Digital Wireless - Stereo Wireless

Zaxcom's stereo wireless system transmits two channels of audio using only one transmitter and one receiver.  Using one system costs less and draws less power; the lighter weight will keep your cameraman happy too!

Stereo wireless is now better than ever with the your choice of two diffent style stereo adaptors, the STA100 or the STA150.  You can add either of them to any TRX900 or TRX900AA and instantly have a stereo wireless.

The Zaxcom Stereo Adaptor attaches to the side of a TRX900 / TRX900AA digital wireless transmitter or ZFR100 recorder, transforming it into a 2-channel device.

The Zaxcom Stereo Adaptor adds flexibility to your wireless by allowing a standard mono channel to become a bag to camera stereo link.  It provides two balanced audio inputs, eliminating ground loop problems often encountered while using wireless transmitters in a sound bag configuration.

The dedicated timecode input can be used to synchronize the internal timecode generator of the TRX900 / ZFR100 or for auto-loading audio onto the memory card.  In auto-load mode there is always an exact match of audio recorded on the TRX900 / ZFR100 and on the video camera.

The timecode / audio output connector can be used as either an audio monitor for playback of audio / confidence monitoring or as a timecode output to jam other devices.  The function is software selectable.

The external power input allows the Stereo Adaptor and TRX900AA / ZFR100 to be operated from a 9 to 18 VDC external power source.
