LEVELS CALIBRATION
Properly calibrated output levels are critical. Setting output levels is
a simple procedure using a Sound Pressure Level (SPL) meter. This
device measures the relative loudness of the speakers so that
output levels can be calibrated accurately. An SPL meter can be
purchased at Radio Shack (catalog no. 33-2050).
To ensure the most accurate calibration levels:
• Eliminate extraneous noises in the listening space, such as
conversation, air conditioners, and sounds that filter in from
open doors and windows.
• Remove objects (including people) that obstruct the
line-of-sight path between the SPL meter and the speaker
being measured.
• Measure output levels from the primary listening position,
placing the SPL meter at the approximate spot where the
listener’s head will be during listening.
INTERNAL NOISE TEST
Selecting either INTERNAL NOISE TEST or EXTERNAL NOISE TEST
accesses the SPEAKER LEVEL ADJUST menu
(pictured above). When INTERNAL NOISE
TEST is selected, a cautionary message
(pictured at the right) will appear on the
screen. This serves as a reminder that the INTERNAL NOISE TEST
generates loud calibration noises. When the message appears,
press the right MENU arrow to proceed to the SPEAKER LEVEL
ADJUST menu. Press the left MENU arrow to return to the LEVELS
CALIBRATION menu.
