3 Overview
The 713 and 714 are a TP (Twisted Pair) transmitter and receiver for composite
video and unbalanced stereo audio signals. The 713 transmitter converts composite
video and stereo audio into a Twisted Pair (TP) signal and the 714 receiver
converts the TP signal back to composite video, stereo audio and also provides an
S/PDIF digital audio output.
The 713/714 feature:
• A system range of up to 1600m (5300ft), depending on the model
• Audio transmission in broadcast quality digital audio format (48kHz/24bit)
• Automatic audio and video equalization (EQ) control (714)
The 713 and 714 are part of the Kramer TOOLS™ family of compact high-quality
and cost effective solutions which are fed from an external 12V DC source, making
them suitable for field operation.
To achieve the best performance:
• Connect only good quality connection cables, thus avoiding interference,
deterioration in signal quality due to poor matching, and elevated noise
levels (often associated with low quality cables)
• Avoid interference from neighboring electrical appliances and position your
Kramer TOOLS™ away from moisture, excessive sunlight and dust
3.1 Shielded Twisted Pair/Unshielded Twisted Pair
We recommend that you use Shielded Twisted Pair (STP) cable. There are
different levels of STP cable available, and we advise you to use the best quality
STP cable that you can afford. Bear in mind, though, that we advise using STP
cables where possible, since the compliance to electromagnetic interference has
been tested using STP cables.
Although Unshielded Twisted Pair (UTP) cable might be preferred for extended
distance applications, the UTP cable should be installed as far as possible from
electric cables, motors, and so on, which tend to create electrical interference.
However, since the use of UTP cable might not conform to electromagnetic
standards, Kramer does not commit to meeting the standard with UTP cable.
Note: There is no requirement and we do not recommend the use of skew-free
cable.
3.2 Power Connect
The Power Connect™ feature does not apply to the 713 and 714.
