Panasonic Ramsa Audio Mixer Wr Da7 Users Guide

							Ground loop.A type of interference in audio equipment that is grounded in
more then one location, often through cables or connections, that can be
the source of hum interference due to small currents that exists between
the two pieces of equipment. Ground loop eliminator devices can prevent
this type hum. All equipment should be grounded for safe operation.
Hertz (Hz).The unit of measure of frequency. 1 hertz equals one cycle per
second. 1KHz equals 1000 cycles per second. (K in the metric system is
short for Kilo or 1000.)
Highpass filter.See filter.
I/O. An abbreviation for Input/Output.
initialize.To reset or bring to to some predetermined condition.
K.The abbreviation of kilo in the metric system meanining 1000. See Hertz.
LED Light Emitting Diode.The DA7uses various color LED’s as visual
indicators in the buttons and the signal level meters for ease of use, long
life and reliability.
level.A general term used to describe the audio signals strength, voltage,
power or volume. 
line level signal.The level of signal used by most audio equipment. Line
level is -20db to +20db. In audio, it is known as a high-level signal.
loop.A sound that is played repeatedly. On the DA7, a software command
that instructs a process to repeat.
Lowpass filter.See filter.
Low level signal.A signal that is less then -20dB is considered a low level
signal. The output of microphones are generally low level. Generally, low
level signals are more suceptable to hum and noise.
master.A device that controls all other devices. A master gain control
controls the overall level of all the other contols under it. 
metering.The DA7metering is precise and easy to read. LED signal
indicators for inputs, outputs, bus and special effects monitoring.
MIDI. Musical Instrument Digital Interface.The musical instrument
standard that allows MIDI capable devices to communicate with each
other. The DA7can communicate with and control other MIDI devices.Glossary

Glossary-7 MIDI Timecode.An addition to the MIDI Standard to allow the
synchronization of audio equipment, such as the DA7, to MIDI equipped
devices.
Mix.The combination of various audio signals. The DA7provides an almost
limitless number of ways to combine audio signals. Complex settings can
be saved as “scenes” and recalled later.
mixing bus.An audio mixer where signals from different microphones
and/or preamps are connected and where mixing is actually done. Also
see bus and data bus.
Mix scene.The various settings of the mixer for different requirements
during a production. The DA7allows the saving and recalling of these
settings in memory.
modulation.A method of varying the frequency or volume of an audio
signal by applying a low frequency signal. Modulation can also be applied
to controls, such as Pan, to create stereo or surround sound effects. 
Mono or monophonic.A single source or channel of sound.
MTC.See MIDI Time Code. 
Noise Gate.see Gate.
non-drop frame timecode.The method of timecode computation where
there are 30 numerical frames per second of video. “There are 30 frames
of video per second,” you say. Wrong. There are only 29.97 frames of
video per second. In a mathematical hour there would be 108,000 frames
(30 frames per second x 60 seconds x 60 minutes). So, a mathematical
hour of video is 108 frames longer than an hour of reality video. See also
drop frame timecode and timecode.
ohm.A unit of electrical resistance for direct curent or impedance for
alternating current. 
output.Signal connections that can be sent or connected to another device.
oscillator.A device that produces a continuous electrical wave or tone.
pan/panning.A method of positioning the sound in a stereo signal from any
point between left and right. The DA7allows pan control positioning for
each input signal. 
						

							PPM/Peak Program MeterA peak oriented type of volt meter system
designed to detect signal overloads easily. A PPM responds to input signals
very quickly, several times faster than a Volt Unit meter.
peaking.A broad band equalizer process used to increase or decrease a wide
band of frequencies. The DA7equalizer has 4 Q controls per input fader
to adjust the frequencies affected from broad to narrow.
Phase.Signal connections. In-phase is a properly wired connections; signals
can be mixed (added) to other signals. Out-of-phase is a connection that
is reversed and causes cancelation of the signal to occur when mixed with
other signals.
Phantom power.A method of sending power to certain microphones over
standard balanced lines.
Phone Jack.A 1/4” connector used in audio. The DA7uses two types. The
Tip Sleeve (TS) for single signal connections and the Tip Ring Sleeve
(TRS) for dual signal connections. The Tip Ring Sleeve connectors are
normally used for stereo pairs, or balanced signals where there is a plus,
minus, and ground.
Phono Jack.A connector used on consumer and semi-professional audio
and video equipment originally known as the RCA jack. Also used for
digital signals (S/PDIF).
Pink Noise.A specific type of random noise with an equal amount of energy
per octave. White Noise is random noise with an equal amount of energy
per frequncy band.
Post Fader.A point in the signal path after a fader. The DA7allows for both
pre and post fader insertion. See Pre Fader.
Pre Fader.A point in the signal path before the fader. The DA7allows for
both pre and post fader insertion. See Post Fader.
Program Change.MIDI command sent to MIDI devices to change the patch
or settings.
Punch In/Out.The DA7’s automation controls allow Punch In/Out
recording.
Q.The “quality” of a filter. A low Q affects a broad band of frequencies, while
a high Q affects a narrow band of frequencies. On the DA7, Q is one of
the parameters that can be controlled with the 4 band parametricGlossary

Glossary-9 equalizer. See equalizer.
Routing.The designation of inputs, faders, buses, outputs and processes’ of
the signal. See Signal Path.
RS-422.A protocol for communication that specifies which pins in a 9-pin
cable connector are supposed to do what.
Scene Memory.The part of the DA7’s memory used to store scene settings.
Serial port or interface.See RS-422.
Shelving.An Equalization process usually used to cut or boost either high or
low frequencies.The name comes from the response curve, which looks
like a shelf.
Signal.An electrical representation of sound in audio equipment.
Signal Path or Route.The course a signal travels through audio equipment.
Signal to Noise S/N.A ratio of the threahshold level of noise to the normal
signal level. Digital systems gennerally have a higher Signal to Noise ratio.
Snapshot.See Mix scene.
save.The action necessary to save a copy of your current file on the Hard
Disk for storage. Until you save, any work you do is liable to disappear
without notice.
serial port.Data is transmitted through a serial port one bit at a time.
Transmission can be in both directions, but not simultaneously.
SMPTE.Society of Motion Picture and Television Engineers. SMPTE also
refers to the timecode recorded on audio or videotape for
synchronization purposes.
solo.Monitoring a single channel.
Surround sound.A multichannel audio format.
sync, synchronization.The coordination of a soundtrack with its
corresponding picture. 
System exclusive.A midi data format specification used to send information
between digital devices.  
						

							Talk Back.A DA7feature that allows the person operating the mixer to talk
to the studio from the control room.
TDIF/Teac Digital Interface Format.An 8-channel digital audio interface for
use with DA-88 type digital multitrack recorders (DTRS).
timecode.An eight-digit number that identifies a specific frame in a tape. It
is also an electronic timing signal, based on the 24-hour clock, that is
recorded along the length of the tape and provides markers for locating
specific program material. There are two types of timecode, non-drop
frame and drop frame. Non-drop frame timecode is based on 30 fames of
video per second. Drop frame timecode is based on 29.97 frames of video
per second. For short amounts of time, this discrepancy is inconsequential.
For longer periods of time, however, it is important. One hour of non-
drop frame timecode will be 108 frames longer than one hour of real
time. See also non-drop frame timecode and drop frame timecode.
undo.Cancels the last operation. You cannot undo a save.
VU meter Volume Units.A special type of volt meter designed and
calibrated to follow perceived audio volume. 0 VU equals +4 dBu.
window.A rectangle frame of data on the display. It lets you “see” and work
with programs, applications, or functions. Several windows can be open
at one time.
write.To record data on a medium.
Wordclock.A reference syncronization pulse used in digital audio
equipment to eliminate timing errors. The use of a dedicated wordclock
line is more reliable. It is often used in more complex systems and
multitrack recording to ensure proper syncronization.
XLR.A three pin audio connector.
zoom.Enlarging or reducing the size of an image or a display.Glossary
