INTRODUCTION
MUSICAM USA the World’s Leader in codecs gives you the new LIBERTY “POTS only” codec intended
for bi-directional, remote and unattended operation.
With the introduction of the Voyager POTS Codec, MUSICAM USA has demonstrated that stable high
bandwidth links with unfailing audio and data is the new reality for broadcasting over an analog telephone
line. The new Liberty codec incorporates the same superb DSP algorithm delivering crystal clear 15kHz
mono audio in real time at bit rates as low as 24kbps with very short 100ms coding delay and a minimal loss
of quality over a standard telephone line.
LIBERTY is the economical model of MUSICAM USA’s POTS Line. It offers the same excellent audio
quality of the Voyager at a much lower price.
Liberty provides audio-link opportunities previously impossible or simply too expensive. Broadcast
journalists and sports casters now have an easy to use, high quality, compact portable field codec. LIBERTY
can be transported as carry-on baggage allowing convenient worldwide coverage with minimal equipment.
Using the LIBERTY is as simple as plugging it into a POTS phone line and dialing the destination number.
The receiving Liberty automatically answers the call and establishes the link. For POTS connections, a built-
in modem negotiates the best possible data rate for high quality low-noise and distortion free, bi-directional
audio.
LIBERTY features include:
•High quality audio at very low bit rates (as low as 9600bps)
•Remote control features for remote operation
•Special modem for POTS codec operation
•Automatic link re-connect in the event of line dropouts
•Extensive menu system caters for most individual applications
•Fast and easy configuration via a Windows 9*/ME/2K/XP software application: Toolbox.
Liberty is basically the same as the MUSICAM USA Voyager.EXCEPT; it has the following differences:
•One balanced Microphone/Line input; standard XLR three-pin male, Input 1.
•One unbalanced input channel; Input 2 is provided on a pair of RCA connectors. This is summed to
a single audio (mono) signal.
•Liberty's Intelligent Gain Control (I.G.C) on both inputs.
•DSP Based Compressor Limiter.
•Two-peak audio LED’s are provided to indicate output has reached +16dBu.
•Three peak audio level bar-graphs are shown on the LCD display; each input separately as well as
their summed (DSP) audio stream. Their order is Input 1(top), Sum (middle) then Input 2(bottom).
•A cell phone jack (3.5mm) is provided for standard bi-directional phone quality audio.
•One CMOS relay facility is provided via the DB9 connector (pins 1&6) for remote control of
equipment.
•NOTE: The following options are NOT available on the Liberty: ISDN, Rack mounting and Data
Software.
The Liberty has the same software upgrade capabilities as the Voyager Codec. Full upgrades are possible
using the MUSICAM USA Toolbox software. We are continually updating our manuals and software…Get
the latest at www.musicamusa.com.

Installation and Usage Tips
While the MUSICAM USA LIBERTY is a very reliable telecom product, its performance will only be as
good as the POTS line that it is operating over. Take precautions to remove these possible interference
sources:
•Other telephone handsets
•Fax machines
•Computer modems
•Alarm systems
•Extension bells
•Clandestine devices
Important precaution on the LIBERTY Telco-line: ENSURE THAT CALL WAITING IS DISABLED!
It is preferable to obtain a dedicated phone line from the Telco without going through a PBX or PABX. If
this is unavoidable, check that the line works BEFORE you try to do a live program. Some of these systems
have poor line characteristics and may make the operation of the LIBERTY unstable.
WARNING: DO NOT CONNECT YOUR LIBERTY TO A DIGITAL PHONE SYSTEM AS
PERMANENT DAMAGE MAY OCCUR. If you are unfamiliar with a particular facility, check that the line
you are given is NOT a digital line. This is very important because if the unit becomes faulty due to the use
of a digital phone system, the Warranty becomes void.
On most good lines, the LIBERTY is normally able to achieve 28,800 bps (Bits Per Second) at a line quality
of approximately 70%. If you are not able to achieve this level of operation, try to connect at a lower bit
rate for 50% line quality.
CHECK:
•Length of the line from your site to the local Exchange or Central Office
•Presence of stub or party lines on your local loop
•Earth leakage problem on the line
•Equipment problem at the Exchange or Central Office
It is desirable to have a local loop (The line from your office or home to the local Central Office or
Exchange.) as short as possible. Optimum performance can be expected for lines up to about two miles in
length.
In some countries, it has been the practice to have more than one phone service attached to one line. As
more lines have been installed, the services have been separated but the unused lines have remained
connected to the local loop. Even though the old line may be unused, if it is still present across your local
loop, it may cause problems Selector with your equipment operation.
A good line should have an earth isolation of better than ten meg-ohms. If your line is located in an area
where water is a problem, check out the earth leakage
Although there are many factors at the Telco end that can cause problems, a problem that does occasionally
occur is if the clock on the interface codec to your line is not synchronized to the network. A drifting clock
will cause instability and unreliable LIBERTY performance. If you suspect that this could be the problem
then contact your local Telco.

Dialing a number
Here’s how to make a connection from one LIBERTY to another using a standard Plane Old Telephone
Service (POTS) telephone line. Connect the telephone line to the modular socket (RJ11) at the rear of the
LIBERTY. Switch on and wait for the self-check functions to complete.
The LIBERTY will dial the number to establish a connection with the remote Liberty at an initial attempt of
19,200 bps bit-rate. The modems measure the characteristics of the telephone line and negotiate the highest
possible stable data rate for best sound quality.
Dialing From An Office or Hotel Room
Most hotels and offices require dialing an additional digit(s) followed by a pause to gain access to an outside
line. After entering the access number hold the “#” key until a comma (“,”) appears after the access number
on the LCD display. Now enter the rest of the telephone number. A two second pause has now been inserted
after the access digit to allow time for the outside line to be set up for dialing. The length of this pause can
be changed in the “View Config” menu.
Handset Dialing
An external telephone handset can be used to dial a number. This may be necessary if unusual telephone
system conditions cause problems with the LIBERTY dialer. Connect a telephone to the “Handset” modular
connector on the rear panel of the LIBERTY. Using the MENU NAVIGATION KNOB scroll to [DIAL]
then click MENU NAVIGATION KNOB to select. Then follow the steps below:
* If the remote LIBERTY used a handset to answer the call, the remote LIBERTY user must press the Answer
key in order to connect with the modem.

LIBERTY modems communicate over the line to establish the best possible conditions for data
transmission. The modems Selector “train” the line to compensate for variations in frequency response
and to cancel out any echo that may be present. Under some circumstances, particularly when line
conditions are subject to change, it may be beneficial to manually request the modems to "retrain" the line
by using F2 & KEY 6. The audio is muted for about 20 seconds during this process.
F2 & KEY 7 Loopback Mode
Tests all signal processing circuitry within Liberty. (Except for the modem). Input signals can be
monitored on the “Line Out” connector and headphones.
F2 & KEY 9 Renegotiate Down
Manually request LIBERTY modems to renegotiate a lower bit rate when current line conditions no
longer support the prevailing bit rate. Indicated by audible disturbances such as "popping" noises or
distortion. The audio is muted for about 1 second during this process.
