Chime On/Off
Switching on the manual chime on/off (10) switch on the rear panel and the priority conditions,
chime function will be activated ( "Ding-Dong" pre-announcement chime) when the priority override is activated.
The default volume of the chime is pre-set at the factory and should be suitable for most applications.
Power In & Pre Out (21-22)
These sockets connect the mixer/preamplifier stage to the power amplifier stage. The connecting link must
be plugged in for normal operation as a mixer/amplifier. If a compressor/limiter, equalizer, or other external
signal processor is used in the sound system, connect the "PRE OUT" to the input of the external processor
and the output of the processor to "POWER IN" In the signal chain, "PRE OUT" is after the tone controls
and the master volume control.
Loudspeaker Connection
This device provides two different types of loudspeaker outputs :
High impedance lines (25/70/100V) and low impedance (4, 8, 16 ohm), you can only use one of these outputs at
any one time, any attempt to use two or more of these may result in damage to the amplifier.
Loudspeaker Direct Outputs
PA 240 USB/R provides direct outputs according to the designed use:
- High impedance lines (25/70/100V)
- Low impedance (4, 8, 16 ohm)
These outputs, give an output at all times, reproducing any input signal into the amplifier (INPUTs 1-5,
USB/SD interface). The chime and priority functions affect these outputs.
