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 NPUT 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 NPUT 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. n order to activate this function you must turn
the MUTE/SENS control clockwise to its maximum (maximum priority).
10.- TEL. LEVEL: TEL. NPUT volume control. This allows the volume of the telephone switchboard which
is connected to the TEL. NPUT 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. n 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. t has a 1 W internal amplifier. t only monitors the
AUX N 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. n 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 M C position. f 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
M C position, as the voltage present in pins 2 and 3 of the XLR connector could damage the
microphones. f 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%.
