ENGLISH USER MANUAL
SYNQ®4/5 SE-1100
•When the output signal has reached a high level which can result in distortion (clipping). Meanwhile
the current limiters come in action to reduce the dynamic range (current) of the output and bring the
amplifier back to its safe working range. In this case you are urged lower the input!
6. PROTECT LEDS: The protection LED is on in the following situations:
•During the first second after switching on the amplifier.
•When the temperature of the power stage becomes too high.
•In case of a technical defect: DC protection!
•While switching the amplifier off, the “protect led” turns on for a short time.
7. MAINS SWITCH: Used to turn the amplifier on and off. A few seconds after switching on the amplifier it is
ready for operation.
FUNCTIONS (rear)
8. MAINS INPUT with PowerCON®compatible socket, connect the supplied mains cable here.
9. MAINS FUSE: protects the unit in case of electrical problems, always use the prescribed 20x 5mm fuse!
10. FAN & VENTILLATION HOLES: during its operation the amplifier produces heat that must be dissipated.
The fans inside the amplifier must be able to evacuate the heat in the most effective way. Therefore, is it
very important not to cover any of the ventilation openings as this may result in overheating.
11. L+R SPEAKON OUTPUTS: use these Speakon®compatible connectors to connect your speaker cabinets
(impedance >4ohm) in stereo or MONO mode. Wiring of these connectors is as follows:
•CH1: POS(+) = PIN1+ and PIN2+ NEG(-) = PIN1- and PIN2-
•CH2: POS(+) = PIN1+ NEG(-) = PIN1-
12. BRIDGE OUTPUT: use this connector to connect your speaker cabinet (impedance >8ohm) in bridge
mode. Wiring of this connector is as follows:
•POS(+) = connector PIN1+
•NEG(-) = connector PIN1-
13. OPERATION MODE switch: Used toset the operation mode of the amplifier. The most common operation
mode is “STEREO”. If you need more power, you can operate the amplifier in BRIDGE mode. In MONO
mode you only have to connect the left input to drive both outputs. Refer also to n° 3 for more information.
14. INPUT SENSITIVITY SWITCH: you can choose 3 different input levels: 0,7V / 1V / 1,4V
15. BALANCED XLR OUTPUTS: Can be used to send the signal to the next amplifier. Pin1: signal ground,
Pin2: signal+, Pin3: signal -
16. BALANCED XLR INPUTS: Pin1: signal ground, Pin2: signal+, Pin3: signal –
HOW TO USE
STEREO OPERATION:
•Connect the audio signal to the inputs (15 or 16)
•Set the operation mode switch (13) to “stereo”
•Connect the matching speakers to the L+R Speakon®compatible outputs
(11)
•Make sure the mains voltage matches 230Vac before connecting the mains
cable to the earthed wall socket.
•Set both input gains (2) to zero
•Make sure there’s a music signal at the input
•Turn the amplifier on (7)
•Adjust the input gains (2) to the desired level
BRIDGE OPERATION:
•Connect the audio signal to the left input (15 or 16)
