DESCRIPTION

- PA amplifier.

- With phantom power supply and priority.

CONTROLS AND FUNCTIONS

FRONT PANEL

1.- INPUT 1-4 and AUX: controls which regulate the volume of inputs 1 to 4 and the aux input.

2.- BASS: reinforces or attenuates bass frequencies ±10 dB.

3.- TREBLE: reinforces or attenuates treble frequencies ±10 dB.

4.- MASTER: control which regulates the general output volume of all the inputs.

5.- OUTPUT LEVEL: LED indicators for the output signal level. It regulates the individual volume controls
of the inputs or the general (MASTER) output volume control so that the level does not exceed the green
LED indicators. The red LED indicators indicate saturation or a distorted signal which could damage the
loudspeakers or the amplifier.

6.- POWER: amplifier on/off switch.

REAR PANEL

1.- Ventilation grille: to ventilate the output stage.

2.- GND. Earth: screw to earth the amplifier to be used in the case of the mains connection not having one
incorporated.

3.- 115V/230V: power supply voltage selector.

4.- AC socket: for the AC power supply cable connection.

5.- AMP IN/PRE OUT: the connection bridge between the two RCA connectors communicates the output
signal from the preamplifier (PRE OUT) with the amplifier input (AMP IN).

6.- LINE OUT: aux line output. Signal output for recording, mixer, amplifier etc., 2 x RCA connectors.

7.- AUX: aux input. Signal source input, allows connection of audio sources via RCA connectors.

8.- LINE/PHANTOM 24 V/MIC: input and 24 V phantom sensitivity switches. These switches have 3 positions:
LINE: in this position, high level audio sources can be connected to inputs 1 to 4: preamplified

microphones, CDs, tapes, tuners, etc.

MIC: in this position, 30-600 Ω low impedance dynamic microphones can be connected to inputs 1 to 4.
PHANTOM 24 V: in this position, electret condenser microphones which require 24 V phantom power

supply can be connected to inputs 1 to 4.
Use this switch with the volume at its minimum to avoid noise.

9.- MUTE/SEN: control which allows priority to be activated/deactivated in the INPUT 1 and TEL inputs.
Turn the control clockwise to its maximum and the rest of the inputs will automatically attenuate when
a signal is detected in the INPUT 1 or TEL inputs. Turn it anti-clockwise and the priority function will be
at its minimum.

Note: the amplifier is supplied with priority deactivated. In order to activate this function you must turn
the MUTE/SENS control clockwise to its maximum (maximum priority).

10.- TEL. LEVEL: TEL. INPUT volume control. This allows the volume of the telephone switchboard which
is connected to the TEL. INPUT terminals to be adjusted. Turning the control clockwise increases the
volume and anti-clockwise decreases it.

11.- TEL. INPUT: telephone input terminals. Allow connection to a telephone switchboard to page from the
switchboard with priority over the rest of the inputs. Consult the characteristics of the switchboard in
order to adjust the input level of the amplifier. The signal level can be adjusted with the TEL. LEVEL
control on the rear panel.

Note: the amplifier is supplied with priority deactivated. In order to activate this function you must turn
the MUTE/SENS control clockwise to its maximum (maximum priority).

12.- Aux loudspeaker output terminals 1 W 8 Ω - 600 Ω (Monitor): output terminals which permit the
connection of an external loudspeaker as a monitor. It has a 1 W internal amplifier. It only monitors the
AUX IN input, controlled with the AUX volume, and adjustable level with the LEVEL/MOH control on the
rear panel.

13.- LEVEL/MOH: monitor output volume control. Turning the knob in a clockwise direction, increases the
the volume and in an anti-clockwise direction, decreases it.

14.- INPUT 1 to 4: microphone/line inputs which use a combined XLR and 6.3 mm jack connector, accepting
balanced and unbalanced microphone signals of 30-600 Ω and balanced electret condenser
microphones which require 24 V phantom power supply in pins 2 and 3 of the XLR connector. They
accept high level line signals, balanced or unbalanced, from mixers, CDs, tapes, tuners, etc.

Select the appropriate position with the switch, being careful to set the volume controls at their minimum
to avoid noise.

The microphone 1 input has the priority function, which cancels all other inputs to give priority to paging,
emergencies, etc. The amplifier is supplied with priority deactivated. In order to activate this function you
must turn the MUTE/SENS control, on the rear panel of the device, in a clockwise direction to its
maximum (maximum priority).

CAUTION: when connecting or disconnecting an unbalanced microphone it is necessary that the switch
is in the MIC position. If the switch is in the PHANTOM 24 V position it could damage the microphones.
When using microphones that do not require phantom power supply, make sure that the switch is in the
MIC position, as the voltage present in pins 2 and 3 of the XLR connector could damage the
microphones. If in doubt, please consult your supplier or the FONESTAR technical service.

15.- OUTPUT: loudspeaker output. For the connection of loudspeakers in low impedance 4 Ω and in high
impedance 100/70/25 V lines. Connect the line of loudspeakers between the COM terminal and the
required impedance or V line.

16.- DC Power Input: 24 V DC power supply terminals. For the amplifier to work with 24 V power supply,
batteries, emergency power supply systems, etc. Make the connection with 2.5 mm² section cable to
the – negative and the + positive terminals.

Note: when the amplifier is used with 24 V DC, the power is reduced by approximately 20%.

CONNECTION

Make the connections with the amplifier and all the components of the audio system switched off and
disconnected from the power supply.
Firstly, connect the audio sources to the inputs. Connect the loudspeakers to the loudspeaker outputs. Use
the 4 Ω low impedance output or the 100, 70 or 25 V high impedance lines, according to the type of
loudspeakers you are going to connect. Do not use both types of output at the same time.
If you use the low impedance output, you must connect the loudspeakers in a series/parallel circuit so that
the load impedance of the loudspeakers is the same as the amplifier output impedance and that the power
supplied by the amplifier does not exceed that withstood by the loudspeakers.
If you use a 100, 70, or 25 V high impedance line output, you must connect all the loudspeakers in parallel
and the sum of the power of all the loudspeakers must not exceed the power supplied by the amplifier.
Once the connections have been made according to your needs, connect the system to the mains and turn
it on. After use, do not forget to switch the device off and disconnect it from the mains.
