ISS Autostart function
TM
The signal sensing Autostart function of the 8010A
powers it up when playback begins. Automatic
powering down to standby mode happens after the
playback has ended. The power consumption in
standby mode is less than 0.5 watts. The monitor
will automatically and rapidly start up once an input
signal is detected.
There is a slight delay in the automatic power-
ing up. If this is undesirable, the ISS
can be disabled by setting the "ISS DISABLE"
switch on the back panel to "ON" position. In this
mode, the monitor is powered on and off using the
power switch on the back panel.

Sensitivity adjustment

The input sensitivity (playback level) of the 8010A
has two alternative settings, normal and -10 dB.
The normal setting is factory default and the low-
er, -10 dB setting can be selected by turning the
"SENSITIVITY -10 dB" switch on the back panel to
"ON". The output levels are 100 dB @ -6dBu and
90 dB @ -6 dBu respectively. Choose the setting
that gives the desired playback level and good
resolution of the volume control.
ON (-4 dB @ 200 Hz)

Tone controls

The frequency response of the Genelec 8010A
can be adjusted to match the acoustic environ-
ment by setting the tone control switches on the
rear panel. The controls are "Bass Tilt" and "Desk-
top". Table 1 shows some examples of typical
settings in various situations. Figure 4 shows the
effect of the controls on the anechoic response.
Start adjustment by setting all switches to "OFF"
function position. Measure or listen systematically through the
TM
different combinations of settings to find the best fre-
quency balance.
Bass Tilt
The Bass Tilt control offers three attenuation levels
for the bass response of the monitor, usually neces-
sary when the monitors are placed near a wall or
other room boundaries. The attenuation levels are -2
dB (switch 1 "ON"), -4 dB (switch 2 "ON") and -6 dB
(both switches "ON").
Desktop Control
The "Desktop" low frequency control (switch
3) attenuates the bass frequencies by 4 dB at
200 Hz. This feature is designed to compensate for
the boost often occurring when the monitor is placed
on a table or similar horizontal surface.
