6.- LINE OUT: aux line output. Signal output for recording, mixer, power amp, etc., 2 x RCA connectors.
7.- AUX: aux input. Input for signal source, allowing connection through RCA connectors from audio
sources.
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 3: pre-amplified
microphones, CD, tape, tuner, etc.
MIC: in this position, 30-600 Ω dynamic low impedance microphones can be connected to microphone
inputs 1 to 3.
PHANTOM 24 V: in this position, electret condenser microphones which require 24 V phantom power
supply can be connected to inputs 1 to 3.
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 be automatically attenuated
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/SEN control clockwise to its maximum (maximum priority).
10.- TEL: LEVEL: TEL. INPUT volume control. This allows volume adjustment of the telephone switchboard
which is connected to the TEL. INPUT terminals. Turning the control clockwise increases the volume
and anti-clockwise, decreases it.
11.- TEL. INPUT: telephone input terminals. This allows the connection of a telephone switchboard to make
announcements from the switchboard with priority over the rest of inputs. Consult the switchboard
characteristics in order to adjust the amplifier input level. The signal level can be adjusted with the TEL.
LEVEL control on the back panel.
Note: the amplifier is supplied with priority deactivated. In order to activate this function you must turn
the MUTE/SEN control in a clockwise direction to its maximum (maximum priority).
12.- Output terminals for aux speaker, 1 W 8 Ω - 600 Ω (Monitor): output terminals which allow an
external speaker to be connected as a monitor. It has a 1 W internal amplifier available. It will only
monitor the AUX IN input, controlled with the AUX volume, and adjustable level with the LEVEL/MOH
on the rear panel.
13.- LEVEL/MOH: volume control for the monitor output. Turning the control clockwise increases the volume
and in the other direction, decreases it.
14.- INPUT 1 to 3: 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, CD, tape, tuner, etc.
Select the appropriate position with the switch, being careful to put 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/SEN controlon the rear panel 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 need 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 distributor or the FONESTAR technical service.
15.- 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.
