newspapers, table-clothes, curtains, etc.
Do not expose this apparatus to drips or splashes.
Do not place any objects filled with liquids, such as vases, on this apparatus.
Do not install this apparatus in a confined space such as a bookcase or
similar unit.
To install this apparatus only in the place where ventilation is good.
This apparatus should be located close enough to the AC outlet so that you
can easily grasp the power cord plug at any time.
In case of emergency, disconnect the power cord plug of this apparatus
quickly.
This apparatus with Class
construction shall be connected to the AC outlet
with a protective grounding connection.
This apparatus is not disconnected from the mains as long as it is connected
to the AC outlet, even if the unit itself has been turned off.
Important Safety Instructions
1) Read these instructions.
2) Keep these instructions.
3) Heed all warnings.
4) Follow all instructions.
5) Do not use this apparatus near water.
6) Clean only with dry cloth.
7) Do not block any ventilation openings. Install in accordance with the
manufacturers instructions.
8) Do not install near any heat sources such as radiators, heat registers,
stoves, or other apparatus (including amplifiers) that produce heat.
9) Do not defeat the safety purpose of the polarized or grounding-type
plug.
A polarized plug has two blades with one wider than the other.
A grounding type plug has two blades and a third grounding prong.
The wide blade or the third prong are provided for your safety.
If the provided plug does not fit into your outlet, consult an electrician
for replacement of the obsolete outlet.
10) Protect the power cord from being walked on or pinched particularly at
plugs, convenience receptacles, and the point where they exit from the
apparatus.
11) Only use attachments/accessories specified by the manufacturer.
12) Use only with the cart, stand, tripod, bracket, or
table specified by the manufacturer, or sold with the
apparatus.
When a cart is used, use caution when moving the cart/
apparatus combination to avoid injury from tip-over.
13) Unplug this apparatus during lightning storms or when unused for long
periods of time.
14) Refer all servicing to qualified service personnel. Servicing is required
when the apparatus has been damaged in any way, such as power-
supply cord or plug is damaged, liquid has been spilled or objects have
fallen into the apparatus, the apparatus has been exposed to rain or
moisture, does not operate normally, or has been dropped.
Caution for FCC
You are cautioned that any changes or modifications not expressly approved
in this manual could void your authority to operate this equipment.
Warning for FCC
This device complies with Part 15 of the FCC Rules. Operation is subject
to the following two conditions: (1)This device may not cause harmful
interference, and(2) this device must accept any interference received,
including interference that may cause undesired operation.
Note: This equipment has been tested and found to comply with the limits for
a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one or
more of the following measures:
-
Reorient or relocate the receiving antenna.
-
Increase the separation between the equipment and receiver.
-
Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
-
Consult the dealer or an experienced radio/TV technician for help.

Introduction
Please Note!
This manual assumes use of microphone-level inputs and line-level output
for most typical SmartMixer applications. However, all inputs may be
individually switched via the included AT-DMM828 Control Software to
achieve any combination of mic-level and line-level inputs.
Signal flow can be changed via the included AT-DMM828 Control Software.
Refer to Software Manual for more information.
About the AT-DMM828
AT-DMM828 is a microprocessor-controlled, programmable, automatic-
switching eight-channel matrix mixer. It can be used with low-impedance
either dynamic or condenser microphones (including wireless microphone
systems), as well as line-level sources.
AT-DMM828 is designed to improve audio quality in broadcast, sound-
reinforcement and recording applications. One way it achieves this is
by keeping the number of open microphones to minimum, thus reducing
background noise, feedback and other distractions, while providing instant,
completely transparent switching between channels.
Each of the eight balanced inputs provides switchable 48Volt phantom
power; attenuation is also selectable on each input to allow use with line-
level signals. The mixer's outputs are balanced and non-inverting. All audio
connections terminate in block screw connectors.
Up to 16 units of AT-DMM828 (a total of 128 channels inputs) can be daisy-
chained via CAT6 cable, which carries control bus, audio, and configuration
data between mixers.
Multiple mixers linked in this way will operate as if they are a single mixer.
Therefore, microphones activated on any mixer will cause the appropriate
switching functions to occur. The link connectors are not compatible with
LAN.
Each AT-DMM828 includes two separate external control system interfaces:
Individual channel contact closures (via DB25 connector) and PC control (via
RS232 connector or USB). The RS232 connector can also be used to connect
an external control system (e.g. Crestron
® or AMX®) using “open disclosure
communication protocol” to control the mixer.
