Introduction
Congratulations
INTRODUCTION • 1
Congratulations on purchasing the XA TH2 telephone interface. The
XA TH2 is a single-line digital hybrid which uses digital signal
processing (DS ) to separate the transmit and receive audio,
eliminating distortion, weak signals, and feedback. It continually filters
low and high frequency noise to provide pure sound.
The XA TH2 is designed to function as a standalone telephone hybrid
or as an accessory to the XA 800 (echo cancelling, audio processing,
microphone mixing matrix), enabling you to add remote callers to your
audioconferences.
This manual explains how to install, configure, and operate the XA TH2
in a step-by-step format.

4INTRODUCTION • CONTROLS AND CONNECTIONS
Front View
The XA TH2 front-panel controls perform the following functions:
1. Transmit LED This bicolor LED indicates the audio levels being
transmitted from the room to the telephone line.
2. Receive LED This bicolor LED indicates the audio level the room is
receiving from the telephone line.
3. On LED This bicolor LED indicates the hybrid’s ON state. The LED
will illuminate green when the hybrid is in the ON state.
4. Off LED This bicolor LED indicates the hybrid’s OFF state. The LED
will illuminate red when the hybrid is in the OFF state.
5. On The ON button connects the XA TH2 to the telephone line and
automatically adapts the hybrid to the line. ressing and holding the
ON button for more than a half-second while the hybrid is active will
readapt the hybrid. When the hybrid is activated from the OFF to ON
state, the XA TH2 will send the updated status via the Expansion
Bus.
6. Off The OFF switch disconnects the hybrid from the telephone line
and mutes all audio.
Rear View
The XA TH2 back-panel connectors perform the following functions:
1. Power The AC power cord input is a NEMA type connector allowing
100–240VAC, 50/60Hz.

INTRODUCTION • CONTROLS AND CONNECTIONS
2. Telco Line This RJ-11 connector provides connection of a standard
analog telephone line to the hybrid.
3. Telco Set This RJ-11 connector allows connection to a standard
telephone set. Tip and ring from the phone line are present at this
connector when the hybrid is in its off state. Tip and ring from the
phone line are not present at this point when the hybrid is in its on
state.
4. Transmit Inp t This hoenix connection provides a non-gated
electronically balanced line level input. The nominal input level is 0
dBu. This line input is mutable. The default setting is off (not muted).
5. Receive O tp t This hoenix connection provides a balanced line
level output. The nominal output level is 0 dBu. The output adjusts
for line imbalances and maintains a constant output level. This line
output is mutable. The default setting is off (not muted).
6. Device ID This four-position DI Switch is used to assign a device ID
number to the XA TH2. See page 9 for more details.
7. Expansion B s In, O t This RJ-45 connector is used to connect
the XA TH2 to the XA 800 for control. G-Ware is capable of
accessing an controlling an Expansion Bus local area network (LAN)
of up to eight XA 800/ SR1212 units and 16 XA TH2 units, where
the total number of microphone inputs does not exceed 64. The
Expansion Bus supports a distance of up to 80 feet between each
connected XA 800 or SR1212.
8. RS-232 This female DB9 serial port is for interconnection between
the XA TH2 and a C, modem, or other custom remote controller.
For serial protocol, see 29.
9. Remote This DB25 connector provides control and status of the
XA TH2 and unbalanced audio. See Appendix B for pinouts.

6INTRODUCTION • BEFORE YOU INSTALL
Power Requirements
The XA TH2 automatically accommodates voltage requirements of
100–240VAC, 50/60Hz, 15W.
Telephone Line Requirements
The XA TH2 model operates on a standard analog telephone line and
connects to the telephone system with a standard RJ-11C modular jack.
If you do not have an RJ-11C jack where you want to install your
XA TH2, call your telephone company for installation.
The XA TH2 can be configured to meet compliance requirements of
different countries via the G-Ware software. See page 12.
Equipment Placement
The XA TH2 models are designed for installation in a standard 19-inch
equipment rack. You can also purchase side panels for desktop
placement.
Network Requirements
The Expansion Bus (RS-485 LAN) lets you connect up to eight XA 800s
and 16 XA TH2 units, where the total number of microphone inputs
does not exceed 64. The maximum distance between interconnected
XA 800 or SR1212 units is 80 feet (24 meters). Gentner recommends
that category five twisted-pair (10BaseT LAN) cable be used.
Environmental Requirements
The XA TH2 can be safely operated in a room with varying
temperatures between 32 °F (0 °C) and 110 °F (43 °C).

Warning: The co ntry code
m st be set correctly in
G-Ware to ens re that the
nit operates properly when con-
nected to the telco network and
complies with the co ntry’s telco
req irements. Changing this code
to a co ntry other than the intended
co ntry of operation might ca se
the XAP TH2 to be
non-compliant.
