This step sets the nominal output level of the ZONE Outputs to match your room
audio equipment. This step also lets you mark the maximum room loudspeaker
amplification level permissible without violating the room acoustic gain limit.
i. Adjust the Zone output levels to match external amplifiers. Check the specifica-
tions of your room audio amplifier input:
• If it expects consumer level (-10 dBV) input, adjust the Zone output gain to
-8 dBu (-10 dBV = -7.8 dBu).
• If it has a balanced input connector and expects 0 dBu input level, adjust the
Zone output gain appropriately.
ii. Select pink noise output source. This is the Zone that will output pink noise for
microphone calibration. Choosing both Zone A and Zone B together will cali-
brate both zones at the same time to the same level.
• The default choice is pink noise played in both Zone A and Zone B.
• Choose “Pink noise to Zone A” for pink noise in Zone A.
• Choose “Pink noise to Zone B” for pink noise in Zone B.

Note.
The Zone output gain is also adjustable from -20 dBu to 0 dBu
using the UP and DOWN arrows on EFPanel.
