Altec Studio Monitor Speaker Systems are
designed to meet the stringent specifica¬
tions of extended frequency response,
low distortion and wide dynamic range
that are required for use in recording and
broadcasting studios. The bass loud¬
speaker (woofer) produces extended low-
frequency response even when driven at
exceptionally high power levels. Two fre¬
quency adjustment controls (high and
mid-range) are provided to adapt the
Studio Monitor Speaker Systems to a
wide range of acoustic environments,
including audition rooms, recording studio
control room monitoring, remix studios,
mastering rooms, broadcast studio moni¬
toring and playback, auditoriums, night¬
clubs, conference rooms, theaters,
churches, and other professional
applications.
All of these Studio Monitor Speaker Sys¬
tems combine excellent overall band¬
width, low distortion, uniform dispersion
and extended frequency response. Major
differences between the larger (Model

19 and smaller (Model 15 systems are
sensitivity, acoustic output and enclosure
size. For applications where sensitivity
and acoustic output are of major impor¬
tance, the larger Model 19 should be
used. Where space is at a premium and
slight reduction In sensitivity and
acoustic output is not detrimental, the
smaller Model 15 becomes the logical
selection.
Wall or Ceiling Mounting
For many professional applications the
Studio Monitor Speaker System is hung
or suspended from a wall or ceiling. A
recommended type of installation utilizes
four V4 "-20 eyebolts which are secured
in the sides of the cabinet with flat
washers and nuts. The low-frequency
loudspeaker must be removed to install
the eyebolts. The Studio Monitor Speaker
System is then suspended by the four
eyebolts with a lightweight chain (200-
pound pull) from anchor points in the wall
or ceiling. Baffle angle of the monitor may
be adjusted by raising or lowering one
pair of supporting chains at the anchor
points. Figure 1 illustrates a typical
ceiling-mounted system. When the cabinet
Is hung 'bass-side-up', the network/
equalizer assembly may be removed,
rotated 180 degrees, and reinstalled to
maintain a right-side-up orientation.
Optional Mounting Base
If the discriminating listener wishes to
use the Studio Monitor Speaker System in
the home environment, the optional
mounting base may be secured to the
bottom of the cabinet. To install the
optional mounting base, position your
Studio Monitor Speaker System on one
side or the top, using a carpeted surface
to protect the finish of the cabinet. DO
NOT lay the system on its front side,
because the grille coverings may be dam¬
aged. Position the base against the bot¬
tom of the cabinet, rubber feet facing
outward, aligning the pilot screw holes.
Install the supplied screws (No. 8 x
