Description
Audio-Technica’s ATDM-0604 Digital SmartMixer® is a microprocessor-controlled,
programmable, automatic mixer designed to improve audio quality in meeting, conference,
or soft codec applications. The SmartMixer technology allows channels to be mixed
automatically in gate or gain sharing mode, ensuring consistent, high-quality audio output
from all inputs in a setup, without the introduction of feedback, excessive ambient noise,
or comb filtering.
For use with low-impedance dynamic and condenser microphones (including wireless
microphone systems), as well as with line-level sources, the ATDM-0604 automatically
mixes in gate or gain sharing mode for the best possible audio quality. In gate mode,
microphones or line-level inputs not currently supplying an audio signal are automatically
turned down. In gain sharing mode, the total gain within the system is kept at a constant
level by automatically adjusting the gain levels of each input currently supplying a signal.
If automatic functions are not desired, the ATDM-0604 SmartMixer can function in manual
mode, bypassing the mixer’s automatic switching and attenuation functions, causing the
unit to behave like a conventional mixer.
Each of the ATDM-0604’s six balanced inputs provides switchable 48-volt phantom
power, low-cut filter, phase inversion and 4-band EQ. Input gain can be adjusted for each
mic input; attenuation can be adjusted for line-level inputs. A selectable acoustic echo
canceler (AEC) applies to all balanced inputs. An unbalanced stereo input is also provided.
The mixer includes two balanced mono outputs and one unbalanced stereo output. Output
routing bus controls allow each input to be routed to one or both of the mono outputs or to
the stereo output. Each output channel is equipped with adjustable output level, 12-band
fully parametric EQ with notch filtering, compressor, limiter, and 8-band feedback suppressor.
Monitoring and control tools are accessible on the mixer’s front panel or on a PC, Mac, iOS or
Android device via the mixer’s Web Remote interface. Six different setting configurations can
be saved as presets for quick transitioning from one meeting setup to another.
Controls and LED indicators on the mixer’s front panel allow users to easily adjust settings.
The mixer also includes Web Remote functionality, which lets users log in and make
adjustments from a Windows-based PC, Mac, iOS or Android device (no app or other
software installation required). Logging in as an Operator allows user to make basic level
adjusts and recall presets; logging in as an Administrator gives the user full access to
system controls.
The mixer shall be equipped with four balanced mic inputs, two balanced Mic/Line inputs,
and one unbalanced stereo input. Each balanced input shall provide switchable 48-volt
phantom power, low-cut filter, phase inversion and 4-band EQ. Independent input trim (for
gain setting) and channel level controls shall be provided for each balanced input, allowing
the automatic mixer to accept a wide variety of microphone- and line-level signals. The
mixer shall also be equipped with one unbalanced stereo output and two balanced mono
outputs. Each output channel shall be equipped with adjustable output level, 12-band fully
parametric EQ with notch filtering, compressor, limiter, and 8-band feedback suppressor.
Input and output connections shall be via Euroblock connectors. Mating connectors shall
be included with the mixer. Each input shall be configurable for bus assignment to any of
the outputs.
The mixer shall be designed to allow certain inputs to have priority over other inputs
when the SmartMixer function is turned on and gate mode is selected. It shall be possible
to independently configure the priority setting for each input channel. Any number of
channels can be given priority over other channels for maximum operational flexibility.
The mixer shall allow for last microphone on operation. In this mode, the last active
microphone shall stay active (on) so that ambient sound is never muted. The time that the
mixer keeps a channel’s gate open shall be configurable from 0.5 to 10 seconds.
The SmartMixer functionality shall also be capable of operating in a gain sharing mode
that keeps the total gain within the system at a constant level by automatically adjusting
the gain levels of each input currently supplying a signal. Each channel can be weighted to
more evenly distribute the overall gain.
The mixer shall offer a selectable acoustic echo canceler (AEC) to deliver clear audio with
no echo.
The mixer shall offer a manual mode, which bypasses the mixer’s automatic switching and
attenuation functions. Front panel LED indicators shall be provided to aid in the adjustment
of system settings.
The mixer shall be equipped with a 2-channel USB audio interface for soft codec
integration or playback from a computer. The mixer shall also provide a Web Remote
interface to allow for monitoring and control on a PC, Mac, iOS or Android device.
For large multi-mic installations, up to 6 automatic mixers (a total of 36 channels) may be
connected via RJ-45 A/B link ports, using Cat5e (or better) cable (up to 100 meters). When
operating in this way, the output for all of the linked mixers shall appear at the master
mixer in the chain.
The mixer shall be a half-rack unit designed to mount in a standard 19" equipment rack.
Removable rack-mount adapters shall be included with the unit. (When mounting two
mixers side by side, a joining plate, available separately, shall be required.) The mixer shall
also mount to the underside of a table or other flat surface with the aid of a table mount
kit, available separately. The mixer shall incorporate an internal power supply designed to
operate on 120 or 240 V AC.
The Audio-Technica ATDM-0604 is specified.
