In venues where a House PA is installed or a much larger system has been provided,you could use the amplifiers
of the Horizon to power the stage monitors.Use the AMP ASSIGN switch(39) set to A1 and A2 and connect the
MIX XLR outputs to the house PA system.AUX 1 and 2 can now be used to set up two separate stage monitor
mixes.Two 8 ohm monitor speaker can be used on each amplifier output.

35.Play Back
Controls the incoming signal from the USB (56) and Play Back (57) inputs and routes the signal to the L-R
MIX faders.
36.MIX Bargraph Display.
An accurate 12 segment, two colour display giving a visual representation of signal levels. In normal use
shows the signal level after the L-R MIX faders prior to the internal amplifiers and Mix output (65) sockets.
The bargraph will automatically display the signal level from any PFL/AFL switch when pressed.
The signal displayed on the bragraph can also be heard on headphones (43).
37.AMP bargraph display
A 13 segment, three colour display giving a visual representation of the output of the internal power amplifiers.
The calibrations shown alongside the bargraph are an indication of the power output when a 4 ohm impedance
speaker load is used.
The red LED marked 1000W indicates when maximum power has been reached. It should only illuminate on
signal peaks and not remain on continuously as distortion, speaker damage or over heating of the amplifiers
may occur.
38.AMP POWER switch.
This three position switch can adjust the signal available to the internal power amplifiers and lower the power
output to the speakers. In the 100% position, full power is available. At 40% power is reduced to approximately
400W, 15% approximately 150w. This is referenced to a 4 ohm speaker load.
This can be useful in applications such as conferences, lectures etc. where full power is not required yet the Mix
faders still have a useful range for precise signal adjustment.
Caution: Due to the dynamic nature of music this feature can only be used as a guide to amplifier power output.
Only loudspeakers rated for the full output of the Horizon should be used.
39.AMP ASSIGN switch
This switch determines what signal sources feed the internal amplifiers.
L R position
: This is the normal setting. The left Mix signal is routed to the left amplifier, the right Mix signal
routes to the right amplifier.
A1 L-R position
: In this setting both left and right Mix signals are joined (mono'ed) and fed to the right amplifier
only. The left amplifier now receives the signal from the AUX 1 send output. An application for this could be
supplying the main PA speakers from the right amplifier and the stage monitor speakers supplied from the left
amplifier.
A1 A2 position
: The left amplifier is assigned to the AUX1 output and the right amplifier assigned to the AUX2
output. This would make both the internal amplifiers dedicated for stage monitor mixes. In this situation the left
& right Mix outputs maybe routed to a House PA or maybe a larger format PA system and the AUX output used
for stage monitors.
40.POWER LED
Illuminates when the Horizon is switched on.
This is for applications requiring more power and/or more low frequency sound reinforcement.Activate the
100Hz X-OVER on the Horizon by pressing the button (45),confimed by the yellow LED illuminating,The full range
left and right speaker are connected to their respective speaker outputs on the Horizon but now they will only
receive frequencies above 100Hz. Dedicated sub bass speaker (powered or by an additional amplifier)can be
connected using the MIX2 output which now only feeds frequencies below 100Hz.if only a single bass speaker
is used, connect to the L/MONO socket on the MIX2 output.Set up your Horizon in the usual way and adjust
the L-R MIX faders to the required volume,Slowly turn the MIX2 level control and you will hear the low
frequencies filling in the bass end of the system.
