2.INTRODUCTION
This guide describes the operating procedures for the
AXYS® UniAmp 700 power amplifier module.
The UniAmp 700 is a mains-powered power amplifier
module incorporating a DSP (Digital Signal Process-
ing) section. It has a single input and multiple speaker
outputs, the number being model-dependent. The DSP
section acts as a multi-band crossover and also controls
beamforming and beamshaping, per-channel levels,
delays, limiting action, etc.
The DSP may be configured to suit individual applications
and requirements via AXYS®’s WinControl software appli-
cation. This level of configuration should not be confused
with the per-model factory hardware configuration
referred to in the next section (Applicable models and
variants). WinControl also permits constant monitoring
of all units in a multiple-cabinet system during operation.
WinControl is available as download from
http://www.duran-audio.com/software/WinControl.html.
This guide does not cover any aspects of the host loud-
speaker system or installation thereof; these topics are
the subject of a separate Installation Manual, supplied
with each loudspeaker.
APPLICABLE MODELS AND VARIANTS
The UniAmp 700 is the power amplifier module fitted as
standard to the following AXYS®powered loudspeakers:
Target range:
U-16
ScopeG2range:
T-2112
T-2115
UB-25
SourceG2range
T-07
B-07*
IMPORTANT –Each UniAmp 700 is configured
in the factory to suit the loudspeaker type in
which it is to be installed. These configuration differences
are at hardware level and are significant, and it is NOT
possible to interchange UniAmp 700 modules between
loudspeaker types.
The UniAmp 700 has no user-serviceable parts, and no
attempt should be made to remove a module from its host
enclosure. Please contact your AXYS®distributor in the
event of faulty operation.
*Note that model B-07 can also be used as part of a ScopeG2configuration.

AC MAINS
Two Neutrik®PowerCon®chassis connectors are
fitted to the UniAmp 700. The Input connector
(coloured blue) is a Neutrik®Type A, and is intend-
ed for connection of the AC mains supply; the Link
connector (coloured grey) is a Neutrik®Type B, and
is to facilitate connection to another module in an
adjacent enclosure.
Note that the Link connector is not inde-
pendently fused.
User Guide - AXYS®UniAmp Power Amplifier Module , Model 700
The full-load power consumption of the amplifier
module is 700 VA under typical normal operating
conditions. When “daisy-chaining” AC mains between
several enclosures of the same type using the Input
and Link connectors, ensure that the current capacity of
the supply is sufficient for ALL amplifiers in the chain,
and additionally, that the total current drawn by all the
amplifiers does not exceed 20 A (the maximum rated
current of the PowerCon® connectors).
In practice,this means that the maximumnumber
of amplifiers (including the first one) that may
be daisy-chained in this way is six (230 V operation) or
three (115 V operation).
Only wire AC mains connectors according to the table
below:

The PowerCon®connectors are plugged and un-
plugged as shown in the diagram below.
Separation
IMPORTANT – The PowerCon®connectors
should never be plugged or unplugged
when there is power on the connectors, regardless of
whether the amplifier is switched on or not. ALWAYS
ensure that the mains supply is turned off before
inserting or removing either PowerCon®.
AUDIO CONNECTIONS
Two latching 3-pin XLR connectors are fitted for
audio interconnections. The Input connector (female)
is for connection of an audio input signal; the Link
connector (male) is hardwired to the input con-
nector, and facilitates easy connection to another
amplifier in an adjacent enclosure.
200905/UAUG_v1.0
The UniAmp 700’s audio input and output are twin
transformer-balanced, and are designed to operate at
a nominal level of 0 dBV. Balanced system intercon-
nection, using twin-and-screen microphone cables is
strongly recommended.
Wire the audio connectors as follows:

NETWORK CONNECTIONS
Two latching 5-pin XLR connectors are fitted for RS-485
network interconnections. A PC running WinControl may
be connected, via an appropriate interface (either RS-232
to RS-485 or USB to RS-485) to the Input connector, if
control and monitoring during operation are required. The
Link connector (male) is to facilitate easy connection to
another WinControl-supported device (e.g. an adjacent
enclosure).
The network connectors should be wired as follows:
See page 11 for information regarding suitable network
cable types. See Section 7 (Configuring with WinControl) for
more information about network operation and software
options.
User Guide - AXYS®UniAmp Power Amplifier Module , Model 700
4. PRESETS
The UniAmp 700’s DSP section includes 8 Presets;
memory locations in which sets of configuration pa-
rameters can be stored. These permit the loudspeaker
cabinet to be “fine-tuned” to suit different types of
programme material and venue.
When a settings file is loaded into the unit from a
PC, the user can specify in WinControl which Preset
memory it will be loaded into.
RECALLING PRESETS
The simplest method of recalling a previously-saved
Preset is via WinControl. This necessitates a network
connection to the loudspeaker system. Refer to the
WinControl Help files for further information.
If a network connection is not in place, or a PC with
WinControl is unavailable, Presets may be recalled
manually using the Reset & Preset Control button*.
This button is hidden behind a small access hole on
the amplifier module’s conector panel, and can be
accessed with an implement such as a fine jewellers’
screwdriver or a straightened-out paper clip.
A single short press (< 1 sec) on this button will
increment the current Preset number, i.e. if the system
is currently running Preset 2, pressing the button will
load Preset 3. While the button is pressed, the Status
LED will change colour from green to red. Loading of
the next Preset is confirmed by the LED flashing the
appropriate number of times, i.e., it will flash 3 times
when Preset 3 is loaded. Using this method, repeated
button presses will load each Preset in turn.
Note that the amplifier module always
powers-up with the last-used Preset active.
Note also that a long (> 1 sec) button press
has a different function (see following page).
*Please note that this feature may not be available on Target U-16 enclosures with early serial numbers. Please contact your
AXYS®dealer for more information.

5. RESET
One of the eight Preset memories acts as a “default”
memory, referred to as the “preferential preset” by
WinControl. Users are recommended to store a known
base configuration in this Preset, and to protect it via
WinControl. This Preset may be reloaded by a long (>
1 sec) press on the Reset & Preset Control button (but
see note on previous page regarding early U-16 serial
numbers).
Resetting the UniAmp 700 may also be carried out via
WinControl; see the WinControl Help files for more
information.
6. OTHER
STATUS LED
The bi-colour Status LED has several functions:
1. To indicate that power is being applied to the unit,
the LED shows green for normal operation.
2. To indicate a fault state. The conditions for a fault
state are defined as part of the WinControl settings
file. If the conditions are met, the LED illuminates
red and an error indication is also communicated
via WinControl.
3. To confirm which Preset is being loaded (see
Recalling Presets, Section 4).
4. Unit identification: if the LED is set (in software) to
duplicate the functions of the LED on the front of
the enclosure, it will also confirm unit identity when
requested by WinControl.
200905/UAUG_v1.0
CIRCUIT BREAKER
The amplifier module’s mains on/off switch is also a
resettable 6.3 A circuit breaker. If the module draws
current in excess of the rating from the AC mains (as
may happen in a fault condition), the circuit breaker
will trip, disconnecting the power. The fault condition
should be identified and rectified before attempting
to reset the breaker. Note that under extreme fault
conditions, it may not be possible to reset the breaker.
There are no user-replaceable fuses within the Target
System amplifier module.
COOLING
Loudspeaker enclosures equipped with the UniAmp
700 include fan-assisted cooling of the electronic
assembly. The direction of airflow is from intakes
at the front of the enclosure, with exhaust through
slots in the connector panel. The fan is automatic
and is controlled via a “whisper algorithm” via the
DSP section, which adjusts the fan speed according
to temperature and input signal level. Care should be
taken in installation not to restrict the airflow.

7. CONFIGURING WITH WINCONTROL
Correct operation of a UniAmp 700 module may be
confirmed using WinControl software.
A full description of WinControl is beyond the scope of
this manual and further information is available in the
application’s Help files. Instructions on how to install
WinControl on a PC are included with the Program Set.
Instructions on the use of the AXYS®RS-485 interface
are included with the interface itself.
CONNECTING TO A PC
The PC connects to the amplifier module via an RS-
485 interface adapter. (Two versions of adapter are
available from Duran Audio, for connecting to PCs
either via a USB or an RS-232 port). Use either a 5-pin
XLR female to 5-pin XLR male cable or a 9-pin Dsub
to 5-pin XLR male. These cables (5 m in length) are
supplied with the WinControl Program Set, the type
depends on the RS-485 interface type. The RS-485
interface should then be connected to either the PC’s
9-pin COM port (in the case of a RS-232 to RS-485
interface) or a USB port (in the case of a USB to RS-485
interface).
BASIC SOFTWARE OPTIONS
WinControl allows the various parameters of the
UniAmp’s DSP section to be set according to the
installer’s wishes. This enables the performance of
the loudspeaker enclosure to be accurately optimised
to suit both the venue and the type of programme
material being handled (speech, rock, opera, etc.)
In the case of the Target U-16 enclosure, AXYS®DDA
(Digital Directivity Analysis) may be employed to model
the room’s acoustics accurately, and the results of this
analysis then used to optimise the array’s performance.
User Guide - AXYS®UniAmp Power Amplifier Module , Model 700
The particular set of parameters which can be adjusted
viaWinControl varies with loudspeaker model.Typically,
it includes delay, gain and multi-band parametric EQ.
In addition to the parameters determining the audio
performance, the various Preset memories may have
alternative configurations stored in them, and recalled
as required. Unit monitoring may also be configured,
with the conditions for a fault state to be signalled
being registered. Additionally, multiple loudspeaker
units may be ‘grouped’ together in software, allowing
very rapid adjustment of the overall loudspeaker array
performance.
Full details of the options available within WinControl
are available in the application’s Help files.
