SX-2000SM SYSTEM MANAGER
The SX-2000SM System Manager is capable of performing audio signal routing and priority
control for the entire SX-2000 system. It comes with 8 control inputs, 8 control outputs, failure
status output, failure status input, and other functions that include keys, access indicators, mode
indicators and failure indicators, enabling a wide range of control and status monitoring.
Each function can be set using the SX-2000 Setting Software, and the settings data saved to a
Compact Flash (CF) card. By inserting the programmed CF card into the SX-2000SM, each
control can be performed for the entire system. It is also possible to record the entire system's
operation log and store its contents on the CF card as an operation log.
The SX-2000SM is a 1U-size* unit that can be mounted in an EIA equipment rack. It has two
power supply inputs, one of which can be connected to a backup power source to protect against
power failures.
*1U size = 44.5 mm (standard size)

3. OUTPUTTING LOG DATA (Operating DIP Switches 1 and 2)
By writing the SX-2000 system's operation log to a CF card in the ".s2l" file format and displaying this data on
a PC installed with the SX-2000 Setting Software, the data can be output as an Excel CSV file. Log data
saved to a CF card is automatically assigned the file name "SX2000_x.s2l," in which the "x" represents a
number from 0 to 9 indicating the order in which the logs have been saved. If more than ten files are saved,
the oldest files (those with lower numbers) are overwritten. The newness or oldness of a file may be
ascertained by checking its date. Shown below is the procedure for writing the SX-2000SM's log data to the
CF card.
Notes
• When storing log data on a CF card, confirm in advance that it has at least 15 megabytes of free space.
• Do not operate the DIP switch while the CF card access indicator inside the protective cover is flashing.
• Reactivating the SX-2000SM erases the log data temporarily stored in SX-2000SM memory.

SX-2000AI AUDIO INPUT UNIT
The SX-2000AI is an audio input unit for use with the SX-2000 system. It features modular
construction that allows it to handle from 2 to 8 inputs per unit. It can be mounted in an EIA
equipment rack (2U size*), and multiple units can be installed in different locations with no need
to centralize in one location.
Audio signals are transmitted digitally to the audio output unit, but an analog audio output
function (1 channel) enables simultaneous all-zone calls for use in emergency situations.
The SX-2000AI is equipped with 2 power inputs, allowing the connection of a backup power
supply for use during power failures. Level meters provided for each input channel allow
monitoring of audio input levels. Input volumes can be adjusted using the input volume controls
on the front panel, however the maximum volume when the volume control knob is rotated fully
clockwise is a default value defined by the SX-2000 Setting Software.
Also, any input channel can be monitored using the internal speaker. The key lock function,
designed to prevent accidental mistaken operation, can disable input volume control and monitor
volume control settings.
* 1U size = 44.5 mm (standard size)

A "bus" is a path through which audio signals pass. The SX-2000 system has 16 lines.
The bus selection detail display shows which bus is used to send a broadcast in progress and which output of
the SX-2000AO it is sent to. If there are two or more output destinations, only the smallest output channel
number is shown first, and this can be switched over to other output destinations by pressing the OK key.
Pressing the plus key increases the input channel number by one and displays the broadcast status for that
channel.
Pressing the minus key decreases the input channel number by one and displays the broadcast status for
that channel.
Regarding the type of broadcast, "B" is displayed for BGM broadcasts, and "P" is displayed for general-
purpose broadcasts. For input channels not making broadcasts, the indication "– – –" is displayed for bus No.,
for the SX-2000AO's device No., for the SX-2000AO's output channel, and for the type of broadcast.
