DIGITAL RACK MIXER M32R User Manual
4.5 Appendix E: Service Information
This appendix contains routine service information for the M32R Digital Console.
Routine Maintenance
To help keep your M32R Digital Console unit in good working order and to make
sure it gives you optimum performance, we recommend that you carry out the
following about once every month.
•
Clean the control centre, as detailed in ‘Cleaning the control centre’
(below)
•
Check controls for freedom of operation. As the controls are
‘self-cleaning’, this operation will help to prevent them from sticking
•
Check the functionality of all controls, that is, control knobs, faders,
pushbuttons, LEDs, etc.
•
Check the functionality of equipment.
Cleaning The Control Centre
Switch off the control centre and electrically isolate it from the mains
before cleaning.
Clean the control centre using a dry, lint-free cloth. Do not use harsh abrasives or
solvents. When cleaning the equipment, take great care not to damage faders,
pushbuttons etc.
Cleaning a GUI Screen
Switch off the control centre and electrically isolate it from the mains
before cleaning.
Carefully wipe the surface of the GUI screen with a soft, lint-free cloth or screen
wipe specially designed for the purpose. When cleaning the GUI screen, observe
the following precautions:
•
Avoid putting pressure on the screen
•
Don’t use harsh abrasives, for example, paper towels
•
Don’t apply liquids directly to the screen
•
Don’t use ammonia-based cleaners and solvents, such as acetone.
If you are in doubt or have any queries about cleaning the GUI screens,
contact Midas Technical Support.
Equipment Disposal
When this equipment has come to the end of it useful life, its disposal may
come under the DIRECTIVE 2012/19/EU OF THE EUROPEAN PARLIAMENT
AND OF THE COUNCIL of 27 January 2003 on waste electrical and electronic
equipment (WEEE).
Hazardous substances in WEEE contaminate water,
soil and air and ultimately put at risk our environment
and health. The directive aims to minimize the impacts
of WEEE on the environment during their lifetimes and
when they become waste.
The WEEE directive addresses the disposal of products
when they have reached the end of their life and
contributes to the reduction of wasteful consumption
of natural resources. This will help to reduce pollution,
and protect the environment and ourselves.
If this equipment carries a ‘crossed-out wheelie bin’ (shown left), please do
not dispose of WEEE as unsorted municipal waste but collect and dispose of in
accordance with local WEEE legislation. The horizontal bar underneath indicates
that the product was placed on the EU market after 13th August 2005.
For WEEE disposal see our website at midasconsoles.com for information.
4.6 Appendix F: Glossary
This glossary provides an explanation of the symbols, terms and abbreviations
used in this manual.
5.1 surround:
A surround sound system created from six channels that form
a discrete signal, which is played back over a speaker system comprising
five speakers (three front and two rear) and a subwoofer (which is the ‘.1’ or
LFE channel). See LFE.
μ:
Micro- prefix symbol that represents 10
-6
or one millionth.
A
A/D:
Abbreviation for ‘analogue to digital’. The conversion of a continuous signal
into a numeric discrete sample sequence.
AC:
Abbreviation for ‘alternating current’.
AES/EBU:
Abbreviation for ‘Audio Engineering Society/European Broadcasting
Union’. See AES3.
Acoustic feedback:
A sound loop existing between an audio input and
audio output that is amplified on each cycle. For example, a mic input signal
is amplified and passed to a loudspeaker. The output from the loudspeaker is
picked up the mic, which amplifies it again and passes it back to the loudspeaker,
and so on.
AES3:
Also known as ‘AES/EBU’, this is a serial interface for transferring digital
audio between devices.
AES50:
AES digital audio engineering standard. AES50 is a high resolution,
multi-channel audio interconnection (HRMAI). Rather than a network, it is a
high-performance, point-to-point audio interconnection, although the auxiliary
data may operate as a true network, independently of the audio. HRMAI provides
a professional multi-channel audio interconnection that uses Cat 5e data cable
and is compatible with Ethernet networks.
AFL:
Abbreviation for ‘after fader listen’. A function that allows the signal to be
monitored post-fader, that is, after it has been acted upon by the fader.
Algorithm:
In computing, a set of instructions for accomplishing a specific task.
amp (A):
Abbreviation for ‘ampere’. A unit of current.
Anti-aliasing:
When referring to digital images, a technique that avoids
poor pixelation.
Area A:
Primary input control area.
Area B:
A secondary input control area.
Assignable controls:
User-assignable controls that can be set up to operate
other functions.
Auto safe:
Prevents channel from accepting scene recall.
Auto-mute:
A function that automatically mutes the channel’s signal under
certain conditions.
Auto-mute group:
A function that automatically mutes a number of selected
channels under certain conditions.
Automation:
1. Memorization and playback of changes made to mixer settings.
2. An area on the master bay that controls these.
Aux:
Abbreviation for ‘auxiliary send’ or ‘aux send’. A designation for extra
buses, typically used for sending signal to effects, headphone amps and other
destinations. See Bus.
Aux send:
See Aux.
B
Balanced audio:
A type of audio connection that uses the three leads in a cable,
connector and jack as part of a phase-cancelling arrangement to boost the signal
and reduce noise.
Band:
In EQ, a range of frequencies.
Bandwidth:
In EQ, the width of a band, that is, the number of frequencies that
will be boosted/cut above and below a centre frequency.
