Helping People Hear

AUDIO PROCESSOR SWITCH

Selects one of the two modes available.

LIMIT MODE

The audio processor has little effect on low level sound. As the level increases, reaching

the point at which the red +6 LED lights, no further increase in transmitted level is

permitted. This is necessary to prevent distortion in receivers and prevent interference

with other channels. Limit produces a very natural sound, and is most desirable for

music. High quality speech signals are also very pleasant to listen to. However, Limit is

not as helpful for hearing impaired individuals as Compress mode.

COMPRESS MODE

At high levels, 0 to +6, Compress is very similar to Limit. But at low levels Compress

increases the volume substantially. Hearing impaired people need an increase in low

level to be able to hear most speech.

Compress is most useful for hearing impaired individuals and in those situations where

the input signal is either poorly controlled or has great dynamic range.

MODE SWITCH

The Mode Switch selects how the channels are used. Separate processing for each channel is

provided in Discrete mode, where the two channels have unrelated program material such as

two different languages. Coupled processing is provided for Stereo mode, where the

program material is related.

DISCRETE MODE

The channels operate fully independently. Carrier timers operate separately, allowing

one channel to go off without affecting the other. The Phones jack receives one or the

other channel, as selected by the Phones switch. Both channels of the Phones jack have

the same signal.

STEREO MODE

Audio processing is coupled, providing a consistent stereo image, important when

listening with headphones. Carrier timers are coupled, requiring both to have reached

approximately 30 minutes before either carrier can go off. Both carriers go off and on

together. The Phones jack receives stereo sound, one channel in the left side and the

other channel in the right side. The Phones switch is deactivated.

PHONES

The phones jack monitors the transmitted audio signal. It is designed to accommodate

standard professional headphones with a 1/4 inch plug. It can also accept any other type of

headphone or earphone. Headphones with 3.5 mm plugs can be used with a 1/4 inch to

3.5 mm adapter.

IR LED

Infrared receivers can be tested using the infrared LED. This LED is of short range only,

useful to about 1 meter. The infrared signal emitted from this LED is modulated by the

carriers generated in this unit only. If this modulator is connected to other modulators for

additional channels, their carriers are not emitted by the LED, and must be monitored at

those modulators.
