3.- CH 1 - PAGING MIC: priority audio input for dynamic microphone (MIC), condenser microphone
(PHANTOM 48 V) or lines (LINE), balanced combo connectors (XLR and 6.3 mm jack) and eurolock.
Once the input type has been selected with the MIC/PHANTOM 48 V/LINE selector, the gain of the
input can be adjusted with the GAIN control.
4.- VOX CH 1 - CH 3: setting the sensitivity to make the CH 1-3 inputs priority over all other signals.
Depending on this setting, the signal level required at the CH 1-3 inputs to cut audio from other sources
will be higher or lower. If the VOX control is set to minimum, no audio will be cut off from any output
when there is signal on CH 1-3. Please note the order of priority of the amplifier inputs, for more
information see section CONNECTION - PRIORITY OF INPUTS.
5.- EMERG. INPUT (100 V LINE): 100 V audio input for connecting an emergency system, euroblock.
6.- BASS: boosts/attenuates low frequencies.
7.- TREBLE: boosts or attenuates high frequencies.
8.- REMOTE MUTE: mute/unmute the speaker output remotely with the help of a switch, euroblock
connector. This input is in open circuit, to silence it you must close the circuit.
9.- LINE OUTPUT: line output, 2xRCA connectors.
10.- SPEAKER OUTPUT 120 W RMS: 4 Ω low impedance speaker output and 120 W RMS 100 V line,
threaded connectors. Please note that the choice of low impedance speakers must conform to the
amplifier specifications for serial or parallel connection (only parallel for 100 V line) to obtain power and
impedance appropriate to the amplifier output.
11.- 115/230 V amplifier power supply input.
12.- AC SELECT: power supply voltage selector. If you need to change the voltage you should be aware
that the fuse must be modified as specified on the product.
BASIC OPERATION
Select the operating mode using the INPUT control on the amplifier front panel.
AUX 1/AUX 2 INPUTS
-
Select the desired mode by having the signal connected to the corresponding connector input on the
rear panel of the amplifier.
-
Activate the audio device (player, mixer, PC, smartphone, etc.) connected to the input to start playback.
NOTE: make sure that the signal from your audio device is loud enough to be heard through the amplifier.
This allows you to control the volume from the amplifier itself at a later time without having to operate any
other equipment.
