A long press of this button allows the playback mode to be selected among: random playback
(RAN), repeat one track (SIN), repeat folders (FOL), repeat all (ALL.
In radio mode, this button lets you change successively among the stations saved during automatic
tuning
q: player module on/off button.

SIGNAL: LED signal presence indicator.
10.- LED power indicator.
11.- Aux input, 3.5 mm jack connector.
Note: this frontal aux input is the same as the one on the rear panel (AUX).
12.- Aux input or USB/SD/MP3 player selector.
13.- ZONE 1: control that regulates the output volume of zone 1.
14.- ZONE 2: control that regulates the output volume of zone 2.
15.- POWER: amplifier on/off switch.

115 V/230 V: power supply voltage selector.
2.-
FM: antenna input for the digital FM tuner.
3.-
GAIN: 100 V line input signal level control.
4,-
LINE/PHANTOM 24 V/MIC: input and 24 V phantom power supply sensitivity switches. These switches
have three positions:
LINE: in this position, line level audio sources can be connected to the inputs: CD players, etc.
PHANTOM 24 V: in this position, electret condenser microphones that require 24 V phantom power can
be connected to the inputs.
MIC: in this position, the inputs can be connected to low impedance 30-600 Ω dynamic microphones.
5.-
AC power supply.
6.-
GND: earth screw, to be used if the mains does not have one incorporated.
7.-
Loudspeaker output. For connecting loudspeakers in 4 Ω low impedance and in high impedance
100/70 V lines. Connect the loudspeaker line between the COM terminal and the impedance or line in
the required volts (V).
8.-
Zone output terminals (COM - Z1 - Z2): terminals to connect the loudspeaker lines of zones 1 and 2.
With the zone selection terminals only loudspeakers with 100 V line transformer must be used. The total
connected power in loudspeakers must not exceed the power of the amplifier. Connect the positive of
each zone to the corresponding terminal Z1 and Z2 and that common to all the zones to the COM
terminals.
