DESCRIPTION

T

he model MX-4000 is a professional mixer/preamplifier with 5 input channels to 4 output zones with
independent volume control. It is suitable for P.A. and sound system installations with different speaker zones
which need independent volume control.

It counts on 4 balanced mic. Inputs or selectable lines, 1 auxiliary line input and 1 tel. paging telephone
switchboard input assignable to each output channel. It has phantom power supply incorporated and priority
d

epending on the signal level in input 1 and tel. paging in inputs 1, 2 and 3 depending on contact closure.
There are LED indicators available to see the output level of each channel.

CONTROLS AND FUNCTIONS

FRONT PANEL

1.- CH1 to CH5 (GAIN, TREBLE, BASS, VOL, ZONE SELECTOR): input zone controls with the following

functions:

GAIN: to adjust the input gain, it lets you control the signal level in a way so as not to produce distortion.
TREBLE, BASS: bass and treble tone control.
VOL: to adjust the output level of the input that is sent to the allocation matrix.
ZONE SELECTOR, Z1 to Z4: these controls let you assign the input signal to one or various output

zones. To assign an input channel to one or various output zones, press the output zone (Z1 to Z4)
buttons in the corresponding input channel, through which you wish it to be listened to.

2. - PHONE VOLUME: headphone output volume control.

3. - LED MONITOR output signal level indicator.

4. - ZONE 1 to ZONE 4: output zone controls, zone 1 to 4 with the following functions:

LED output signal level indicator.
MON: by pressing this button you can monitor the channel signal through the MONITOR output.
VOLUME: zone output level adjustment.

5. - LED Power indicator.

6. - PHONE: headphone output to monitor the output channels assigned to MONITOR.

7. - MONITOR VOLUME: MONITOR output level adjustment.

8. - On/off switch.

BACK PANEL

1. - 115-230 V: power supply voltage selector.

2. - MONITOR (LINE OUT): line level output to monitor the output.

3. - MONITOR (1 W, 8 Ω): output for the connection of an 8 Ω low impedance speaker to monitor the output.

4. - PRIORITY: priority in the input channels CH1, CH2 and CH3. By closing these contacts the priority is
activated in the input channels CH1, CH2 and CH3. In this way the rest of the input channels (CH4 and
CH5) are weakened.

5. - TEL. PAGING, ZONE and VOLUME: telephone switchboard signal input with volume control and
priority depending on signal level with 4 switches to choose the zones to assign them to.

6. - Microphone inputs/CH1 line: these inputs use a combo connector (XLR and 6.3 mm stereo jack).
Balanced and unbalanced microphone signals and microphones that require phantom power supply, as
well as balanced or unbalanced line signals can be connected. Using the switch the input is adjusted
depending on the characteristics of the connected signal. These switches have 3 positions:
LINE: in this position, line level audio sources such as a preamplified table microphone can be
connected to inputs CH1 to CH4.
MIC: in this position, balanced or unbalanced, dynamic or electret condenser battery powered
microphones that do not need phantom power supply can be connected to input CH1 to CH4.
PHANTOM: in this position, electret condenser microphones that need phantom power supply (48 V
between pins 2 and 3 of the XLR connector) can be connected to inputs CH1 to CH4. Use this switch
with the volume control at its minimum to avoid damage.

7. - Zone, line out Bal./Unbal: line output for each zone (ZONE 1 to ZONE 4). Balanced line output
Euroblock terminal to connect the zone output signal to an amplifier.

8.- AC power supply socket.

9.- 24 V DC: connection terminals for DC current.

10. -CH5 LINE: auxiliary line input for CD, tape, Tuner, etc. connection, 2 x RCA connectors.

CAUTION: when you connect or disconnect an unbalanced microphone, the switch needs to be in the MIC
position. If the switch is in the PHANTOM position it could cause damage in the microphones. When you use
microphones that do not need phantom power supply, make sure that the switch is in the MIC position, as
the voltage in pins 2 and 3 of the XLR connector can damage the microphones. If in doubt consult your
distributor or the FONESTAR technical service.

CONNECTION

Make the connections with the amplifier and all the system components switched off and disconnected
from the power supply.

Firstly, connect the audio sources to the inputs. For example, connect a dynamic microphone to the CH1
input and select the MIC position on the input sensitivity selector. If you use a pre-amplified table
microphone, select the LINE position.

Depending on the speaker zones that you are going to use, connect each Zone output terminal, line out
Bal. /Unbal. to the line 1 input amplifier. Then connect the speakers to the amplifiers correctly.

Once the connections have been made according to your needs, connect the system to the mains and
switch it on. After use, do not forget to switch it off and disconnect the system from the mains.

INSTRUCTIONS FOR USE

ON AND OFF

Before switching the system on, check that the output volume controls are at their minimum. Switch on the
rest of the audio system, lastly the mixer/preamplifier and adjust the output volume. To switch the system
off, adjust the output volume and switch the mixer/amplifier off, leaving the rest of the system until last.

INPUT CHANNEL ALLOCATION TO OUTPUT ZONES

Each input channel CH1 to CH5 can be allocated independently to one or various output zones ZONE 1 to
ZONE 4.

Using the zone selector buttons Z1, Z2, Z3, Z4 for each channel, found on the front panel, you can choose
the zone where you want the input channel signal to be sent.

For example, if we intend CH1 to be heard in zones 1 and 2 and CH2 in zones 1 and 3, we must select Z1
and Z2 on the CH1 zone selector and Z1 and Z3 on the CH2 zone selector.

PRIORITY IN THE INPUTS

The priority function automatically weakens the level of the inputs with less priority so that the message sent
out by those with more priority can be heard clearly.

The inputs with the maximum priority are tel. paging and CH1 and they are activated by signal level. At the
same time CH1 has priority through contact closure.

To enable the priority function depending on the signal level and on contact closure, you have to change the
jumper. This is found on the inside of the device in the ON position. The jumper is on the printed circuit plate
which is near the connector with the MONITOR outputs, the PRIORITY contacts and the tel. paging input.

We can see where it is found in the following photo:

EN

In this way, with the jumper in the ON position, when a signal is detected in the tel. paging input or CH 1
the rest of the inputs (CH2 to CH5) will weaken. Besides, closing the PRIORITY contact on the back panel
with the push button or the switch, the CH2 to CH5 inputs will be weakened automatically.

NOTE: By default, the amplifier is delivered with the jumper in the OFF position. In other words, with priority
deactivated.
