Figure 1. The LCD is used for numeric display of audio levels, gain readouts, and limited set-up and programming functions.
See page LED Meter. The audio level of Output 8 is displayed by default. Mic On LED. These LEDs indicate microphone gate status. The bicolor LED on the button illuminates green when the hybrid is on. The On button connects the XAP to the telephone line and automatically adapts the hybrid to the line. Pressing and holding the On button for more than a half-second while the hybrid is active will readapt the hybrid to the telephone line. The bicolor LED on the button illuminates red when the hybrid is off.
The Off button disconnects the hybrid from the telephone line. Inputs 1—4. Outputs 1—8. These Phoenix-type connection blocks are for line level outputs that may be configured for any combination of gated and non-gated inputs, as well as a mix of mic and line level inputs. Inputs 5—8. These Phoenix-type connection blocks are for line level inputs.
Expansion Bus In, Out. For serial commands, see page The control devices access the command set for the XAP and can be used for common functions such as volume control, muting, preset changes, room combining, etc. Devices can be connected to either port. For instructions on how to program the control and status pins, see the GPIO section on page The default settings allow control and status of inputs, outputs, volume, and presets.
These pins are active low. For pinout and default information, see Appendix B. This is a 10W power amp connector. Telco Line. This RJ connector provides connection of a standard analog telephone line to the hybrid.
Telco Set. This RJ connector allows connection to a standard telephone set. Tip and ring from the phone line are present at this connector when the hybrid is off.
Tip and ring from the phone line are not present at this point when the hybrid is on. This power is limited to a total of mA at 15 volts for each connector. External power can be provided to control devices when more current is required. See page for maximum cable run distances when using ClearOne Control Panels. The expansion bus E-bus allows audio routing between destinations on the E-bus network.
The E-bus contains 12 independent digital audio buses labeled O—Z which can route mic or line level inputs in any combination across the E-bus network. These four audio buses are defaulted as the mic mix buses; they can communicate the NOM count and mic mixing parameters across the network to other XAP s. All gated mics are routed to the 0-bus by default. These eight buses are defaulted as auxiliary mix buses. They are used to route auxiliary audio, such as from a CD player or VCR, to and from other units on the network.
These buses are also used as mic mix buses when NOM count is not required. These mix-minus buses are defined as microphone gating groups which support first-mic priority, maximum number of mics, etc.
Unlike the audio buses, they contain only mic status and gate parameters. See page 41 for more information about gating groups. This allows control information to pass even if the units are not using the audio link. The XAP supports the full set of commands through the control bus.
Telephone line The XAP model operates on a standard analog telephone line and connects to the telephone system with a standard RJC modular jack.
If you do not have an RJC jack where you want to install your XAP , call your telephone company for installation. The XAP can be configured to meet compliance requirements of different countries via the G-Ware software. Changing this code to a country other than the intended country of operation might cause the XAP to be noncompliant.
You can also purchase side panels for desktop placement. See Appendix D for a list of accessories. All connections are made through rear-panel connectors.
This chapter provides instructions on installing the units and making initial connections, creating an expansion bus E-bus network, assigning device ID numbers, selecting the mixer mode, and using the LCD menu. Hardware Setup The diagram below illustrates the typical connections that are made for a single-unit XAP system. Figure 2. XAP rear-panel connectors The.

Figure 2. Phoenix push-on connector To connect the unit 1. Place the unit in a standard inch rack and attach it securely. Wire the inputs and outputs to the XAP using the provided threeterminal Phoenix push-on connectors. These connectors are designed for easy wiring; simply insert the desired wire into the appropriate connector opening and tighten down the top screw. Plug in the XAP to complete the installation.
