OPERATION MANUAL

Thank you ... for purchasing the digital equalizer DEOSE. In order to take full advantage of all the
DEQSE's advanced features and capabilities we urge you to read this operation manual thoroughly before
using the DEOSE. Be sure to store the manual in a safe place when you finish.
The main operations of the DEQ5E are reliant upon on the DEOS (or an equivalent personal
computer).
When no contents regarding equalizing operations or utility settings are specified, these two items are
controlled by DEQS’s remote control operation.
Before you read the manual
@ The "DEQS(E)" in this manual refers to DEQS or DEQSE.
Ф For convenience, the software functions explained in this document (such as Mode, Menu, and Parameter) use the
same nomenclature as DEQS.
Accessories
This DEQSE package contains the following items.
€ DEQSE main unit
@ Operation manual
Outline and features of the DEQ5E
* Features of the operation panel
This unit, except for a few specific functions, has no controls or switches for operating the various parameters
inside the main unit.
* High functionality is made into compact size
Because this unit's various operations and settings are reliant upon external devices, a minimum of operational
keys, displays, and controls are provided. This results in 1U compact size.
* Two equalizer modes
wo main equalizer modes are incorporated: the 30-band +15dB variable graphic equalizer mode (GEQ mode), and
e 6-band +15dB variable parametric equalizer mode (PEQ mode).
emote control is enabled from a personal computer
This unit's parameters can be controlled on a personal computer. Do this by connecting the DEQS(E) to a personal
computer with an RS-485 interface, and using DEQS(E) control software.
* 2-channel stereo specifications
The equalizer section is capable of handling 2-channel stereo. The basic specifications of the equalizer section, with
a few exceptions, are the same as the DEQS.
Each parameter can separately or simultaneously control the left and right channels (parameter link).

* High performance A/D and D/A conversion section which contributes to high class sound quality
A 19-bit conversion process is used in the A/D conversion section, while a 20-bit conversion process is used in the
D/A conversion section. This makes a dynamic range of 110dB or more possible (analog input when EMPHASIS is
on) and contributes to higher sound quality reproduction.
Independent digital delay built in for each channel |
In addition to the equalizer function, a digital delay (used for phase compensation) is independently built into each
channel.
* Built-in hum filter
A hum filter has been incorporated into the unit to eliminate hum and harmonics generated by the power supply
transformer.
í
+ 40-program user memory
Up to 40 programs of created equalizer data can be stored in the user memory, when either PEQ or GEQ data is
used.
(Refer to “Memory configuration” on page 8 for details.)
Data stored in memory can be transmitted or received through the RS-485 terminal with the following devices.
€ Another DEQS ог DEQSE (*1)
€ A personal computer which incorporates a RS-485 interface and the DEQS(E) start-up control software.
@ A personal computer with a MIDI interface and DEQS(E) start-up control software. (*2)
*1 To transmit or receive data with another DEQS(E), a DEQS (or equivalent personal computer) is required.
*2 One DEQS5 is required to carry out this method. (Use DOS RS-485 +> MIDI interface function. Refer to page 24
for details.)
4 AES/EBU format digital VO terminals are installed |
In addition to the XLR type analog I/O terminals, which are commonly used in professional applications, digital
T/O terminals for AES/EBU format are also installed.
This kind of digital 1/O terminal makes it easier to combine the unit with systems that transmit audio signals in the
digital range.
e RS-485 control bus
The RS-485 control bus is a bus type communication standard which is used for both transmission and reception.
Employing this communication standard has the following advantages:
€ Expands the system by allowing a maximum of 23 additional DEQS(E)s to be connected in serial, with one
DEQS functioning as a control master. A maximum of 217 DEQS or DEQSE units can be controlled by a
personal computer.
e Wide range installation is enabled, with a maximum of several hundred meters of long distance communication
connections.
e The RS-485 terminal employs a XLR type connector system. Therefore, control data can be transmitted or
received with the cable for XLR type connector systems (*1).
Refer to page 25 explaining “RS-485” for details regarding the communication standard.
*1 Use a cable with impedance characteristics between 90 and 1200 to prevent signal deterioration during RS-485
data transmission (especially for long distance transmissions).

To
match the unit’s communication conditions with those of an external device, the local address (something like
telephone number) should be set.
e
If
multiple
devices
are
connected
through
RS-485,
make
sure
that
no
local
addresses
are
identical.

3. Handling the digital audio input signal
(1) Input setting
The
unit
is
provided
with
a
digital
system
input
terminal,
except
for
XLR
type
analog
I/O
terminal.
When
handling
signals
from
this
input
terminal,
change
the
input
system
to
the
appropriate
setting
on
the
DEQ5
(or
personal computer, etc.) side.
This
is
done
in
“SYSTEM
SET
UP”
in
the
“UTILITY”
menu.
(*)
*
For
convenience,
the
software
functions
explained
in
this
document
(such
as
Mode, Menu,
and
Parameter)
use
the
same
nomenclature
as
DEQS.
(2) Handling the clock signal
When
carrying
out
DEQSE
processing
by
inputting
the
digital
audio
signal
to
the
unit,
clock
setting
is
required
in
the “UTILITY” menu.
It
is
possible
to
operate
the
DEQSE
on
the
clock
signal
extracted
from
the
digital
audio
signal.
However,
if
all
signal
transmission
and
reception
is
carried
out
digitally
(using
the
unit
as
part
of
the
digital
audio
system),
it
is
better
to
operate
the
unit
with
the
clock
signal
of
your
digital
audio
system's
main
control
unit.
Input
this
clock
signal
into
the
“WORD
CLK

SOFTWARE FOR THE DEQ5E
* For convenience, the software functions explained in this document(such as Mode, Menu, and Parameter) use the
same nomenclature as DEQS.
1. Memory configuration
(1) Memory area
The DEQSE has an area where the equalizer setting data (program) is preserved so that it can be recalled anytime.
This is called the “Memory area”.
The DEQSE has GEQ and PEQ equalizer modes. In the memory area, a maximum of 40 programs can be
preserved, no matter which mode they are created in.
When shipped from the factory, initial program data (initial data with flat characteristics) in the two modes are
preserved in the memory area, 20 in the first part and another 20 in the second part. (Each 20 have the same
contents.)
| Two equalizer modes when shipping from the factory
€ 30-band graphic equalizer (GEQ) mode ...... Memory number: 1-20
€ 6-band parametric equalizer (PEQ) mode ... Memory number: 21-40
(2) Edit area
The area where DEQSE program is actually executed or data is modified after recalling the data from the memory
area is called “Edit area”.
A program using a suitable equalizer mode is recalled from the memory area to the edit area. It can be used as it
is, or data can be modified before use.
The new program (after modifying the data in the edit area) is stored in any memory number in the memory area.
Re-write Memory as often as you like.
(3) Initial data area
If all programs are made with only one equalizer mode, you can copy initial data of another equalizer mode from
“Initial data area” to the edit area with the PARAMETER COPY” menu in UTILITY.

3. UTILITY
The Utility menu is used for changing various settings which are not stored in each program [except for (2) Title
Edit].
(1) System setup
Set the following items using UTILITY.
@ ПО MODE ............. 2684 Select one of the audio input systems from the following.
€ ANALOG: Set to ANALOG when receiving an audio signal from an
analog input terminal.
e PRE SEND: Set to PRE SEND when using an AES/EBU I/O terminal
as an insert, as shown in figure I below.
e POST SEND: Set to POST SEND when using an AES/EBU I/O
terminal as an insert, as shown in figure IT below.
e DIGITAL: Set to DIGITAL when receiving a signal from an AES/
EBU YO terminal.

€ IN FORMAT ......................... Select the digital audio input signal format because the DEQSE is only
provided with an “AES/EBU” terminal. Fixed to “AES/EBU”.
© CLOCK oninia ii Set the master clock to operate the DEQSE with the following types.
e INTERNAL: Set to INTERNAL when operating with the
unit's internal clock.
€ AES/EBU: Set to AES/EBU when operating with the
clock signal extracted from the signal
received through the AES/EBU input ter-
minal.
e W.CLK (WORD CLOCK): Set to W.CLK when operating with the clock
signal received through a WORD CLK ter-
minal.
@ EMPHASIS............................. Set whether to implement pre-emphasis or de-emphasis processing in the
process of A/D and D/A conversion of the analog audio signal.
If the input audio signal is set to "DIGITAL", “PRE SEND” or “POST
SEND", the de-emphasis processing ON/OFF setting in this unit's D/A
conversion section is determined here.
e ON: Set ON to implement emphasis processing.
e OFF: Set OFF to not implement emphasis processing.
€ AUTO: Set this when either “DIGITAL”, “PRE SEND”, or
“POST SEND” is selected in I/O mode.
This setting automatically enables de-emphasis process-
ing of the D/A conversion section, in accordance with
the emphasis data of the AES/EBU input signal.

(2) Title edit
DEQSE can store up to 40 programs of created data in its memory. A title name can be assigned to each program.
You can input a total of sixteen letters for one title.
x= The titled data, once you are finished with this menu, is stored together with the created equalizing data in the
memory as a part of the equalizing program.
