BIT TUNE, KEY FEATURES

To describe the bit Tune and its functions, it would be easier and faster

to describe what is not possible to do, but this would not convey the

breadth of possibilities…, so let’s progress step by step.

What is included?

The bit Tune system comes packaged in a professional carrying case,

complete with all of the accessories required for its use. This case ensu-

res safe transportation during events or trips outside of the installation

center, and properly secures all materials, such as the microphones that

require particular attention.

HSM - Hearing Simulation Mic. This is the most important component

and is where the Audison research team focused most of its work, along

with the acoustic analysis software. It is a disc-shaped microphone

with 5 high-quality microphone capsules arranged around half of its

circumference. The most important design element of the HSM was to

simulate the “head” of the listener from the listening position, hence

the name Hearing Simulation.

The simulation of human sound perception is accurate, thanks to precise

design choices: the overall diameter of the disc shape approximates the

distance between the two human ears; number and placement of the

capsules are designed to reproduce the polar response of the human

auditory system. Through the bit Drive algorithm integrated within the

PC software, the signals acquired by the human hearing characteristics

of HSM microphone are processed, setting conguration parameters for

the processor, making the response of the audio system “natural.” The

unique mounting system provided places the microphone array in the

perfect position.

LPM - Level and Polarity Mic. This is a single-capsule microphone,

used for setting system levels and for checking the acoustic phase

of the speakers. The “strap-type” mounting system provided places the

microphone perfectly between the two front headrests.

This small microphone can easily be removed from the mounting system

in order to check the phase of a speaker, making best use of the “polarity

check” wizard in the software.

CMU - Central Measurement Unit. This is the “brains” of the system,

acting as an interface between the acquired/generated data and the

PC based management software. It is equipped with a set of inputs

and outputs to the car audio system and USB connection to control the

Audison bit processor.
