CHAPTER 1: Introduction
Congratulations on purchasing the Audio Perfect®telephone interface. The AP10
uses advanced digital technology to maintain the highest possible audio quality. The
AP10 is designed as an accessory to the AP800 (echo cancelling, audio processing,
microphone mixing matrix) and enables the AP800 to connect to a standard
telephone line.
The AP10 is a single-line digital hybrid which uses digital signal processing
(DSP) 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.
Easy to install and operate
DTMF dialing capability
Simultaneous two-wire/four-wire operation within an Audio Perfect
system
G-Link network interconnection with up to eight AP800s and 16 AP10s
9.6kHz sampling rate allows continual adaptation to telephone-line
conditions
Full-time telco echo cancellation with 26 millisecond tail time
Conference up to 16 callers (with 16 AP10s) within an Audio Perfect system
Digital anti-alias filter minimizes hum and Central Office switching noise
Remote On/Off control via serial commands or rear-panel connection
Digital send filter/limiter for telephone line noise reduction
Compatible with any analog telephone system
No outside RF interference will affect performance

A.
DIP switches.
Operational features can be enabled or disabled via DIP
switches behind this panel. These features include auto-answer, auto-disconnect,
momentary or latching mode, device identification, caller AGC, caller boost, and
noise burst adapt/self adapt.
B. Transmit LED. This bicolor LED indicates the audio levels being transmitted
from the room to the telephone line.
C. Receive LED. This bicolor LED indicates the audio level the room is
receiving from the telephone line.
D. On. The On button connects the AP10 to the telephone line (dependent upon
DIP switch settings) and automatically adapts the hybrid to the line. The
LED will illuminate green when the hybrid is in the On state.
E. Off. The Off button disconnects the hybrid from the telephone line and mutes
all audio. The LED indicates the hybrid’s Off state. The LED will illuminate
red when the hybrid is in the Off state.

A. Power. The AC power cord input is a NEMA-type connector allowing
100–240VAC, 50/60Hz.
B. G-Link In, Out. This RJ-45 connector is used to connect the AP10 to the
AP800 for control. AP-Ware is capable of accessing and controlling a
G-Link local area network (LAN) of up to eight AP800/AP400 units and
16 AP10 units. G-Link supports a distance of up to 20 feet between each
connected unit.
C. Remote. This DB-25 connector provides control and status of the AP10 and
unbalanced audio. See Appendix B for pinouts.
D. Transmit Input. This Phoenix connector is used to connect transmit audio
(input) from the AP800 to the AP10, which is then sent to the telephone
line.
E. Receive Output. This Phoenix connector is used to connect receive audio
(telephone participant audio) from the AP10 to the AP800.
F. Telco Line. This RJ-11 connector provides connection of a standard analog
telephone line to the hybrid.
G. 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.

Introduction ~ Before You Install
Technical Services Group ~ 1-800-283-5936 (USA) ~ 1-801-974-3760
Power requirements
The AP10 automatically accommodates voltage requirements of 100–240VAC,
50/60Hz, 15W.
Telephone line requirements
The AP10 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 AP10, call your telephone company for
installation.
Equipment placement
The AP10 models are designed for installation in a standard 19-inch equipment
rack. You can also purchase side panels for desktop placement.
Environmental requirements
The AP10 can be safely operated in a room with varying temperatures between
32°F (0°C) and 100°F (38°C).

The AP10 is designed for easy installation and set-up. All connections are made
through rear-panel connectors. This section provides instructions on installing the
units in the rack and making initial connections, creating a G-Link network, and
assigning device ID numbers.
The diagram below illustrates the typical connections that are made when
adding an AP10 to an AP800.
CHAPTER 2: Installation

Hardware Setup
Connect the unit
Refer to the rear-panel drawing in Figure 2.2 on the following page. Each connector
is numbered for easy identification.
1. Place the unit in the rack and attach it securely. AP10 models are designed
for installation in a standard 19-inch equipment rack.
2. Connect your telephone line from the wall jack to the RJ-11C Line jack [F].
3. Plug your telephone set into the RJ-11C Set jack [G].
4. If you are using a custom controller for control and hybrid status, plug it
into the DB-25 Remote connector [C].

5. Wire the AP10 to the AP800 using the provided three-terminal 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.
Transmit Input Audio connected to the Transmit Input [D] will be sent
down the telephone line.
Receive Output Audio from the telephone participant is passed to
Receive Output [E].
Creating a G-Link network
1. Place the AP units in their proper locations. The back-panel G-Link In and
G-Link Out [B] connectors are designed for setting up your G-Link network.
G-Link connections between AP units are connected in daisy-chain fashion
using category five twisted-pair cable.
2. The first ClearOne unit in the chain must have the G-Link In connector
terminated with a G-Link terminator (provided).
3. The first ClearOne unit’s G-Link Out connector is then attached to the
G-Link In connector on the next unit in the chain. At the end of the network,
the final unit must have the G-Link Out connector terminated with a G-Link
terminator as well.
A G-Link network will allow interconnection of up to 16 AP10s and eight AP800s.
If the AP units are stacked vertically, connect them using the short RJ-45 jumper
(provided). If networking over longer distances (up to 20 feet/ 6.1 meters between
units), use Cat 5 twisted-pair (10BaseT LAN) cable.
