Glossary - A SYSTEMS DMP808 Manual Del Usuario

GETTING STARTED
For easy control of the DMP808, you will need to connect the device to a network-enabled Windows computer. By
installing the Asystems software on a computer will allow for remote control of this unit. Enter the DMP808's IP address
into the PC software to locate the DMP808 on either the local area network.
Connect all necessary input and output devices. Input can be achieved through correctly wired euroblock connectors.
Wiring for balanced euroblock connectors should be as follows:
Pin 1: Shield/Ground
Pin 2: Cold (–)
Pin 3: Hot (+)
Whereas unbalanced connectors can be wired as so:
Pin 1: Shield/Ground
Pin 2: Link to Pin 1
Pin 3: Hot (+)

GLOSSARY

The following are a few words that may serve you
well while reading this manual. These aren't in depth
explanations, but should hopefully give you the basics
and a place to start.
Balanced Connections – balanced connections offer
three conductors, carrying a ground, an in-phase signal,
and an out-of-phase signal. Once the two signals are sent
from one device to another, the out-of-phase signal has
its phase inverted and the two signals are combined. Any
interference picked up along the way is removed through
to phase cancellation. This allows cables to be run over
long distances without collecting excessive noise on the
way.
Compressor – a Compressor reduces signals over a
user-defined threshold by a user-defined amount/ratio.
Dynamic Processor – is any kind of processor that
dynamically – or in real time – adjusts signal properties.
EQ – Equalizer – is a device or process that allows users
to boost or attenuate audio signals at specific frequencies.
Euroblock – These types of inputs allow for self-wiring
of connections for permanent installations. Check the
"Getting Started" section for more information on wiring.
GEQ – Graphic Equalizer – is in essence the same as
an equalizer, but this title is reserved for equalizers with
more 'bands' than the typical EQ. While a typical channel
EQ may only allow for 3 or 4 frequencies to be adjusted,
a graphic equalizer may allow for 31 different frequencies.
GUI – Graphical User Interface – this is the remote PC
software used for the DMP808.
HPF – High Pass Filter – a high pass filter will cut or
significantly reduce all audio signals below a particular
user-defined frequency, allowing – as the name suggests
– high frequency sounds to pass through.
DMP808 / DMP808D
High Shelf Filter – the high shelf filter will reduce or
increase all audio signals below a particular frequency.
The level at which the signal is boosted/attenuated is
determined by the user.
Limiter – work just as compressors do; however with an
input to output signal ratio permanently set to infinity-to-1.
LPF – Low Pass Filter – a low pass filter will cut all
audio signals above a particular user-defined frequency,
allowing low frequency sounds to pass through. This is
significantly useful when using subwoofer speakers on
particular outputs.
Low Shelf Filter – the low shelf reduces or increases
the level of audio signals below a particular frequency
selected by the user. The level at which the signal is
altered is also set by the user.
Network – a network is a series or group of computers that
are interconnected so as to share information. In the case
of the DMP808, the network allows for remote operation
of the device using our Windows-based computer.
Noise Gate – a noise gate is a dynamic process that
turns off or significantly attenuates the audio signal
passing through it when the signal level falls below a user
adjustable threshold.
Unbalanced Connections – unlike balanced connections,
unbalanced connections only have 2 conductors: one for
the signal and one for the grounding. This, unfortunately,
makes them more susceptible to noise and interference.
