1. Introduction

Polycom InstantDesigner™ release 2.0 is a revolutionary new way for

A/V integrators and consultants to quickly and accurately design audio and video

conferencing systems and sound reinforcement applications, with Polycom

Vortex®audio and video products. A new addition to our Conference Composer™

design software for Windows®, the patent pending Polycom InstantDesigner

guides the system designer through the steps required to create high performance

Vortex audio conferencing and sound reinforcement solutions.

The A/V integrator or consultant simply chooses the necessary inputs, outputs

(including the new Polycom VSX™ 7000 or VSX 8000 video codecs) and

optionally the sound reinforcement zones needed for the desired system, and

Polycom InstantDesigner automatically selects the appropriate Vortex devices

necessary to implement the system, maps the inputs and outputs to the devices,

and creates the Conference Composer design files required to implement the

design. It is easy to upload these design files to the Vortex devices to complete

the configuration. All of this can be done within a matter of minutes.

The Polycom InstantDesigner handles all the details of creating zone to zone

gains for sound reinforcement, configuring the acoustic echo cancellers,

interfacing to common audio and video equipment, bussing between devices,

configuring presets, creating volume control macros, and preconfiguring logic ports

for push to talk microphones.

Polycom InstantDesigner will change the way audio and video conferencing

systems are designed. The immediate benefits of using Polycom InstantDesigner

include

• Dramatically reduced design time – from hours to minutes (or less) which

means more profit to the A/V designer

• More consistent A/V designs – there is now a “Vortex expert” included with

every product purchased

• More satisfied end-users due to quicker and better installations

• Reduced learning curve for A/V specialists to confidently design larger

systems for any type of application.

Read more to learn how Polycom InstantDesigner will change the way you design

audio and video conferencing systems.

2. What Polycom InstantDesigner does for you

Polycom InstantDesigner release 2.0 encapsulates the design expertise of the

Vortex engineering team and the experience of thousands of successful audio and

video conferencing installations. We have learned both the easy way and the hard

way what works and how to best use the Vortex products. By making Polycom

InstantDesigner available to you, the A/V specialist, we want to make your job

easier and allow you to spend more time doing the things that can help your

design and integration firm be more profitable. To give you an idea of how much

the design process can be accelerated, below is a partial list of what Polycom

InstantDesigner will do for you. With just a few mouse clicks, Polycom

InstantDesigner will automatically:

• Select the Vortex equipment necessary to implement the system

• Map the input and output equipment to Vortex inputs and outputs (e.g.,

lectern microphone is input 1 on Vortex EF2280:00)

• Set the input and output gains in the Vortex required to interface to the

selected input and output equipment (e.g., most video codecs typically

require 10dB of input gain, and 5dB of output attenuation)

• Configure the automatic microphone mixer for linked operation for larger

systems

• Create all the matrix crosspoints necessary to use the resulting system

(e.g., local audio is sent to the remote site and remote audio is played back

into the room)

• Create loudspeaker zones for sound reinforcement and allow you to specify

the microphones that are part of that zone and reinforced into other zones

• Make it easy to modify the zone to zone crosspoint gains needed for sound

reinforcement across zones

• Configure all the bussing across linked devices (e.g., local microphones are

automatically sent to all devices), including sound reinforcement zone gains

• Configure the acoustic echo cancellation (e.g., the echo canceller reference

is configured and all linked devices are configured to use the bus reference)

• Customize the text labels for all inputs and outputs including the bussing

signals

• Save the settings to Preset 16 and set the power-on preset on all devices

• Create macros for muting, unmuting, and volume control

• Create logic assignments making it easy to connect push-to-talk

microphones or other hardwired control systems

• Create a project summary of the wiring connections and necessary

equipment

• Create formatted PDF reports of your system configurations

• Create a zone to zone sound reinforcement summary report

• Create a signal routing report so you can see how the signals are routed

and bussed to create the appropriate sound reinforcement zones

• Create DXF drawings of your designs

• Upload the Conference Composer project to your Vortex devices

The list keeps growing and growing. Imagine what you can do with Vortex

products now – perform more conference designs with your current team, create

new conferencing applications, build more expertise within your team, etc. If you

haven’t tried the Vortex products – you can’t afford not to.

Sit back, grab a cup of coffee, and learn how we are trying to make your job

easier.

3. Getting Started with Polycom InstantDesigner

To use Polycom InstantDesigner simply start Conference Composer. You will be

presented with the screen shown in Figure 1.

Figure 1. Conference Composer startup screen.

From here there are three choices

1. Autoscan for Devices retrieves the settings from the Vortex devices and

puts them into Conference Composer– this requires that you be connected

to a Vortex via an RS232 connection.

2. Create Project with Polycom InstantDesigner begins the instant design

process.

3. Open Existing Project opens a previously designed Vortex project.

Selecting Create Project with Polycom InstantDesigner will start the Polycom

InstantDesigner process and bring you to the screen in Figure 2. If you are

already running Conference Composer you may start Polycom InstantDesigner by

selecting Polycom InstantDesigner from the Project menu or using the keyboard

shortcut of Ctrl-i.

Please note that at any step in the Polycom InstantDesigner process, the Polycom

InstantDesigner information can be saved to disk by clicking on the floppy disk

icon. This is a useful and recommended step in case changes need to be made to

the configurations within Polycom InstantDesigner after the initial design process

is complete.

Clicking the help icon will provide a step by step instruction guide for using the

InstantDesigner software.

From a high level perspective as shown in Figure 3 there are two paths through

the InstantDesigner software, depending on whether sound reinforcement is

required.

Figure 3. The steps of using the InstantDesigner software – either 6 steps or 9 steps are

required depending on whether sound reinforcement is required for the design.

As we shall see, there are either 6 steps (without sound reinforcement) or 9 steps

required to design the complete audio and video conferencing system.

Click Next to start the wizardry of the Polycom InstantDesigner.

Step 1 – Select Inputs

The first step of Polycom InstantDesigner is to select the types and quantities of

inputs that are required in the audio design. The types of inputs that can be

selected include:

• Microphones – including table, ceiling, lectern, and wireless microphones

• Program audio – including both stereo and monaural consumer and

professional playback devices such as DVD players and VCRs

• SoundStation VTX 1000™ for wideband telephony

• PSTN Telephone line interfaces for narrowband telephony interfaces

• Video codecs – including Polycom VSX™ 7000, VSX 8000, ViewStation®,

and iPower™

Select the types of input, such as Microphone and Table, choose the quantity,

adjust the text label, and then click Add Input. This will add the selected items to

the Selected Inputs text box as shown in Figure 4.

Figure 4. Polycom InstantDesigner Step 1 – Select Inputs.

In this application note, we will design a system that includes 12 table

microphones, a lectern microphone, two wireless microphones, a VSX 8000 video

codec, an analog phone line, stereo program audio, a monaural recorder, and an

assistive listening device. This room might look like the room in Figure 5.

Please note that at any time during the Polycom InstantDesigner process you may

save your design to an InstantDesigner template file (*.idt) by selecting the floppy

icon on the lower left of the screen. The design specifications that you have

created up to that point can be restored from a saved file by selecting the folder

icon on the lower left of the screen. These Conference Composer template files

are different from the files that Conference Composer creates and can be used to

share your design intent with your team, subcontractors, etc. before the complete

Conference Composer project file is created.

After the input selections have been made, select Next to go to Step 2 – Select

Outputs.

microphones, stereo program audio, telephone interface, and a Polycom VSX 8000 video codec.

Step 2 – Select Outputs

The second step of Polycom InstantDesigner is to select the outputs that will be

used. By default, some outputs will already be selected, such as a telephony

output and a video codec output, if their respective inputs have been selected.

This automatic selection is shown in Figure 7.

The types of outputs that may be added to the system include:

• Assistive listening
