9.4 _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 carefully the entire chapter about the Altitude
16
Essential Tools and Settings that you will
be using throughout the calibration process.
!
NOTE: Master 48 kHz clock modes should be used for calibration (Master 48kHz highly recommended).

9.4.1 _OVERVIEW OF THE CROSSOVER SETUP PROCEDURE
The overall setup and calibration process of the Altitude
16
active crossovers performed through two dif-
ferent 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.
• The first 2 steps of this process were explained in the previous chapter. This chapter explains the next steps.
9.4.2 _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 and 4; Butterworth order 2, 3 and 4;
• Specific crossover frequency for each driver;
• Level, Polarity and Delay adjustment on each way (driver);
