Chapter 4: Operation

Chapter 4: operation

introduction

This chapter describes the basic operation of the de-

vice. 
Note that throughout this manual, the abbreviation FS 

refers to sample rate or sample frequency. So, when 

dealing with scaling factors, the following sample rates 

can be written as: 

• 

44.1 kHz = 1 FS; 88.2 kHz = 2 FS; 176.4 kHz  = 4 FS 

or 

• 

48 kHz = 1 FS; 96 kHz = 2 FS; 192 kHz = 4 FS
