1. About the TS-990S USB Audio Function
This guide is a document for the ARUA-10 software which connects the TS-990S and the
PC with a USB cable and makes it possible to use the speaker and microphone of the
PC instead of the speaker and microphone of the transceiver body.
When the TS-990S is connected to the computer using a USB cable, the USB audio
function can be used to play incoming audio over the computer speakers and transmit
audio from the computer microphone.
This guide explains how to set up the TS-990S to use its USB audio function and how to
use the ARUA-10 software to control input/output routes of the USB audio signals from a
computer.
Important
USB audio may be delayed due to unavoidable principles. Consequently, do not
perform operations (such as contests or pile-ups requiring quick responses) for
which delays are likely to be a problem.
Refer to Chapter 5, “Limitations", for other limitations.
To use the USB audio function, knowledge not only of transceivers but also of
computers is required. JVC KENWOOD does not offer support for purchasing
computers or for customer's computers.
JVC KENWOOD Corporation shall bear no responsibility for related damage such
as damage caused by missed communications and dialog opportunities due to
incorrect customer settings, nonconformances, or misoperations as a result of
using this document or the ARUA-10 software.

Diagram 1: Operation Using the USB Audio Function
The left side of the diagram shows the TS-990S unit while the area in the square on the
right side indicates the computer. The TS-990S and the computer are connected using a
USB cable. The microphone and speakers connected to the computer are shown on the
far right.
Audio reception is explained first. Incoming audio from the TS-990S is sent to the
computer via the USB cable and played over the speakers connected to the computer.
A signal pathway on the computer to connect the USB audio device input signals and
output from the audio device connected to the speaker is necessary.
Audio transmission is explained next. Audio input from the microphone connected to the
computer passes through the USB cable and is transmitted by the TS-990S unit.
A signal pathway on the computer between input signals from the audio device
connected to the microphone and output from the USB audio device is necessary.
The ARUA-10 software serves as a bridge for these signal paths within the computer.
The ARUA-10 software lets you select which speaker and microphone are used for
transceiver operations when there are multiple speakers and microphones connected to
the computer.

5. Limitations IMPORTANT！
5.1 USB Port Connectivity Limitations
If the PC and TS-990S are connected via a USB cable, audio transmissions can be
transmitted using the USB audio function. In principle, however, there is a delay with
USB audio signals. Additionally, sound may be delayed or lost depending on the PC
performance and load status. As such, do not perform operations for which delays are
likely to be a problem (such as contests or communications requiring quick responses).
Also, when connected with a USB cable, alert sounds from other software or audio from
music or videos may not play over the computer speakers.
Furthermore, when the DATA VOX function of the transceiver is “ON” and the
computer and transceiver are connected with a USB cable, the transceiver may
send sounds emitted by the computer. To avoid unintended transmissions when
the computer and transceiver are left connected via USB, set the DATA VOX
function to “OFF.”
Depending on the combination of OS, PC and sound functions, the USB audio function
may not operate correctly. JVC KENWOOD does not offer support for customer
computers.

6. Frequently Asked Questions
This section introduces questions that have been asked to date, and subjects verified by
JVC KENWOOD Corporation.
Question
Answer
Installation
Where can I get the USB audio
drivers?
You do not need to download the drivers.
When the computer and TS-990S are
connected via USB for the first time, the
standard driver for your operating system
is automatically installed.
There appears to be many
limitations. Is it actually
possible to operate using the
USB Audio Function?
Although it may not run exactly the same,
when you get used to it, general
communication on a practical level is
possible.
The point is to become accustomed to the
delays particular to USB audio. You may
have some initial confusion with issues
like the standby timing.
Can I use a USB or Bluetooth
headset?
You can use a USB or Bluetooth headset.
However, due to unavoidable delays using
these devices it takes time for spoken
audio to be transmitted. Also, time is
required for received audio to reach the
headphones.
We do not recommend use of these
devices when such delays can cause
problems.

15
Question
Answer
Operation
I cannot hear audio from the
transceiver over the computer
speakers.
It is possible that the USB audio output
level from the TS-990S is too low. Try
adjusting the Menu items:-.
No. 7-08: The main band USB audio

This may also depend on the
specifications of the sound device used in
your computer. Try using another sound
card or USB sound device.
The sound device driver may need to be
upgraded. Try checking for new versions
and upgrade the driver.

17
Question
Answer
Operation
Even though the transceiver is
in transmission mode, I cannot
transmit voice input from the
computer microphone.
If USB audio is not set to the audio source
line for transmission, audio input of the
USB audio is not sent.
Refer to “4.1.1 Setting Up an Audio Input
Route from the Rear Terminal” and check
the settings.
When transmitting using the TS-990S
microphone PTT or “SEND” key, USB
audio received by the TS-990S is not
transmitted. When using the ARCP-990,
the “Transmission Controls Settings” are
required.
Refer to “4.2 Setting the Transmission
Method for Audio Input to the Rear
Terminal” and check the settings.
If there is a mistake in the ARUA-10
settings, USB audio input to the TS-990S
is not transmitted.
Refer to “4.4 ARUA-10 Settings” and
check the settings.
If the computer microphone or headset is
muted, audio is not sent from the
computer.
Please check your computer’s sound
function settings.
The transceiver does not
transmit VOX when audio is
input from the computer
microphone.
In order to transmit VOX when voice data
input is received through the rear terminal,
specific menu settings are required.
Refer to “4.1.4 Data VOX Settings”and
“4.1.5 Other settings for the DATA VOX”
and check the settings.

18
Question
Answer
Operation
The end of audio
transmissions are cut off. The
system switches back to audio
reception before sending all of
an audio transmission.
When using the ARCP-990, if you quickly
switch to receive mode after using the
computer’s microphone to transmit, you
may have switched before the audio is
transmitted because of the delay in
transmitting an audio signal via USB.
If this happens, it may be possible to
avoid such delays by slightly changing the
method of operation, as described below.
・After transmission, watch the power
and ALC meters and wait until the
audio input to the transceiver finishes
before switching back to reception
mode.
・Use the DATA VOX function.
・Use a regular stereo jack instead of a
USB or Bluetooth headset.
・Set the delay time to reception
transition. (TX/RX menu > Select
Modulation Line… >Delay by TX to
RX Transition)

19
Question
Answer
Operation
The transceiver transmits, even
with no voice is input from the
microphone, when the DATA
VOX function is set to ON.
Turning the DATA VOX function
to ON causes the transceiver to
transmit, even when the
microphone is not connected.
The transceiver transmits
without my knowledge.
When the DATA VOX function is ON, for
laptop computers with internal
microphones, sounds near the computer
that are loud enough to trigger the VOX
are sent to the transceiver and are
transmitted by VOX. Sounds from other
software may also be sent to the
transceiver and transmitted by VOX.
Please try the following.
・Refer to “4.1.5 Other settings for the
DATA VOX” and adjust the VOX Gain.
・Use a headset.
・While operating the transceiver, do
not use other software.
If the above methods do not work, turn
OFF the DATA VOX function.
Also, when the computer is left connected
to the transceiver using a USB cable,
sounds from other software, such as
alerts, music and video are transmitted to
the transceiver and sent by VOX
unintentionally.
If you leave the computer and
transceiver connected using a USB
cable, turn OFF the DATA VOX function
before using your computer.
Reception quality depends on
the device.
Voice audio is affected by voice encoding
and the quality may differ from the original
voice reception quality. This is part of the
USB sound function specifications and is
unavoidable.
I can hear the beeping and
voice guidance audio from the
transceiver on the computer.
Alternatively, I want to be able to
hear them, but can't.
This can be configured in the transceiver
menu.
Please refer to “4.1.3 Mixed Beep
Settings to External Audio Outputs”.
