Congratulations on purchasing the XA 800, a highly advanced twelve-
by-twelve digital matrix mixer with Distributed Echo Cancellation, noise
cancellation, and audio processing. It uses an internal macro language
and 32 user-definable 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 XA 800 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. This allows great flexibility in accommodating a variety of
applications and requirements.
The XA 800 features numerous functions which greatly enhance its
performance and flexibility. For example, it can gate mics on and off
when the sound within a mic’s acceptance pattern reaches a certain
level. In addition, Gentner’s proprietary Distributed Echo Cancellation
makes decisions for each mic individually, based on each mic’s specific
conditions. Also, the XA 800 functions with a network architecture
which allows up to eight XA 800s and up to 16 XA TH1s to be linked
and operate as a single system.
The XA 800 monitors each mic independently, observing ambient
levels and making decisions based on each mic’s environment. 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 XA 800 facilitates local and remote C setup and diagnostics,
logic outputs, and automatic gated mic operation. Mic inputs can be
individually customized to gate on and off as you wish, while automatic
gain control keeps the overall sound level consistent. Eight of the 12
channels can be configured as an automatic microphone mixer.
All microphone mixing parameters can be customized and any
combination of inputs can be routed to any combination of outputs,
with attenuation adjustments at each cross point. This allows flexibility
in accommodating different applications and customer requirements.
Adjustments in routing, level, and other functions can be made through
presets activated through a closure on the rear panel, an RS-232 serial
interface, or a control panel on the Expansion Bus data channel.
The XA 800 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 allows you to tailor the XA 800’s audio response to
optimize the audio quality and fidelity characteristics of a wide variety of
sound reinforcement systems.
The G IO (general purpose input/output) allows switching among any
of 32 user-stored presets. This gives you real-time flexibility to meet a
variety of audio reinforcement requirements.
Network-based interconnectivity allows up to eight XA 800s to be
connected and controlled as a single unit, allowing microphone
coverage in applications requiring up to 64 mics.
The XA 800’s Macro ro™ scripting language allows the unit to
function without the need for an external controller. However, it can be
easily interfaced to an external controller or C via one of the two RS-
485 ports or through the RS-232 port.

connecting additional XA 800 units. The first XA 800 unit in the local
Expansion Bus network must have the EX ANSION BUS IN connector
terminated with an Expansion Bus terminator. The first XA 800’s EX ANSION
BUS OUT connector is attached to the EX ANSION BUS IN connector on the
next XA 800, forming a daisy-chain network. See the diagram on page 8.
8. Expansion Bus Out This RJ-45 connector (see Figures 2 and 10) is used for
connecting additional XA 800 units. The last XA 800 in the local Expansion
Bus network must have the EX ANSION BUS OUT connector terminated with
an Expansion Bus terminator. The first XA 800’s EX ANSION BUS OUT
connector is attached to the EX ANSION BUS IN connector on the next XA
800, forming a daisy-chain network. See the diagram on page 8.
9. RS-232 This female DB9 serial port (see Figures 2 and 11) is for
interconnection between the XA 800 and a C, modem, or other custom
remote controller. For serial protocol, see Appendix B: Connector inouts.
Expansion Bus Networking
This digital mix-minus bus allows audio routing between destinations on the
Expansion Bus network. It contains 12 independent digital audio buses
labeled O-Z and four A adapt/acoustic echo cancellation reference buses.
Each audio bus can route mic or line-level inputs in any combination across
the Expansion Bus network. These buses are divided into two groups—O-R
buses and S-Z buses—based on their capabilities and default settings.
O-R Buses 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 XA 800s. All mics are routed to the 0 bus by default.
S-Z Buses 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.

Also, there are four global mixer groups (A-D). They support first-mic priority, maximum number of
mics, etc., and work across all linked XA 800s. Unlike the audio buses, they contain only mic
status and gate parameters. All gated mics are default routed to the A mixer.
Global Mixer Groups A-D These mix-minus buses are defined as microphone mixer groups which
support first-mic priority, maximum number of mics, etc. and work across all linked XA 800s.
Unlike the audio buses, they contain only mic status and gate parameters. All mics are assigned to
the A mixer group by default.
A Adapt/Acoustic Echo Cancellation Reference Buses E1-E4 Allows an input from a XA 800 to
reference an output on another linked XA 800. See A Adapt and AEC Reference on page 43 for
more information.
Network equirements
The Expansion Bus (RS-485 LAN) lets you connect up to eight XA 800s. The maximum distance
between interconnected Gentner units is 80 feet (24 meters). Gentner recommends that category
five twisted-pair (10BaseT LAN) cable be used.
Equipment Placement
The XA 800 is designed to mount in a 19" (48.26cm) equipment rack. Do not block the ventilation
holes. With a desktop kit, it can be adapted for tabletop use.
Environmental equirements
The XA 800 can be safely operated in a room with varying temperatures between 32° F (0° C)
and 110° F (43° C).

Step 1— ear Panel Connections
Review the equipment placement and environmental requirements
sections (page 7) before installing the unit. Also, refer to the Rear anel
section (page 5) to make all the equipment connections necessary for
your particular application.
Step 2—Expansion Bus Connections
Begin by placing the XA 800s in their proper locations. The Expansion
Bus In and Expansion Bus Out RJ45 connectors (see Figure 2) on the
back panels are designed for connecting multiple XA 800 units.
Expansion Bus connections between units are made in a daisy-chain
fashion using category five twisted-pair cable.
The first Gentner unit in the chain (see diagram below) must have the
Expansion Bus In connector terminated with an Expansion Bus
terminator.
If networked XAP 800s are
stacked vertica y, connect
them using the short RJ-45
jumper. When networking between
XAP 800s, Gentner Communications
recommends that category five twist-
ed-pair (10BaseT LAN) cab e be
used. The maximum cab e run
between XAP 800 units is 80 feet (24
meters).
✍
The first XA 800’s Expansion Bus Out connector is then attached to
the Expansion Bus In connector on the next XA 800 in the chain.
The last XA 800 unit’s Expansion Bus Out connector is terminated with
an Expansion Bus terminator.
The LEDs will flash if there is a device ID conflict. Each XA 800 on the
network should have a unique device ID (see Step 3 – Device ID).

INSTALLATION AND SETUP • DEVICE ID 9
If the error is in the Expansion Bus connection, the front panel LEDs will
flash on the units that are not physically connected to the network. To
correct the problem, check for broken connections and reconnect the
Expansion Buses.
Step 3—Device ID
Once your physical Expansion Bus is established (and if you have more
than one XA 800 at a site), you need to set up unique Expansion Bus
Device ID numbers for each XA 800 on the network. As shipped from
the factory, all XA 800s default as Device ID 0.
To set Device ID numbers for each XA 800 unit, press the front-panel
Enter button, then scroll through the menu until the System menu is
visible. ress Enter, then scroll through the menu until Device ID is
visible. ress 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 XA 800 on the Expansion Bus network.
Step 4—Mixer Mode
Once you establish the physical Expansion Bus network and unique
Expansion Bus Device ID numbers for each networked XA 800, set the
Mixer Mode.
There are two Mixer Mode settings: slave (default) and master. The
slave setting is used in most circumstances. Master is used to split
audio on a linked XA 800 system; global control of the system is still
maintained with the first XA 800 unit in the system. For example, if you
wanted to block audio flow between units three and five in a five-unit
linked system, you would set the Mixer Mode setting on the third unit to
master.
To choose the mixer mode, press the front panel Enter button, then
scroll through the menu until the system menu is visible. ress Enter,
then scroll through the menu until Mixer Mode is visible. ress Enter,
then scroll to the desired option. ress Enter again to select it.
Repeat this process for each XA 800 on the Expansion Bus network.

LCD Programming
The XA 800’s front panel is intuitive to operate, thanks to its simple
interface: a 2x16 character LCD, menu buttons (described previously),
and a peak-level LED bar meter. Most of the XA 800’s features are
programmed with G-Ware software. See Chapter 3: XA 800 G-Ware
Software for more information.
When power is applied to the XA 800, the LCD panel will first read
INITIALIZING. If an error is displayed, contact technical support. When
initialization is complete, “XA 800” is displayed on the top line and
“Unit 0” is displayed on the bottom line.
Menu Tree
The menu tree features three main menus, each with submenus. These
branches typically end when an adjustable parameter or viewable value
is reached. The diagram below shows the LCD menu tree.
G-Ware software is required
to comp ete system setup.
✍

TECHNICAL SUPPO T: 1.800.283.5936 (USA) OR 1.801.974.3760
INSTALLATION AND SETUP • LCD MENU TREE 11
The three main menus are: System, RS-232, and Meter. All submenu
items are arranged under these menus. Use the ENTER button to
descend into a menu and its submenus and ESC to ascend back out.
Use the ▲and ▼buttons to select between items within a specific
menu or submenu group. When the last menu item is reached, the
display scrolls back to the beginning of the list, and vice-versa. Holding
down an ▲/▼button increases the scrolling repeat rate.
To adjust a parameter, first verify that the LCD shows the parameter
flashing. If the parameter is not flashing, it cannot be adjusted until
ENTER is pressed. If the parameter is flashing, adjust the value with the
▲and ▼buttons. As the value is adjusted, the parameter is updated
immediately. To store the new value, press ENTER. To discard the
change and revert back to the old value, press ESC. If the METER
button is pressed while a parameter is being adjusted, the LCD will
switch to the Meter menu.
arameters that toggle between two values (or are a list of values) will
wrap around. Holding down an ▲/▼button longer than two seconds
will engage a faster repeat rate through menu items.
Security
There are two aspects to XA 800 security (see the System-Level LCD
arameters figure at right): locking the front panel and the passcode.
Lock anel
Locking. The front panel may be locked to prevent unauthorized
adjustments to the XA 800. To lock the front panel, use the ▲/▼
buttons to select the System menu, then press ENTER. Then scroll
through the menu items to select LOCK ANEL and press ENTER.
Select ON and press ENTER again.
Unlocking. To unlock the front panel, attempt to adjust a parameter. The
XA 800 will prompt for the passcode. Upon entering the fifth character
(if entered correctly), the front panel will unlock. The default passcode
for all boxes is ▲▲▼▼ENTER.
Set passcode
Once the XA 800 is unlocked, the passcode may be changed. Before
the XA 800 will allow passcode changes, the new passcode must be
entered, then re-entered to validate the new passcode.
The front panel passcode can also be set (and reset) within G-Ware.

System Menu
There are seven system-level parameters (see System-Level LCD
arameters figure on previous page): Select reset, Lock anel, Set
passcode, Device ID, Mixer Mode, Unit ID, and Firmware Version. The
latter two are read only; they cannot be changed.
Select reset
The SELECT RESET menu item allows for one of 32 preprogrammed
presets to be selected for XA 800 use. These preset configurations
can be easily loaded via serial commands to the RS-232 port. For
example, the XA 800 may be set up for different room microphone
configurations (i.e. reset 1 for a two-mic presentation, reset 2 for an
eight-mic conference, reset 3 for a three-mic priority panel discussion
with 20 mics for audience questions, etc.). To select a preset, scroll
through the numbered presets (1-32) until the desired preset is visible,
then press ENTER. The preset will immediately be loaded into the XA
800 memory for active use.
Device ID
The XA 800’s device ID is set from this menu. There are eight device
ID selections to choose from (0–7). Select the network position you
wish to use. Within a single site, you must designate different device ID
numbers for each XA 800 unit. See Step 3—Device ID, page 9.
Unit ID
The UNIT ID menu selection allows you to access the read-only address
set at the factory. This unique ID number identifies your particular XA
800 unit and cannot be changed.
Firmware Version
This menu selection allows you to view which firmware version is being
used. This information cannot be changed.

INSTALLATION AND SETUP • RS-232 MENU 13
S-232 Menu
There are four submenus under the RS-232 Menu (see figure at right):
Baud Rate, Flow Control, Enable Modem, and Clear assword.
Baud Rate
This parameter allows you to set the XA 800’s baud rate to 9.6kbps,
19.2kbps, 38.4kbps, or 57.6 kbps. Default is 38.4kbps. Select the baud
rate you wish to use, then press ENTER.
Flow Control (hardware)
The Flow Control options are On and Off. The XA 800 will use the RTS
and CTS pins on the port to regulate the transmission and reception of
data. When None is selected, the XA 800 ignores flow control, making
the connected device ensure that data is not lost. Software flow control
(Xon/Xoff) is not provided. Default is On.
Modem Mode
This parameter configures the RS-232 port for connection of a modem.
When On is selected, the XA 800 will send an initialization string to the
modem on power-up and require a password before data transfer is
allowed through the port. When Off is selected, the password is
disabled and the port is left in a passive mode. Default is Off.
The modem configuration must be performed as follows:
1. Forced connect speed must match that of the XA 800.
2. Echo must be turned off.
3. Response mode must be turned off (i.e., no OK messages, Ring, etc.).
4. Auto answer must be enabled.
5. Caller must select the baud rate of the local XA 800 for the mode
