Crestron QM-AE 

 

QuickMedia™ Audio Extractor

 

NOTE:  When daisy-chaining Cresnet units, strip the ends of the wires carefully 
to avoid nicking the conductors. Twist together the ends of the wires that share a 
pin on the network connector, and tin the twisted connection. Apply solder only 
to the ends of the twisted wires. Avoid tinning too far up the wires or the end 
becomes brittle. Insert the tinned connection into the Cresnet connector and 
tighten the retaining screw. Repeat the procedure for the other three conductors. 

NOTE:  For larger networks (i.e., freater than 28 network devices), it may 
become necessary to add a Cresnet Hub/Repeater (CNXHUB) to maintain signal 
quality throughout the network. Also, for networks with lengthy cable runs, it 
may be necessary to add a Hub/Repeater after only 20 devices.  

For the QuickMedia transport, use CRESCAT-QM cable.  

When connecting multiple QM devices, the route between a QM origination 
point (transmitter) and a QM endpoint (receiver) cannot have more than two 
midpoints (e.g., QM-MD7x2 or other QM switchers).  

NOTE:  The QM-AE does not count as a midpoint device. It may be placed 
anywhere in the QM network because it only taps the audio portion of the 
signal. All video is passed through unaffected. Refer to the following diagram 
when configuring a QM network. 

NOTE: The QM-AE should always come before the QM-RX. 

The Crestron Toolbox (replacement for Crestron Viewport, you may continue 
use Viewport if desired) is a broad-based software package that accomplishes 
multiple system tasks, primarily using an RS-232 or TCP/IP connection between 
a PC and one or more Crestron control systems.  

You can use the Crestron Toolbox to: 

• 

Observe system processes. 

• 

Upload operating systems and firmware.
