Introduction and Key Features

Introduction

The OUTLINE Genius series of loudspeaker management systems represent the current state-of-the-art.

Taking advantages of the latest advances in analogue to digital conversion and digital signal processing

technologies the units achieve performance levels that have only recently been made possible.

This modern design is combined with OUTLINE Factory Presets to deliver the optimal match for OUTLINE

cabinets and systems. These presets allow the user to simply achieve the best possible performance from any

OUTLINE loudspeaker.

Key Features

•Outline minimal signal path design

•Sonically superb ADC / DAC combination; a carefully matched pairing of the best devices from Burr

Brown and Wolfson

•Newly released family of Analogue Devices SHARC DSP

•Extended bandwidth; 96kHz sampling frequency provides for a nominally flat response to 40kHz.

•Parameter knob and LCD provide a rapid, user-friendly control interface

These key features should be focused on the OUTLINE unit – these are examples / ideas really.

The User Guide

This user manual gives a progressively more detailed description of the functions of the OUTLINE Genius

series loudspeaker management systems. A single page quick reference guide is provided for those users who

are experienced with this type of equipment and just need to know how to ‘drive’ the front panel.

A detailed explanation of the front and rear panel controls and indicators is contained in the next section. The

final section describes each individual function or feature with annotated images explaining its’ use. Where

appropriate, the LCD is shown to further elaborate on the units’ operation.

To complete the manual a reference section is included, describing the technical performance of the device

complete with graphs of filter responses and details of the Factory Presets and their configuration.

Input Signal Indicators

A set of three pairs of LEDs indicate signal present, +4dBu and input clip for each channel. The signal present

LEDs operate at approximately –40 dBu, giving a useful indication of even relatively low input signal levels. The

+4 dBu LEDs are intended to show nominal operating level and can also be useful for setting system gain

structure. Clip LEDs warn the user of input overload and operate at +19 dBu.

Preset Store and Recall

These controls provide access to the 45 presets stored within the device. Pressing the store button allows the

user to name a preset and choose which memory location it will be held in. Pressing store button again

completes the process. The Recall function operates in a similar way, pressing the recall button allows the user

to select which preset they require, pressing the button for a second time, then confirming, recalls the new DSP

settings.

Note that presets cannot be stored or recalled when Secure mode is activated.

Channel Select Buttons

The currently selected channel is displayed on the top left hand corner of the LCD. Pressing the channel

buttons scrolls through the available input and output channels and finally through the utility functions and back

to the default screen. If operating a stereo linked preset, the channel name will indicate the channel pairing. For

example ‘A+B’ means both input A and B parameters. The name of the output will be shown briefly at the top of

the display when stepping onto an output.

Edit Select Buttons

The currently selected edit parameter page is displayed on the bottom left corner of the LCD. Pressing the edit

select buttons moves through the available parameters for the current input or output.

Text Display

Preset, channel, parameter and status information is shown on the 2x 24-character text display. In most screens

the currently selected channel is displayed on the upper line and the edit parameter on the lower line. To

simplify the display and enhance security, some parameters or parameter pages are omitted when not relevant.

Parameter Knobs

Three velocity sensitive parameter knobs are used to adjust parameters shown on the display. Up to three

parameters at a time are displayed on the screen. The parameter name is shown above the parameter value in

each of the three screen sections. The parameter knobs have a fixed association with the screen sections; the

rightmost parameter knob adjusts the rightmost parameter and so on.

Output Signal / Limiter Indication

Two LEDs are provided for each output channel. These show the signal level relative to the limiter threshold.

The yellow LED will light when the signal is 6dB below the threshold and the red warning LED will light when the

limiter threshold is reached.

Mute Buttons and Status LEDs

Each output has a mute button and associated mute status LED. Pressing the button toggles the mute on and

off. Note that the mute buttons do not function when the Secure mode is activated.

Secure Button (on the rear)

A momentary button is fitted behind the rear panel, between the output XLRs and the RS232 port. When

activated, this will disable all the front panel controls so they cannot affect the signal path, making the unit

secure against tampering. When in secure mode, the indicators still operate normally. Note that the

communications port is still active in secure mode.

Rear Panel

Power Inlet

The OUTLINE Genius series unit should be connected to a suitable mains electricity supply using the cable

supplied. The processor has a switch mode power supply that is capable of operating with a nominal mains

voltage of 85V to 240V, 50/60Hz without re-configuration.

Network Expansion Port

Where a future network card can be fitted.

Audio Input Connectors

All audio connections are fully balanced and wired pin-1 ground, pin-2 hot & pin-3 cold. The two inputs have pin-

1 connected directly to the chassis and feed the signal processing chains. If an unbalanced source is used, a

connection should be made between the pin-3 ‘cold’ signal and the ground connection of the unbalanced

source.

Audio Output Connectors

The processed outputs are impedance balanced, and wired pin-1 ground, pin-2 hot and pin-3 cold. An

unbalanced input may be driven by connecting pin-3 ‘cold’ signal to the ground connection of the unbalanced

destination input. Note that output pin-1’s are ground lifted at audio frequencies but connected to ground at RF

for good EMC performance. The intention being that the amplifiers the processor is driving should be

responsible for the grounding of their input cable shields.

Communications Port Connector

A Genius series processor may be controlled entirely from another controller, typically a Personal Computer,

running an application that is compliant with the ObCom standard. Connection will normally be made to the

controller via this serial port connector. This port is also used for updating the firmware in the unit.

Note that the communications port is NOT disabled when the front panel is made secure using the secure

button.

Operation

Starting up

The unit will energise as soon as power is applied to the IEC inlet; there is no power switch. During the start up

process the firmware application model number and version numbers are displayed and the outputs are muted

until the unit has completed its internal checks. Once the start-up routines are complete and the unit is ready to

pass audio. The DSP signal path will be restored to the current settings when it was last powered down and the

audio signal is gradually ramped up to its correct level.

Selecting a Factory Preset

The Genius series processors have a library of Factory Presets designed to suit a range of OUTLINE

enclosures.

Factory Presets contain some parameters that are fixed and hidden from view; the remainder of the DSP

parameters are available for user manipulation. The number and type of hidden parameters is dependant on the

Factory Preset, typically crossover frequencies, output delay and some EQ’s are hidden; those settings that are

a function of the loudspeaker cabinet design and should not require adjustment for different applications.

To recall a Factory Preset for a particular cabinet or system, press Recall and use the left hand parameter knob

X to scroll through the available factory preset locations (as indicated bu a box symbol after the preset number).

Once the appropriate preset has been selected press recall again, at which point you will be asked to confirm

the action by pressing recall for a third time. This is to guard against accidental recall of Presets.

Factory Presets are locked so they cannot be over-written. The user can, however, store an edited version of a

Factory Preset in any free preset location.

Details of all the Factory Presets including output designations can be found in Appendix A.

Creating a Crossover

In addition to the Factory Presets the unit has two further ‘Base Presets’; mono and stereo. These Base Presets

are stored in locations 1 and 2 respectively, they can be used to develop settings for any loudspeaker

combination and are recalled in the same way as the Factory Presets described above. These Presets are also

locked but the user can name and store their own edited versions in any free preset location.

Navigation and Viewing Parameters

Many of the processing elements in each input and output path have features that may be controlled by the

user, such as gain, frequency or limiter threshold. We call these adjustable features parameters.

A parameter may be adjusted when it is displayed by turning one of the three-parameter knobs. Each of the

three-parameter knobs is associated with a zone on the display. Adjusting the leftmost parameter knob will

change the value of the parameter showing in the leftmost zone of the display and so on. Turn a knob clockwise

to increase the value of a parameter, or anti-clockwise to decrease it. The knobs are velocity-sensitive so

turning a knob rapidly will cause the action to ‘accelerate’, so the value changes more rapidly.

Navigation

The DSP parameters are organised by channel. The currently selected channel is shown in the top left hand

corner of the display. You can navigate between the channels by pressing the channel buttons. Pressing the

channel buttons will scroll through the channels, utilities and back to the default screen. When using a Preset

that is stereo linked, the channel selection will reflect this. For example ‘1&4’ indicates outputs 1 and 4. When

navigating onto an output channel, the usage of the output, as define in the factory preset, will be shown briefly

at the top of the screen.

PARAMETER

Pressing the edit navigation buttons gives access to the various pages of parameters available for each

channel. The currently selected page is shown in the bottom left hand corner of the display, this is omitted on

some pages where the function is obvious. The screen shows up to three (normally related) parameters for a

given part of the processing functions on a given channel.

The edit buttons allow you to scroll, in either direction, through the different processing pages for a given

Channel. When you go past the last page, you will be returned to the default page.

The channel buttons allow you to scroll, in either direction, through the input and output channels, whilst trying to

maintain the currently viewed processing block. If the channel you scroll to does not have the currently viewed

processing block, the next one will be shown instead.

NB. When the unit powers-up, the settings will be the same as those when the unit was last switched off.

Presets

The device contains a total of forty-five user and Factory Presets. The user cannot overwrite the basic mono,

basic stereo or Factory Preset programs.

Preset Recall

To select an existing Preset, press the Recall Button so the indicator above it illuminates. Turn parameter knob

X until the required Preset number is shown on the display. Factory presets are indicated by a box symbol

appearing after the preset number. Press the Recall Button again to activate the Preset. Pressing any other

button will cancel the operation.
