Introduction
Congratulations
INTRODUCTION • 1
Congratulations on purchasing the Audio erfect™ 10 (A 10) telephone
interface. The A 10 uses the latest digital technology to maintain the
highest possible quality audio. The A 10 is designed as an accessory to
the Audio erfect 800 (echo cancelling, audio processing, microphone
mixing matrix) to add telephone lines into audioconferences.
The A 10 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.
This manual explains how to install, set up and operate the A 10 in a
step-by-step format. It also supplies instructions on how to resolve
technical problems, should any arise.

4INTRODUCTION • CONTROLS AND CONNECTIONS
Front View
The A 10 front-panel controls (see Figure 2, above) 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 (momentary), connects the hybrid to the
telephone line (dependent upon DI switch settings), 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.
6. Off The OFF switch (momentary), disconnects the hybrid from the
telephone line and mutes all audio.
Rear View
The A 10 back-panel connectors (see Figure 3, above) 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. G-Link n This RJ-45 connector is part of the G-Link RS-485 LAN that
provides serial control and status of the hybrid. The first Gentner
unit in the local G-Link network must terminate G-LINK IN with a G-
Link terminator. Other Gentner units in the local G-Link network
must connect the previous Gentner unit’s G-LINK OUT to the next
Gentner unit’s G-LINK IN connector.
3. G-Link Out This RJ-45 connector is part of the G-Link RS-485 LAN
that provides serial control and status of the hybrid. The last Gentner
unit in the local G-Link network must terminate G-LINK OUT with a G-
Link terminator. Other Gentner units in the local G-Link network
must connect the following Gentner unit’s G-LINK IN to the previous
Gentner unit’s G-LINK OUT connector.
4. Remote This DB25 connector provides control and status of the
A 10.
5. Transmit nput This hoenix™ connector is for connecting
transmit audio (input) with the three-terminal hoenix push-on
connector to the A 800. Note that each position has three possible
wiring positions: + (positive), - (negative) and Ú (ground).
6. Receive Output This hoenix connector is for connecting
receive audio (output) with the three-terminal hoenix push-on
connector from the A 800. Note that each position has three
possible wiring positions: + (positive), - (negative) and (ground).
7. Line This RJ-11 connector provides connection of a standard
analog telephone line to the hybrid.
8. 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.
Touch-Tone Dialing
Through the G-Link (and serial commands), the A 10’s touch-tone
(DTMF) dialing capability can be accessed. This allows outbound calls to
be initiated by the A 10 without requiring an external dialer or telephone
set. This feature continues to function after connection, enabling the
user to issue tones for voice mail/pager interaction.

6INTRODUCTION • BEFORE YOU INSTALL
Power Requirements
The A 10 automatically accommodates voltage requirements of
100–240VAC, 50/60Hz, 30W.
Telephone Line Requirements
The A 10 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 A 10,
call your telephone company for installation.
Equipment Placement
The A 10 models are designed for installation into a standard 19-inch
equipment rack.
The A 10 is designed for easy installation and setup. All necessary
interface connection are made through rear-panel connectors. This
makes for easy installation, removal and, if necessary, service.
