10.4 _CALIBRATE THE ACTIVE CROSSOVERS (OPTIONAL)
This chapter explains how to calibrate the active crossovers included in the Altitude
16
. It
assumes that you are familiar with active crossovers and multi-amplified speakers and
is not intended as a course. If you are not using the active crossover functionality of the
Altitude
16
, please skip to the next chapter.
IMPORTANT NOTE: Carefully read the entire chapter about the Altitude
16
Essential Tools and Settings that you will
be using throughout the calibration process.
NOTE: Internal 48 kHz clock modes must be used for calibration.

10.4.1 _OVERVIEW OF THE CROSSOVER SETUP PROCEDURE
The overall setup and calibration process of the Altitude
16
active crossovers is performed
through two different tools:
• Use the Speaker/Room Setup Tool to:
• Configure the number of ways and the crossover frequencies;
• Verify the routing of the Altitude
16
outputs to the correct drivers.
• Use the Setup/Active Xovers page of the Advanced Settings interface to:
• Configure the advanced crossover settings such as specific frequencies for each driver and the type of filters
(optional).
• Use the Processor/Meters page to adjust the master output level:
• Perform the automated calibration of the active crossover: this will automatically determine the level, delay
and polarity of each driver;
• Manually adjust levels, delays and polarities of each driver;
10.4.2 _CONFIGURE THE ADVANCED SETTINGS (OPTIONAL)
The Altitude
16
includes the following advanced crossover settings:
• Types of filters: Bessel order 2, 3 and 4, Linkwitz-Riley order 2, 4, 6 and 8, Butterworth order 1, 2, 3, 4, 6 and 8;
• The specific crossover frequency for each driver;
• Level, Polarity and Delay adjustment on each way (driver);
