Channel numbers
There are sixteen Channel Fader Strips on the DA7 .
Depending on the selection of the four Fader Layer
controls, each strip directly controls (1) INPUT 1-16, (2)
INPUT 17-32, (3) AUX/BUS (indicated on the bottom of the
strip), and (4) a user CUSTOM/MIDI function.
The MIC/LINE INPUT knob varies the channel input gain
volume and adjusts for either a mic or line-level input. Due to
the high quality design of this circuit, there is no pad switch
necessary; the input knob range sets the input level. This
knob only affects the analog inputs 1-16.
The
PEAK/SIGNAL LED indicates when an input signal is
present (
green ), and when the input signal level is too high
(
red ).
The LED field indicators reflect the auxiliary (AUX) routing
assignments and automation parameters. The LED color
signifies the AUTOMATION/AUX button selection; AUX
(
green ), AUTOMATION ( red ).
The SOLO LED button toggles on (
red ) or off. When on, the
channel output will be routed to the MONITOR A speakers
(overriding the MONITOR A input), and to the headphones.
The FLIP LED button flips the control of the Channel Fader
Strip from one input layer to the other. The LED color
indicates the current input selection and matches the Fader
Layer control LED button colors, INPUTS 1-16 (
green ) or
INPUTS 17-32 (
red ).
The SELECT LED button, when on (
orange ), identifies the
channel as the current channel selected. Only one Fader
Strip can be selected at a time (unless it’s in stereo or link
mode).
For more detail, see Chapter 5, Channel, Library, and
Meter Windows in the Users' Guide.
The ON LED button toggles on (
red ) and off. When on, the
channel output is active.
There are two channel numbers for each strip, indicating the
INPUT connections on the Rear Panel of the
DA7 .
The AUX/BUS label at the bottom of a Channel Fader Strip
indicates its function when the AUX/BUS Fader Layer
control is selected.
See Chapter 6, Fader Layers and Channel Strips in the
Users' Guide for additional information.
AUTOMATION/AUX LED Button
The AUTOMATION/AUX LED button toggles the display of
the Channel Fader Strips LED field indicators. The LED
color indicates the current selection.
See Chapter 14, Automation and Chapter 10, AUX in the
Users' Guide for additional information.
MASTER DISPLAY Section
Pressing the METER button will display the [METER]
window group on the LCD screen in the Display Bridge.
Pressing the METER button again will cycle the three
window selections: [METER INPUTS 1-32], [BUS/AUX],
[SLOT].
Pressing the CHANNEL button will display the [CHANNEL]
window group on the LCD screen in the Display Bridge.
The window displayed will show the current mixer strip
selected.

EQUALIZER Section
EQUALIZER Section
There are three parameter knobs and four frequency range
LED buttons in the EQUALIZER section, which are used to
change the EQ settings of the currently selected channel.
The EQ ON LED button toggles the EQUALIZER on (green)
and off. When the controls are active, adjustments can be
made to the currently selected channel.
The three knobs are labeled Q(quality), FREQ (frequency),
and GAIN (gain). The additional labeling of (left),
(surround left), and (surround subwoofer) indicate the
surround sound parameters that are controlled by the knobs
when the [SURROUND] mixing area is activated. Surround
sound capabilities are discussed in Chapter 8.
The four frequency band LED buttons can be selected one
at a time, and turn on (
orange ) to show which band is
operating. They are labeled H(high), HM (high-mid), LM
(low-mid), and L(low).
Pressing the GAIN knob displays the [EQUALIZER] window
on the LCD screen. Once the [EQUALIZER] is displayed in
the LCD window, these buttons perform other shortcut
functions.
The EQUALIZER section is detailed in Chapter 7 in the
Users' Guide.
PAN/ASSIGN/ , BUS ASSIGN
Section
PAN/ASSIGN/ , BUS ASSIGN Section
SUB SL
L
Pan, bus assignment, and surround sound parameters for
the selected channel is set within this area. The pan control
is always active for the L/R bus, so you do not need to
activate the ON button to pan across the Master L/R out.
However, if you wish to pan between odd/even buses, you
must push the ON button. Assignment to the DIRECT output
is not affected by the pan control.
The additional labeling of (center) indicates the
surround sound parameter that is controlled by the knob
when the [SURROUND] mixing area is activated.
The L/R, the DIRECT, and the BUS ASSIGN LED buttons
toggle on (
green ) and off. In addition to the eight bus
selections, labeled 1 - 8, selections for L/R (master L/R)
output and DIRECT output are available. The DIRECT
output works in conjunction with the option cards installed in
the
DA7 Rear Panel, routing signals directly to the cards.
The DIRECT output is detailed in Chapter 12, D-I/O (Digital
Input/Output) in the Users' Guide.
Pressing the PAN knob displays the [SURROUND] window
on the LCD screen.
The PAN/ASSIGN/ , BUS ASSIGN section of the
Top Panel is detailed in Chapter 8 in the Users' Guide.
DYNAMICS/DELAY Section
DYNAMICS/DELAY Section
DYNAMICS and/or DELAY processing can be added to
each of the
DA7 Channels. Pressing the PARAMETER
SELECT button cycles the current parameter selections,
which are grouped in pairs. The top knob adjusts the top
parameter selection in the pair, and the bottom knob adjusts
the bottom parameter selection in the pair. The DYNAMICS
ON LED button toggles the dynamics processing on (
green )
and off for the selected channel, and the DELAY ON LED
button toggles the delay on (

monitoring purposes, as it does not appear as an input to
the mixer. Connect a 1/4” TRS phone plug to the output
signal from a cassette deck, for example. The input signals
are sent to the 2 TR B IN LED button in the monitor section.
The level is +4dB, 10kΩBAL.
Monitor A Out
These terminals are 1/4” TRS dual phone plugs at a level of
+4dB, 600ΩBAL, and connect the output of the MONITOR
Ato an external amplifier (or powered speaker) for
monitoring in the control room (CR).
Format Select Switch
This switch is used to select the signal format of the
connected device, either AES/EBU or S/PDIF. The digital
input and output are both switched. For S/PDIF usage, an
optional adapter is required. You must make certain that the
adapter connects pin #1 and #3 together.
Clock Terminating 75 ΩON/OFF & Out / Thru
Switch
Next to the WORD CLOCK IN BNC connection, this switch
should be set to 75 ΩOFF and Thru position if the
DA7 is
being used to pass the wordclock signal to other devices in
the chain.
Set the switch to 75 ΩON and OUT for terminating the
wordclock, if the
DA7 is slaved and located at the end of the
wordclock chain. The 75 ΩON and OUT position should
also be selected when the
DA7 is being used to slave other
devices to the
DA7’s wordclock. See Chapter 12, D-I/O in
the Users' Guide for more information.
Clock Input
This is used to synchronize the DA7 to an external word
clock source. This allows the
DA7 ’s internal clock to slave to
another reference, such as a digital multi-track deck or other
device. Use a BNC connection to attach an external
wordclock source.
Clock Output
This is used to slave an external device, such as a digital
multi-track machine, to the
DA7 internal clock. It can also be
used to relay an external wordclock that is being used to
synchronize the
DA7 to an external device. Using a BNC
connector, other devices can synchronize to the
DA7
wordclock.
Serial Terminating Switch
Set the switch to ON if the DA7 is the termination point of
the RS-422/485 serial transmission path. The 110Ωswitch
turns this function OFF/ON.
Serial Port [RS-422/485]
Use this serial port to connect an IBM compatible computer
having 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 an 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 nearest dealer.
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, MIDI in the Users' Guide for details.
METER BRIDGE Connector
This is used to connect the optional Meter Bridge for the
DA7 .
See Chapter 17, Options in the Users' Guide for more
details.

Option Card Slots
There are three slots for the optional audio Input/Output
cards, plus one dedicated slot for the SMPTE/V SYNC card.
The space for the SMPTE/V SYNC card 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, Options in the Users' Guide for 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 Faders 17 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 Faders 25 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 Faders 9 through
16, and is controlled by the Fader Layer Inputs 1-16. This
connection REPLACES the analog inputs 1-16 with
whatever is connected to the option card in Slot 3.
For more information regarding optional slots, see Chapter
12, D-I/O and Chapter 17, Options in the Users' Guide.
