Panasonic Ramsa Audio Mixer Wr Da7 Users Guide

							Serial Port [RS-422/485]
Use this serial port to connect an IBM compatible computer that has an RS-
422/485 port. Connect to the DA7 with a D-SUB 9-pin connector. Optional
remote control software for your computer can be used to control the DA7,
thus expanding the features and capabilities of the mixer.
Serial Port [TO PC]
Use this serial port to connect with a Macintosh computer. If the computer is
IBM compatible, you may need a conversion cable that changes a Mini-DIN 8
pin (for TO PC) to a D-sub 9 pin(for RS-232C), available at your nearest
dealer, shown in Appendix E, Cables and Connections.Optional remote
control software for your computer can be used to control the DA7, thus
expanding the features and capabilities of the mixer. 
MIDI IN
This connector is used to receive signals from peripheral MIDI devices.
MIDI OUT
This connector is used to send signals to peripheral MIDI devices. The DA7
can be used as a MIDI controller. See Chapter 11, MIDIfor details.
METER BRIDGE Connector
This is used to connect the optional Meter Bridge to the DA7.
See Chapter 17, Optionsfor more details.Chapter 2

DA7 Tour
For TO PC, use only a Macintosh Printer Cable (cross type) to
connect two DA7s each other, or between the DA7and the serial
port of a Macintosh computer. Using a straight type of modem
cable may cause malfunctions in serial communications. For more
details see Appendix E, Cables and Connections. 
						

							Option Card Slots
There are three slots for the optional audio Input/Output cards, plus one
dedicated slot for the SMPTE/V SYNCcard. The space for the SMPTE/V
SYNCcard is located directly under the MASTER OUT XLR connectors.
Audio option cards are next to the power switch. The audio option cards can
be used in any of the audio slots, but for TANDEM operation, the TANDEM
card MUST be used in Slot 3.
Video Sync Input [V SYNC]
This is used to connect a vertical synchronizing signal from a video device.
See Chapter 17, Optionsfor more about SMPTE/V SYNC.
Digital I/O Slot 1 [CH17-24/SLOT 1]
When an option card is inserted into Slot 1, the output of the connected
device appears on Channel Faders17 through 24, and is controlled by the
Fader Layer Inputs 17-32.
Digital I/O Slot 2 [CH25-32/SLOT 2]
When an option card is inserted into Slot 2, the output of the connected
device appears on Channel Faders25 through 32, and is controlled by the
Fader Layer Inputs 17-32.
Digital I/O Slot 3 [CH9-16/SLOT 3]
When an option card is inserted into Slot 3, the output of the connected
device appears on Channel Faders9 through 16, and is controlled by the
Fader Layer Inputs 1-16. This connection TOGGLES the analog inputs 9-16
with whatever is connected to the option card in Slot 3.

Quick Start
As with any mixer, the basics come first. Take it out of the box, plug it into a
standard three-prong, 120v 60Hz electrical outlet, and turn it on. Once the
novelty has passed of seeing all the colored lights and the faders going up
and down when the buttons are pressed, your real fun can begin.
There are several basic functions that, once you become familiar with, will
make the DA7 easy to use. This Quick Start Guideassumes that you have a
basic knowledge of audio technology.
Chapter 3
Quick Start
If you have already started pushing buttons, press the Fader
Layer INPUT 1-16LED button, turn off all the channels, and
lower all the faders. Then, press the CHANNEL button to display
the [CHANNEL] window. Or, if you wish to start fresh, reset the
DA7 back to the factory presets by turning the unit off. Then hold
down both the METER and CHANNEL buttons in the MASTER
DISPLAY area. While holding these buttons down, turn the DA7
back on. Your mixer will restart automatically.
The “reset to default” procedure, in the tip above, will reset all
the mixer functions and clear all the library and memory registers.
This is an irrevocable procedure. You can protect your data by
copying it to a backup using the [MIDI>BULK]procedure
described in Section 11-4.

The following five modules will give you a fundamental understanding of the
primary features of the DA7. This chapter does not cover all of the features of
a particular example, since it is meant as an introduction. If you do not
understand something, go to the chapter that is referenced for further
information. MIDI and automation functions are not included in this chapter
and will be addressed later in this Users Guide.

Quick Start
Connect an input source _
From the source to the Rear Panel of the DA7,
connect an XLR connector to INPUT 1, or to a 1/4” TRS phone plug to
INPUT 9.
Attach an output monitor _
In a production environment, attach the
amplifier input to the DA7 MONITOR A OUT and press the L/R
selection button of the MONITOR Asection. In a live mix situation,
attach the amplifier input to the DA7 MASTER OUT. 
Preset the MASTER L/R_
Raise the MASTER L/Rfader to zero. This
fader sets the master output level.
Press the MASTER L/R ONLED button _
This LED button turns the
MASTER L/Rchannel strip on (red).
Press the Fader Layer INPUT 1-16LED button _
This will assign the
Channel Fadersto inputs 1-16.
Activate SELECT_
Above each Channel Fader ON LED button is an
LED button labeled SELECT. Pressing this will turn it on (orange).
Once selected, it activates the area near the LCD display. Here,
parameters can be assigned to the channel, such as EQ, dynamics, pan,
or aux, if desired.
Press the L/RLED button in the PAN/ASSIGNsection _
This is where you
assign an output path. Pressing the L/R LED button turns it on (green).
This will assign the selected Channel Faderto the L/Routputs of the mixer.
(Pan is always active on the L/Routput of the DA7. )
Select Channel Fader 1or 9, and then press the Channel Fader ON
LED button to turn the channel on (red).Raise the Fader to zero.
Adjust the input gain _
Turn the MIC/LINE INPUTknob on the
Channel Stripto set the incoming signal type and level.1

There is a shortcut to placing any Fader to zero level. Hold down
the SELECTLED button for the Channel and simultaneously
press the ONLED button. The Fader will move to zero level.

Quick Start
While sending a signal through the channel, look below the MIC/LINE
knob, and you will find the PEAK/SIGNAL LED. This LED will light
(green) when the signal is present and below clipping.
When the signal is near clipping, it will light (red), showing that you are
either close to or at an overload condition (something you should not
do in digital recording), and you should reduce the level using the
MIC/LINEknob.
This is an important adjustment. Since this stage of gain is before the
A/D converter, it is important to get the maximum signal (without
overload) to the converter so that you will have the best possible signal
to noise ratio. Too high of a signal will cause distortion, and too low of a
signal will quite possibly introduce unwanted noise to your recording.
Adjust the levels _
With a source connected to the mixer, audio levels
can be adjusted via the MIC/LINE INPUTknob. This controls the
channel input level.
Channel Fader. This controls the channel output level to the selected
bus or direct out.
MASTER L/R Fader. This controls the MASTER L/R output level of the
DA7.
MONITOR A LEVELknob. This adjusts the control room monitor
volume without affecting the mixer output level.
With the Channel Faderand MASTER L/R Faderset at 0, while
watching the PEAK/SIGNAL LED of the Channel Strip, turn the
MIC/LINE INPUTknob to adjust the level to “peak”. Generally,
“peak” is when the PEAK/SIGNAL LED flashes (red),which
should be very rare!
The [GAIN] soft knob in the [CHANNEL] window provides
additional level control for the selected channel. Cursor to the soft
knob and rotate the JogDial to boost the audio level, when
additional gain is needed. The [GAIN] soft knob range is -24dB to
+12dB.

3-2 Module B, Onboard Signal Processing
Each of the 32 input channels, the 8 buses and the MASTER L/Routput of
the DA7has the option of inserting a 4-band Parametric Equalizer with
various filter types. There is also a Dynamics Processor on these same
channels that offers you a choice of GATE + COMPRESSOR or
EXPANDER. There is also a 0 to 300 ms Delay Processor for each of the 32
input channels. AUX 1-6 Returns have a 2 band Parametric Equalizer.

Adjust the Compressor+Gate _
The [COMP] area has software control
for [THL] (threshold), [RATIO], [ATK] (attack), [RLS] (release), [GAIN],
and [DLY] (delay). The [GATE] area gives you control over [THL], [ATK] and
[RLS].
Or,
Adjust the Expander _
This is similar in appearance to the [COMP] area,
except [GAIN] is replaced by [RANGE].
Adjust the Delay _
This area has two fields for adjustment. The first one
allows you to change the Delay for the selected channel by 1 msec step. The
other allows you to change the Delay for the selected channel by 1 sample
step. You can also enter a number in either field using the numeric keypad.
