USER’S MANUAL
8. Options: by clicking on this item, a drop-down menu appears with the
entries shown in the image:
Signals: lets you set how AP F8.9 bit is turned on through:
• Turn ON by SPEAKER DC (ART): when Enabled is selected, AP F8.9 bit can
be turned on through the amplified output (BTL) of a source connected to
the inputs FL-FR-RL-RR.
This function can be disabled by selecting Disabled.
• Turning ON by SIGNAL PRESENCE (AST): when Enabled is selected,
AP F8.9 bit can be turned on through the presence of a
signal from a amplified
source connected to the inputs
IN1, IN2, IN3, IN4, IN5, IN6. The stand-by time
(energy saver) for the device when there is no signal can be set through the
function TIMES -> SLEEP time out for analog input
(see next point). The shut
down time for the device when there is no signal is set to 30 mins. This
function can be disabled by selecting Disabled.
Times: Lets you change the settings for the times to turn AP F8.9 bit on and off.
• Remote OUT delay (sec): this is the delay between disabling of
the REMOTE OUT signal to the amplifiers and turning off AP F8.9 bit. It is
not usually necessary to change this parameter but it may be useful to
decrease it whenever there are amplifiers that produce a turn off "Bump".
• MUTE release delay (sec): this is the delay between turning on the device
and the activation of the output audio. Each amplifier has a turn on phase,
its own delay before being operational. Setting Startup Time to a value
equal to or greater than the longest delay will provide synchronized audio
startup for the whole system.
• SLEEP timeout for analog input (min): it sets the amplifier’s stand-by time
when there is no audio signal. The stand-by time (energy saver) can be set
from 1 min minimum to 20 mins maximum. Normal operation is resumed
when the audio signal is present. This function is set on 20 minutes by default
and can be enabled by selecting the desired amount of minutes.
The SLEEP timeout for analog input function allows to save power and
provides the ability for the product to work at lower temperatures.
Remark: we recommend that the shortest possible activation time is selected in case
of hybrid or electric propulsion cars; it won’t affect the product normal operation.
• Wake delay from sleep (sec): it sets the amplifier resume delay from energy
saver status. The delay time can be adjusted from a minimum of 0 sec. to
a maximum of 5 secs. This function is set by default at 0 secs (disabled).
Remark: some factory (OEM) head units are provided with a control signal lasting
approx. 2 secs during the turn-on phase to check if loudspeakers are in the system
(see section 4.3). If the head unit is turned off while the car is being used, the AP F8.9 bit,
if turned on through ART, will keep working to let the security alerts, phone alerts,
navigation system alerts etc. be reproduced . When the head unit is turned on again,
the speaker presence control alerts may be reproduced. To avoid this happens, you
can set the Wake delay from sleep (sec) duration at a value slightly higher than the
duration of the speaker presence control alerts.
