ZEPHYR XPORT USER’S GUIDE

DIRECT RECEIVE OUT

This XLR balanced output contains the audio received from the far end.

This output is active whenever a receive signal is present. Nominal output level is +4 dBu (20 dBu clip point). Pin 1 is ground; Pin 2 "hot"; Pin 3 "return".

When used to feed an unbalanced destination, we recommend that you use pins 2 and 3 for the signal and return respectively, and leave pin 1 unconnected. By leaving the sleeve unconnected, you will prevent ground loops.

3.2.3 The AUX INTERFACE connector.

This ¼" (TRS) connector is provided primarily for interfacing the Xport's mixer to the "headset" jack on a cellular telephone (handset). Both an input and output are available on this connector. See section 3.6 for information on using the Xport with a cellular telephone (handset). However, this connector can also adds some useful flexibility for other purposes as well.

AUX INTERFACE INPUT (ring & sleeve)

This unbalanced input uses the ring (signal) and sleeve (common) conductors of this connector and permits a signal to be injected into the Xport's monitor mix. This is an unbalanced input at +4 dBu nominal level (20 dBu clip point). This signal is injected directly into the monitor/headphone mix, and is not affected by the front panel Mix control.

A few possible uses for this input are to provide headphone cueing to talent, to feed another mixer's output to the Xport's headphone mix, etc.

AUX INTERFACE OUTPUT (tip & sleeve)

This unbalanced output uses the tip (signal) and sleeve (common) conductors of this connector, and allows tapping the mix feeding the Xport's codec. This can be used for example, to provide a local recording of the program being sent. This signal is at - 27 dBu nominal level.

3.3 The INTERFACE Connector

By default, this connector is used for transmission of contact closures. It can also be used for diagnostic purposes, in which case it acts as a DCE serial port (in this case the internal ribbon cable must be moved to an alternate position inside the unit).

For information on using the Xports contact closures see:

3.4 Setups

The Xport supports two types of Setups. Dial Setups allow easy access to frequently dialed numbers. Location Setups allow easy configuration of the unit when arriving at frequently visited locations. This is particularly handy when the (optional) ISDN interface is used.

The AUTO menu is used to enter or activate Dial Setups and Location Setups.
