7.1 | manual system access & tuning
Spectra i.Net® System will automatically default to the acoustical
handbook’s preferred curve.
Using a quality sound level meter to check the setting:
•
Set the entire environment at 47.5 dBA as measured four feet above the finished
floor. You can make adjustments using the Sound Manager or hand-held remote.
For fine tuning
•
Leave all of the ceiling tiles that have an OP hanging above them exposed so that
incremental adjustments can be made with the hand-held remote control prior to
closing up the ceiling.
Use the hand-held infrared remote to make immediate adjustments to the volume
and contour of each channel (A,B,C, and D) at each OP. You may press the ALL button
on the remote to tune an entire OP if all of the speaker channels are in “like space.”
Aim the infrared remote control at the OP and press either the ALL button
(All Channels), or an individual channel, A,B,C, or D.
The LCD display will read the following for each:
Button on Remote = LCD Display
All = AL
A=A
B= b
C=C
D=d
B
D
A
C
NOTE
This measurement should be accomplished in the
evening or after normal working hours and the ceiling tiles
should be 90-95 percent installed for an accurate reading.
