10 ExtroNews 14.3 Fall 2003

The Extron MVC 121 is a high performance

microphone and line level mixer with volume

control. It includes two microphone/line level

inputs and a third line level only input — each

with its own volume control. The MVC 121

also features:

• RS-232 control and contact closure muting

• Line level outputs

• 48V microphone phantom power

• Front panel LEDS

• Two modes of front panel security lockout

The Extron RAC 104 is a four channel remote

volume and tone controller. It provides up to

four channels for controlling volume, bass, and

treble. The RAC 104 features:

• RS-232 control and three presets per channel

• Compatibility with any audio ampliﬁer

• Professional and consumer audio levels

Both the MVC 121 and RAC 104 include

external power supplies and are housed in 1U,

quarter rack width metal enclosures for ﬂexible

mounting under or through a desk or in a rack.

Applications

The MVC 121 and RAC 104 can accommodate

up to four audio channels while optimizing

sound reinforcement in integrated A/V

environments. Figure 1 is an example of a

two-channel application with two front

program speakers and two podiums, each with

its own microphone. With the MVC 121, the

user is able to provide a stereo input for an

audio source and inputs for two dynamic

or condenser microphones. Volume can

be controlled for each

individual input and the

mixed program output.

In Figure 2, a three-

channel application

comprises two channels

for program speakers

and a third channel for

distributed ceiling speakers.

The RAC 104 allows the

user to deﬁne the channels

as mono or stereo. The line

level selection DIP switch

also enables the user to

choose between consumer

or professional level inputs

and outputs. The RAC 104

can control the volume,

bass, and treble of program

speakers. It can also control

the volume and tone of a

third channel for the

distributed speakers placed

on the ceiling. A similar

scenario would apply to

Figure 3 with the addition

of a fourth channel. In this

instance, however, instead

of indirectly inputting a

microphone into the third or

fourth channel, another external audio source

could play background music on both channels

in stereo.

Figure 4 is another example of a four-

channel application. The difference here is that

channels three and four are now assigned to

zones. The user can control the tone and

volume in various parts of the room, often

resulting in an even distribution of sound

throughout the entire area.

xtron has been making a little noise in the audio world. We now offer more switchers with key audio features

such as preamp line level audio for ﬁxed and variable outputs and integrated audio ampliﬁers. We have

developed specialized audio products that enable additional processing control for program and distributed audio

systems. At InfoComm 2003, three new audio summing ampliﬁers were introduced for converting two-channel

stereo audio signals to balanced/unbalanced one-channel mono audio signals. Now, we have added two more

products designed for the integration A/V market: the MVC 121 audio mixer and the RAC 104 remote volume tone

and tone controller.
