2. GENERAL DESCRIPTION
The TOA TS-D1000 Series is a conference system specially designed for easy set up, disassembly and storage.
It can be used by merely connecting a number of conference units* to the TS-D1000-MU Master control unit.
Up to 32 Conference units can be connected. This number can be increased to up to 246 units (up to
2 Chairman Units) by further connecting a maximum of 5 TS-D1000-SU Sub control units.
* Collective name of the two models: TS-D1000-CU Chairman unit and TS-D1000-DU Delegate unit
3. FEATURES
• By simply connecting the required number of Conference units to the Master control unit, the system’s fully
digital audio processing system can clearly amplify all conference participant voices.
• Up to 32 Conference units can be connected to each Master control unit (1 line: 16 units × 2 lines).
• Up to 246 Conference units can be connected in a system if the maximum of 5 Sub control units are also
used.
• Inter-equipment connections can be performed in a daisy chain conguration using Cat5e STP LAN cable.
• Either ’Standard’ or ’Long’ versions of the exible microphone arm can be selected for use with the Conference
unit.
• The Conference unit’s microphone arm is designed to be easily detachable for space-saving storage.
• A test function allows easy conrmation of the Conference unit’s connection status.
• Conference mode can be selected for more effective operation during conference proceedings.
• The number of Delegate units that can simultaneously speak can be limited using the Max. open mic No.
restriction function.
• The Mic auto-off function automatically turns off the microphone after approximately 30 seconds, even if the
user forgets to turn off the microphone after speaking.
• Since the Master control unit is provided with its own individual recording function, the contents of the
conference can be recorded to either internal memory or a commercially-available USB memory device.
External recording devices can also be connected.
• The Master control unit’s power save function automatically powers down the system if the user forgets to turn
the power off.
• Conference units can be set to mute the monitor speaker or reduce sound volume when the microphone is
switched ON to eliminate concerns about feedback (howling).* Even if feedback briey occurs, the Master
Control unit’s feedback suppressor (FBS) function provides highly effective control.
* Squeal or howling sounds caused by a feedback loop created when the microphone picks up sound output
from the speaker, which is then further amplied by an amplier.

7. USING THE RECORDING FUNCTION
The TS-D1000-MU Master control unit is equipped with a recording function, making it possible to create sound
source les by recording conference dialog and the like to a commercially available USB memory device. The
TS-D1000-MU is also equipped with internal memory for recording operations, and allows recording even when
abnormalities arise with the USB memory device.
Note
Only recording can be performed by the TS-D1000-MU. Use a PC to reproduce, delete or copy sound source
les.
7.1. Notes on Use
Important
Avoid removing the USB memory device during recording. If removed, the USB memory device might not
continue to function properly, or data could be lost.
• The USB memory device cannot be formatted by the TS-D1000-MU.
• Only USB memory devices can be inserted into the USB memory port. Inserting other USB devices could
result in operational failure.
• Move the sound source le created in the USB memory device to a PC or other device without saving it to the
USB memory device.
• When inserting or removing the USB memory device, do not apply unreasonable force to the port. Failure to
observe this instruction could lead to failure of the TS-D1000-MU or damage to the PC or other devices.
• Ensure that the USB memory device is removed when moving the TS-D1000-MU from one place to another.
Moving the TS-D1000-MU with such devices inserted could cause failure to the TS-D1000-MU or damage to
the USB memory device.
• Be sure to back up recorded internal memory sound source data to a PC or other device, as data could be
lost due to the TS-D1000-MU’s failure or faulty operation.
7.2. Usable USB Memory Devices
• USB memory device (ash drive) with a capacity of up to 32 GB.
• Compatible with USB 2.0 devices.
• When using a USB memory device with the TS-D1000-MU for the rst time, format it with a PC before using.
Formatting conditions are as follows:
File system: FAT32
Allocation unit size: At least 4KB
• Insert the USB memory device into the PC and perform error checking before use.
• Ensure that the USB memory device is ONLY used with the TS-D1000-MU, and avoid using it for other
purposes.
• USB memory devices having other specialized functions, such as security functions, cannot be used with the
TS-D1000-MU
• There may be cases in which a USB memory device cannot be used with the TS-D1000-MU, depending on
the drive’s attributes or recording conditions.

7.3. Sound Source File Specifications and Filenames
Notes
• All sound inputs are mixed and recorded.
• Noise may be generated, depending on the contents or volume settings of the input sound source. If annoying,
adjust the sound volume of the conference unit or external sound source.
Shown below are specications and lename format for recorded sound source les:
• Specications
Recording format: MP3 (monaural)
Sampling frequency: 32 kHz
Bit rate: 128 kbps
Maximum le size: 54.9 MB (recording time: 1 hour)
Tips
• Since the sound source le is automatically divided each time one hour elapses, the
above is the maximum size.
• The size of the internal memory is 1 GB, allowing recordings to be made for a total of
approximately 18 hours.
• Filename format
A lename indicating the Year, Month, Date, Hour, Minute and Second of the time that the recording was
started is automatically assigned to each le as follows:
Sound source lename: YYYYMMDD_HHMMSS.mp3
Example
In the case of a recording started at precisely 10 o’clock AM on January 1, 2020,
the lename “20200101_100000.mp3” is assigned when the recording is stopped.
When a recording is continuously made for longer than one hour, the sound source le will automatically be
divided whenever one hour passes, and the resulting le saved under a newly assigned lename.
[Time Setting and Confirmation]
The recording start time included in the sound source lename corresponds to the Master control unit’s internal
clock. The internal clock can be set via network using a PC browser.
For details, please refer to the separate Instruction Manual (Browser Settings), which can be downloaded from
the TOA DATA Library (https://www.toa-products.com/international/).
