Digital audio mixing - stepping into ENG and EFP
E
ffective audio quality is now more important than ever for Electronic News Gathering (ENG) and Electronic Field Production (EFP) applications
because, even with high-quality video, lackluster audio performance will result in a mediocre production.
Introducing the DMX-P01 Digital Portable Mixer, Sony’s answer to these high-quality audio requirements. Not only does the DMX-P01 offer
outstanding audio quality, it is also one of the most user-friendly mixers in the ENG and EFP markets.
With full 24-bit processing and a sampling rate of either 48kHz or 96kHz, the DMX-P01 provides sound quality comparable to high-end production
mixers. Its front panel is human engineered to allow fast, easy, and accurate setting adjustments - essential when working in the field. It also
includes other useful features, such as panel-lock and parameter-lock functions, selectable meter scales, camera-audio return-level check,
memory function, digital cascade capability, and digital outputs.
All of this functionality and versatility is packaged into one sleek, compact, and lightweight body that can be used effortlessly in field productions.
Make the DMX-P01 your first step into the world of portable digital-audio mixing in the field.
◗◗◗Digital Benefits of the DMX-P01
Excellent Sound Quality/Full Digital
Processing
In order to provide outstanding sound quality for ENG and
EFP applications, the DMX-P01 offers full digital-audio
processing. Its 24-bit A/D and D/A converters provide a
high level of linearity for analog inputs and outputs.
Internally, the unit utilizes 32-bit digital processing for
maximum throughput. In addition, the DMX-P01 has a
sampling rate that is selectable from either 48kHz or
96kHz.
High-Quality Digital Limiters/Compressors
By using digital limiters and compressors, the DMX-P01
can provide extremely high-quality sound in one small
package. Limiters are available at the input, and both
limiters and compressors are available at the output for
maximum flexibility.
Full Parameter Controls From The Front
Panel
The DMX-P01 puts all of its controls at your fingertips,
with a cleanly organized and logical layout on the unit’s
front panel. The DMX-P01 processes audio digitally, so
parameters that are used less frequently are stored
internally and accessed only when needed. Using the
front-panel controls and easy-to-read LCD allows full
control of every parameter without the need to remove
the unit from its audio-organizer case. The LCD panel is
also equipped with a backlight, so the unit can be used
in low-light conditions too.
Panel-Lock and Parameter-Lock Features
One major concern for audio engineers in the field is the
accidental bumping of controls, which can inadvertently
change the sound settings. The DMX-P01 safeguards
against this with its panel-lock feature, which can be set
to secure all of the control settings, or selected individual
control settings. With the lock engaged, physical contact
with the controls will not alter their settings. In addition,
a Parameter-Lock feature also avoids inadvertent
parameter changes.
Flexible Meter Scales
Because the DMX-P01 is a digital mixer, the meter
calibrations can be easily changed from one type to
another without the need to replace the entire meter.
LEFT PANEL
Six easy-to-change meter scale sheets are supplied:
VU, PPM1 (BBC-type), PPM2 (DIN-type), PPM3 (NORDICtype), PPM4 (IEC-type1), and dBFS. Simply insert the
desired scale sheet and select the appropriate meter type
from the setup menu. The DMX-P01 will display the
audio level according to the scale selected.
Camera-Audio Return-Level Check
The DMX-P01 enables users to visually verify that the
mixer’s audio level matches the level recorded to the
camcorder tape. This is done using the camera return-level
mode, available in the setup menu. Simply send a
reference tone signal to the camcorder and the level
difference between the mixer output and camcorder
return signal will be displayed. Then adjust the marker to
the central position, and the level adjustment is complete.
Memory Function
The DMX-P01 processes audio digitally, so users can
effortlessly store and recall parameters from the setup
menu. There are two memory functions: “Power-On
Memory Recall,” and “Scene Memory Recall.”
Power-On Memory Recall - When the DMX-P01 is powered
on, the system is capable of recalling parameters in three
different ways: with the default factory settings, with the
same settings as the last time the unit was used, or with
the parameters of one specific scene memory.
Scene Memory Recall - This feature allows users to recall
up to ten different user-defined parameter settings or the
factory default settings.
In situations where a single unit is required to serve
multiple users or multiple shooting scenarios, these
features can prove invaluable.
Digital Cascade
For applications requiring additional inputs, DMX-P01
mixers can be cascaded using a digital connection
between mixers. The benefit of cascading mixers digitally
is that sound quality is not degraded, as it would be when
cascading analog mixers.
Digital Output
The DMX-P01 is equipped with a digital output, which
can be used to send audio to digital peripheral equipment
such as DAT recorders. AES/EBU and S/PDIF coaxial
interfaces are available.
