Feedback Reducer
The Shure
DFR22 is a two-input, two-output digital audio processor with feedback
®
reduction. The 2 x 2 matrix mixer allows either or both inputs to be routed to either or both
outputs, with additional controls for levels and polarity. The unit stores sixteen presets and
provides 24-bit conversion, 48kHz sampling, and a minimum dynamic range of 100 dB.
Distribution Amplifier
The Kramer VM-1610 Distribution Amplifier is a four-input, twenty-output splitter/distribution
amplifier capable of providing twenty discrete balanced outputs from two or four
balanced line-level inputs. Channel 1 L/R and 2 L/R Level controls affect the overall level
of each input.
ADA Hearing Assist System
The Listen
LT-800 Stationary Transmitter in the audio
®
rack allows individuals to experience every word at
an event. This system is designed to broadcast the
audio signal throughout the facility. It is capable
of transmitting to multiple receiver types and its
adjustable receivers allow each user to have full
volume control.
The Listen LT-4200 Portable FM Receiver (Figure 10)
provides users with the choice of 57 channels
and accessory options ideal for a wide range of
applications. The receivers are digitally tuned so
transmission will not drift, assurance that when you
select a channel it stays on the channel.
Note: If more receivers are required and the transmitter is already
installed, additional receiver packs and headphones are
available to purchase.
Wireless Personal Stereo Monitor System
The Shure
PSM
900 Wireless in-ear monitor system is used for on-field/
®
®
on-stage talent. The system includes a transmitter in the audio rack
and a receiver (Figure 11) worn by the performer that allows for
personal adjustment of mix and volume and compensates for delay
from the sound system.
Sound travels at 1120' (341 m) per second. This produces a
noticeable delay as one moves away from the speaker. Even
experienced performers have trouble adjusting to this delay. A
wireless in-ear monitor system provides a real-time signal to the talent
and blocks the sound delay from their ears.
Note: If more receivers are required and the transmitter is already
installed, additional receiver packs and headphones are
available to purchase.
