SPEAKER SETUP
5. The Auto Detected Speaker screen will appear on
the video display. The M80 Front Panel Display will
read: ROOM/EQ SPKR:LFE BASE SPKR LEV. During
SmartEQ, the M80 will alternately send test tones to
the connected speakers. The Auto Detect screen will
show which speaker is being tested by highlighting
the appropriate speaker icon in blue and indicat-
ing which speaker is being tested on the Status line.
The Front Panel Display will indicate which speaker
is being tested as SPKR:LFE or SPKR: FL, etc. As the
dierent tests are executed, the SmartEQ screen and
Front Panel Display will change to indicate which test
is being performed on which speaker.
Checking Noise Level
Starting with the Subwoofer, the M80 will alternately
generate test tones to the sub and Front left speaker.

This test allows the M80 to analyze the ambient room noise and set an appropriate test level.
Checking Number of Speakers
Starting with the Front left speaker, SmartEQ will send a test tone out of each speaker terminal. This will conrm to the
M80 the speaker conguration and that the speakers are properly connected. Observe the test position on-screen in case
of a connection problem. If no tone is generated from a particular speaker, after testing all other speakers SmartEQ will
try the ‘missing’ speaker(s) again. If no tone is picked up by the microphone the Speaker not found screen will appear.

Step 3.
Checking Speakers Distance
Starting with the Front left speaker, SmartEQ will send a series of test tones to each speaker. The M80 will analyze the
delay from when each tone is generated to when the output from each speaker is received by the measurement micro-
phone. SmartEQ will automatically adjust the output delay to each speaker until all speakers have the same response
time. This will compensate for less than ideal speaker placement if all speakers are not equal distance from the Ideal
Listening Zone. This will assure sound from all speakers is heard at the same time for focus, creating a natural sounding
audio environment.
Checking Speakers Level and Size
Starting with the Front left speaker, SmartEQ will send a series of test tones to each speaker. The M80 will analyze the
output level from each speaker as received by the measurement microphone. SmartEQ will automatically adjust the out-
put level to each speaker until all speakers have the same volume. This will assure proper balance of voice, music sound
track and ambient sound to reproduce surround and multichannel eects as created in the studio and proper balance of
synthesized surround eects.
During the Speakers Level and Size tests, Smart EQ will also analyze the frequency response from each speaker to de-
termine its size. Size in this case does not refer to the physical size of the speaker itself but to the ability to produce low
frequencies. A ‘Large’ speaker would be considered a speaker capable of reproducing frequencies below 150Hz. A ‘Small’
speaker would typically be a satellite type speaker or small (physically) bookshelf speaker that has limited or no low fre-
quency output. (Check speaker specications for clarication.) SmartEQ will send test tones to the Subwoofer and to each
of the front, surround and back speakers and set appropriate crossover points for the sub relative to the rest of the system
and then each speaker based upon the sub crossover point and that speaker’s low frequency response. This will assure
seamless transition from lower midrange information to bass information. A properly tuned low frequency crossover
point and sending low bass frequencies to a powered sub also creates a cleaner and more ecient system with the front,
surround and back speakers being less likely to ‘bottom out’ trying to produce bass frequencies at the lower end of their
range at high levels.
