System Status Indicator (Beam Logo)
White: System is powered and in standby
Blue: System is powered and ready/active
Flashing Red: System fault, over temperature fault
OFF: System is off and not powered
NOTE: UPON INITIAL POWER UP, THE SYSTEM WILL UNDERGO
A BOOT PROCESS THAT MAY LAST A FEW SECONDS. NO
AUDIO WILL BE HEARD.
Zone Status Indicators
OFF: zone is not active (system is off or in standby)
WHITE: zone is active and ready. No signal is present or is
too small to be detected
BLUE: zone is active and detects an input signal
FLASHING YELLOW: zone is active but is overdriven
RED: zone is in protection
AC POWER SOCKET
The 16-50 and 8-50 feature a removable IEC power
connector for the AC socket. Plug the female end of the
power cord into the AC Power Socket on the amplifier
rear panel and plug the male end into a grounded
wall socket. Do not plug the amplifier’s power cord
into a convenience outlet on any other audio or video
component. If you need to use an extension cord, use
only a heavy duty (14 gauge or larger) extension cord to
avoid starving the amplifier of the current necessary for
full operation.
TRIGGER MODE CONTROL
You can set the amplifiers so that they will automatically
turn ON when it receives an audio signal, when it receives
a control voltage from an external source, or to remain on
and not enter standby.
NOTE: IF EITHER AUDIO OR VOLTAGE TRIGGERS ARE
SELECTED, THE AMPLIFIER HAS A LESS THAN ONE SECOND
CYCLE TIME FROM STANDBY TO PLAY AN AUDIO SIGNAL. THIS
IS NORMAL AND REQUIRED TO COMPLY WITH THE EU <O.5
WATT ERP DIRECTIVE. SELECT OFF TO BYPASS THIS FEATURE.
SEE POWER CONSUMPTION TABLE FOR IDLE POWER USE.
Auto On Triggering - Three Position Switch
AUDIO -
In this mode, the amplifier will automatically
turn ON when the minimum audio signal of 1mV is
detected at any of the selected inputs (Local and/or Bus).
This trigger takes less than one second to activate. The
amplifier will turn off after 15 minutes of no input signal
on all selected inputs.
VOLTAGE -
When the Sense switch is set to voltage, the
amplifier will automatically turn on when a voltage of
3-30V DC is detected. Connect the trigger voltage source
to the input of the V Trigger using the left side of the
green block connector. This trigger takes less than one
second to active.
Figure 2: Amplifier Powered on 24/7
Connect a two-conductor wire from the 12 volt output of
an AV receiver, zone amplifier, or control system to the
voltage trigger IN. Voltage trigger OUT provides 12VDC
anytime the amp is active. Do not exceed 100mA of
current draw. Damage can occur.
LINE INPUTS/LOOP OUTPUTS
The amplifiers have BUS IN and THRU connections
and zone-specific IN connections. The zone-specific IN
connections are typically used with a multi-zone preamp
to provide zone exclusivity.
BUS A and BUS B
To share one or two audio sources internally with more
than one zone, the amplifier has BUS A and BUS B IN
and THRU connections. The BUS inputs are useful for
blending auxiliary sources together, such as for paging
announcements and door chimes along with the audio
source connected to the local inputs. Note: The paging
and doorbell chimes cannot mute the local audio source
- they will all be heard together.

OFF -
When the Sense switch is in the top OFF position,
the amplifier will remain ON and will not go into standby
mode.
NOTE: WHEN THE AUTO ON SWITCH IS SET TO OFF THE
AMPLIFIERS POWER SAVING FEATURE WILL BE DISABLED.
12V Trigger Output -
The Sonance amp has a 12V Output
two wire screw connector found on the right side of the
green block connector that provides 12V DC whenever
the amplifier is ON.
1. OFF/Power Switch: Useful if the amplifier needs to
be always on without any delay between signal input
and sound output.
2. Voltage Sensing: Optimum sensing option as it is
impervious to false triggering and 100% predictable.
3. Audio Sensing: Simple option that controls the on/off
state with the audio signal.
