FM+ C
For speaking and other voice applications, Voice is the preferred mode of operation.
This can be set through the web page ONLY.
Custom Audio Preset
If the three preset configurations do not meet the needs of the venue, the Custom audio preset can be used. The
custom preset allows the user to adjust the High-Pass Filter cutoff frequency, Low-Pass Filter cutoff frequency,
and choose the Compression Ratio. If the audio preset is changed from Custom to Music, Hearing Assist, or Voice,
the Custom settings are still saved for use in the future. The custom settings are overwritten when the preset is
changed.
This can be set through the web page ONLY.
High-pass Filter
A High-pass Filter cuts off low frequencies and lets high frequencies pass through. The pole frequency chosen
is the point where the cutoff takes effect. The high-pass filter will help to remove low frequency noise from
the transmitted audio signal, such as room noise, a line hum, or breath accents picked up from an improperly
installed microphone. Available frequencies are: 31, 63, 80, 100, 125, 160, 200, 250, 315, 400, 500, and 630 Hz.
This can be set through the web page ONLY.
Low-pass Filter
A Low-pass Filter cuts off high frequencies and lets low frequencies pass through. The pole frequency chosen
is the point where the cutoff takes effect. The low-pass filter will help to remove high frequency noise from the
transmitted audio signal, such as hiss in the audio line as a result of room noise, sharp speech sounds, or other
uncomfortable high frequency sounds. Available frequencies are: 3.5, 4.0, 5.0, 6.3, 8.0, 10.0, 12.5, and 16 kHz.
This can be set through the web page ONLY.
Dynamic Range Compression
Dynamic range compression reduces the volume of loud sounds and amplifies soft sounds. This type of
compression is typically used for voice and hearing assistance applications for a listener who has difficulty
hearing the quiet sounds of an audio broadcast.
For listening to music programs, concerts, etc., lower compression ratios or no compression is generally used.
The FM+ C has three selectable modes of compression: 1:1 (compression off), 1.5:1 (low compression) or 2:1 (high
compression).
For applications such as music and voice, where high audio quality is desirable, 1:1 is the recommended mode of
operation. For hearing assistance or applications where the transmitted message is critical for listening, 1.5:1 or 2:1
is recommended.
This can be set through the web page ONLY.
NOTE: The FM+ C is shipped from the factory at a 1:1 compression ratio (no compression).
NOTE: Some hearing impaired people cannot tolerate as loud of a sound as those with normal hearing.
Using compression can help protect those users. However, compression also can make audio sound flat.
Only use compression when it is the best choice for the listeners.
FM Output Power
The selectable transmitter power levels are Full, Medium (-10dB), Low (-20 dB), and Off. By default the FM+ C is set
to full power mode. For general listening applications, full power is the preferred mode of operation. Full power
provides an operating range of up to 1000 ft (dependent on the environment and antenna installation).
For special listening applications, it may be desirable to reduce the overall operating range if:
• The audio transmission is to be contained to a smaller listening area;
• The signal is too strong and it is overloading the receiver
• Multiple transmitters are used in adjacent rooms where the FM signals overlap each other.
In these cases, the power level can be reduced to -10 dB or -20 dB. The output may be temporarily set to off to
help troubleshoot interfering or overlapping Radio Frequency signals.
