The RTA (Real Time Analyzer) measurement is the fundamental measurement for audio systems in that, through the
microphone, checks the acoustic effect that reaches the ears of the listener.
It takes into account all the parameters of the audio system, including the acoustic response of the vehicle’s passenger
compartment. However, a linear response does not indicate good listening, because the human ear perceives sounds
in a nonlinear way.
But it represent an essential starting point for the acoustic refinement of the audio system.
The RTA measurement is appropriately considered in the calibration procedure (Auto Eq + Auto Time Alignment).

Install the HSM inside the passenger compartment of the vehicle as described in
section 4
IMPORTANT:
In the processors you
should enable the AUX input
if you use a bit Ten/D or AUX1
if you use a bit One through
PC software. This can be disabled
after the measurements. If you want to
connect the bit Tune to AP bit amplifiers to
perform measurements, but the AUX input
port is already occupied, you can use the
OPTICAL input port
(see section 4.5.6)
