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.

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.

AUDIO INPUT

The MOD 111’s input accepts any low impedance microphone or line level signal. The input

circuit is constructed with a “studio grade” differential amplifier, providing better

performance than that available using a transformer. It is also fully protected from RFI/EMI.

MICROPHONE

Any dynamic, ribbon, or condenser microphone equipped with a balanced output and a

3 pin XLR connector can be used. Power is supplied for condenser microphones

according to DIN 45596. It need not be turned off for dynamic or ribbon mics.

Microphones with two conductor 1/4 inch plugs are not usable.

The minimum acceptable level is approximately 100 µV, and the maximum level before

clipping is approximately 90 mV.
