High/Low output setting
The maximum output level of the headphone amplifiers can be switched between +8 dBu or
+16 dBu . The +16 dBu setting provides loud output for high impedance/low sensitivity head-
phones . For low impedance/high sensitivity headphones, the +8 dBu setting is advisable to
avoid ear blasting levels . The output level setting can be set for both headphone outputs indi-
vidually .
X Go to SETTINGS → AUDIO OUTPUTS and scroll down to OUTPUT MAX LEVEL under HEADPHONE
1 and HEADPHONE 2 .
You can even reverse the signal polarity for each ear cup on each headphone output . Reversing
one earcup (temporarily) can be useful to check for wiring mistakes . Reversing both cups is a
useful option for some older headphones that came with reversed polarity . Correct polarity is
crucial for singers in front of a microphone, so the electric path is in phase with acoustic path
(air, skull bones) .
Crossfeed
When listening on headphones, the signal on the left channel will only reach the left ear, and
the signal on the right channel will only reach the right ear . With loudspeakers this is not the
case: The signal on the left speaker will also reach the right ear and the signal on the right
speaker will also reach the left ear .
This can be simulated via crossfeed: Part of the left channel is also fed to the right ear cup,
and part of the right channel is fed to the left earcup . Listening on headphones thus becomes
more like listening on loudspeakers . The amount of crossfeed can be adjusted from 0% (no
crossfeed) to 100% The default setting is 0% .
X Go to SETTINGS → MONITORING and scroll down to HEADPHONES CROSSFEED .
Please note: The Crossfeed setting affects both headphone outputs .
