from obstructions minimizes reflection surfaces and maintains
accurate localisation because reflections are symmetrical.

placement positions.
Stand-Alone Functionality
Bass Roll-Off Control
The Bass Roll-Off setting reduces bass level for spaces with
strong low frequency reverberation. It reduces output near the
low cut-off. Attenuation can be selected by combining settings
on one or more switches.
Desktop reflection compensation
The desktop control reduces frequencies near 160 Hz by 4 dB.
This compensates the boost when the monitor is placed on a
meter bridge or table.
Bass Tilt Control
The Bass Tilt control offers three attenuation levels for the
response below 800 Hz. This control is used when monitors are
placed near wall or room corner. Attenuation can be selected by
combining settings on one or more switches.
Treble Tilt Control
The Treble Tilt control adjusts the high frequencies above 5 kHz.
It corrects bright or dull sound and compensates high frequency
loss when a monitor is placed behind a screen.
LED Disable
This switch turns off the front panel LED light.
ISS
This switch activates and deactivates the ISS power saving
function when the 8361 is used in a Stand Alone mode. The
default time for going to power save mode is 60 minutes, but
this can be adjusted in the GLM software.
Digital
The Digital switch selects the digital audio signals A and B carried
in one AES/EBU cable. Turning on both switches reproduces the
sum of the signals. When both are selected, a 6 dB attenuation
is applied to avoid an overload.
Level
The Level switches reduce the monitor output in 10 dB steps
(-10 dB, -20 dB and both switches -30 dB). The switches
combine with the rotary level adjustment. The total adjustment
range is 42 dB. GLM software enables wider level adjustment.
Stored
The Stored switch selects between the controls on the monitor
back panel (OFF position) or applying the settings stored in the
monitor using the GLM software (ON position).
Operating Environment
This product is designed for indoor use only. The permissible
ambient temperature is 15-35 degrees Celsius (50-95°F) and
relative humidity 20% to 80% (non-condensing). To prevent
condensation after the product has been in a cool environment,
wait at least one hour before opening the packaging and
connecting the mains power.
Cooling of the 8361A must be ensured. The minimum
clearance behind, above and on both sides of the monitor is 50
mm (2 in). When 8361A is installed in a recess, the recess space
must be ventilated sufficiently to remove the heat.
