The On Tour XTB is a Bluetooth Portable Loudspeaker.  Its function is to provide audio 
amplification from audio, USB or a Bluetooth paired device. The EUT was exercised by a Bluetooth 
paired device transmitting a stream of MP3 file formatted audio music. If the music is disrupted as 
indicated by a break in the music, or there is loss of functionality, this may be considered a failure 
when the On Tour loudspeaker is device affected by test. The CD player providing Pink Noise was 
used in the test when the power supply is primary expectation of fault as in Surge immunity testing, 
Dips and Drop-Outs and Voltage Variations. 
 
The EUT’s performance during test was evaluated against the performance criterion specified by 
applicable test standards.  Performance results are detailed in the test results section of this report.

The following design modifications were made to the EUT during testing. 
 
Ferrites, denoted by inductors, were added by the client, Harman Multimedia, to solve an immunity problem 
with ESD and CMRFI.
