Page 5: Quickmedia™ Distribution Amplifier: Qm-Da
Crestron QM-DA QuickMedia™ Distribution Amplifier: QM-DA Introduction The QM-DA-4, QM-DA-8 and QM-DA-16 are QuickMedia™ (QM) distribution amplifiers designed to distribute a single QM signal to up to four, eight or 16 QM receivers. (The QM-DA-4 has four outputs, the QM-DA-8 has eight outputs and the QM-DA-16 has 16 outputs.) All signal distribution is provided over inexpensive CAT5e type cable via Crestron’s exclusive QM transport, supporting high resolution RGB, video, stereo audio and microphone signals up to a total distance of 450 feet... -

Crestron QM-DA Setup Network Wiring When wiring the network, consider the following: For more details, refer to “Check Network Wiring” on page 13. QuickMedia Wiring The Crestron QuickMedia cable (sold under the name “CresCAT-QM”) contains one CAT5E cable and one Cresnet cable in Siamese jackets. Installation of any QM device is as simple as installing CresCAT-QM wires from the output of one device to the input of another. -
Page 12: Installation
QuickMedia™ Distribution Amplifier The aggregate cable length of a signal path originating at a QM transmitter and terminating at a QM receiver must not exceed 450 feet (137 meters). Video signals may experience a loss of quality over very long lengths of cable. This phenomenon is due to the added resistance and capacitance of longer cable lengths and is not peculiar to either Crestron and/or QuickMedia systems. - Page 13 Crestron QM-DA WARNING: To prevent bodily injury when mounting or servicing this unit in a rack, take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety: NOTE: If rack mounting is not required, rubber feet are provided for tabletop mounting or stacking.
