Other Reinforcement Uses
The EM-Mixers can be used successfully i in a wide
variety of sound reinforcement applications. Combined
with a pair of Yamaha 50112Т or other compact
speaker systems, and a roll-around podium, an EM-Mixer
makes a great portable sound system for a school,
library, banquet hall or meeting room. Plug the line-level
sound output from a portable film projector into one
channel, and adjust the Input Level switch to suit the
projector's output level. Connect microphones and/or
a tape recorder's Play outputs (line out) to other input
channels, and adjust each for the best tonal qualities.
The flexibility and economy of the EM-Mixers make
them attractive for permanent installations, too. Use
connections similar to those diagramed for Club Sound
Reinforcement Systems. These mixers are especially
useful for permanent multi-projector/recorder setups
(like slide, 16mm film, and filmstrip with additional
cassette and reel-to-reel audio sources). To minimize
hum and high-frequency losses, avoid long microphone
cables, or use low-impedance microphones with the
optional "Balancing Transformer Modules" on the
EM-150HB, EM-200B, & EM-300B; or use in-line
matching transformers. Always use heavy gauge
speaker cable, and keep microphone, speaker, and AC
power lines well separated.
You can feed another PA system (one with low
or high impedance inputs) from the EM-Mixer's Line
Outputs or its Monitor Outputs. For a mono feed to a
. PA system with a low or high impedance input, use
either Monitor Output. If you want a balanced feed to
a remote mixer, use a "direct box," or a transformer.
