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.
