of a main theater except that channels are always

Dirac Live
Dirac Live is a highly advanced calibration tool
which uses sophisticated mixed-phase lters to
compensate for loudspeaker and room deciencies
in order to provide optimal acoustic performance
of your theater. The Dirac Live 2.x license is free
of charge and available on Dirac Website aer
registering on Dirac Live website (https://live.
dirac.com/register/) and calibration kit are usually
purchased by the installer through their dealer.
All Theaters, zones, and child theaters can be
calibrated with Dirac Live. Presuming you have a
calibration kit, prepare your ISP for calibration by
following the steps below.
1. Dene Speakers
For each theater or zone (except Headphones
and Downmix) you will calibrate using Dirac
Live, ensure that you have correctly dened
each speaker’s Size/Filter, Frequency and
Slope, multi-way speaker denitions and other
Bass Mangement parameters. (“Individual
Channel Adjustments” on page 17)
2. Download and install Dirac Live 2.x
Calibration Tool Soware
You can download a Mac or PC version of the
soware at https://live.dirac.com/my-account-
download/ or on the StormAudio Client Portal
(www.stormaudio.com).
Install the soware on the laptop you will use
to calibrate the ISP. Use the Dirac account
credentials as login in the tool.
3. Prepare Calibration Hardware
Although we recommend using the kit
we provide which includes the UMIK-1
USB microphone, other hardware may be
compatible with the Dirac Live Calibration Tool.
This guide will only cover our hardware.
Connect the UMIK-1 to your laptop. Note the
serial number on the microphone. Navigate to
https://www.minidsp.com/products/acoustic-
measurement/umik-1. Enter the serial number
to obtain your unique calibration les.
4. Choose Theater or Zone to Calibrate
From the Main Speakers (A) menu in the ISP
web UI, EDIT (B) the theater or zone you wish
to calibrate.
5. Select Base Prole
Select the prole which will serve as the
basis for your Dirac Live calibration from the
dropdown menu.
6. Setup Dirac Groups
It is recommended that if your theater includes
multiple subwoofers, manually correct levels,
EQ, and delay for each. Then, group all the
subwoofer channels together for the purposes
of Dirac Live calibration. Also, manually build
any crossover and EQ settings for active
loudspeakers. Group separate elements of a
single active loudspeaker together e.g. Low,
Mid, and High components of the LEFT FRONT
should be in a single generator group. Click the
SETUP button (C) beside the Dirac button.
Channels that should play together during
calibration should share a group number (D).
