User Guide - AXYS ® UniAmp Power Amplifier Module , Model 700

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 Processing) 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 application. 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 loudspeaker 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

Scope G2 range:

T-2112

T-2115

UB-25

Source G2 range

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 Scope G2 configuration.

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 intended 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 independently fused.

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 maximum number 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:

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).

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.

The UniAmp 700’s DSP section includes 8 Presets; memory locations in which sets of configuration parameters 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.

User Guide - AXYS ® UniAmp Power Amplifier Module , Model 700

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.

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.

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.

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 5pin 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).

The particular set of parameters which can be adjusted via WinControl 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.

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.
