The Solution
Located about 150 miles northwest of Detroit and about 30 miles
east of Lake Michigan, Newaygo, MI, lies along the banks of the
Muskegon River. The town’s modern history began when French
explorers and trappers paddled up the river in the mid-1700s.

Newaygo decided to install an audio system in its 2-square mile
area to encourage tourists to visit its downtown merchants.
“The sound system positions the town to attract tourists coming
north,” according to Brad Hummel, Foreman for Nieboer Electric,
Fremont, MI, who supervised installation.

Residents wanted announcements for local annual events, which
include eight parades, outdoor concerts, farmers’ markets in the
summer as well as music during the holidays. Years ago, town
employees would have had to install speakers in the spring and
detach them in the fall to prevent damage to outdoor equipment.
Bogen’s NEAR speakers can be installed outdoors year-round with-
out damage to the speaker cabinets, mounting hardware nor inner
workings of the speaker.

The city of Newaygo wanted three zones for flexibility. The zones
include the Main Street, the upper parking lot and the lower park-
ing lot. The bandstand is in the southern upper parking lot and the
farmers’ markets are located in the northern lower parking lot. By
having three zones, suitable music and messages can be directed
to a specific zone. The Main Street zone serves well for parades
and the Annual Log Fest. The Main Street zone is about 2,200 feet
long and 60 feet wide (both sides of the street). The parking lot
zones are roughly square, about 250,000 square feet.

System Components
One Bogen M-Class Power Amplifier (M300) was selected for the
Main Street Zone. Two M-Class Power Amplifiers (M450) were
selected for the upper parking lot zone and a third unit (M450) is
used for the lower parking lot. The M-Class amplifiers can be set for
any of three modes of operation: stereo, 70V mono or dual mono.
For this installation, 70V mono mode was selected because of the
large quantity of speakers in the system and the power required to
run them, as well as the long distances of the wire runs.
