Sennheiser will announce the availability of the Command Channel option on the SKM 5200 handheld microphone transmitter (pictured), the EK 3241 portable receiver and the EM 3532, 3032 and 1046 rackmount receivers at NAB 2007 in Las Vegas (April 16-19). The Command Channel function provides a second audio channel between the transmitter and receiver that permits a variety of secondary functions to be implemented for broadcast and live performance applications.
When the Command Channel option is installed on the receiver and the B5000-2 Command battery pack is used with the SKM 5200 transmitter, activation of the Command switch on the battery pack routes the audio signal to a second output on the receiver. Depending on the mode selected, the Command option switch may toggle between the two separate audio channels or add the Command Channel in parallel to the primary audio channel.
The Command Channel output from the receiver may be patched to allow this second audio signal to be routed to a broadcast production producer, for example, allowing the talent to directly address the control room off-air on a private channel. Alternatively, in the parallel mode, this second audio path might be routed to a monitor mixing console, making it unnecessary to use a splitter box in smaller live production setups. If the Command Channel output is not assigned, the switch may operate as a "cough function" or signal mute.
