AUDIO OPTIONS
Headphone-Off Level Option
This option allows the user to select the signal threshold when the
headphone audio “turns off.” Level settings are - 6, -12, -18, and – 70
dB. The typical setting is –70 dB, which functions as “always on.”
Page Lock Option
When the Page Lock option is selected the page change keys no
longer operate.
Headphone Limiter Option
This option introduces a limiter into to headphone audio circuitry, to
control excessive levels and resulting stress on the ear of the user.
The level can be set anywhere in the range -32dBu to +16dBu using
the Headphone Limiter display on the beltpack. The typical setting is
–6 dBu.
Microphone Type Option
This option allows the user to select the proper setting for the headset
microphone. The available settings are Dynamic (Balanced) Mic and
Dynamic (Unbalanced) Mic. For most Clear-Com and other headsets,
the Dynamic (Unbal) Mic setting is proper.
Microphone Level Option
This option allows the user to set the level of the beltpack’s headset
mic, increasing or decreasing its gain going into the system. For Type I
beltpacks the gain settings are 40, 50, and 60 dB, for Type II beltpacks
the gain settings are 50, 55, 60 and 65 dB. The typical setting is 50 dB.
Headset Options
Two headset options are offered:
• Master Level
• Sidetone Level
The Master Level control accesses a slide bar going from “-“to “+”, and
controls the overall maximum level that can be heard through the
headphones. This gain control permits adjustment among headsets
with different sensitivities, and for different use conditions (quiet studio
versus loud live performance environment). Typical setting is 2/3 to 3/4
of the way toward “+”.
Sidetone Level controls the amount of the user’s own voice (local
sidetone) that is injected into the headphone from the headset mic. It is
activated when the user pushes a talk button or an answer-back key to
