent. [DVCLUB] product evaluation room received the interface box and evaluated it at the first time.
1. Rich video and audio interface
V3HD is a standard 19-inch interface box with a height of 2U (3.5 inches, or 8.9 cm), which can be easily installed on a standard 19-inch cabinet. V3HD has the same style as the professional audio interface box launched by MOTU. The main color is black, and the various label letters on the front panel are mostly eye-catching white. The upper part is the audio signal display part, including the analog audio input volume display, and designation. Channel volume display, audio status display, etc. Below the front panel are the time code display area, the video status display area, and the menu adjustment area. In the menu adjustment area, the interface box status can be adjusted with the buttons and LCD screen. The lower right corner of the interface box is the 1/4-inch headphone output interface, the headphone volume knob and the main power switch.
2. V3HD high-definition non-linear editing interface box/full-function converter evaluation
The upper left of the rear panel is a variety of video input and output interfaces, including HDSDI input/output, high-definition component input/output, SDSDI input/output, standard definition component input/output, Y/C input/output, composite input/output and HDMI high / SD digital output, etc. It is worth noting that, unlike similar interface boxes of other brands, V3HD's SDI input/output and component input/output both provide two sets of high-definition/standard-definition interfaces. Because the interface box itself is an up-down converter, this design avoids cumbersome settings during the use of HD/SD multiplexed interfaces. In addition, both HDSDI and SDSDI provide two output ports for connecting multiple devices such as monitors and video recorders at the same time. V3HD also provides HDMI high-definition/standard-definition digital output interface, which can be connected to popular high-definition televisions, high-definition projectors and some professional monitors. Whether using these HDMI display devices in the production room for pre-monitoring or large-screen display at conferences and events, the built-in HDMI output of V3HD meets the needs of users.
On the right side of the rear panel are full of various digital and analog audio interfaces. The upper part is the familiar XLR Canon connector, and the lower part is the three 25-pin ports. V3HD provides 8 channels of analog audio input/output and 8 channels of digital audio input/output, but it can only be realized by connecting a special XLR canon interface cable through a 25-pin port, and the XLR canon interface can only realize 4 channels of analog audio input/output. And 4-channel digital audio input/output, but this is enough for most program productions. In addition to the above audio interfaces, V3HD also has 2 ADAT optical digital audio input ports and 2 ADAT optical digital audio output ports, each port can transmit 8 channels of 44.1/48kHz audio or 4 channels of 88.2/96kHz audio. In addition, it can also support 8-channel PCM uncompressed audio output through the HDMI interface.
It should be noted that both HDSDI and SDSDI input/output of V3HD support 8-channel digital audio embedding. As a professional video/audio interface box, V3HD also provides comprehensive video/audio synchronization and device control interfaces, including REF reference video input, LTC time code input/output, and Wordclockmaster digital synchronization signal input/output interface required for professional audio production. , And control the RS-422 port of video recorders and other equipment.
V3HD connects to Apple or Windows PC through the 1394a or 1394b port on the rear panel to realize the non-editing function. We noticed that V3HD has two 1394b ports. When one port is connected to a computer, the other port can be connected to other 1394b devices. That is to say, V3HD can be used as a 1394bHUB.
Of course, we can't ignore the AC power socket in the lower left corner of the rear panel, the working voltage is 100-240V.
