User Selectable Audio Profiles optimizes the received audio for specific environments and the personal preferences of the user.[1]
There are two settings, the first of these is Environment for which there are three choices:
- Default – no change
- Loud – enables Noise Suppression and increases speaker loudness by around 8dB so the radio is easier to hear over surrounding noise.
- Work Group – enables Acoustic Feedback Suppression and disables AGC, to minimize feedback loops, when a group of radios are near to each other.
The second setting is Preference and allows the user to adjust the frequency response to suit their listening preferences:
- Default - no change.
- Level 1, Level 2, and Level 3 are intended to compensate for noise-induced hearing loss that is typical for adults in their 40’s, 50’s, and 60’s or over.
- Treble Boost for a brighter or high pitched sound.
- Mid Boost for a more nasal sound.
- Bass Boost for a deeper sound.
Selections can be made from each category independently. Users are encouraged to select the profile which sounds best to them. The Audio Profiles selection are made using CPS or Radio Menu (display radios). For Non-Display and Numeric only Display radios, Environment and Preference settings can only be changed via the CPS or RM.
