Page 53 Level meter, just begins to enter the red clipping zone, then reduce the gain slightly until peaks no longer climb into the red zone. See page For information on setting up an expansion bus network, see page Page Processing Processing Processing A—H There are eight processing blocks in the XAP , each with filters, compressors, and delay to provide pinpoint audio configurations.
Page 56 When configured properly, this results in a smooth audio response throughout the frequency range, with no bass, midrange, or treble dropouts. A given compressor group must be configured for a single XAP unit; a group cannot use compressors from multiple XAP units. Threshold Threshold determines the RMS level at which the compressor begins to operate. Page 58 System Configuration The frequency response and phase vs.
Each filter can be disabled without affecting the filter settings. All filters can also be disabled using a single command. By default, they are not enabled and the filter types are not defined.
Note that as you create filters across several processing channels, you can observe their crossover points and general shape of the frequency response. In this case, several Linkwitz-Riley filters are being created across three processing channels to establish a balanced frequency response from low-frequency, midrange, and high-frequency transducers.
Page 60 Other types of delay to consider when establishing delay parameters are delays which occur naturally as a result of processing operations within the XAP Propagation delay is an example. This delay is caused by operations such as the conversion of the signal between analog and digital formats.
Page Chapter 4: Advanced Configuration You can change every unit parameter or a select few depending on your room needs. XAP presets are unique in the sense that they operate independently of other presets in the unit. Page 62 Figure 4. All Input, Output, and Processing windows can be accessed by clicking on their respective buttons. Use the Preset Description box for entering information about the preset.

It uses an internal macro language and 32 userdefinable presets to quickly adapt to a variety of teleconferencing and sound reinforcement applications such as distance learning, teletraining, telemedicine, courtrooms, conference rooms, boardrooms, hotels, and houses of worship.
In its most simple form, the XAP is a mic mixing matrix. As such, all mic mixing parameters can be customized and any input or combination of inputs can be routed to any output or combination of outputs, with attenuation adjustments at each cross point.
This allows great flexibility in accommodating a variety of applications and requirements. The XAP features numerous functions which greatly enhance its performance and flexibility. Thus, the input for a mic located in a highly reverberant part of a conference room is gated, mixed, and processed to compensate for the changes in that area and reduce echo and noise. This improves audio quality and decreases the possibility of feedback.
The XAP facilitates local and remote PC setup and diagnostics, logic outputs, and automatic gated mic operation. Mic inputs can be individually customized to gate on and off as you want, while automatic gain control keeps the overall sound level consistent. Eight of the 12 channels can be configured as an automatic microphone mixer. Adjustments in routing, level, and other functions can be made through presets activated through a closure on the rear panel, an RS serial interface, or a control panel on the expansion bus data channel.
The XAP features eight audio processing blocks, each with 15 filters. Each filter can be configured as a parametric equalizer, high pass, low pass, CD horn, high shelving, low shelving, all pass, or crossover.
This gives you real-time flexibility to meet a variety of reinforcement requirements. Network-based interconnectivity allows up to eight XAP s and XAP s to be connected and controlled as a single unit, allowing microphone coverage in applications requiring up to 64 mics. However, it can be easily interfaced to an external controller via either of the two RS ports. The unit can also interface with a PC through the RS port. The XAP now supports echo cancellation summing. Four user-definable virtual references are provided which can use multiple signals as the echo cancellation reference point without sacrificing an analog output.
This added flexibility further enhances echo cancellation performance. Our industry-leading noise cancellation keeps background noise to a minimum while retaining top-level voice quality, echo cancellation performance, and full-duplex capability. Now gain and mute adjustments can be made from the front panel.
Using these controls allows you to make quick volume and mute changes without connecting through G-Ware. The new Safety Mute button on the main G-Ware toolbar allows you to mute all outputs with one simple click if feedback or audio problems occur during the configuration process. You can now password protect your presets and macros to prevent unauthorized changes. This new button on the Matrix Screen makes it easy to clear all cross point cells in the matrix.
Simply click the button and confirm the action. The new RAMP serial command see page gives you greater control over gain adjustments. You can specify the rate at which the gain increases and decreases as well as the target level.

This assignable, peak-level LED bar meter is used to display the audio level of an input, output, or processing channel of the XAP LED 1—8. These LEDs indicate Inputs 1—8 gate status. The module uses an IEC-type connector. No switching is required. These Phoenix block connectors are for connection of eight mic-level or line-level selectable inputs.
These inputs can be mixed in any gated or non-gated combination and routed to any of the 12 outputs. Default input level is dBu. For more information about input adjustments, see page For electrical specifications, see Appendix A: Specifications. 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 92 for maximum cable run distances when using ClearOne Control Panels.
The control devices have access to the command set for the XAP and can be used for common functions such as volume control, muting, preset change, 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. The 32 presets can also be activated via these connectors. For pinout and default information, see Appendix B. These three-pin Phoenix connectors are for connection of twelve line-level balanced outputs with three-pin Phoenix connectors.
These outputs are typically used for connection to VCRs, tape recorders, amplifiers, codecs, phone hybrids, and other audio devices. These outputs may be configured to contain any combination of gated and non-gated inputs. The nominal output level is 0dBm. These Phoenix connectors are for connection of up to four line-level inputs. They can be routed to any output or multiple outputs.
Nominal level is 0dBu. The E-bus consists of two buses: one for control, the other for passing audio and mic information see Control bus, page 7. Using Cat 5 twisted-pair cable, you can separate adjoining units up to 80 feet 24 meters. See the diagram on page For serial protocol, see Appendix B: Connector Pinouts. 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. The XAP units are designed for installation in a standard inch equipment rack. You can also purchase side panels for desktop placement. See Appendix D for a list of accessories. The XAP is designed for easy installation and setup. All connections are made through rear-panel connectors. This chapter provides instructions on making hardware connections, creating an expansion bus E-bus network, assigning device ID numbers, selecting the mixer mode, and using the front panel LCD menu.
The diagram below illustrates the typical connections that are made for a single-unit. XAP system. The default routing settings in the G-Ware Matrix Screen allow the. 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. Make connections between units in daisy-chain fashion using the short RJ jumper. If your units are further apart, use category five twisted-pair cable.

Expansion Bus Out connector of the first unit in the network and. Expansion Bus In connector of the second unit.
Continue connecting units in the same fashion. Plug the expansion bus terminator in the Expansion Bus Out connector on the final unit to complete the network connections.
If the E-bus network is not connected properly, the front panel LEDs will flash on the units that are physically connected to the network. To correct the problem, check for broken connections and reconnect the expansion bus cables.
To correct the problem, change the device ID on one of the conflicting units. Once your expansion bus connections are made and if you have more than one XAP at a site , you need to set up a unique expansion bus device ID number—a. Press the front-panel Enter button, then scroll through the menu until the.
Press Enter , then scroll through the menu until Device ID is visible. Press Enter , then scroll through the eight 0—7 options. When the desired device ID is visible, press Enter to select it. Repeat this process for each XAP on the expansion bus network. There are two mixer mode settings: slave default and master.
A master unit is not required in a networked system and in most installations, all units will be slaves. Master units ignore audio from upstream units. This prevents audio from being received from units above the master unit in the network. In Figure 2. It prevents the audio from the first and second units from being passed down the network chain. Likewise the second master unit in the network will not pass on the audio from the unit before it.
The third unit provides system-wide control through a connection to its RS port. Press the front panel Enter button and scroll through the menu until System.
If an error is displayed, contact technical support. The menu tree features five main menus, each with submenus.
