specific precaution is shown by picture or text near or in the ●. The message given in the
left-hand picture instructs the user to "remove the power plug from the receptacle."
Warning
Continuing to use the system with unlikely
abnormalities such as smoke and abnormal smell
and sound may cause fire and electric shock. After
turning off the power of the system's main unit
immediately, be sure to remove the power cable
plug from the receptacle. After confirming that no
more smoke is coming out, contact our sales office
for a repair request. Do not attempt to repair the
system by yourself, as it is dangerous for the user.
Should water or foreign materials enter the
system, after turning off the power of the system's
main unit immediately, remove the power cable
plug from the receptacle, and then contact our
sales office. Continuing to use the system with
foreign materials inside may cause fire or electric
shock.
If cables are damaged such as when the power
cable is broken to disconnection and cores are
exposed, contact our sales office for a repair.
Otherwise, it may cause fire or electric shock.
Do not use the system in a place where liquid may
splash on the system's main unit directly.
Otherwise, it may cause fire or electric shock.
Use the system only within the voltage range
specified in the Instruction Manual. Otherwise, it
may cause fire or electric shock.
Fully insert the power cable plug into the power
receptacle. Otherwise, it may cause fire or electric
shock.
Do not place heavy objects on the power cable.
Also make sure that the power cable is not caught
under the system. Otherwise, the cable may be
damaged and cause fire or electric shock.
Do not place flower vases, cups, containers with
water, or small metal items on the system. If water
spills or enters the inside, fire or electric shock
may be caused
Do not damage, process, bend forcefully, twist,
pull, or heat the power cable, Otherwise, the cable
may be damaged and cause fire or electric shock.
Never disassemble, repair, or modify the main
unit. Also, never remove the cover. Otherwise, it
may cause fire or electric shock.

Disposing of this Equipment
When disposing this equipment, contact an authorized industrial waste disposal operator to
handle the disposal since this equipment needs to be disposed as an industrial waste.
About this Instruction Manual
This instruction manual is intended to be used only for customers who purchased this
product.
No part of this manual may be duplicated or replicated without prior permission from TAMURA.
The information in this instruction manual is subject to change for improvement of the product
without prior notice.
Caution
When disconnecting the power cable, do not pull
the cable. Instead, be sure to hold the power plug
to disconnect it. Otherwise, the cable may be
damaged and fire or electric shock may be
caused.
Before caring for the system, remove the power
plug from the receptacle for the sake of safety.
Otherwise, it may cause electric shock.
Before moving the system, turn off the power
switch, and be sure to remove the power plug
from the receptacle, and then remove the
connection cords of the external devices.
Otherwise, cords may be damaged and fire or
electric shock may be caused.
Do not place the power cable near heat
generating devices. This may melt the covering of
cable and may cause fire or electric shock.
When using the headphones, be careful not to
turn the volume too high. Continuously hearing a
sound so loud as to irritate your ears for a long
time may affect your hearing adversely.
Do not connect/disconnect the power plug with
wet hands. Otherwise, it may cause electric
shock.
Before turning on the power, turn the volume to
minimum. Otherwise, you will hear a loud sound
suddenly, which may cause impairments such as
a hearing loss.
Do not connect/disconnect the power plug with
the power switch on. This may cause system
malfunctions.
Do not connect/disconnect the module unit and
the card unit with the power switch on. This may
cause system malfunctions.
Do not put the module unit and the card unit in
places where it is susceptible to static electricity
(such as on a carpet), This may cause system
malfunctions.
If the panel surface becomes dirty, wipe it off
using a soft cloth immersed in a small amount of
neutral detergent. Never use gasoline, alcohol,
cleanser, or freon.
The module unit and the card unit were adjusted
when installed.
Please know that if changes are made by the
customer after delivery such as replacing parts or
adjusting the internal trimmer, maintaining of the
performance afterward cannot be guaranteed.
Since the consumable parts including faders, fans,
and operating knobs tend to lose their effectiveness
with frequency and time of use, replacement is
needed according to consumption. We recommend
carrying out a periodical maintenance. For repair or
maintenance, consult with our sales representatives
or service department shown on the end of this
manual. TAMURA owes no responsibility or liability for
any failure due to improper use or alteration.
Since any dust, water, or oil inside a fader will cause
noise or level fluctuation, take measures like storing it
in a special case or covering it while not in use.
Install NT880 on a flat surface with good
ventilation. Otherwise, the internal temperature
may rise to cause system malfunctions.
Do not use in places where corrosive gas is
generated. There is a possible cause of the
malfunction or failure.

Precautions on Installation of NT110
Install NT110 with special care to ventilation according to the following precautions:
1) Do not block ventilation holes and fans on the back and bottom.
2) When you embed NT110 in a table or desk, use a structure in consideration of air flow.
3) When you stack NT110 mounted on a rack, prevent thermal influence from equipment installed below it.

1. Overview
NT110 is an all-in-one, compact digital mixer of the NT series, which inherits the functions and
reliability of our flagship model NT880.
Despite its compact size, NT110 realizes redundancy (optional) of power input and an audio signal
processing part and is suitable for applications that require high reliability, such as OB vans, live
broadcasting, production, and television and radio studios.
2. Features
Light and Compact Design
(1) This light and compact product can be installed in OB vans, where space is limited, or can be
used for portable applications.
(2) EIAJ 19-inch rack mount size (with exterior removed)
(3) Multi-channel simultaneous operation with physical 16 ch Faders and 2 Layers x 3 Banks
configuration
(4) An all-in-one model with built-in analog and digital input/output
Original Technologies
(1) Built-in audio signal processing with a high dynamic range based on 32-bit floating point
operations. Mixing can be performed without being conscious of the internal level diagram.
(2) Redundant configuration of audio signal processing and controllers are available for the first
time in the compact class.
Operational Safety
(1) Power supply in a redundant configuration, allowing for AC and DC input
(2) Applications that require high reliability are supported with a redundant configuration of audio
signal processing and controller-mounted DSP CARDs (optional).
(3) Microphone input achieves 36 dB of head room. Sudden excessive input can be resisted.
(4) The system uses no advanced OS but is composed based on firmware, realizing high stability
and quick startup.
Usability
(1) Installation of 16 ch physical faders allows for simultaneous multi-channel operation despite its
compact size.
(2) The large touch panel displays many input/output meters for monitoring to allow for viewing of
the entire mixer.
(3) The large touch panel offers intuitive operability.
(4) The inherited operability of the NT series facilitates learning of the mixing operation.
Efficient and Flexible System
(1) Cascade connection (optional) enables addition of input channels that can be simultaneously
used.
(2) Two card slots are provided. According to the system, necessary audio input/output channels or
GPIO control units can be added.

DC INPUT
Connect this terminal to DC power supply.
NFB
No-fuse breaker for DC power security. If an excessive current flows, the square part at the center
of the NFB pops up to interrupt the current (tripped). You can restore it by pushing the part. If NFB
is tripped, failure may have occurred in the component. Contact our service department or sales
representatives.
* Recommended battery: DUO-C190 (IDX); Lasts for approx. 120 minutes
* If both AC and DC power supplies are connected, NT110 runs on the power input from AC INPUT.
However, a standby current of approx. 250 mA runs on DC INPUT. Be careful of battery
exhaustion when a battery is connected.
