Frequently Asked Questions

â–º Does VoiceMax use signal clipping to achieve compression?
No, signal clipping causes distortion and produces audio that sounds
“fuzzy�. VoiceMax uses a sophisticated automatic gain control circuit
to maintain audio at a constant level with distortion well below 1%.


â–º Can I install the VoiceMax module myself?
Yes, but for optimum results the installer should have access to an
oscilloscope. The oscilloscope will be used in adjusting the output
level of the VoiceMax module so that the transmitter will not over
modulate.


â–º Can I use a power or condenser microphone with VoiceMax?
No. Due to VoiceMax’s high gain we recommend that only non-amplified
dynamic type microphones be used. Power and condenser microphones
contain amplifiers that are generally incompatible with VoiceMax.
There are many aftermarket microphones that work well with VoiceMax...
such as Astatic 611L, Astatic 636L, Astatic 651, and others.


â–º What is a noise gate?
A noise gate is a feature that allows low-level sounds to be subdued.
This is very useful in a mobile environment, where road noise can be a
problem. VoiceMax’s noise gate threshold level is adjusted once during
installation, based on user preference.


â–º Does VoiceMax require a battery?
No, the power required for the VoiceMax module is extremely low, and
is derived from inside the transceiver.


â–º How big is the VoiceMax module?... And will it fit inside my radio?
The size of the VoiceMax module is 1.6� x 1.6� x 0.32� utilizing
surface mount electronic technology. This small size should fit inside
most transceivers.


â–º How will I know the VoiceMax module is working?
VoiceMax has a modulation indicator LED that flashes in sync to audio
applied to the transceiver’s microphone. This LED is viewed during the
adjustment procedure, to make certain VoiceMax’s levels are set
properly for your transceiver.


â–º Should the VoiceMax module be operating all the time?
Yes! The VoiceMax module was designed to be active whenever your
transceiver is operating. This allows you to take advantage of
VoiceMax’s performance boost every time you transmit.
