GENERAL DESCRIPTION
The ZM75 mixer provides an ideal solution for small
to medium size commercial sound system installations.
The ZM75 features a built-in constant voltage power
amplifi er capable of running at 25, 70 or 100 volts,
or at 4 ohms.
The ZM75 provides 75 watts of clean power. Six
input channels with individual level controls are
provided, so connecting sound sources is simple
thanks to the available XLR, 1/4-inch and RCA
connectors. In addition, the ZM75 features fi ve
selectable speaker zone outputs.
The ZM75 is ideal for distributing music and
announcements throughout different rooms and the
dedicated paging microphone input allows you to
setup a distant paging station (for a hostess in the
restaurant, for example). There’s even an on-board
chime with four selectable tones to alert the
listeners of an upcoming page.
For businesses that want to improve their customers’
telephone experience, a MOH (Music On Hold)
facility is also included. When interfaced with
a business telecom system, music or valuable
pre-recorded announcements are heard while
customers are on hold.
To control the overall tonal response of the sound
system, the ZM75 employs a seven-band graphic
equalizer. A master level control and fi ve-segment
level meters allow you to set a clean signal at the
correct volume. For added fl exibility you can add
the optional Samson TCM-3 sound module with FM
tuner and CD player that can play MP3 recordings.
The ZM75 can stand table-top or be mounted in
a standard 19-inch equipment rack using the included
rackmount ears. The sleek black fi nish matches just
about any décor, plus the steel chassis adds to its
durability and reliability. Perfect for schools, restaurants,
offi ce buildings, small factories, or just about any place
high quality, distributed audio is needed, the ZM75
offers excellent sound and great value.
