HISTORIC DISTRICTS

The Challenge

•

Provide year-round sound outdoors for a town

of about 620 households

• Sound system must withstand colder than normal temperatures,

higher than normal wind speeds and an average

of 28 inches of snow in December and January

• Allow crew with limited sound experience to easily install

and connect audio equipment

• Install sound system so that any of three zones can receive music,

announcements and paging

• Ensure uniform sound throughout the zones

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.

The sound system equipment of main components is allocated

as follows:

Zone 1 (Main Street)

• 56 NEAR

A-Series Speakers in black (A2TBLK)

• 1 Bogen M-Class Power Amplifier (M300)

• 1 Bogen Gold Seal Series (GS35)

Zone 2 (Upper Parking Lot)

• 38 NEAR A-Series Speakers in black (A8TBLK)

• 2 Bogen M-Class Power Amplifiers (M450)

• 1 Bogen Gold Seal Series (GS35)

Zone 3 (Lower Parking Lot)

• 20 NEAR A-Series Speakers in black (A8TBLK)

• 1 Bogen M-Class Power Amplifier (M450)

• 1 Bogen Gold Seal Series (GS35)
