Welcome
Thank you for choosing a StormAudio Immersive
Sound Preamp/Processor. This guide provides step-
by-step instructions for quickly setting up your ISP to
meet a basic Theater configuration.
The ISP range shares the same backbone, but models
differ by the options that are installed. This guide will
describe a basic setup valid for any version of the
Immersive Sound Processor.
We continuously strive to improve our products.
Some features might have thus been added or
improved recently. Please check our website: https://
www.stormaudio.com to get access to the Firmwares
and documentation, and keep your ISP up to date by
upgrading it to the latest available Firmware package.

When in the Theater Configurator, you will be able
to define each layer of the speaker installation: base,
height and top layers.
1. Choose using the left and right arrows which
layout you expect for the layer.
2. For each speaker, you can define whether full
bandwidth or multiway, with up to 4 ways
definable.
3. The Center channel can be turned to Phantom
mode, the signal being played in Left and Right
channels.
4. Top speakers can be defined as Dolby Atmos
Enabled for the case up-firing speakers are used.
In such case, select the base speaker location.
Keep «None» for normal down-firing speakers.
5. For each speaker, you can define whether
replication is required. It is often used for multiple
subwoofers use or multiple rows of surround
speakers.
6. Press Next to reach the next layer and follow
again steps 1 to 6 until all three layers are defined.
7. At the end, a summary of the Speakers
Configuration is shown.

In this part, we will cover the configuration of the
speakers in the installation following Main Speakers
tab selection.As systems might easilyget complicated,
the Quick Guide will only focus on a basic use case
where full bandwidth passive speakers are used. We
will not treat the specific multi-ways speakers.
Also, we will consider multiple rows of surround
speakers as well as multiple subwoofers.
For the case you need a different configuration, we
invite you to refer to the Owner Manual providing

Adjust the Bass Management
Once configured, the Theater is presented in Edition
mode. In this Quick Guide we will only consider the
Standard Bass Management setup:
1. For each Theater, it is possible to define multiple
audio profiles (all Theater settings). By default, a
«New Profile 1» is created.
2. Define the Size of each of your Speaker between
Small, Large and «Large and Sub». Small will
filter the low frequencies and direct them to the
Subwoofer. Large will maintain full bandwidth,
while «Large and Sub» will also direct the Bass to
the subwoofer channel.
3. When in Small, adjust the filter crossover frequency
between speaker and subwoofer.
4. When in Small, adjust the slope between 12dB,
24dB, 36dB and 48 dB/octave (Linkwitz-Riley and
Butterworth types).

Output Mapping matches your connections (see
section 6).
3. Select the Narrow Band pink noise signal and
activate the Noise Generator, having first made
sure the Master Volume is not at a too high level,
such as < -30dB. Using the Group +/- button,
navigate through each Speaker. Use the normal
Pink Noise for the Subwoofer adjustment.
4. Adjust the Level for each Speaker using a SPL
Meter. We recommend to adjust the Levels with 75
to 85dB(C) average sound pressure as reference.
5. It is possible for each Speaker to adjust up to 20
Parametric EQs. Consult the Owner Manual for
more details.
